What about T/S lenses? They have extreme decentering compared to these adapters, nothing like 10 micrometres, but rather 8-10 millimetres or more, i.e. ~ 1,000 as much.

In fact, I'd be surprised...

Oops! I believe I misunderstood the subject ;-)

What was I thinking?! I mean: If 10 microns is a problem, I dare not think what problems 11 millimetres will cause

Others have already mentioned it, but diffraction is your enemy. Then there's blur caused by temperature differences. If you shoot through an open window from a warm room and it's cold outside,...

I searched for the Tamrac 613 Super Pro 13 (made in USA) and found it on Amazon France. The seller was an independent dealer in England, who sent me a Tamrac 5613 Ultra Pro (made in China or...

... buy a Sony product one last time. I'm quite happy with the 18-55 mm, at least enough that I don't bother to use my A-Mount 16-80 mm (partly because it's much bigger, partly because I don't want...

Firstly, some macro lenses have internal focusing, which means their focal length is reduced for close focusing (their nominal focal length only applies at or close to infinity). Sony's 30 mm macro...

It's a lovely lens. Nice manual focus, exceptionally sharp ... and they're not lying about the boke, either. On the negative side, it's more than a little expensive, but you could get lucky an find...

... it does look like a very practical solution - if you sometimes use other types of cards than SD. However, it requires you to invest in one, two or three additional SD-modules right from the...

http://techmash.co.uk/2012/09/19/usb-connecting-multi-card-reader/ The cards will share the same bandwidth during transfer, so you may not gain a lot of time, although you won't waste so much time...

If anything, the more expensive filters ought to be an improvement. No, that would be stupid. I guess it's very much the same. I have Sony's, and it's all metal (and glass) - probably comes from...

The expensive solution is to get a drop-in filter for Minolta's 300 mm or 400 mm lenses - they are actually interchangeable with the ones for the 500 mm reflex, but metal instead of plastic. I have...

322RC2 Heavy Duty Grip Ball Head Not very easy to adjust precisely, but on the other hand very fast, so better for mono- than tripods. 410 Junior Geared Head Less notable for speed than precision,...

Newer cameras tend to be improvements over existing models - even when they're slightly lower-level. Technologies improve at a frantic pace, making almost any new product all but obsolete the...

Not much sense in reducing the size of the camera to a bare minimum, only to add a huge lens. If you want that, an A-mount adapter (or one for any other mount) will let you use those fast (and big)...

I mostly shoot in 16:9 for this purpose (although raw files retain the 4:3 option). Not so practical for portrait mode, but then again most of my pictures are  in landscape orientation. The TV is...

According to this site, it's a spare screw for the Quick Release plate that has gone missing: http://bogentripodparts.com/parts/head3047-03.htm You probably won't miss it, if there's already one in...

This would be my suggestion as well. I don't have the Zeiss 135 mm, though, so it may be a battle between the two. It certainly is incredibly sharp.

I thought no-one would figure it out ... but you did :-D

I wash them all the time, but still ...
