Thanks for reporting on the minimal focus distance (and visually showing it)! Most reviews don't do this!!!

Fantastic straight forward, informative, no bs review. Thank you. As a professional M43 user, I originally struggled to see the use of this lens, but I can definitely see it filling in some of the deficiencies of the Pana 14-140mm f.3.5 for a solid walk around travel lens.

i hate this style of review being not so popular on youtube because people expect storytelling review.. i really like you keep it simple and on point

I bought this lens with the new Olympus OM-D E-M1II, I love it...it fast and really works well in the stabilization department. Very sturdy and has a quality build/feel to it...JUST a great all around lens for me...A+ Review...

Very informative review, as always. Nice lens, good fit for the EM1MkII, but together they're around 2.500€. At that price there are other combos to consider, given that the size and weight are not that different and Olympus still has some drawbacks. But another great lens choice for people already in the M43 system. Take that, Sony.

And 4 years later, the price hasn't really changed, wow, it must be a good lens...

A really well delivered professional review, devoid of nonsense!

very helpful. very calmly and informed explained. great!

There is one lens which seems to be attractive for MFT, both as it is and both from a price point of view, but hardly reviewed - the Tamron 14-150mm. f/3.5-5.8. Perhaps you can comment or maybe even review it? I think many are interested in it!

Looks like a very nice lens. A bit pricey but it may be worth it for some. Great review. I liked the line that you drew to show the close focusing distances. Very clever.

Do you still have and use this lens? Do you still feel this lens as having room in the m43 universe, and does it still make sense in the current Camera and Lens universe with so many new releases? I ask this because I always had this lens on my radar and I always waited for prices to go down to buy it, but prices never went down and I never bought it. Do you still consider this lens a good buy as a travel and multiuse lens? We work with Nikon (Apsc and Z) and Olympus and have a lot of m43 equipment, including the Lumix 12-35mm f2.8 and 14-140mm and Olympus 40-150mm f2.8, which overlaps the 12-100. Thanks for another great review! You guys are amazing and have a very pleasant way to present your videos and talk! Competent, polite, affectionate with the audience and straight to the point. Thank you very much and all the best to you! My wife and I are photographers in southern Germany and we love your work.

It is a fantastic lens. One of my favorites. Good review.

Thank you! Great Review als always! Kind regards Marcel

I am a big fan of Olympus cameras and have been using them for sometime now. While I don't own the 12-100, I do use the 7-14, 12-40 and 40-150mm Pro lineup. I love the quality of all these optics with the 40-150mm f2.8 being my favourite. My only complaint is that while advertised as "freeze proof" the 12-40 f2.8 Pro gets very stiff at sub zero temperatures. I live in northern Canada and routinely venture out on lengthy winter hikes. In the past, I would take my E-330 and E-30, along with various Zuiko lenses, in temperatures as low as minus 40 C without ever experiencing problems. Last year, I took the OM-D E-M1 and 12-40 Pro out to film a sled dog race. It was a balmy minus thirty but the lens was impossible to zoom in that temperature. The zoom ring simply would not rotate without applying considerable force, something I did not want to do. This winter, I have taken it out into minus 15 degree temps, and while it works, the zoom ring is already displaying some resistance. It is interesting to me that the older plastic bodied optics such as the excellent 14-54mm f2.8-3.5 never demonstrated this sort of issue. I suspect the problem is a result of the metal bodies and it leaves me very reticent to use my 7-14 or 40-150 in those conditions despite the "freezeproof" claim. Have you tested any of these new lenses in similar low temperatures?

The Bokeh does look pretty good.

Purrfect reviews as always.

I had no idea how to use or why buying this lens. now this is my most used lens for everything except wildlife.

Great review!

Not a parafocal lens like the Leica 12-60 though so it will lose focus as you zoom. Seems to be the only drawback

Very nice review. Your voice sounds very professional :)

Great review, relevant even in 2023

I bought this lens and camera body on Halloween. What a great start to my Olympus journey. However, I disagree with you about the weight. Having lugged around a Canon dslr with a Tamron 100-600... need I say any more?

