Recently, I purchased the A99 and I find the difference between the A77 and A99 startling in almost every way. The A99 capture/image quality is completely beyond the reach of the A77. I really didn't expect that.

And the "bland, neutral-subject test" was done with separate lenses - an APS-C lens for the A77, and full-frame for the A99, eliminating the theory that the A77's sensor was only absorbing a fraction of the full-frame lens' light (even though that would have resulted in the A77's images being darker - the opposite of what was observed.)

My thoughts are with you in the coming months as you sort everything out.<br /><br />Regarding the A99/77 differences, it sounds like the A99 iso is overstated by about 1 stop, i.e, an iso of 100 is actually 50. Whether intentional or not, it would make the camera's high iso performance appear better than it actually is by about 1 stop. Does that make sense?<br /><br />Take care,<br />Mike HendrenAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7913915168052873347.post-30350754764316768382013-07-23T21:50:43.921-07:002013-07-23T21:50:43.921-07:00Hi Gary - three brief thoughts on the exposure thi...Hi Gary - three brief thoughts on the exposure thing. When they review cameras in dpreview, they give the actual ISOs against the nominal ones, because apparently they aren't the same. Also, in the film biz, we had what we called "t-stops," which were the real f-stops when calibrated against a good meter. Finally, the two cameras are different frame sizes, so the zoom setting would be different for the same composition. Could that affect exposure differences?<br /><br />Enjoying my new a77, posting on dpreview.<br /><br />Gary Eickmeier (other Gary)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7913915168052873347.post-51639138833105759472013-07-23T12:49:35.320-07:002013-07-23T12:49:35.320-07:00Many thanks, Ant!

There are estate liquidation companies that specialize in attacking properties like your father's and dealing with everything for you, typically taking about 35% of whatever they can get (which when your time and emotional charge are taken into account is quite a bargain!)<br /><br />According to the DxOMark measurements the a77 is spot on and the A99 is low. My understanding is that ETTR (Expose-to-the-right) doesn't work quite as well on the new Sony models since they tweaked how the light distribution is represented in the RAW files. <br /><br />GFGary L.

Thanks to your help I decided one the one I could afford :-) <br /><br />That being said, I was about to email you with my results and ask how your mother in law was doing when I found your blog email actually in the 'junk' folder in hotmail! If it wasn't for me checking whats in there daily Id have missed it, it apparently came from 'no sender' and 'no subject' no idea why.<br /><br />Please accept my condolences for your sad loss, a bereavement is a trying time for one and all. My father is a hoarder of massive proportions, by that I mean two 60x40ft 12 ft high 'garages' full to the roof and doors, and approximately half an acre of stuff outside. And he's just treated himself to three new 10x8 sheds for more! Oh and a caravan that nobody can get in too not to mention the house :-) Dread isnt the word! <br /><br />Just a quick question (Gary runs for the car with family in tow) no it really is quick :-) how do both the A77 and A99 compare with a true 100ISO base line, in short, which is the truer value? Do we need to drop the exposure on the A77 or up it on the A99? Does it really matter? ETTR comes to mind which I find helps a lot with the A77. <br /><br />Enjoy your break, and Im sure your seminars will look after themselves. That sculpture is something else! Love the photo and explanation of how it was achieved. <br /><br />Kind regards<br />DazDazhttps://www.blogger.com/profile/02167738385636490418noreply@blogger.comtag:blogger.com,1999:blog-7913915168052873347.post-78038376825929688302013-07-23T05:50:58.122-07:002013-07-23T05:50:58.122-07:00Curious to read about the A99 v A77.
