Following a discussion in another thread I became interested in finding out how good people are at differentiating between the lenses of two different lens manufacturers.

We've had threads where people had to match images to specific lenses and the results have been varying. This is a far more simple test - is there objectively a "Zeiss" or a "Canon" or a "Leica" rendering style - i.e can you associate a certain look with a lens manufacturer? So this is not about which lens is better or which you like more. It's just to see if people can consistently tell the two brands apart.

I'm going to post six pairs of images. For each pair one is an image shot with a Canon lens and one with a Zeiss lens. The challange is to for each pair guess which one is the Canon and which one is the Zeiss. The two shots that form a pair have been shot at the same aperture and with the same nominal focal length (there is some variation in actual FL per lens). A total of 9 different lenses - four Canons and five Zeiss lenses were used. The images have been processed identically. The order of the images has been generated by a random generator.

I'll give the answers in two days or after 20-30 people have guessed.

To compare the images, open the pairs in separate browser tabs and flip between them.

So...

Canon or Zeiss?

I'll bite!

A-1 = Zeiss / A-2 = Canon
B-1 = Canon / B-2 = Zeiss
C-1 = Canon / C-2 = Zeiss
D-1 = Canon / D-2 = Zeiss
E-1 = Canon / E-2 = Zeiss
F-1 = Canon / F-2 = Zeiss

Zeiss- A-1, b-2, c-2, d-1, e-2, f-1

The paranoid part of my brain is telling me you shot all of these with only 1 brand of lens so you can prove to us that lenses don't have certain "looks" lol..but I guessed anyways xD

I like A2 better, I like B2 better because B1 has too much vignetting, C1 is better, I like the higher contrast in D1, but do not like the vignetting, I like E2 better, and finally I like F1 better because of the detail in the rocks on the right. I do not want to guess which is which, but based on my answers, do I lean toward canon or Zeiss:)

Lens selection from an internet image is an exercise in futility, but I'll play...canon is #1-image 1, #2-1, #3-1, #4-2, #5-1, #6-2.
But a little PP would make them indistinguishable.

Gotta agree with this "The paranoid part of my brain is telling me you shot all of these with only 1 brand of lens so you can prove to us that lenses don't have certain "looks" lol"

Hehe, no, it's not the case. Nine different lenses were used - five Zeiss and four Canon lenses.

Ah, but the question is not which you like, but if you think you can identify the differences consistently. Informed or uninformed guesses will do ;)

I tend to be terrible at these hence my opinion of "who care what you have, the photo is what counts"

A1 Canon A2 Zeiss
B1 Zeiss B2 Canon
C1 Zeiss C2 Canon
D1 Zeiss D2 Canon
E1 Canon E2 Zeiss
F1 Canon F2 Zeiss

No, I cannot identify the brands, and will make no claim that I can. But I do know what I do like when a photo is rendered. I have two Zeiss Lenses-both are considered mediocre Zeiss by conventional wisdom-a 35mm F 2.8 Distagon, and a 135mm F 2.8 C/Y Sonnar. I picked them up just to fill a couple of FL holes, at a steal of a price (about $100.00 each). They perform well enough for my purposes:)

I'd like to see at least 50 people vote so we can do some statistical analysis about which images were judged/misjudged most, and which were easiest to tell.

50 would definitely be nice, but I'll settle for 25. It will give a margin of error of about 20% with 95% confidence. I'm primarily interested in the statistics - i.e if we can get a statistically significant answer to if people at the POTN level of knowledge (i.e a variety of photographers) can tell them apart consistently.

If the images had been posted here, I'd have given it a go, but I can't be bothered to wade through a load of links. Sorry.

The links are for your benefit. It's no good looking at images one after the other - the brain just interpolates between them. To really see the difference you have to flip between them. You can simply open each link in a new tab and then flip between the tabs.

In all my years here, I've never understood why people post just to complain.:rolleyes:

Luka, I think this is a fun "test". In any case, I'm interested in what lenses you used & how this poll turns out. I wonder how many, self included, are even close.

I like the browser tab flip method, and I hope more people who post similar comparisons adopt using it:)
