The Sony a99 Mark II, Sony RX100 V and Sony a6500 are now supported by DXO Optic, but the release notes haven’t been updated to reflect to the support yet. The will your camera work section has been updated here though.
An interesting review by DPReview because you can’t compare the results directly to any other camera in their database and the AF performance isn’t very impressive in their test. DPReview’s results differ from other reviews that have demonstrated much better performance.
“the a99 II is the ultimate SLT. It is the SLT that should be used by any photographers that have had prior doubts about the system, as its all-round balance of features and capabilities leave the ultimate decision for many photographers up to two things: EVF vs. OVF, and the lens system. For those that love SLT, the a99 II is definitely worth a look, but for those that need a solid all-rounder, or a lens selection beyond A-mount, the complications of SLT may not be worth the advantages.”
At least the image quality hold up well. You can read their full review here.
Rayqual is producing a unique M37 screw mount adapter for AsahiFlex lenses.
Asahi Flex of Asahi Optical Co., Ltd. is the first domestically manufactured 35 mm single-lens reflex camera that appeared in 1952.The mount is a screw type with a diameter of 37 mm and is often called M37 mount.This mount, the caliber is smaller than the 39 mm of the Leica screw mount, but the flange back is the most delicate specification of 45.5 mm which is the same as the M42 mount.If you are wearing a camera, you will come up with a way to attach a 37-42 mm conversion ring to the lens and use it with the M42 mount adapter.
It’s always nice to see classic systems brought back to life. Kind of interesting that the flange back distance wasn’t consistent though.
First of all, it is flange back variation.Although I do not know whether it is due to manufacturing or due to secular change, the existing body of Asahi Flex seems to have variations in flange back as it is said.Rayquar gets 7 to 8 ASAHI flex bodies, measures flange back, calculates realistic flange back figures with variations added.I am designing a mount adapter based on that.
The new Sony lenses that were just announced are somewhat impressive, but not a lot is known about them yet. So far there are a lot of videos available and Sony’s image gallery, but there isn’t a lot of information about how the ADP element affects AF yet. Fujifilm’s ADP lens is unable to utilize PDAF, which is a pretty big disadvantage beyond the loss of light, but if you’re into this kind of lens it should be amazing.
