...It would be interesting to know what percentage of forum member\'s shots are taken with focal lengths wider than 35mm. I like to have a 21mm sitting at the bottom of my bag, but only pull it out 5% of the time.

A poll on RF Forum showed that for 90% of people the most used focal lengths on 35mm format were from 35mm and up.

Which is your most used focal length on Full Format 35mm cameras


A while ago I looked at my M9 Lightroom stats and I think 21mm was around 1/3 of the total. I would estimate 2/3 of my rangefinder images are wider than 35/50mm.

Interesting points Ron. Actually, the 28mm FL is the one I am looking to fill at the moment. I don\'t want to spring for the 28cron and was considering the ZM28 as the best RF option at the moment. I like to keep my kit small and would rather not go with an SLR lens. This would be primarily a landscape lens for me to edge/corner performance would be very important. Any other RF choices? Konica Hexanon?


Did you sell your Elmarit? I don\'t know if I still have the test images I did with the CV28/2 and ZM28... From memory, the CV lagged the ZM at the edges by probably a couple stops, was a bit lower contrast and had focus shift... there was still edge improvement at f/11. The ZM is centrally very sharp with high micro contrast, but you\'ll probably have to stop it down to f/8 for the edges. The MTF at 5.6 still looks pretty wanting. I think a friend has one and maybe I can borrow it at some point for some additional test photos.

As for other 28mm RF options... I guess there are the older Leica Elmarits. No idea how they perform, but I suspect they\'re technically not as good as the ASPHs. Haven\'t tried or researched the Konica. Wasn\'t there also one from Minolta for the CL? Also the vintage Canon and Nikons... and from MS Optical in Japan... But in terms of new from the major brands, there are only 4 that I know of.


The 28 Elmarit Asph is a very sharp and has excellent contrast. I am sorry that I sold it, to upgrade to the 28 Cron, as it is so light and ergonomic. This would be a great lens to try on the A7\'s!
