I think this is the ONLY KZfaq video which compares these 3 cameras with actual wildlife photos. Amazing!

Mark, I went with the D500 and D850. For me, it was a no-brainer. I'm heading towards the end of my own life, so planning for the next 20 years is nuts. And for me, the cost of replacing all my F-mount lenses to go with the Z-range of mirrorless would have been simply horrific - altogether TOO much. The Z-range, and Canon's and the rest of the mob, will no doubt make heavy inroads into the DSLR market. But in my lifetime, or what's left of it, they're unlikely to see the same range of lenses and other accessories I already have. For someone starting now - maybe. For me - too little, too late. I can already get everything I want, with gear I already have. Theres nothing in it, for me to make the switch.

This is THE best description of the Z7’s AF issue in tracking and I have read many. Thank you.

This is the best review of these 3 cameras!! Thank you so much!! Can't wait to come to one of your workshops!!

D850 wow! Incredible micro details on that rabbit shot is amazing

Mark, amazing photos! I just ordered the Nikon D500 and the Nikon 200-500 5.6 vr lens thank you. And the soonest I receive my order I will watch your video on the set up for the Nikon D500. Keep up the good work and one day I will go to a workshop with you.....

Mark - Love the picture of the Osprey at 7:13 with the wings spread and sort of floating on the water

Awesome shots, narrative, and camera information. Thank you.

Mark, thank you for making and sharing this comparison video. It's really helpful to see how these cameras perform in the same use case and under similar conditions.

First time watcher. Great video man. I liked your example shots and commentary. I'm currently in the research phase of my next camera, so this was helpful.

Great stuff Mark as always. Osprey shots were phenomenal. You need your own TV show. Keep it up, someone will come after you. You're a great bio-storyteller.

Excellent video. Thanks for posting.

I set up my D850 for BBF using the AF-ON button and assigned the group focus to one of the buttons on the front. It's a great way to switch between using single point, my default setting to group focus.

Your a WONDERFUL KZfaq Photography person! I feel I'd like to use another term but I couldn't come up with one that conveyed that precisely like that one did. I'll keep watching your stuff for sure! Keep doing your wonderful work!

Mark, Thank you so much for your informative videos. I have learned a tremendous amount and spent a tremendous amount. Since finding your content Iv'e bought the D850, D500, and 200 500.This video really shows the strengths of the 3 amazing cameras. Props to you !

Great video as usual!! I'm eyeing a D500 myself and this review is really helpful. Plus I could watch vids of you shooting the Ospreys all day long!

Wow! Those Osprey shots were breathtaking! Great comparison too!

Mark, this was a great comparison of the cameras. This has been a big help to me in making my decision about which camera to focus on. Thank you.

Amazing, beautiful... LOVE YOUR VIDEOS! This video is very useful, not to mention they're a feast to the eyes. I love your enthusiasm in your commentary. Thank you for inviting us to cherish these intimate moments with nature.

Mark, Great review and Amazing shots. There were clearly some real money shots there. Keep burning those pixels. ~ your neighbor

Mark, you're doing such a great job with birds shooting. You're one of my best youtuber. Thanks to share and make me sick each time !

Awesome video and review as always Mark. I’ve got the D850 and D810 both great cameras. I just purchased your D850 setup guide. Thanks for putting these together.

I liked the variety of cameras you chose to compare but what I like even more is that you admitted to being out of the focus area on the osprey. I wonder if firmware updates could help with reacquiring subjects and the EVF lag. Nice review.

Awesome comparison of the three cameras, the image(s) that I like the most are the first couple pictures of the Osprey flying into the water you took with the D850. Ref @ 4:50+ minutes in. They are amazing images.

Excellent comparison video, Mark. And, as always, I enjoyed your commentary.

Wonderful images!

Great job Mark. Love the comparison and the zoom ins. Great great shots. Jim

Thanks for a very educational video, I use the D500, but a D850 for christmas had been nice

What a great review. Thank you! And yes so lucky to live near the osprey feeding area.

Another great video Mark thank you for sharing your adventures.

Thanks Mark, great video. Confirms what I think about my D500 - a great all-round camera.

Excellent video Mark. Thank you. I use a D500 and a D800. - Mike McIntosh

Very nice! The D850 was really showing off here. The detail in its images were stellar

Excellent comparison. I appreciate your candor and the testing results.

Great video Mark, amazing shots!

I'm seriously researching for the purchase of a wildlife setup in the very near future and I really enjoy your videos.

