400mm is f/5.6 -> on both lenses
Peter, I am not being contentious, but the TAMRON SP AF 200-500mm f/5-6.3 Di LD is f/5.6 @ 400mm, just like the highly touted SONY AF 70-400mm f/4-5.6 G SSM, there is no difference in base aperture between them.
The image quality is better ... but, you are paying for it. 400mm is not my preferred shooting length ... and having the TAMRON solves the issue well enough, for the moment, by my having the 70-200mm f/2.8 (a much more useful 'base' aperture). Should matters change, that will be one thing ... but I cannot "write it off" and since I have the range covered ... it really seems kind of pointless, for a rare shot.
I appreciate the suggestion ... perhaps, next year.
@Rooz: If I want an A700-style shot out of the 200-500, I can opt from the "menu" and switch the α850 into APS-C crop mode, effectively cropping the image to 750mm. That's a reach, huh? :rolleyes:
Broadening my photographic horizon
It boils down to Options, Ryan ... I now have a whole new set of options with this camera, that the α700 simply could not offer. I did try to explain that when I made this decision. You might want to review some of the last month's postings in that regard.

It immediately lops off the "unused" or vignetted portion of the lens FOV and provides a dandy looking shot.
I also have a KM AF 17-35mm f/2.8-4 'D' which, until I got the α850, had no use in my bag at all. Now, it is my widest zoom for the full frame.
No, Ryan ... my photography is spreading out in new and fun ways. It is explosive in its own regard ... and with my current schedule, for the rest of this month and the next, just a little overwhelming.
I fully expect a wave of new lenses will come my way in the upcoming year ... I'm in no hurry. No pressing issues in that way, thank God. :o
One thing for sure, I did not buy the Full Frame as an excuse to go on a glass binge. :p I'll leave that thunder, to the man Down-Under.
I agree with the idea of having the AF 70-400mm f/4-5.6 G SSM lens ... but, I need to remind you that some lenses were "building" lenses ... waiting for SONY & TAMRON to get their acts together and basically were there for use on the Minolta Maxxums I have and the early α100. Things have changed and some lenses, specifically the TAMRON AF 70-300mm f/4-5.6 LD are not used by yours truly any more, except for comparisons. Since the purchase of the 70-200mm f/2.8 and the 200-500mm f/5-6.3, the Tokina ATX-840 AF 80-400mm f/4.5-5.6 does not get much use, either. Having a choice of wider aperture is always nice.
You really need to recall that once TAMRON released the SP AF 70-200mm f/2.8 Di LD ... it immediately filled the year-long, wide-aperture gap I had, after return my OOTB-defective SONY AF 70-200mm f/2.8 G SSM. This just is not a hole that I feel I need to fill, yet.
Optical shortcomings ... mass manufacturing

So, there is that aspect (You have got to be kidding - SONY should allow for non-SONY additions w/o wiping out the entire registry ... this feature is KIND OF IMPRACTICAL in its current form).
Truth be told, the better lenses should not need one skosh of adjustment. For example, the Minolta AF 200mm f/2.8 APO G HS is "dead nuts", as they all should be. I have gone to great effort to get most of my lenses in such condition and AF Micro-adjust, to me, is just the industry's way of compensating for poor manufacturing Quality Assurance/Quality Control of their shoddy optical products. If you are going manufacture something ... do it correctly. That extra step may cost a buck or two, but it is deeply appreciated by those looking to have sharp and excellent work, without having to struggle with every single mount of a lens.
If I wanted to futz with lenses, I would have bought a Canon or Nikon, where even STABILITY is a reach! I gave that up three years ago! :mad: SONY offered a solution that simply made a lot more financial sense than the proprietary design of the other two. If Canon and Nikon really were concerned about Image Stability, they would have put it in BOTH the camera and the lenses. Then, everybody would be happy.
Obviously, we are left with two camps, here:
- people who have stability with ALL their mounted lenses ... and
- those people who only have a few lenses with added stability ... everything else shakes handheld w/o support.
Oh, I digress ... I guess I am still annoyed with the direction it went. Sorry. :rolleyes:
Hmmm ... where did we turn incorrectly?
One of the drawbacks of the AF Micro-adjust is that its registry ONLY works on Minolta/Konica-Minolta/SONY lenses. If you add a non-SONY lens and AF Micro-adjust it ... it has the potential of throwing off the entire previous lens registry. Uh ... now, that is confusing. :confused:
