Facts.

Just saw this and honestly, you should really look at the market research before committing your whole budget. Sony is leading the pack on third-party lens variety right now, which is a huge deal for wildlife, but you have to be careful about the hidden costs that come with high-end mirrorless systems. Dont just buy into the hype without weighing the ecosystem as a whole.

• Check the cost of high speed cards because they add up fast
• Look at how the body balances with the specific lenses you want
• Research the autofocus tracking reliability in low contrast scenes specifically Tbh, I would be pretty cautious about dumping your entire budget into the newest body. I have seen too many people grab a top tier camera and then realize they cant afford the glass that actually makes the wildlife shots pop. Basically, prioritize the system over a single spec sheet.

George is spot on about those hidden costs... especially the CFexpress Type A tax. If you compare the Sony Alpha 7R V Mirrorless Camera to something like the Nikon Z8 Mirrorless Camera, the Nikon uses cheaper Type B media but the Sony ecosystem gives you access to the Sony FE 200-600mm f/5.6-6.3 G OSS, which is arguably the best value wildlife lens across all brands. Quick tips:

• Look for stacked sensor specs. Its the only way to get true blackout-free shooting for tracking birds in flight.
• Check the buffer depth data before buying. High megapixels mean nothing if the camera freezes after two seconds of continuous shooting. If you can stretch the budget or find a deal, a used Sony Alpha 1 Mirrorless Camera is the only body that truly checks every single technical box for wildlife without compromise.

I've chased elusive foxes with my Sony a7IV. The autofocus is stellar, even with adapted Canon telephotos. Got mine used for $2500 – leaving budget for glass.

Consider the a7R V. Its focus stacking and pixel shift resolve detail; consult a pro for optimal setup.
