FS: Sony a7R IV (Body only)

I bought this new from a US authorized retailer a couple weeks ago at a discount, and I am further discounting it here. It's wild overkill for me and I'm disappointed with the ISO performance. Condition is like new. Sale includes everything that comes with the retail package, including the box. Also includes original receipt. Price is $2800 net to me. Local NYC (Midtown) preferred. I'll try to get some pictures up tonight, but it looks like a new camera.

 

Very tempting...

 

I’m mostly curious what you don’t like about the ISO performance. Sony is class leading in that regard

 

In my opinion, the A7III has leading ISO performance but the RIV isn't close. Sony claims the RIII and RIV have the same ISO performance but that's just not true. A couple reviewers have admitted that the difference is closer to 2 stops, and the III is better than the RIII in that regard. Many reviewers are downsampling the RIV shots to match RIII resolution to compare noise, which kind of defeats the point of having the increased mp. Granted, at base ISO the RIV is absolutely insane. But I'm just a random guy so don't take my word for it.

 

CMOS is approaching physical efficiency boundaries so it's practically impossible for new sensors to perform on par with old but lower resolution sensor on a pitch by pitch basis. We're talking about max 10% better low light performance without some kind of near magical gain in fabrication or material science breakthrough. So if the individual wells are 40% smaller at best low light performance is still going to be worse by 30% (but maybe a bit better with downsampling).

There's also a bunch of stuff about the strength of the color filters that's really hard to quantify, but the bottom line is that color fidelity at base ISO is always going to trade off on high ISO performance. If you're looking for a 60MP camera that can be cropped to 24mp and outperform a A7III, you'll have to wait until someone builds an organic sensor or something.

GLWS, though. I tried the mk4 and coming from the mk2 I found the grip too fat and will probably get a mk3 or wait to see if Sony will ever make a compact FF ILC.
