Either camera is great for any situation. I'm gonna wait about 10 years so I can get one for 800 bucks lol.

No matter which camera you use, you always seem to end up with wild, vivid accuracy! Never blurred, always crisp focus! Nat. Geo quality!

I so appreciate all that you do with the skill sets you possess, Always a pleasure to hear you and your insights and to be a recipient of your stellar body of work over the years as well as your enthusiasm with the gear you use to paint your as well as others' monitors!!! Thank You for your Awesomeness and openness with sharing over the many years..... David

So many good cameras available today, great time to be a photographer and gear that costs 2500 today performs better than pro gear of 5 years ago costing $6-8000

The point is it isn't the gear, it's the photographer. :)

Thanks for the quiz. I like your factual, story telling videos including your settings and tutorial type videos vs. the guessing type video’s of late but it was still fun. Thanks Mark.

Beautiful images as always and an interesting experiment. Obviously, in the right hands, all three cameras can produce stellar images.

Stunning photos as always Mark. These guessing competitions are fun, but what I really would love is for you to show your post processing on one of these images. It's probably asking you to give away your trade secrets, but that would be so cool,

In the end I think either camera can produce a great image because I think the sensors and image pipeline are both very good. I am more interested to learn from you if any setup or AF configuration options or approach the camera supports made it easier for you to capture the great images you shared. Or does a specific lens with one system or the other work better for you, i.e. focus faster. So sharing that kind of info would

Please keep doing it. I just appreciate the opportunity to see all these great photographs.

Stunning images as always Mark, regardless of the equipment you use. Just shows that more important than your gear is improving your skills on how to use your camera and your knowledge of the subject. I prefer Nikon gear but personal preference aside, improving skills gets you better results, and the tools you prefer just add to the fun. Love your channel Mark and your images are beautiful.

All of your photos are outstanding, I love them all. All cameras today can take mindblowing fine pictures, of course the tool you use have a certain impact. But it is the "handcraft" that counts. It is not the camera. It is the cameraholder! The photos you took with the D500 were fantastic. So are the ones you take with Your A1. Pictures like yours takes good tools, but even more it takes knowledge, not just knowing the gear, but also the wildlife you shoot. For me, I like to see your wonderful images and how you shoot them - gear comparison not so much.

Both are very capable camera makers. Thanks for posting this.

Loved this type of video. Technology is amazing now and those just showcases that.

That was fun Mark! I vote to do more, but max 4-5 on this topic per year. I’d also, with deep respect, request you to provide some level of feedback. We pick models based on pixel peeping, so please bring some insight to the results. Tell us things you like or dislike about the photo and if it’s related to the camera. Folks who participated or liked this video are probably looking for insight on systems and models and how they perform.

You do great balanced content and such great advice. And amazing shots - I expect we will see you with millions of subs :)

I was right 🙂 with the last one. Waiting for my A7IV to arrive and to make my bird photgraphy a little bit easier.

I hadn't guessed, since I wouldn't know. But I Do know, they are All fabulous shots!

Can’t wait for the video set and operation for the the A1 … Thanks for your awesome channel, it’s made me a better photographer.

I can't tell whether it was shot on Sony or Nikon when i see a beatiful image of an osprey - but im pretty sure the picture was taken by Mark Smith!

Mark, awesome photos as always. We all appreciate you sharing your knowledge and experiences. On the last photo, I am assuming that you paired up your Sony FE 600mm with the Sony a7IV. Do you use lens filters on your Sony FE 600mm and Sony FE 200-600mm lens? Thanks again.

I'd like to see how you compare the Canon R5, Nikon Z7 and Sony A1 maybe in a table format after you've discussed all 3.

I always thought it could have been either camera.. I couldn't guess.. It's always dependent of on light and the camera settings you use.. I was mostly interested in which camera had the best hit-rate.. Which was easier to use.. Which had the least problems..

Hi Mark thanks for your video. Always enjoy watching your video. Question: is it good to put Teleconverter for 200-600mm Sony. ?

The pelican shot is super sharp and the colors are beautiful. I like these comparison videos!

Great Video Mark. Thank You.

Excellent video and I'd love to see more of these. I think it really removes some of the toxicity from the fan boys to see that most of today's cameras are capable of producing some unbelievable images...

Awesome work as usual!

Love the images, love your story telling about capturing the images, and believe your skill and your eye for nature is the key. So maybe not too many ‘which camera took this’ for me (though I guess highly zoomed in iPhone for your last Instagram story!)

I owned the Z9 and A1 in parallel for 3 weeks and was able to identify your photos with 100% accuracy. I ended up sending the Z9 back and kept the A1.

Love your vidéos . Injust got m’y a7r4.i could not sait another monte i feel well with it

Both amazing camera's, but for less than half I think the OM-1 will be my choice since I already have the glass. Besides I'm too old to carry all the weight around full frame lenses encumber one with.

Great video as always Mark . I think we all have learned something here. Both cameras are amazing but then any camera is amazing in your hands . One more think that a lot of you tubers could learn from you . You never feel the need say this camera bad , this camera good. They are all great. Your success proves that click bait negative and” oh my let me find one little thing wrong with this camera and exploit it “is overdone and people are tiring of these type of videos. Yes 2 things can be amazing!!

