For the first time in several years with many cards, my Mac ImageCapture is getting errors downloading a few specific images off the camera. I tried multiple times. Perhaps the card has some corruption on it (it's not an old card). Does the camera have any way of fixing the issues during Formatting or I should do it out of the camera (on a computer with an app for data recovery and file system check)?  It's an expensive high-end SD card so I don't want to just throw it away. What's the best way of handling those kinds of errors?

Funny story, I had an SD card that always corrupted one specific photo. What I think it happened was thet some bits were flipped when writing to that specific region. I could still download the photos but opening them they were half pink and half distorted. I kept using that card eventually since I only did photos for my self but after a few years I upgraded to something else because of the size of the card.
 

Now to answer your question: I would low level format it in camera or in Mac a few times and I'd use it in order to test it if it fails. Benchmark it, write some files on it, fill it up, copy the files back, etc. Stress test it. It it fails under the stress test, then you need to buy another card, if not and only some files are corrupted, then expect that it will go bad (or it might not, but assume it will) and then ask yourself if it's woth buying a new card now or losing some photos and buying it later.

Now it depends on how much do you care about that photos. Working for a client? Buy a new card. Hobby? If it's bothering you buy another card or use the second slot to save JPEG/HEIF and download the corrupted files from there.

BTW, I never got rid of the corruption of only one photo on that card.

If it's an expensive card, it should have a warranty - I'd recommend asking for a replacement. The maker of the card probably doesn't get a lot of warranty claims, so they'll probably simply replace it.

    • I've been using this lens extensively without any sharpness issues. At long focal lengths, you'll have to factor in the need for a faster shutter speed (< 1/500-ish at 350mm) and other factors like atmospheric distortion, fog/dust haze, etc. All these factors contribute to a deterioration of image quality at longer focal lengths.
    • That's supposed to be a pretty good APS-C lens. Can you try it on a different camera just for the heck of it? Friend? Camera shop? The lens is noted for sharpness, so if you're having as much trouble as you say, you may want to look into a replacement or repair. 
    • Hi everyone, I’m reaching out to the community because I’m facing a persistent image quality issue with my Sony 70–350mm f/4.5–6.3 G OSS lens, and I’d like to know if this is normal behavior or if my copy is defective. Problem description: I’ve extensively compared the 70–350mm G OSS with my Sony 18–135mm f/3.5–5.6 OSS, using a Sony A6700, under controlled conditions: • Identical lighting and background • Same subject and position (LEGO figure, consistent framing) • Tripod or steady support • Manual focus or AF with center point • Same shutter speed (e.g., 1/200s), similar ISO (ISO 4000–6400), RAW + JPEG • OIS turned on (and also tested with OIS off) My observations: • At 135mm, the 70–350mm G OSS delivers softer, flatter images than the 18–135mm, even when stopped down. • At 350mm, the sharpness drops significantly – the center is soft, and textures (like LEGO tiles or fabric) appear blurred or smudged. • Contrast and micro-detail are noticeably inferior across all focal lengths. • The 18–135mm at 135mm (even cropped) retains better edge sharpness and detail definition. • Both JPEG and RAW files confirm the issue – this is not just JPEG processing or noise reduction. Question to the community: • Have others experienced similar softness with the 70–350mm? • Is it possible I have a decentered or optically misaligned copy? • Is there a known issue with OSS introducing softness at long focal lengths? I wanted to love this lens due to the range and portability, but currently it’s unusable for anything where image quality matters. I’m considering returning or sending it for service. Thanks in advance for any feedback or comparison results you can share.