A great lense, but will this lens be difficult to use with earlier model like OMD Em5?

What song do you use in the beginning? Interesting lens, thanks for the review :)

Great review. Thank you. What is your guess of the overall performance of this lens on GH5?

The obvious question for me is, if this lens is everything which can be desired, what is the point of the 12-40mm lens? Presumably the point of that lens is that, with the shorter the zoom range, fewer compromises need to be made in its design - with the fewest compromises being with a prime lens.

Great review! Very well presented. In one graphic, it suggests the IS Sync is compatible with the EM1 (Mark 1). Does that mean the Mark 1 also achieves the 6.5 stops of stabilization that you get on the Mark 2?

Are you sure the minimum focus distances are measured from the focal plane of the camera, not from the front element of the lens, which is quite unusual in the still photo lens world?

thanks for nice review

Mathieu =LENS, .. M.Zuiko ED 12-100mm F/"4" Is F/4 Across The Whole Spectrum? Or as You Zoom OUT,..Does it Change & Start Going into => F/"4-0-5.6"? THANK You,

Thank you!!!! We need tutorials on the M1 Mark II please

Zuiko and Zeiss make the best lenses

Cheers from Torino...

ook in mijn bezit de 12-100 f4 een echte alles kunner , voor op vakantie is het echt een aanrader samen met de Olympus omd - em 1 mrk ii een heel fijn koppel ... groetjes Miel

I was hoping you would mention something about its comparable brethren. Its cost really makes buying a F4 lens a real stretch when you can buy an F2.8 Pro lens.

Hello good evening! I am really impressed with the images of the video, specifically with the photos taken by hand with exposures of 4 to 20 seconds. How do you get it? I have this lens a couple of days ago along with a new OM-1 and I can't take well-focused handheld photos with more than 2 seconds of exposure. How is it possible to take a photo of more than 4 seconds without moving the least bit and getting that sharp image? Help me please! This is going to take away my sleep and years of life :-P

You failed to comment if the zoom is smooth and has really continuous/constant exposure all the time, and how much it loses focus (since I don't think it's a parfocal lens).

Basically it's f8 lens. Correct?

Awesome review. I've been wondering about this lens and how it works with the Olympus and Panasonic bodies. Do you have info on how many stops of IS for different combinations?

You're awesome.

Do you live in Turin? I noticed many of your shots are set there and in several videos

If added to EM10m2, will it give 6.5 stops of stabilization? Also, would EM5m2 considered to be small body for this lens ? Thank you !!!

Thanks for vídeo. I wonder if I could have this same results of images stabilizations with my Oly omd em10 markii as others pro Olympus bodys.

hi there thamk you for video. one question, is it also compatible to use with em10 mark3 espeacially power IS feature? Many thanks...

Hello thanks very much for this great video. Kindly advice which lens of the two (oly 12-100 f4 & Leica 12-60 f2.8-f4) would be ideal for shooting mainly music videos and short films with GH5S if price and weight is not as issue? If Leica, then it will be kept constant at f4 most of the time. I like and prefer oly over Leica but someone suggested that Leica is optically better/sharper than oly pro lenses. Would that be true? I want to get one good zoom lens for now and will try to add cine primes later on. Kindly advice. Cheers.

I have a question about this lens. I know if you add it to EM1 Mark 2, you get 6.5 stops instead of 5.5 stops of IS. But what if you add it to lets say EM1 mark 1. Can you get 5 stops of IS instead of 4 stops. Another words, does it add 1 stop of IS to any body other than EM1M2 or it only holds true with EM1M2?

I bought the 12-100 F4, despite the F4 aperture (F8 FF equivalent). I made the plunge because I thought the built-in stabilization will offset the need for a fast shutter speed. But so far, the lens is very disappointing. After a month+ use, I find many of my photos are blurry (using with an Em-1 m1 body), but still.. it would make sense that any moving subject would be blurry, the lens settles at roughly 20-50/sec shutter speed when turned on. Only a high ISO can bring the thing up to speed. (A) mode. Also many of the photos are a little distorted and not flattering. I took several shots of women in bikinis.. Unlike the 14-150 which compresses... this one seems to shrink, and distort funny. I think its good for landscapes, perhaps. But not people. And especially if the people are moving. Just my 2 cents.

