Other's have commented (and my tests have confirmed) that my 1D4 and 5D2 cannot actually see light from a cone that's faster than f/1.6.

This is incorrect. There is a loss of light due to the sensor but there is a definitively different blur with f/1.2 vs f/1.4 and f/1.6.

Seriously . . . what EVERYONE else said.

Roger can sum it up in two short paragraphs:

But it's only half a stop better if the camera detects the light. Other's have commented (and my tests have confirmed) that my 1D4 and 5D2 cannot actually see light from a cone that's faster than f/1.6. This does vary from lens to lens - some modern lenses are telecentric so that all the light gets to the photodiode. However, the 50/1.0 comes from the film era and is not telecentric. Ergo, NO fast aperture, NO narrow DoF and NO benefit.

I don't know... seemed like there were some bits of usefulness in the write-up.

That said, I've only seen this lens in pictures and auction listings. I've never used one or even touched one. I haven't looked into renting one, but that could be neat.

I took the sample images as examples of everyday uses for this lens, for those with the means to afford it. I wasn't expecting art-quality images with weeks, months or years of composition time or thought.

And for what they were, the images looked good here on my end. I'm not downloading the full res samples, though.

Ah - another insightful rant from Clueless Kenny, the uber math whiz.
I'm quite curious how f/1.0 can be 1/2 to 2/3 stop faster than f/1.2... what causes it to vary? Phase of the moon?


The problem is rounding. "f/1.2" doesn't mean 1.200000... It may be anywhere from 1.15 to 1.25 (or even 1.29 if the manufacturer is lax) "rounded to the nearest decimal place".

f/1.0 plus 1/2 stop is f/1.18920711500272... f/1.0 plus 2/3 stop is f/1.25992104989487... Both would be displayed as f/1.2 by your camera.

I don't know, I saw those comments about perfect focus and figured the whole thing was a joke.


From his site:

Quote
I occasionally weave fiction and satire into my stories to keep them interesting. I love a good hoax. Read The Museum of Hoaxes, or see their site. A hoax, like some of the things I do on this website, is done as a goof simply for the heck of it by overactive minds as a practical joke. Even Ansel Adams kidded around when he was just a pup in the 1920s by selling his photos as "Parmelian Prints." I have the energy and sense of humor of a three-year old, so remember, this is a personal website, and never presented as fact. I enjoy making things up for fun, as does The Onion, and I publish them here — even on this page.


BTW, for any of you who criticize him (and I often find myself in that group), his site has an Alexa ranking in the top 5000 for US and top 8000 globally. He could choose to monetize that with Google ads (and make A LOT of money), but he doesn't. Yes, he posts affiliate links and solicits contributions, but no one is forced to give a donation or click on a link. Just saying...

When people see you arguing with an idiot on the internet, all they see is two idiots arguing.

Nobody ever criticized him for not being able to attract traffic to his site.

You (conveniently) took part of my post out of context. If you care to comment, please do so about the point I made (I'll make it easy for you - they're the two sentences that follow the one you decided to quote, especially the first one), not the supporting data.

Then consider how other photo sites, like this one, are totally monetized and use affiliate links as well.

And you took my comment out of context. How much traffic he attracts and in what way he profits from it or not (your next 2 sentences) is rarely the reason he is criticized even though he is often ridiculed for mentioning his "ever growing family". The criticism is for his trollish behavior, his "reviews" of equipment he never touched, his incorrect statements (not opinions), his hypocrisy (sharpness and cameras do no matter, BTW, have you seen how crazy sharp my Leica is? Look at my 6"x7" shots form Italy).

BTW, this particular review is very good but he still does not miss the opportunity to be dishonest. He calls well downsized images "full resolution". He just cannot help it.

It kinda makes you want that lens, doesn´t it ... Maybe I should have spent $4k on this one instead of the Otus (which I haven´t received yet) ... Maybe one of the expected 2014 lenses from Canon is a version II ...

"the" other $4000 50mm lens makes it sound like it's the only one on the block.  Leica noctilux 50/1 sells for roughly the same amount of money, used.    The new Leica noctilux 50/0.95 costs substantially more.
