It's a pity that Zeiss doesn't offer fixed wide and super wide Distagon lenses with the Sony attach. There is only the Vario-Sonnar T* 2.8/16-35 ZA with a weight of 900g. I would like to use the manual focus Distagon lenses on the Alpha 850. Otherwise I have to wait for the upcoming Canon 5D MK3.
A person in Europe, linked to the pre-release field testing of Sony lenses (also a top-notch photographer), indicated that there are around 8-10 Sony lenses on the way in 2010, including Zeiss primes and also a 500mm f/4G SSM. About the 500mm, his initial indication was that it would be an f/4.5 but he later confirmed that it would be an f/4.PS: In all of the prior Sony releases, he has been dead accurate with his predictions. One of the possibilities for 2010, is a CZ 18mm.
Any idea if there would be a 35mm prime (f2 of 2. ? Really wish sony would announce which lenses are going to be released so I could make some decisions on brand
http://www.mhohner.de/sony-minolta/lenses.php?lg=eScroll down to the Minolta 35/1.4G and 35/2.0. Again, same lens just not currently produced by Sony with their name on it.35mm is a favorite of mine as well for photographing people and scenery.http://www.dyxum.com/lenses/detail.asp?IDLens=14This has some images of it on an A900 - so it does quite well with the new cameras as you can see. I like how it looks identical other than the aperture's changing the field of focus(though 1.4 is a bit soft, 2.0 is perfect). http://www.dyxum.com/lenses/detail.asp?IDLens=13I especially like the white cat. It's exactly the same breed and color as mine that recently passed away(wish I had a photo of her like that...) - obviously get the newer model, though, as it's better and has more features - but the optics are identical.http://www.dyxum.com/lenses/detail.asp?IDLens=70Here's the 2.0 - IMO, I don't see a huge difference. It's clean at 2.0 and appears to be essentially the 1.4 if you didn't have the last stop as an option. For $300 or so, used, this is a steal.http://www.dyxum.com/dforum/topic11527.html - more images. Again, the older lens here - same optics as the new.http://www.dyxum.com/lenses/detail.asp?IDLens=2Here's another one I hope to own some day. I never have used a 50mm - the aspect ratio just looks "off" to me. I like 28, 35, and 85 a bit more as options. Three extra compact prime lenses also hardly take up any space.(my fourth is a nice macro zoom lens for when I absolutely have to have that type of shot.
Yeah, finding these used can be a bit of a pain at times. The zeiss zoom, though, is a very good lens. One just sold on Ebay for $1200 used, which while expensive, probably replaces three lenses right there - the 28, 35, and 50mm.
I've played around with both and it's not even close to the Zeiss. The problem is that like most zooms, the last stop is essentially there for looks. 4.0 is where it is somewhat sharp again, and if the goal is to be able to use the full range to replace primes, it's just not any better in real use than a typical budget zoom(ie - nice for a trip but not for real work) The Zeiss, otoh, is a fantastic lens that is usable at 2.8 throughout its entire range, which almost makes it a replacement for a set of primes(all but the most picky wouldn't likely notice since most primes have to be used at 2.8 to get sharp again).
