Top must-have accessories for OM System OM-1 photography?

Seconding the recommendation above. I actually learned that lesson the hard way too... I bought some cheap cards once and my OM-1 basically felt like a turtle during a birding trip. Not fun! Honestly, I'm a bit of a cautious shooter, so I usually prefer sticking to official gear when it comes to power and storage to avoid any weird glitches or reliability issues. I've been using my OM-1 for a while now and I'm super satisfied with how it handles, but you gotta be careful with your choice of accessories. Here is a quick comparison of what I've tested: 1. **Power: OM System HLD-10 Power Battery Holder vs. OM System BLX-1 Lithium-Ion Battery** - The grip is amazing for wildlife ergonomics. It makes the body feel way more balanced with big lenses. Plus, you get that extra shutter button for vertical shots. - But if your doing mostly landscapes, I'd just stick to 2-3 extra BLX-1 batteries. The grip adds a lot of bulk and weight that might not be necessary for a tripod setup. - Just a heads up: I really recommend avoiding third-party batteries. I'm pretty sure I've seen too many reports of them failing or not communicating right with the charger, and it's just not worth the risk to the camera. 2. **Storage: Sony SF-G Tough Series UHS-II SDXC 128GB vs. SanDisk 128GB Extreme PRO SDXC UHS-II V90** - The Sony Tough cards are my go-to. They are literally built like a tank and dont have those flimsy plastic ribs that always break off in the slot. - The SanDisk is a great alternative and usually cheaper, but I've found the Sony to be slightly more consistent when clearing the buffer during high-speed bursts. 3. **Support: 3 Legged Thing Ollie L-Bracket for OM-1 vs. SmallRig L-Bracket for OM System OM-1** - I use the Ollie. It’s pretty good because it has a specific cutout that lets you actually use the side ports and flip the screen more easily than others. - SmallRig is okay, but it can be a bit fiddly with the cable doors. Anyway, I'm pretty happy with my setup now. The lesson I learned is that cheaping out on accessories for a pro body like this usually leads to frustration. Just dont skimp on the card speed like the first reply said! Cheers. 👍

Sooo when I first got my OM-1, I actually tried using my old V30 cards and let me tell you... it was a total disaster. I missed a literal once-in-a-lifetime shot of an owl because the buffer took AGES to clear. Lesson learned: dont skimp on speed or youll regret it! Here is what I recommend based on my setup:
* For those insane bursts, the Lexar Professional 2000x SDXC UHS-II 128GB is a beast. Highkey, V90 is the ONLY way to go for wildlife.
* I am always cautious about power, so I suggest sticking with the official OM System BLX-1 Lithium-Ion Battery. I have heard some horror stories about third-party ones swelling up.
* The SmallRig L-Bracket for OM System OM-1 3661 is GREAT for landscapes. It basically stays out of the way of the side ports. I guess the grip is a decent option, but maybe try just the L-bracket first to see if ur hands get tired. gl! peace

Had a moment to think about this more and honestly, this^. Also wanted to add my two cents. Totally agree on the V90 cards... you literally cant skip that for those 50fps wildlife bursts. But honestly, ive gotta warn you about a common mistake I see folks making: - Careful with cheap generic batteries. In my experience, the OM-1 is super picky. Some knock-offs wont even let you hit the top burst speeds or might even swell up.
- Dont rush into the official battery grip. It's pricey and adds a ton of bulk. A decent L-bracket with a sliding side-plate is way cheaper and keeps those ports clear for landscape cables. Honestly, just get a solid USB-C PD power bank. It’s way more cost-effective for long exposures... i mean, it basically lets you shoot all night. gl!
