I am thinking of getting a macro lens. Technically, it seems, I already have one, a Sigma DC 18-50mm, but it doesn't feel like it when I try to take close ups. I have an Olympus E-3, Olympus 1.4xTeleconverter EC-14 (and fwiw, a Olympus Zuiko Digital 50-200mm). Maybe I just don't know how to use the lens I have correctly? Or if buying a lens is i order, what can you recommend?

This raises another question. If Olympus is getting out of, or at least de-emphasizing, DLSR, should I, instead of buying another Olympus lens, buy another brand of body? Will my current lenses work on other brands of body?

Olympus are concentrating on m4/3. While there are still 4/3 lenses available, they are mostly on online auction sites.

Their lens lineup has 2 macro lenses. The 35mm f/3.5 and the 50mm f/2.0. The 50mm is the better, more expensive one.

As for the Sigma 18-50mm, I haven't heard of it before. Are you able to find a link about it so I can properly compare and answer?

The link in your answer doesn't state it is a Macro lens. Most macro lenses are a fixed focal length, also.

In regards to getting rid of the 4/3 glass, there is no need. Olympus have an adaptor for m4/3 to 4/3. The MMF2 and the MMF3. The MMF3 is meant to be waterproof but there is no speed difference with these.

What makes the difference is the body. That adaptor will work on any m4/3 body. Of course designed for Olympus bodies, they will still work with Panasonic.

The OM-D, E-M1 was released as an alternate to the DSLR and the focussing speeds with 4/3 glass is almost on par with the E-3/5. Certainly with the E-620 and faster than the 4xx/5xx series.

That sigma is actually designed for the APS-C format (think specifically for Nikon's DX format, not Canon's APS-C format), so yes, it will work.

I guess their isn't really an answer for "Keep lens, buy body" or "Buy new lens only" as that will come down to personal preference. Research, take a look around. Try out the E-M1 body and Nikon's DX bodies and see if you can get your hands on the 50mm f/2.0.

But, both options are available.

  • So what's the difference between a fixed 50mm lens and an 18-50mm lens positioned at 50?

  • Nothing, really. But any lens at 50mm compared to another can be different because a certain lens can hold different characteristics and have different minimum/maximum apertures. But the difference between a Macro 50mm and a standard 50mm is the focussing distance. Macro lenses have a much closer focusing distance and are generally a fixed focal length (doesn't zoom). That lens you have, technically is not a Macro lens.

  • Oh, the difference is the focussing distance, that's why I would by a fixed 50mm macro lens.

  • Macro lenses can come in varying focal lengths, they just generally aren't zooms. 50mm and 35mm are the only 4/3 macro lenses. Macro also just means a 1:1 reproduction image size. So, if you took a photo of a 24mmx36mm box on a 135 format camera, that box would fill the frame. The length could mean you are 1m away from it. But in general terms, a macro lens has close focussing distances and also aren't zooms.