Both amazing cameras! :) fun way of comparing and really hard to choose the right one

Always enjoy your videos for what they are. Honest assessments of what you are using and photographing. I believe the current round of equipment has made a significant difference in your images. What do you think, Mark? (Yes, I know you have more knowledge now, but still). As for the guessing game video - it's fun, but not really helpful. I guessed the first two images correctly (but I've seen your previous videos) and was dead wrong on the last two images (wasn't sure what camera the last image was shot on). Thanks as always. Keep up the fun stuff and story telling.

Mark, Any early impressions of the Sony A7iv you can share? I almost bought it today. Just mailed off my slightly used Nikon Z6ii and kit lens for likely sale this am anticipating making the switch. I do all sorts of photography so birding is just one of its uses. Thanks, Craig

Awesome as ever. Phil

3/4 are A1 , I think you made your choice clear.

I think the most interesting part is the optics. Can you share the lens info as well?

These are great pics. Like I have seen so many others say in these comments, I too would be more interested in the technical side of the cameras, IE the settings and what you did to produce such great shots. I am not an experienced photographer, but I recently bought a Sony A6400 and would love to know how to take shots this good.

I'm way more interested in your feedback on which camera had a higher hit factor for you, which made it easier to get the best photos.

I got all guesses correct! Great images

I enjoy the opportunity to guess the camera body. Make a few more of this type of video. I think the last one is a Nikon BTW-I’m still shooting with a vintage,model, the original A9……

Interesting comparison but!!, I assume all these shots were taken in RAW. Any thoughts on which brand takes more post work to bring in the rich color and detail?

I am surprised by the A7IV. Wow.

Great stuff only shoot with the A1 so a bit bias here on "Camilla & I" !! 😍👍🤔

Thanks Mark. The Sony a7 IV actually does a very good job on that osprey action shot. What kind of hit rate did you find on the Sony a7 IV for these action shots ? This was fun and informative. 👍👏🏻🕊🐿😀 Thanks.

Are you coming to PA to shoot Saw-Whets? They hang mostly within the Appalachian Plateau. Great pics as always by the way..

Indeed, working with the flagships of the big 3 out there should not allow us, outsiders, to know what brand was used. It shows that, despite all the new features current cameras have, it is still the person behind the camera that has to tame the beast. Interesting experiment but the point is proven so time to move on (you asked our opinion ;) )

I guessed them all correctly! Probably because I have been using Nikon cameras for many years and the way I figured it out was only down to the blues of the sky and water, that's it! All great images anyway :-)

Hi Mark. Me again. Okay you e had more time with that Sony a7 IV. Images I’ve seen really impress me for sensor performance. How is the AF/ tracking for BIF ? I’ve read that it’s bird AF is inconsistent with birds in motion. What do you think El Maestro ! It’s price point is good for me. Can the Sony a7 IV cut it with either the 200-600 or 100-400 GM for amateur birding and BIF ? Thanks 😊

To me the camera that makes it the easiest to get the higher keeper rates for these types of photos is more important. Outside of how the camera feels in your hands, once the camera menus' are set-up & you get comfortable using it, it probably doesn't matter. From what I have seen the A74 would most likely have slanted items in it while panning depending on the what's in the photo. Still a great camera for the price point. Heck , I get some great photos with the D810 & 200-500 lens. Just have to work way harder for them with a much, much, much lower keeper rate. Did I mention the lower keeper rate!

When is the owl video coming out. Still wondering where in Canada you were filming owls. Thanks.

Mark now that you have the new a7iv do you plan to make a etup video like you did for the a1. That video was one of the most complete and comprehensive setup videos I have seen. I can't justify the cost of the a1 but I do own the new a7iv and would eagerly look forward to a setup video that also covered what works best for birding and wildlife.

I like this quiz. I think for extra guessing you should throw in an older photo from a camera you used to use and see if we can tell the difference between an old or a new camera.

I wouldn't even have a guess which camera in most of today's current lineups. They all make really good stuff - and for me it comes down to which I enjoy using the most (Nikon with Canon a fairly close 2nd).

Interesting! I guess it confirms what I have always thought; you can get superior images from almost any modern day camera. It's more to do with skill than the technology.

No point in trying to guess which camera. They all are fantastically good.

The test was interesting. I managed to choose photo 1 and 3 correctly. Nikon has been playing catch up to Sony with their mirrorless cameras, yet Sony has been playing catch up to Nikon with their photo color accuracy. It's a win, win for the consumers. 👍👍

Yeah, I’m out on the comparison vids. I love my a7iv and I’m looking forward to your forthcoming content featuring it, but you produce amazing work product regardless of the rig. No need to fall into the silly camera wars that way too many people seem to feed into.

