Is the leica macro elmar m 90mm f 4 good for macro photography?
Yes, I think it's a good choice for macro, with one caveat: it's a manual-focus lens with no stabilisation, so you'll be focusing by eye and holding steady. Close-up work is slow anyway, so that suits it. A tripod helps a lot at close range, where the smallest shake shows up.
It's a 90mm on full frame, a focal length that gives you room to work at close distances without crowding your subject. It's also collapsible and light, so it won't weigh down a bag you're carrying all day. It fits any Leica M body, and I'd start with these:
- Leica M10, a solid, straightforward pairing
- Leica M11, if you want the newest body in the range
- Leica M (Typ 240), a good option if you're buying used
