Two aspheric elements actually. And these were ground and polished by hand—an extremely tedious, error-prone, and costly procedure. The original Noctilux 50 mm 1:1.2 was produced from 1966 to 1975 in...

When photographers who are used to standard and moderate wide-angles pick up a super-wide like 18 mm on 35-mm format or wider then all they produce mostly will be boring trash. Super-wide lenses do...

Bad idea. Don't do that. The Tri-Elmar-M 16-18-21 mm Asph's code will make the camera think you're using a 21 mm lens. Better use the code 51 (110011) when your 15 mm lens brings up the 35/135 mm...

Oh, yes ... sorry. After some googling, I found a remark in dpreview.com's X100 review stating that Fuji obviously had used a focal length of 35 mm rather than 23 mm in their calculations when they...

Seems to me you are confusing hyperfocal distance (Fuji's numbers) and depth-of-field at hyperfocal distance (DOF program's numbers).The latter always is from half the former to infinity.

So—what...

If you cut out a 24 × 24 mm square from the 35-mm-format frame and compare it to the 6×6 full frame—i. e. the largest 1:1 aspect ratio from each format—then a 50 mm lens on the 6×6 camera is...

No, most don't. In fact, most lenses designated 'apo' really are achromats only, not apochromats in the word's narrower sense, but with a lower-than-usual secondary spectrum (i. e. very low residual...

Oh yes, you're right. Forgot that one ... which is funny as the Macro-Elmar-M 90 mm 1:4 is a very interesting lens actually. Tiny, sharp, and will reach the highest magnification of all Leica M...

Only one—the Summarit-M 90 mm 1:2.5. [EDIT: No, it's two: the Summarit-M 90 mm 1:2.5 and the Macro-Elmar-M 90 mm 1:4 (thanks to Tim for the hint)]

Officially, there's another current 90 mm lens: the...

Basically, yes. You understood correctly. Except it's more like 1.45 m to 3.3 m ... provided you're using your 35 mm lens on a 35-mm-format camera. A 35 mm lens used on other formats, focussed to 2 m...

Good idea.



Huh!? That's just plain nonsense. It's a bad idea to avoid the lens you want just because some moron told you that he doesn't like the framelines. It's another bad idea to get two...

That's right. It means a normal-sighted person will see the framelines and rangerfinder patch at a virtual distance of 2 m.

While there might be a few good reasons to shoot JPEG only (as opposed to Raw or Raw+JPEG), just saving disk space isn't one of them. So don't do that!
