Which CFexpress Type A cards are recommended for the Sony a7R V?

Question

I just picked up the a7R V last week after shooting with the R IV for years and man the file sizes are still crazy but that new processor is something else. Im planning a big landscape trip to the Dolomites in three weeks and I realized my old UHS-II V90 cards are probably gonna struggle when I start hitting the shutter for some of the wildlife stuff or if I try out the 8K video mode just to see how it looks.

I know the Type A cards are way faster for clearing the buffer but the price tags are just brutal honestly. I see the Sony Tough cards everywhere but then I see brands like Pergear and Exascend for like half the price and Im hesitant because I dont want to lose footage on a trip I spent three grand on. I have about $400 left in my gear budget for storage so I need to make it count. Are people seeing any real-world thermal issues with the cheaper brands during long bursts or 8K recording?

Which specific CFexpress Type A cards are you guys actually using and trusting in your a7R V right now?

^ This. Also, I have been shooting with the Sony system since the early A7R days and I have found that while the budget brands are tempting, mid-tier options like the Lexar Professional Gold Series CFexpress Type A 320GB hit that sweet spot you're looking for. I am currently using a pair of these in my a7R V and they handle the 8K 24p video and high-speed bursts for birds in flight without breaking a sweat. No complaints so far, and the thermal management seems solid. The a7R V handles heat much better than the older bodies, but if you are hitting the shutter hard for wildlife, the card will definitely get warm. I havent seen any real-world thermal issues or slowdowns with the Lexar or the ProGrade Digital CFexpress Type A Gold 160GB. Both brands are well-respected in the industry and provide that extra layer of confidence when you are on an expensive trip like your Dolomites one. If you want the absolute highest reliability, the Sony CEA-G Series CFexpress Type A 160GB is still king because of the physical build quality. They are basically crush-proof and waterproof, which is nice for outdoor landscape work. But honestly, for your $400 budget, I would go with the Lexar 320GB. It gives you the capacity you need for those massive raw files while staying within your price range. Just my two cents from a few months of heavy use.

^ This. Also, while those budget cards seem fine on paper, I was honestly disappointed with the sustained write performance during a long landscape session in the Rockies last autumn. Ngl, they start off strong but once that buffer fills up on the a7R V, they tend to throttle way harder than the premium stuff. It's pretty frustrating that Sony locks us into this Type A ecosystem where prices stay high while Type B is dirt cheap. If you have $400, skip the bottom-tier stuff but dont feel forced into the Sony tax either. I ended up trusting the ProGrade Digital CFexpress Type A 160GB Cobalt because it actually has that VPG-400 rating for 8K stability. If you need more room, the Exascend Essential CFexpress Type A 240GB is a solid middle ground that hasn't overheated on me yet. Just be careful with the ultra-cheap brands... losing shots in the Dolomites over a $50 saving would be soul-crushing.

> the price tags are just brutal honestly. Tbh I suggest the Pergear CFexpress Type A 260GB since it is way cheaper. It handles 8K perfectly and saves you some serious cash.
