    Was thinking about getting the 35 f2, but after a bit of playing around with my zoom, the 15mm difference between my cheap and great 50mm 1.8 does not seem that much at all. maybe just a step or two back would yield the same view.

    however, many people seem to gush about the "secret" close focus ability of the 35 f2...

    Anybody care to elaborate on this or provide sample pictures to show its versatility?

    Thanks!

    you can focus closer than an inch with the 35/2 for greater than 1:1 magnification:

    click for the full picture. that's part of a 2-dollar bill, and I actually had to downsize it to 60% because the image was too big.

    WOW! i never understood the minimum focus distance stats on lenses, isn't the 35 f2 meant to have a MFD of 25cm or something?

    1inch..... hmmm, that really sounds interesting.....

    Yeah you just flip the lens backwards and take pictures with the lens reversed. They sell a reverse lens adaptor for this lens, but I don't have the adaptor so I held the lens backward by hand. It has greater magnification than dedicated macro lenses.

    Not without extension or supplemental lenses you can't.

    Using the 35mm f/2 AF-D Nikkor normally, you can focus to a magnification of 1:4.18. This is not quite in the macro range, but closer than just about any other non-marco lens can focus, and about the same as many "marco-zooms". Add the fact that this lens is fast and small, and it makes for an ideal normal lens for the DX format.

    You might prefer the 50 though, especially if you like to isolate parts of the whole. The 35mm is actually more than twice as wide (44° angle of view for the 35, but only 19° for the 50.) Here is how I came up with the 1:4.18 number:

    23.7mm sensor width/99mm field width = 1/4.18 magnification

    Chris, have you tried the same test with the lens reversed?

    No, reversed it won't meter on my digital camera. I have extension rings and bellows I ever need to shoot that close. Note that the 35mm does not have Close Focus Correction, so you will lose resolution when going closer than it's regular close focus position.

    All these with the 35/2. One of my favorite things about the lens is the ability to get right in and close. Not just the focusing, but the lens never gets in your way either because it's so small and light, and I can also hand hold it to ridiculously slow speeds on my D80 and still get a pretty high keeper ratio at 1/15s.

  12. The 35/2 close focus distance is about 10".
    The Sigma 30/1.4 is about 16"

    you guys really need to try the 35/2 reverse-mounted. then you're talking about REAL CLOSE.

    thanks nute and phil! Going to start getting some larger prints of those to decorate our house with. :smile:

    So how exactly do you reverse mount a lens? (newbie alert) What do you need? Any pictures (of the setup)?

    you simply use the lens from the opposite direction it is normally used. you can either hold the lens in front of the camera by hand, or use the special reverse lens mount made by nikon.

    Just about any lens can be reversed or extended to get macro level magnification. You can also couple a zoom and a prime for a variable macro effect.

    The nice thing about the 35mm f/2, is that it can focus closer than most other normal lenses, without anything extra and it retains full automatic function on your camera.

    SP77 - those are some amazing shots. Talk about capturing some great "baby" moments.

    I wasn't able to get close enough to my friend's kid with the 50/1.8
