    Looking for a good, slightly longer, macro prime that is relatively affordable and fairly compact. Just doing some web searches, the Tamron 90mm f2.5 looks like a pretty good option. Is there anything else I should be looking for? FL range would be in the 80-100mm region. Not too interested in 50mm macros. Using it on a GX7.

    UPDATE: Thanks for all the replies, but I pulled a 180 and ordered a Oly 60mm macro instead of going the manual route.

    I had an older Nikon 55mm macro which I bought a rainbowimaging adapter on eBay for $11.00 and could not be more thrilled with it. The lens cost me nothing! Images are terrific. lots of 'adaptable' deals can be found.

    I was skeptical having read reviews about loose adapters, but I had no issues at all...good fit on lens and body.

    I'm using it on my G5.

    i think I might just get the Olympus 60mm instead of the Sigma and a manual macro.

    I'm sure the Tamron is also 1:2. Somewhere here I've posted photos of a 1:4 Sigma 24/2.8, a 1:2 Tamron 90/2.5 and a 1:1 Elicar 55/2.8.

    Okay, I ordered it. :thumbup:

    I had the Sigma 60mm f2.8 in my cart for about a week and then I was looking at $100-200 macro primes and then just decided I was being silly when I could get a 60mm f2.8 WITH macro for not a whole lot more than the two combined. Found a used one in "Demo" grade at Adorama and bought it tonight. At 200g, it's going to be a lot lighter than a metal brick with an adapter, too.

    Thanks for the feedback, anyway.

    My Sigma 90mm/2.8 MF macro is almost undoubtedly the sharpest lens that I own. Only goes to 1:2 natively, but it's an impressive performer.

    And it's very compact (52mm filter threads), and only weighs about 350g, to boot. Great lens.

    The Micro-Nikkor AI f4 105mm goes for a lot less than the faster versions but is pretty much as sharp at f4, and as sharp at 5.6 as the other manual micro-nikkors. It's a heavy old lens though... If 55mm is enough the 55mm 3.5 is a lovely little lens and cheap.

    How does the crop factor effect macro? Would it make a 1:2 full-frame lens 1:1 on m43?

    Hi,
    For a subject larger than the mu43 sensor, if you want to fit the whole subject on the sensor/frame, you're losing magnification.

    If the subject is smaller than the mu43 sensor, there is no change in magnification.

    Some companies claim otherwise because if you make the print the same size on both formats, you have more of a blow-up with a smaller sensor, but that is of questionable value esp. if the total resolution is the same on both sensors.

    Magnification is relative to sensor size, so yes. A subject the size of the m43 sensor would only fill 1/4 the area of a FF sensor and so you could say there was double the magnification ratio on 4/3. For the magnification to be the same you'd need a crop from a 64MP FF Sensor at 1:1 to be like a 16 MP m43 sensor at 1:1.

    guess?
    I have been continually pleased with the 4:3 Sigma 105mm 2.8 + adapter.

    how fast the af on micro 4/3? similar within 4second like zd 50-200 ed on m5/epl2 example?
