woundering about some birding lenes.
I Have been looking for a nice birding lens for some time now in the 400mm to 500mm range , I would like to stay in the 500 dollar range. So that means i will have to buy used if i want a good lens. I have been burned with buying a older sigma 400mm prime lens with the AF gear stripping out .But that does not mean i won't buy sigma i just will be doing more research and asking others what they think. I was looking at a Sigma 135-400mm f/4.5-5.6 AF Mt APO Lens has anyone used one of these or could anyone send me in the right direction.
Angry response ... apparently lasting for years
I talked with Tokina Corporate Sales, back early 2007, and addressed the SONY-mount issue when I wanted the digital version of the ATX-840 (Model III), before I got my Model I. Tokina was only making the 5-contact lenses, so I am assuming they only had limited interest in Minolta's "film" line of cameras ... and not even the newer ADI (8-contact) ones (Maxxum 7 and Maxxum 9).

- Only Nikon and Canon mounts were available in the newer Model III.
- Only the Model I & II were available in the A-mount ... and very few of these were produced and available in the A-Mount.
It is only since last year that Tokina began to make just one lens in the A-mount for we SONY users, again, and that is the AT-X 116 PRO DX 11-16 f/2.8 Ultra Wide Angle. It is a very unique offering, having f/2.8 at such a wide focal length, so it looks like a pretty good niche market approach. SONY's own 16-35mm f/2.8 Zeiss ($1899) lens is really f/3.3, but who's looking, right?
A caveat to this particular lens release is: According to the Dyxum lens database, this "new" Tokina lens STILL does not have operating "D-type" (ADI) contacts and is, from my perspective, an AF lens with the "original" A-mount on it.
Tokina is, only now (albeit very slowly), allowing any commitment to A-mount and have what I would term, a "guarded interest", based on SONY's Alpha-camera sales worldwide. Over the years, I have heard, through various vendors, that a 20% marketshare will have to be achieved before Tokina would open the A-mount floodgates, again.
Chances are, SONY is not going to be licensing the 8-contact (ADI) technology and, as we know, SONY, of all companies, has demonstrated they are not the most "sharing" of their own technologies. They love to create proprietary items and that has never been good for the photography buying public. If they ever kill a product or technology-type ... it is a one-off and it is DEAD! :eek::mad::p
This is one man's somewhat informed opinion (I contest that it is shared by many others) and "the way I see it." If you get a different take on this entire affair when you are contacting Tokina, I would appreciate you posting it here and letting us all know about it. Whatever was going on between Tokina and Minolta ... it is probably more of the same with SONY, only there is even less communication.
Arguably, with Tokina manufacturing only two FULL FRAME lenses (the 100mm f/2.8 MACRO and the AT-X 840 80-400mm f/4.5-5.6) for ANY camera mount, my personal interest is what I would call ... "marginal." But, for the rest of the APS-C sensor crowd, you guys should push for ADI-capable A-mount in Tokina's "DX" lenses as hard as possible, as variety is often key to photographic production.
BTW: Here is the 2007 DCRP thread concerning the Tokina lens issue
Problem is, Darin ... it is the same old question ... four years later! For THK ... that's a lot of lost revenue, but then again, if SONY would quit its continuous vacillating ... life might be better for everyone.
