100 mm macro

I have a Kr and I am considering upgrading my macro lens.

I have an older SMC 100 3.5 FA

I am considering getting either:

DFA 100mm 2.8

Or the older SMC F 100 2.8

I shoot close up stills and my old lens seems to work fine. What am going to gain by upgrading?

I have a close up screw in lens for my old lens so I have a lot choices. It does auto focus and I can use either in manual or auto.

The FA100/3.5 (Cosina) is pretty good. I decided it was worth it to go all the way to the DFA100WR macro. Anything in-between I sold. I still have the Cosina as well.

The F or FA100/2.8 macros are the only other lenses I would have considered instead. They will still be an improvement. Most of the time I slightly prefer the F glass over the FA, but not always.


But get the DFA 100/2.8 WR if you can afford it. IMO it's the best overall macro available for K-mount. Other macros may slightly beat it in one area or another, but it's really strong in every area and has no apparent weak spots.


You're gaining better IQ, a faster aperture, and obviously WR. You don't have to deal with front adapter to get 1:1 macro. And it's good at "normal" (portrait) distances out to infinity, where many macros are weak. And the rounded aperture blades on the WR version seem to really help.


Don't bother with the non-WR DFA 100 macro. For some reason, the images from it just aren't as good. If the WR version isn't an option, you're better off with the F or FA 100/2.8.

Are you looking to go 1:!?

You wont benefit much from the larger aperture if you're shooting flies in a vice, the DOF at 2.8 will be too thin in my experience. Unless of course you are shooting size 22 or smaller mayfly patterns :P

The shot below is A 100mm f4.0 with manual extension tube #3 at f8 I believe.

If budget is your concern,you can try the Sigma 105mm macro,the non-DG version. I got mine for less than $250 and Im really impressed by what it offers me.

A sample picture from the lens. More in my set.
