Just catching up on this thread and man, I totally get the frustration. Its honestly ridiculous that we have to basically re-engineer the camera ourselves just to make it usable. The current state of things is pretty bad:

• The ergonomics are a complete joke. It drives me crazy that companies release these sleek designs that look good in marketing photos but are basically impossible to hold securely without buying extra parts.
• It feels like a total scam when you realize the base price of the camera is just a starting point because the battery life is so abysmal you cant actually use it for a full day of street work without carrying a pocket full of spares.
• The accessory market has become a way for brands to ignore basic design flaws while charging us a premium to fix them. Its such a massive headache for anyone trying to stay within a reasonable budget and just want a tool that works out of the box.
• Honestly, the lack of consideration for real-world handling is insulting at this point.

> The ergonomics are a complete joke. It drives me crazy that companies release these sleek designs that look good in marketing photos but are basically impossible to hold securely Building on the earlier suggestion, I totally feel that frustration. I remember trying to track a subject through a crowded subway station and the fp nearly slipped because my palms were just slightly damp. Its a data problem really... the surface area of the body is just too small for the torque of even a compact lens. I ran some tests comparing the Sigma Hand Grip HG-11 against the SmallRig Cage for Sigma fp Series 3211. The SmallRig setup is technically superior for street because it shifts the center of gravity closer to your palm. I also ditched the standard cells for a SmallRig NP-F Battery Adapter Plate Lite 3018 paired with an NP-F battery. It adds bulk, sure, but the milliamp-hour trade-off is massive compared to the standard Sigma BP-51 Li-ion Battery. You get roughly 4-5 times the life. Tbh, for under $400 you can grab both and still have cash left over.

Adding my two cents here since I've been through the ringer with this tiny brick. Honestly, i spent more time trying to fix the fp than actually shooting street with it at first. It's such a letdown how slippery it is out of the box... i almost chucked mine into the hudson after it nearly slid out of my hand during a rainy shoot. Going the DIY route was the only thing that worked for me because the retail stuff felt kinda cheap and was way too expensive. Found some amazing 3D printing communities online that have files for custom grips that actually fit a human hand.

• search for open source cad files for camera grips
• check out local 3D printing services if you dont own a printer
• look into external power bank hacks for longer street sessions the setup i built involves a custom printed handle and a massive power bank i found online velcroed to my strap. ngl it looks like a science project but it beats dropping a $2k camera. definitely check out those maker sites before you sell the thing tho.

I was so happy once I fixed the handling on mine. It works well for street.

• better grip
• more power You looking for a cage or just a simple grip?

I've had mine for a while now and honestly, I'm satisfied with how it handles after some trial and error. It works well for my workflow, but you really have to be careful about what you bolt onto such a small chassis. Before I give you a list of parts, are you planning to keep it as compact as possible for street stuff, or do you mind if it gets a bit bulky? That changes my perspective on the power situation. A few things to watch out for:

• Avoid cheap third-party dummy batteries that lack voltage regulation. I've seen too many horror stories of people bricking their sensors trying to save twenty bucks.
• Stay away from grips that don't have a pass-through for the battery door. It sounds minor until you're fumbling with a hex key on a sidewalk in NYC.
• Watch out for some of those ultra-cheap thumb rests that use the hot shoe. If they don't have a locking mechanism, they can wiggle and eventually damage the pins. No complaints with the camera itself, you just gotta build it out with reliability in mind.

Just saw this and had to jump in because I dealt with the EXACT same thing when I first got my fp for shooting around Brooklyn! It felt like holding a bar of soap at first, right? Seriously, I almost dropped mine twice before realizing I needed to rig it out properly without turning it into a giant cine-brick. For street stuff, you want it tactile but fast. Spent a ton of time on YouTube looking at setups from guys like Richard Wong... seriously helpful resource for seeing how others build these. Heres what saved my sanity while staying way under that 400 dollar budget:

• SmallRig Cage for Sigma fp and fp L 2225 because it gives you a real handle to grab and extra mounting spots
• Haoge THB-FPB Metal Thumb Rest which is literally amazing for one-handed stability
• Wasabi Power Battery 2-Pack for Sigma BP-51 so you can just swap them out fast without spending a fortune Honestly that thumb rest plus the cage made it feel like a completely different camera. Love the images coming out of it now, its such a fantastic little beast once you tame the ergonomics! Dont give up on it yet, it just needs a little love tho.
