It's an oft said maxim " A poor workman blames his tools".
Flake said:How can I say this? Well partly because I know a professor involved in optics
Flake said:When someone demonstrably is talking nonsense I think it's quite easy! After all he's the one who's saying that the equipment is letting his photography down and it's not as good as it could be.c.d.embrey said:BTW have you ever seen any of his work? If not, how can you call him a poor workman.
Flake said:There are plenty of very good photographers around, a lot of making a success comes not from some kind of superior ability, but from luck, contacts, being in the right place, etc. etc.
Flake said:Just like many other professions. I wonder how many people could say hand on heart that Damien Hurst, or Tracey Emin are the absolute best living artists, and that there is no one in the UK / World as good?
Grendel said:This guy at least tried a more controlled comparision betw. the 85 lenses.
It is a harder lens to use, since it is manual focus only and exhibits focus shift at close focusing distances that needs to be compensated for.
Flake said:If he was that bothered about IQ why isn't he shooting medium format, or even large format film?
Flake said:Damien Hurst is a UK modern artist producing modern art on a commercial scale at very high prices, a lot of it is very controversial, such as a cow cut in half and preserved in formaldehyde.
Flake said:Composition? no need to bother with that when you can crop it when you get back, in fact the only thing a photographer needs to do is to press the shutter at the right time and make sure it's in focus, the back office can do the rest!
Flake said:Using the pop music analogy, it's like finding that a singer is miming on stage & using auto tune in the studio because they can't really sing, people still buy the albums and go to the live performances, and people believe that their idol is an 'awesome singer'
Flake said:Focus shift is where the point of focus changes on stepping down the aperture.

Ok thanks, I didn't think of that. It's weird though, since the light obtained by stepping down (in the pupil plane) is a subset of the wide open light. That must mean that the foci for the different pupil radii aren't aligned, blurring the image at wide open aperture.
