Micro MACRO advice/opinion please?

Hello Forum!
Last summer I took a break from purchasing lenses for my K30 with the start of the fall semester. (I was in a large and medium format film class.) At that time I was planning on buying a FA 100mm 2.8 macro next, and KEH had plenty of them with only a couple of D FA 100mm macros. Now that I'm focusing on lenses for my dslr again, KEH has plenty of D FAs and not one FA. Also, from what I can remember, the FAs cost a tad bit more.

So I would like to ask:
1: Is the "older" FA a better lens? (As it seems like people are buying them, while others are selling their "newer" D FAs)
2: Should I wait for a FA?
3: Is there someone with practical knowledge of both these lenses, who can enlighten me?

Thanks in advance!

Thought the only non-cosmetic difference was the coating and the weather resistance?

I think the F and FA are better than the original D FA. However, the newer D FA 100 WR is a fantastic overall macro lens. When it came out I forgot all about wanting the FA and got it instead.

As good as macro lenses are as a category, most have their weak points. The D FA 100 WR may not be the ultimate macro lens in any one category, but I can't find any weak points either.


In short, I'd skip the original D FA and hold out for either an F, FA, or D FA WR, with the latter being such a nice choice that you'll probably never look back.



Anyhow, I've given my advice but the most important part is to decide for yourself:

i had both the fa and the dfa non WR...the fa felt like a tank compared to the dfa....i had the dfa before the fa and bought the fa because i had read it had better picture quality...i was using it on the k5...the fa had a focus limiter which was a nice feature but not essential if you are doing manual focus...from a picture quality aspect i didn't see a difference so i sold my fa and kept the lighter dfa...my 2 cents for what it is worth..

I have the FA100 2.8 macro, and it's very well built, from what I can tell. Everything's internal, which seems more rugged - though that's perhaps just impression. I find it a good lens for chasing bees around the neighborhood.

If you're looking at doing some set piece macro, you'll also want a good tripod setup and investigate macro slider rail setup, so you can take multiple images and stack them.

Thanks for the replies!
Being I've finished my film classes and will be starting my first digital class 2/11/14, I'm trying to build a solid but versatile lens set. "My starting line up!" So all advice helps.

Honestly I hadn't given much thought to either the F or D FA WR. So I guess I could start saving for the D FA WR or just grab a F or FA if one becomes available before I reach the mark. There are a few of each on ebay, but I'm too nervous about buying ebay lenses. Especially from overseas!

Keep an eye on the marketplace here - it's the best place to buy. Enter the keyword 100mm and you'll see the macro lenses pop up via email. You can also enter 90mm since there are a couple nice 90mm macro lenses available, too. This way you're buying from owners who have presumably taken good care of the lenses. IIRC my FA100 was about $350 when I bought it about 4 yrs ago.

These macros are frequently found in the marketplace. You could also enter the term 'macro' but you'll get a lot of irrelevant results. You can also search the marketplace for current listings.

A few years ago I chose the FA 100mm over the D FA 100mm based on these reviews:

Thanks TER-OR!

I never heard of a Macro slider rail, so I better get to googling!

Thanks nater!

Reading those reviews helps a lot. Especially seeing the term "Plastic Fantastic!" It makes me cringe, being I have hands like bricks and break things easily, I should probably stick to metal brick like lenses. (FA) Honestly! So far, most SLRs/DSLRs feel sort of dinky to me, but I haven't made it to the PRO Cameras yet.


Thanks again everyone for your input, Chao!

The fantastic plastic 35mm is not the macro version.

I also have a Sigma 28mm f1.8 macro which is a really nice lens, but not an insect lens. Great close-up, though, and great for still lifes and objects.

Check Amazon for slider rail and be prepared to geek out. Also look for a remote, since that's probably the easiest way to trigger and limit vibrations.

Took your advice and checked out Amazon, the slider rails seem reasonable enough that I can order one along with the lens and a macro ring Friday.

One more question please: How is the Tamron 90mm macro? (non DI) I've been seeing quite a few.

The Tamron 90 macros are well regarded. You can probably find some threads in the lens discussion area.
