90 Macro Elmar

Hi guys, I was looking for a small, compact 90mm to use mainly for travel. I previously owned the 90mm Elmarit-M, which I can only speak highly of; now I’m wondering whether it might make sense to invest a bit more in the Macro-Elmar.

What I don’t fully understand is how the close-focus system works. To be clear, I’m not interested in macro photography at all, though having that extra close-focus capability for portraits could be a nice bonus.

Correct me if I’m wrong: the lens has to be mounted in reverse on an adapter in order to shorten the minimum focusing distance; without the adapter, it’s essentially a super-sharp 90mm f/4 whose main advantage over the Elmarit is its compact size?

You are correct that, mounted directly onto the camera without the macro adapter, the M 90 Macro Elmar is "a super-sharp 90mm f/4." It is a fantastic travel lens.

The close focus works first of all by adding a space of some 10mm to start off the focus from 70cm down (ring at infinity) to much less than 40cm (the distance ring turned alle the way out). Why the lens in put 'upside down' is that there is an extra mechanism to engage with the rangefinder for the CF working. This means that on close distance I can use the RF! Much better than a 'modern' CF lens that only can be used with an EVF.

And yes the lens is super sharp/high resolution and takes great candid shots also because the focussing is so quick and precise.

There are two different M macro adapters. The original one is rangefinder-coupled with goggles as described by @Alberti above. The newer one is a variable length extension tube without rangefinder coupling. It can be used with some other M lenses as well and requires LCD/EVF for framing and focusing. The lens itself is collapsible and always mounted with the front element facing forward.