The questions I have is what lenses were they captured on ?? Lol! Nikon has been coming out with some pretty cool lenses lately like the 400mm f2.8 with built in TC and the new PF 800mm 😊

wow Mark Amazing Photos as always... I got several wrong between Sony, Nikon! I did like the "guessing game"... I'm wondering about post production if thats influencing the color science or not... are the photos shown edited? Post changes the color/level ranges of the cameras and lenses, the sharpness of both seem to be great and of course you the photographer, take the images to a whole other level!! -You Rock!!

50/50 on my guesses too. Did you use a tripod or were you able to capture those images handholding? I hate using tripods unless it’s a nature shot.

Both are good shots

Love it.

Just like that for the reason that it shows one thing: All the brand bashing on the web has no substantial foundation. It is 1. the Photographer, 2. the light, 3. the lens and 4. the camera that makes the image. Maybe the lens and the camera come closer in sports & wildlife but they will never be more important than the person who takes the photo and the light.

I think cameras these days are all excellent as you show in this video. The most important aspect of photography is the photographer behind the camera. Of course we want to get the best camera that we can afford to achieve our purpose but these days some people care too much about the device itself. Some people even get too defensive and get angry trying to defend their favorite camera brand as if they work for the brand. Camera is just a tool to express yourself.

Your photos are great. Who cares which camera and what's the point of guessing at all? Good photography is not about the camera but who is behind it.

You should put some D500,D850 pics in there as well. I'd be curious if they hold up against the mirrorless camera's ( I bet they do).

La verdad es que las cámaras de hoy día están muy parejas en cuanto a resultado final. Son rápidas enfocando, tienen buena ráfaga de disparo, etc, etc. Para los que critican el color de las sony tan solo hay que ver ese pelícano con esos hermosos colores. Un gran vídeo con unas fotos de gran calidad.

I have the A7iv and really like the bird eye focus. How much better do you think the A1 bird eye focus is and is it worth the$4000 more??? I love your KZfaq channel!!

Mark are you going to do a review on Sony A7Iv?

I wouldn't be able to tell & feel most are just guessing. Outside of an extreme crop from 2 cameras, one being a 16-20mp & the other being 42- 50mp... Did you do any editing/color to the eyes in any of the osprey photos?

Hi, im relative new to digital photo, I bought an zfc and I love it, I have almost the money for the z9, should it go for it or the z7ii would do the job? I mostly take bird photos and cosplay portraits

3:10 No way! Wow! I thought it was a Z9 shot. Very good photo.

2:20 Wow, perfect shot.

Hello Mark. In case you used Z9 (v 3.0+) and a9 ii(v3) extensively side by side, can you share your opinion on their AF as a comparison?

Do you know the distances of your shots thru your camera? Do you use a range finder at all? The close up on the pelican makes me wonder how far away your camera was from the birds face.

Will share ;)

Great video ... good job 👍👍

Mark as your big fan and follower I need an advice from you... is it worth upgrading my Sony A9 for the Sony A1 ? Please

My wife works at a local camera store, so she gets to play with some of the gear when its slow. She prefers the Nikon but you can't go wrong with either one. Thanks for the great video.

Fabulous’ regards from Scotland

Heyy I have the Sony A1 and photographed ospreys for the first time today and some shots came out blurry while they were diving in for the fish I was at 5000 shutter speed. Should I have been on a higher shutter speed?

In general Nikon straight out of camera shots are colder with more hue of blue. Sony has warmer tones and more vivid colors out of the camera without any retouching.

Which camera would you rather have for BIF, the a74 or a7r4? (I have an a1 but wanting to upgrade wife’s a7r3 without spending $6500)

I’d love to hear your opinion on the OM-1.

When is the a7iv review please?

How about taking pictures with both cameras, and then see if we can tell the difference!

Wow, all of these shots - but man that last one, I absolutely LOVE it. The background color, the lines / flow, just amazing. All of these modern bodies are basically impossible to differentiate (as shown by all 50/50 tallies here). They're all SO much better than what I started with decades ago, we're now at level "bananas". Anything from here forward is just icing on the cake. And I love the 33mp sensor in Sony's new A7IV, I think that's a sweet spot. I'm in the Nikon system so I'm hoping their next lineup offers that "in between" resolution.

I am using D500 now and i want to buy nikon z 7 ii for bird photography, is it good enough?

Hey Mark. Do you use any type of filter on your lenses?

Do you prefer a small body like the a1 or a heavy body like the Z9?

Make a video on a7iv

I definitely guessed wrong on the image I commented on LoL. I for sure thought that second image was from a Nikon body.

Nikon for years…but no way my Sony setup is gonna leave my arsenal 😁

Well lol, I got the last one right with A7iv!

I got everything but the last shot right, I guessed the last one was from a D850. It was the colors that help my decisions, to my eye Nikon’s colors differ to Sony’s, to my eyes anyway. Of course the last shot fooled me, and I shoot with the D850. Thank for sharing some superlative photos, your work is astounding! All the best.

I think this video illustrates most of the latest cameras with good glass can produce equally great resulting in the hands of a master photographer like yourself. Interesting, but I prefer your regular videos. You are a great story teller. So I vote against further guessing videos.

Goes to prove - it's not the gear but the skill & artistry of the photographer.
