The Techart TA-GA3 adapter sells for about $250 at or (affiliate links).

Manual focusing with this method works better than I would have expected but can be a bit fiddly at long distances. I changed to manual focusing which is realized with a small wheel at the 2 o’clock position. I it found unusable, but then that performance level of AF is what drove me to manual focus in the first place, and some people seem to use it without major complaints. It also fails when it is a bit darker in situations where native lenses still work reasonably well. Reliability was mediocre and not near the same level as the native lenses. The screw driven AF is rather loud and while it tracks small changes in focusing distances well it is quite slow to realize larger changes in focusing distance. The AF experience is certainly not as smooth as with native lenses. The Techart TA-GA3 adapter is very interesting because you can use AF with newer Sony E-mount cameras! AF with the Sony a7, a7r and a7s is unusable (very slow and unreliable) but with the newer cameras it works quite okay most of the time and gives you all the quickness and accuracy of a screw-drive AF lens on a dslr from 2005 (if you have used one of these you will know what I mean).

I have heard good things about the Metabones and Fotodiox Pro adapters but I haven’t used them personally. Focus is a little rough and in the wrong (Nikon/Pentax) direction, but perfectly serviceable. I own the Kipon one (or possibly a cheap knockoff since I got it second hand for ~$30) and it works fine on all the lenses but the 90mm (which I had trouble focusing accurately at near distances with). They range in price (affiliate link) from $25 to $140.
Mechanical adapters are available for EOS M, Fuji X, M43 and Sony E-mount. There are two kinds of adapters, purely mechanical and electronic adapters. The other problem is that the lenses do not have a focusing ring, just AF coupling so the adapter must provide some means to focus the lens. The advantage of this short flange focal distance is that adapters for mirrorless systems are only about 11mm thick. Both are AF rangefinder cameras.Īdapting Contax G lenses to modern digital cameras comes with two challenges. Since the Contax G cameras have a rather short flange focal distance of just 29mm you cannot adapt them to DSLRs.
The Carl Zeiss Contax G lens line was originally developed in the mid 90’s for the Contax G1 and it’s successor the Contax G2. It comes in two colors: Titanium and black but black is much rarer (and more expensive). More information in Zeiss’ official data sheet. Sample Images Sony A7 | Carl Zeiss Contax G 28mm f/2.8 Biogon | f/2.8 Sony A7 | Carl Zeiss Contax G 28mm f/2.8 Biogon | f/8 Sony A7 | Carl Zeiss Contax G 28mm f/2.8 Biogon | f/11 Bonus: The Contax G 28mm Biogon is both Phillip and my favorite lens on aps-c cameras, so I will also add a second installment later reviewing the lens for aps-c provocatively titled How the A6000 + Contax G 28/2.8 is better than an RX1.
Check captions on sample pictures to see what camera was used. Unless otherwise noted, all of the tests in this review were performed on a Sony A7RII with a reversed 1.5m PCX filter on the lens (Thanks again to Nehemiah for lending me the A7RII). I have shot this lens for years on the Sony A7 and more recently with a PCX filter and then on a Kolari UT modded A7. Can a simple filter make the lens a competitive performer on Sony cameras? Find out below. The Contax G 28mm Biogon was considered one of the best 28mm available on film, but suffers serious issues on digital due to sensor cover glass.