Mark, I bought the D850 with the kit lens (24-120) and 70-200 2.8E combo. Trying my hand and I am loving it. Some of your work has inspired me and am an admirer of your channel. Thanks for the no bs content, straight to the point discussion and brilliant explanation of the composition.

Another great video mark. Well done with the double header.

Great video! Enough to make me subscribe as a matter of fact! I’m loving my Nikon D500 and especially its incredible autofocus system!

Thank you Mark for another fantastic video. I really like and appreciate your clear and unbiased comments on the performance of the three cameras. Having your insight into the performance of these three cameras will be very helpful for any prospective buyer of any one of these cameras. My favorite series of photos from this video were the ones with the osprey with two fish. Thanks again for this video and keep up the good work.

Thanks for the comparisons! Great captures!

I quickly hit subscribe after watching your video. Really great "in action" comparison of all three cameras. Thanks!

Great comparison. Love my D500 but I'm liking the images from the D850 too. Thanks for a great review. Good job.

Wow! I bought d850 and will test in field very soon. To me, i find all all the photos you shared incredible, but will favor osprey with two catches! Thanks for sharing your review!

Amazing pictures with phenomenal cameras! Bravo!

Thank you so much for this review comparing the Z7 with the others.

Outstanding video Mark. This helps me with my decision about a Z7. Thanks a million. Bill

Great comparision. jaw dropping skills of Mark-Amazing !

Mark, awesome review as well as your set up guide. I purchased the D500 last fall and your set up guide brought me up to a whole new level. Thank you for your tips and suggestions when photographing birds in flight. I have yet to capture Osprey on the feed, however, I have lots of in flight shots. Especially that brief hover upon arrival to the nest. Oh, one more thing, the Male Osprey's bib is less prominent than the Female's bib. Keep up the excellent work, CHEERS from Ontario Canada EH

Love your videos its one of the best youtube photography video Ive come across keep it going.

Another amazing video!!! That shot with the 2 fish is craaaaaazy! That tells you that bird is the boss.

Thanks Mark, amazing comparison and photographs.

Mark -- You are by far and away the best You Tuber when it comes to wildlife photography and putting your superb images together with the stories of each one. Incredible! Keep it up! :)

Interesting comparisons. Thanks for sharing. I use to live in sw Florida. You have some amazing photos.

Congratulations on capturing that double fisted Osprey fish catch. Amazing.

Great video and comparisons. I am interested in the D850 v Z7 and already have the D500, so very helpful. Thanks.

Thanks for the great video. I own a Nikon D610 and want to upgrade, love to photograph sports, portraits and last month landscapes. Seeing this video my preference goes to the Nikon D850.

Subscribed. Like your real world testing and love your passion about the animals.

Great job with the comparison Mark. Thanks, as always for your efforts! Would you consider making a "Long lens technique" video in the future? Thanks as always!

Thanks for another enjoyable video Mark. Although you said it was more technical, I totally enjoyed the all the pictures and especially the narration (is that a word?).

Thanks for a very educational video, I use the D500, and set it up in your tutorial video, it a brilliant camera for bird flight. Many thanks for you videos.

Absolutely great video! Thanks!

Great photos, and a fantastic way of how you compare these cameras. Too many favorite shots Mate

You're doing pretty good work. Well done. I'm looking forward to your next video.

helpful comparison i love that D850 specialy for his megapixels .

Solid comparison, excellent captures!

A very informative video, Mark. Well done.

Thanks for more real world shots comparing these cameras. The pic with two fish was very cool, I've only seen a couple of other photographs with two caught at once by an Osprey. You got a rare and wonderful shot. I also like the very last shot with the Z7 with the bird flying straight at the camera.

Great comparison and detail about the auto-focus results with the three cameras. I mostly shoot landscapes and so chose a Z 7 for the better dynamic range, lower noise in low light, and detail. I had heard in the 1st & early Gen firmware, the AF was a bit "hinky" to use slang but landscapes do not move a lot and if they do, it is time to duck for cover. But, thanks to your detailed comparison, I now know that, unless Nikon upgrades AF and viewfinder performance, I need to purchase a Z 6 body if I want to photograph wildlife under challenging conditions or risk missing great shots.

Thank you. I've been tormenting myself on whether to buy the 850 or Z7 and this is the best comparison Ive found yet.

Thank you Mark...I have learn alot with this presentation. You are one of my best !

Great review, Mark Smith!

Excellent video Mark!

Awesome shots and comparison video!

Very comprehensive video, as usual. The comparison is awesome and beautifully explained. 😍

Mark, thoroughly enjoy all your videos, especially the D500 (which I own). My wildlife photos are not anywhere near yours, but your videos give me great information when I shoot local Hawks, Ospreys, and seagulls. Thanks.

