Luka, love these, especially #2 and second to last!
Adam, @f/5.6 and slower, you're not going to see much, if any difference between the 21 SEM and ZM21/2.8. The 21 SEM wide open is a better lens - much flatter plane of focus and already extremely sharp across the frame. The ZM21/2.8 has some field curvature and as a result, wide open sharpness is best in the central area with flat planes (walls, etc.). IMO, the benefit of the SEM is you don't have to think about what aperture you're shooting at. It's just sharp. Always. Therefore, for technically demanding applications, it's an excellent lens. 6-bit coding is also nice to have. With the ZM I found the hand coding sometimes wouldn't read due to strong, direct sunlight hitting the lens/camera mount interface in that area. And the ZM really does need to be coded to take advantage of edge color shift corrections (coded as the 21/2.8 non-ASPH), or you'll have to fix it later with Cornerfix, etc. You can probably get better coding reliability by having the flange engraved.
My 4-way 21mm M-mount shootout includes the ZM and SEM. Best bang for the buck is the Voigtlander 21/1.8, blending the speed of the Lux with stopped down performance of the ZM and SEM, though with lower contrast/micro contrast. Tradeoff is it's a fairly large lens.
I've read that with the M240, many wide lenses are performing even better into the corners (for sharpness), therefore my results might not be exactly what you'll get with the M. It would be interesting to see some technical comparisons of a lens like the 21 SEM on both cameras......Show more →
Ron,
Thanks for all of this. I think I've read your link before, but I did give it another go this morning.
I take it nobody has played with the 18 SEM?
I'm actually REALLY considering the 21 LUX, but that's nudging into Noctilux or 50 APO territory, and I shoot 50mm 90% of the time with Leica, so if money's being spent, it should be spent on a 50mm. I'm actually considering one of the SEM lenses, or the 21 ZM, just wondering if it's worth double the price to pickup an SEM over the ZM, something only I can answer at the end of the day I guess..
My 28cron serves me well, and I like it, but I can't help but think that I should have stuck with the 28 elmarit-asph, as I really do miss the way the lens rendered. I'm thinking, and correct me if I'm wrong, but the 28 cron is like the 21 LUX, how the 28 elmarit-asph is to the 21 SEM? If this is a fair assessment, then I might just save a boatload of money, buy the 21 SEM, and call it a day.
I only really need the lens for my honeymoon in italy, whenever that happens.. Since I've been busy with work, and haven't booked the trip. But I'll probably not sell it off afterwards.