Thanks, would you say this lens on an em5 ii would feel unbalanced /awkward to handle?

Sorry for the offtopic but that's Turin!! Was it vacation or you live there?

Has anyone tested this on the Panasonic G85? I'm thinking of getting it as an "all purpose" lens along with some primes.

The holy grail of travel lenses..... it really doesn't get any better than this. Well, unless someone made a 24-150mm f/4 full frame lens.... (closest is the Tamron 35-150mm f/2.8-4)

0:18 how you do a 4s shot hand held. Really? wow..

Have you tried this lens lately on a Panasonic body that has in-body IS like the GH5 or G85??? If so, how well does it work in that scenario? I assume you have to use one or the other in that setup....either the IS in the lens or the IS in the Panasonic body. Do you have to turn off the in-body IS on a Panasonic or does it just know an Olympus lens is connected and won't try to use in-body IS unless the IS switch on the lens is off? I guess I'll find out soon enough because I just bought one to go with my GH5! ;-) Curious if anyone has any experience with this setup though.

Nice review. Just want to ask, is it true that if you use an Olympus lens on a Panasonic camera, Panasonic's depth from defocus (DFD) autofocus feature will not work?

Hello.. Is this lens is suitable for omd em10 mark ii.... thank you 🤗

*IMPORTANT QUESTION* I have the Panasonic G9 body, but like the build quality of Olympus lenses. I wanted to ask if the IS build into the Olympus lenses will be compatible with the IBIS in the Panasonic body? Resulting in 6.5 stabilization stops. Also, will i be able to program the function button on the Olympus lens when mounted on the Panasonic Body? Thank you

What a lovely reviewer... lens, I meant :D

Do you prefer this to the 40-150mm Pro?

Does the lens IS work in tandem with the E-M1 Mk1 body IS?

The lens IS can be active on a panasonic body ? thank you.

Not parafocal ?

How can you have a weather-sealed lens that extends while zooming??? Crazy proposition!!

Is f stop usable indoors?

How can I use this lens with Sony a6000

I can use it with : Hybride Olympus OM-D E-M1 Mark II??????????

Will that lens work in full Auto Mode on the JVC Gy Ls 300?

Its huge but i guess some people don't mind that

anyone use this lens with panny body? hows AF and will IS work as a stand alone is?

what mount is that?

You have no accent Great video I wish Olympus would make a GH5s with image stabilization

Any degradation of IQ @ 100mm?

Nice lens but too pricey for a F8 DOF... micro 4/3 lenses are getting too expensive and not getting any faster for a system really in need of fast aperture in my opinion!

I Don't know why you and or Olympus Considers this a F/4 Constant Aperture? because its Not, Just as you mention in This Video, Its IQ Quality going through all the Various F Stops Now consider its Price POINT Is Just flat Out Rediculous At this Price a Smarter Choice would be 12-40mm F28 if we keep jumping out and accepting these prices they are going to keep pushing them and higher onto US, Vary Nice Detailed Review done Vary Well THANK YOU Mathieu Gasquet

IMO gr8 lens at 299$ INSANE lens at 1299.... really f4? wat?

I just don't understand how an f/4 lens is a for pros. I'm not trying to be elitist, regardless of how I sound, but it just sounds like an oxymoron to me. I'm probably wrong. I think that's my only complaint though.

Visually, what this lens delivers, is disaster. Why? Because there ARE other values to a lens, not only sharpness, sharpness, sharpness, and only sharpness! What about micro-contrast? Colour saturation? Bandwidth? What about softness required for pleasing portraits and pleasing OoF? This lens is designed for noobs - made to be so sharp, that all objects within a frame are forced into appearing sharp. It is disastrous - such sharpness compresses up the space, brings far and near objects way too close, and when looking at the images, they are incredibly flat - like miniature versions of the real world. I look at landscapes with boats, trains, mountains, all taken with this lens, and if the focus point was at infinity, they all appear like miniature sets for stop motion animation projects! This lens must be used with >>utmost care
