Larry in Virginia is looking for advice in moving from his Canon 5DMkIII to a Sony A7III. He says:
I'm a Canon 5DMkIII shooter considering the Sony A7III for my real estate work with an adapter and my Canon 17-40mm L to lighten the load a bit. My 17-40mm has been the workhorse for my work. I rented the Sony and discovered the image format is ARW. Lightroom Classic 7.2 does not recognize ARW files but 7.3 does. However, I've read about various bugs in 7.3 and I'm hesitant to upgrade yet. But the way I've found to use ARW files is to convert them to TIFF using Adobe DNG converter and that is a pain. Anyone have a workflow tip here they can share? If you've upgraded to 7.3, how's it working for real estate?
There are two issues here. Lightroom Classic CC 7.3 and using Canon glass on Sony full frame bodies with adapters. Let's address them one at a time.
Lightroom Classic CC 7.3 Problems
Yes, Lightroom Classic CC 7.3 initially had some problems. When I first got Larry's question, Adobe had not released a fix for the problems but as I write this (4/24 morning) Adobe just released Lightroom Classic CC 7.3.1 which I've just installed on my backup machine. I recommend that everyone who depends on the operational reliability have a backup computer to verify the integrity of the software before you starting using it in your production workflow.
Canon Glass on Sony Full-Frame Bodies
I have plenty of Canon glass but I don't have a Sony full-frame mirrorless body. The research I've done indicates there are some downsides to using adapters for Canon glass on Sony full-frame mirrorless bodies; particularly with wide-angle lenses like real estate photographers are likely to be using. This video by Tony Northrup is just one such example. My conclusion is that you get the best results by using Sony G Master lenses on Sony mirrorless bodies. Does anyone have direct results with this?
