Question?
« on: December 15, 2012, 07:31:32 PM »
Does the SONY 16-50 2.8 work on the a99? I'm a bit confused [ :-[ ] as I'm thinking the lens is an apsc lens because of the DT initials on the barrel; DT 1650 2.8 SSM.

I may.... only "may"... be thinking of an a99 at some point next year and wondering which glass works with it - again somewhat confused as I recall something about not all Minolta or Sony glass will work with the a99. :-[

Frank, the DT on a Sony lens indicates an APS-C format lens. It will work on an A99 I believe, but at a reduced resolution. All the Minolta and Sony lenses are still compatible with the A99 but only some of the Sony lenses are compatible with a new feature. I can't recall the name of the feature right now.

I have  had my eye on an A99 since they came out. As a stopgap I have purchased an A77. I am unsure what to think of the A77, my gut feel tells me it is a glorified Point & Shoot with some admittedly good features. The jury is still out. This may well affect my decision to purchase an A99. :(

Thanks Ascot - appreciated. I thought that was the case with the 1650

I have the a77 with the 1650 - which seems to be less available sold together :( ... I do enjoy using it although I've not posted as many shots to the forum as I'd have liked to have since getting it.

I am just... thinking about the a99 although it and the a77 have some similarities but differences which are making me undecided... SONY seem to have cut back on some available specs on the a77 with the a99 - frames per second I think [ :? ] is one of them, the 99 taking less than the a77.

If I do go a99 I wanted to be able to use most of my Minolta and 'older' Sony glass and flash but I think there is also some differences with the flash mount? I have a Sony HVL-F43 and 58 plus a couple of Minolta Program 5400HS units...

Frank I am looking and reading.In my reading I came across a review in DPReview.
Normally I avoid DPR because of the rude people but this will tell you all you need to know about the A99 until Michael Friedman gets his book out.
The A99 uses an ISO flash mount but an adaptor is provided in the box for Sony flashes ....john

Frank,

This is from the a99 manual. When a DT lens is attached or [APS-C Size Capture] is set to [On] in the Setup
menu, a live view image is displayed in full screen view on the LCD screen with the angle of view of the APS-C size. The live view image in the viewfinder is also displayed entirely and you can check the composition or effect using the whole screen.

I can verify that following lenses work with a99: Tamron 70-200mm f2.8, Tamron 17-35mm, Minolta 300mm f4, Minolta 100mm f2.8 Macro, Sony 135mm STF, Sigma 50mm F1.4 HSM and CZ 24-70mm f2.8.

All lens will work even the APS-C/DT lens. What you have to consider is that the AF-D autofocus function and AF-Range will not work with after market lens (especially SIGMA).
Some sigma user complain that when the enable AF-Range that the camera will not focus at all.
I don't have any non Minolta /Sony lens but maybe Sony since is partner in Tamron they may allowed only the AF-Range  function but not the AF-D function.

AF-D Function will be for a long time only for PURE SONY and maybe only for full frame lens.

Thanks John, Kurt, Rex... much appreciated :)

I have two Sigma lenses at this time; the 105/2.8 Macro & 135-400/4.5-5.6 APO... and I'm not thinking of getting any other Sigma glass.
My other lenses are;
Minolta 50/1.7, Minolta 100/2.8 Macro, Minolta Mirror 500/8.
Tamron 17-50/2.8, Tamron 28-300/3.5-6.3 and Tamron 11-18/4.5-5.6.
Sony glass; DT 1650/2.8, DT 30/2.8 Macro, DT 55-200/4-5.6, DT 18-70/3.5-5.6 (came with the a700), 70-400G/4-5.6 - and I'm not counting the 70-300/4.5-5.6 'nicked', 'borrowed' by the lad!
