Summarits are on their second generation now. Older = 2.5, newer = 2.4. You need to google the differences. I think some got a slightly better close focus ability. For your first lens, I would make sure they focus down to 70cm, when it comes to 35 or 50. You may want to check the Zeiss Planar 2/50. Does not break the bank and you can sell it later probably for a similar price, if you buy used. No coding required.