Uauuuuu sin palabras! Que gran trabajo, amigo!

Thank you for the video! And actually posting photos, that was incredibly helpful! I've been struggling to commit for months between the D850 and Z7. I shoot mostly wildlife and landscapes, but I do want to shoot more wedding/sports etc. to supplement my income. I keep reading and hearing that the Z7 is better at landscapes (and lighter and quieter), but the D850 outshines the Z7 in wildlife/wedding/sports. So it puts me at a stalemate, lol! But I have been leaning more towards the D850 because I also keep hearing that the auto focus in low light situations is awful in the Z7 compared to the D850. Would you say the D850 is better overall, or just for wildlife?

Hi Mark, Great videos and photos as always. Great to see that you can use a Z7 for wildlife photography, after all the negative comments elsewhere on other channels about the Z7's autofocus! Hopefully you will test the Z6 under similar circumstances and point out the differences between the Z6 & Z7 focusing systems.

Great in the field comparison of the AF features. I hope Nikon fixes the EVF lag in bursts mode, that can be a show stopper in certain situations.

Mark, please keep making your wife and kids do all the chores around the house so you can continue making these great videos. Another great one!

7:49 ¡Asombroso, dramático, genial!

Incredible shots as always. The one that blew my mind was the one with the D850 in front of the reeds with the bird sort of in back edge profile. No way I was thinking I so need a D850.

Really insightful vid... thanks for sharing

Nice Video, i liked how you described how the autofocus missed cause of the Wide Area AF Test, when the bird went out of AF Box on the z7. Keep Sharing your adventures, i personally love ittt...

You videos are so well done. I love your photos and the information you provide is thorough and easily understandable. I really agree with your assessment of these cameras. I have had a chance to use and experiment with a D850 and Z7. I personally still prefer a DSLR but it is my personal preference because I started out with SLR film cameras so likely just my familiarity with that format taints my preference. I am a hobbyist and use a D500 as cost is important to me and I like the extra reach this camera provides. If cost wasn’t an issue I likely would use a D850 as in DX mode is really is a D500. The D500 does have the advantage of having edge to edge focus points which I really enjoy. Presently I just don’t prefer mirrorless because of the EVF and also I like the body size and feel of a DSLR in my hands. The D500 has a nearly perfect body shape and button placement for me. Also like the D500 is very customizable which I try to use to my advantage. Again I totally agree with your assessment on the D850s stellar photo detail. It simply shines in that department. Keep your videos coming. I will keep watching.

Some of those 850 images were just amazing - besides the sharpness and colour and light, the action is brilliant

I just came across your channel looking for Nikon D850 videos. I’ve really enjoyed watching them and making my way through most of them. Great work! I’m only a hobbyist and always looking to improve. I used to own a D300 years ago but sold it due to circumstances. In the last few years got back into photography but decided to give Fujifilm a try. Been through X-T1, X-T2 and currently X-H1. I really like the Fuji but can’t say I’m overall 100% satisfied. I recently viewed my old Nikon D300 photos on Flickr and was surprised by how beautiful and clean they looked. So much so that I’ve been contemplating switching back to Nikon, more specifically the D850. Hence my interest in your videos. Only hesitation is obviously going from a reasonably light weight and portable camera system to a big bulky system ... decisions decisions

Hi Mark! Favourite shot, one osprey with two fish hands down one of my favourites of all time. Very much enjoyed the comparison, it was fair and informative IMHO and reinforced my decision to buy a D850 last year. Thanks for creating the Quick Start guide btw, it has been incredibly useful to me and I credit a much faster than anticipated learning curve as a result. Good light to you!

Thanks to you! After review your pics several times, I made up my mind to buy Nikon D850 and the telescope lens anyhow.

Outstanding Video, Mark !!

Great review 👽👍👍👍 and interesting insight into the viewfinder lag of mirrorless cameras with the possible recent exceptions of the Sony A9 (2) and the A7R4 when it comes to fast action in bird photography and some sports. Even many of your test shots are exceptional.

Great video, love the comparison. Still very happy with my D500, but the Z6 also has my attention.

Great review Mark !

Great shots Mark!!

great video.very interesting and informative. Thanks!

I thought this video provided an excellent comparison to all three cameras for wildlife photography. I loved the capture of the osprey with the Two fish, awesome!

Regardless of which cameras, those birds in flight pictures of yours are simply breathtaking.

Great youtube video do you go out every day and lucky you to live so close to a great location i love Ospreys we get small numbers of them passing through here in Ireland

You're amazing guy, thanks for explaining!
