No joy on the focus confirmation, but the SSS seems to be working ... the little bar graph appears in the viewfinder and is active. Of the two, SSS is what I'd rather have anyway ... the finder is pretty bright and easy to focus.I thought alt glass (like the new leitax R-Sony kits - see website) needed to be chipped to engage focus confirm and SSS?
I thought it was easy as well but just curious if you are using the stock focusing screen or if you swapped for one of the others?... the finder is pretty bright and easy to focus.
Wonder how SSS works being lens FL dependant? Less or more correction?Ok so, no chip:
- SSS works, camera has no idea of FL, so probably defaults to 50mm (just a guess).
- No FC
- No AE (that sucks)
Of course you can hit up leitax's recommended chip vendor and fit the eprom to your Hassy/M645, etc adapter and be good to go. Alt zooms would be an issue with SSS, but I guess just have encoded to longest FL and fastest Ap as is done with chipped adapters on EoS..
Yeah, I'd like to see info on that myself.It seems that SSS works without a chip, but it works better with a chip that gives the camera the correct focal length..granted I haven't a seen anything too scientific that tests this.
Stock one.I thought it was easy as well but just curious if you are using the stock focusing screen or if you swapped for one of the others?
Focus Compensation?What's "FC" stand for?
I think you are dead on the money Guy. I've done a ton of adapting on various cameras over the years in search of some Holy Grail, and in most cases it was due to the poor performance of some of the manufacture's glass ... or the need for some special application. However, it was usually a PITA to use.If I may go back here for a second. I think and I like the Mamiya glass very much but I only see real value here given the Zeiss lenses are being used for the Sony and from all that I have seen very nicely to boot. That using Mamiya or alternative lenses on the A900 maybe a waste except for a few lenses that may just bring a certain look to the table that the Zeiss does not have or something relatively inexpensive that maybe worth the effort.
I will name a few that might be fun to try that are different . Mamiya has a old manual fisheye a 24mm I believe that is very nice. The 50mm shift lens for obvious reasons, the 200 2.8 apo is killer sharp and 600 dollars and the 80 1.9 is a fun cheap lens. there maybe a few more but they are the obvious ones. A Hassy 110 f2 is also a sweetie but after that not sure any wide would be better than the 16-35 of Sigma 12-24 and anything mid range why bother but the long end like the 200 apo and the Hassy might be great on it. I guess i say this because i came from a long history of bolting lenses on canon before it was such a popular thing to do and it's a PITA most of the time but the main reason was I was not happy with the Canon glass and i just don't see that in these Zeiss lenses so i would be careful you going off the deep end on this idea unless it brings you something different to your toolbox. Okay you can ignore the advice but i thought I would just toss it in the bowl and let it stir around.
FC = Focus Confirmation.
I add FC chips on all my alt glass for my 1ds3 because it helps the AE be more correct with that particular alt lens by using the focal length and aperture info and thus I don't have to add as much AE compensation as I would without the chip. It helps with adding the lens info to the exif for each shot which I really need to keep track of which alt lens I used. And now the latest chips have added the micro lens adjust feature for canon mount. Sounds like you need a chip for the A900 to be able to have Aperture Priority mode to work which is very important, no?
