Holy Depth of Field, Batman (aka, what's your fastest lens?)

Mine, as you can see, is a littleeee more complex than that. And I can use aperture control. I'll be updating that page soon to include my newer Sigma 24-70mm EX DG Macro in the reverse mount. I hope I don't have to rewire it, I didn't design it for such a massive lens (I already got the step down rings from 82mm filter threads to 58mm}

Holy Cow! Erm, yes, I would say that your approach is very much more complex than simply connecting two lenses together with a reversing adapter ring. Whooooo!

VERY interesting!

(I think I'll stick to just using my macro lenses in the way in which they were designed....)

Only slightly fun, everything I've read about f1.2 and f1.0 lenses (barring the Canon 85mm f1.2) has said that they are not very sharp or useable, and that the money should be saved and just buy a 1.4.

Well, since I've already got the f/1.4, this would just be going a bit further.... And, yes, one would need to be somewhat careful and selective when using any f/1.2 or f/1.0 lens because of the depth-of-field issues and the focusing issues.

No I mean their optical qualities not being so good. Besides how many stops is 1.2 or 1.0 over 1.4?
 
Canon 50mm f/1.8 for me, too.

Great composition and tones, but more DOF would have made it perfect. This is kinda going against the stream in this thread, but what the hell!

Thanks for the comment! I agree about slightly more DOF to get the whole leaf in focus. The 2.5" LCD on the new 30D might have helped... (for reviewing)
 
I've been wanting a fast prime for some time now, and because of this thread restirring my need to have one (lol) I just ordered a Nikkor 50mm f/1.4D from bhphoto.

I'll have it for the weekend to test it out, and I'll be posting some pics soon :D :D :D :D

Tamron 28-75 f2.0?? improbable. That would be awesome though, it would be the fastest normal zoom ever.

Your old/new fastest lens is also my fastest lens, sitting unused somewhere. I also have a 35 mm f/2 wide angle which was quite nice in its time, and a 135 f/2.8.

I think these old F series lenses won't fit properly onto the newer bodies with all the AF and AE stuff that's been added, at least without modification if that's possible. Anyone know?

I apologize if this has been anwered earlier in the thread. Nikon AI lenses (the old kind with auto indexing, ie: those that you can read the aperture in your view finder) work with only a limited number of digital bodies, the cheapest being the D200. The lenses will work (mount) on all Nikon bodies but you will not be able to use the exposure meter (get a light reading) with a D50/70/100. In all cases they will always be manual focus. I also have a Nikkor 50 mm 1.4 but someone in another thread had mentioned having a 1.2 :rolleyes: That must be fast! I have heard that there might be a cheaper version of the D200 (rumored) so I am hoping I will be able to get a digital body that will work with my old Nikkor lenses since I have loads. However, to this day, I think film is better for low light situations and my F3 with a Coolpix V scanner will beat any digital pro camera, provided you know how to use it ;)
 
Here's a shot of one of my fam's cats with my 50mm 1.8 - has a pretty narrow DOF. Love that lens!

It maybe hard to tell in the small jpg though.

couldn't find a reversing ring locally (or in austin) and i needed it for this weekend...o well

i might not end up ordering it, cause i only needed it briefly (for photographing some coins for a science project)

boyd's camera has a used 49mm reversing ring i think. any way to make this work? :eek:

Very-wide aperture lenses often exhibit more obvious vignetting (edge darkening) because of the optical effect of light rays having to travel further to the focal plane the further away they are from the optical axis. Also, their minimum aperture is usually less wide (typically only stopping down to f16) since smaller apertures often introduce diffraction (seen as a softening and drop in image contrast). That's maybe what you meant about wide-barrel lenses having lower optical qualities.

That said, at 'normal' apertures (from maybe f2.8 to about f11) the quality of wide-barrel lenses is just about as good as from anything else.

f1.2 is half a stop wider than f1.4. f1.0 is a stop wider than f1.4. FYI f-numbers increase/decrease by a factor of the square-root of 2 (with a little rounding-up to keep things sane).

I used to have a Leica M4-P with a Noctilux 50mm f1.0. It weighed an absolute ton and focussing at f1.0 was like Russian roulette (lens theory tells you that at f1.0 a subject 6ft away gives you depth-of-field of a little over an inch!). Vignetting at full-bore dropped the image edges down by (at a guess) a couple of stops. However, stop down to f5.6/f6.7 and the image was awesome. That lens was a beauty.

(time to take off the rose-tinted specs....;) )
 
WOW! I am very impressed with the Nikkor 1.4D.

I just opened it out of the box less than an hour ago, and have had limited time to use it, but I'm happy so far :D

Here's a snap from outback.

Oops! Typo. Should be 2.8...

Schweet. :D
 
My lens with the greatest depth of field would be my 70-200 f2.8 all the way through.
