Hi everyone. I'm having a pretty strange problem that I can't find the answer for anywhere. I have a Sony A7C and am shooting in RAW, which is officially supported by Mac OS. Usually I can open my photos no problem in Preview, but recently I am unable to open some, but not all of the photos. Once or twice a couple of photos weren't able to open before, but recently sometimes as many as 100 of the photos I took during a shoot can't be opened by Preview. 

When I try to open one of these photos, I get the message "The file “(file name here)” could not be opened. Preview currently does not support this raw file format." But most of the other photos I can open no problem. It seems rather inconsistent. 

I'm also able to open the photos that can't be opened by Preview in Imaging Edge no problem, further confusing me. 

I'm having this problem on both my 2021 M1 Pro Macbook Pro and my 2019 Macbook Air, for a little more context. 

Any insight into why this strange problem is happening would be appreciated!

      Looking for an a7R mk I, (second generation)

      By NewSonyUsER · Posted

      I'd really like to find a package deal for an a7R (mk I, second generation) which includes the neckstrap and box. I've searched Ebay and currently no one is listing what I'm looking for. They either have the camera only or a first generation a7R and a lot of them don't offer the Sony neckstrap or box it came in. I know your site doesn't have a formal 'Equipment For Sale' thread and granted Ebay is a better place to sell gear but I thought I'd see if any of the members have one and would like to upgrade to a newer model but don't think anyone would be looking for one that old. The cameras I've been using are in the 20 megapixel range and rather than jumping to a 40mp camera due to file size, the 36mp that the first a7R has was appealing to me and wouldn't break the bank. I've been using Canon and Nikon but really want experience a Sony. If a post like this is undesirable for this website, I understand but I thought I would ask. Thank you.

      Any A7R iv A issues with 200-600 zoom?

      By SonyFF32137 · Posted

      Here's a good thread on the issue.... https://www.dpreview.com/forums/thread/4571046 And here is the info on the A7RIVA that maybe explains why I don't see the issue...  The change in wording that caught my attention is that the new A7RIVA brochure says the structure has been "re-examined and redesigned." Don't know, but given the text of other parts of the brochures are copied word for word, the change in text here seems significant. My reading of this is that it is a redesign of the A7RIV. In that case, perhaps the 200-600 issues are less severe with the new body.

      2 Primes or 1 Zoom?

      By XKAES · Posted

      I'd opt for a small zoom, but I must admit that there seems to be a dearth of lenses in the e-mount in the 24-50mm range -- for some reason.  I have a small 24-70mm, but that's an a-mount Tamron.  Maybe you can find something by looking at lenses slightly longer.  I have a heavy, but small 24-100mm a-mount, and Tokina made a 24-200mm a-mount.  Maybe there are similar lenses in the e-mount.  Kill three birds with one stone.
