EOS R7

Canon r7 pixel size 3.2 micron. Zwo asi678mc (not even that high end in the zwo lineup) pixel size 2 micron. Now, the proper pixel size depends on many factors we don't know, but generally speaking for planetary imaging you need high pixel density more than brut sensor size. And a dedicated planetar

It depends on the camera and what you’re comparing it to. For me personally noise hasn’t been an issue since the day both companies finally retired the classic 12MP Panasonic LiveMOS sensor. All 16MP and 20MP sensors have been fine, and the latest 25MP sensor in the G9ii is actually better than Cano

I’m using the Sigma 150-600 f5-6.3 contemporary. I think this is the same lens as yours. It works very, very well with my R5mkII. The reason for this is the faster sensor readout speed on the newer Canon R-series cameras. The only cams I can confirm this lens works well on are: R5mkII R6mkIII The ma

The AF area is exactly what's outlined on the EVF. These things are nothing like a DSLR where the AF sensor is a completely different part of the camera. In a DSLR, it wasn't uncommon for AF points to be misaligned with its depiction in the viewfinder because the LCD in the viewfinder didn't need to

I agree. The 90D is an excellent low light astro camera. The Canon 90D and the Canon R5 are the two cameras that I have tested and/or seen data for that show impressive low signal uniformity with low noise. The 90D and R5 are currently my main cameras for astro. I will not buy the R7 II until I see

That sensor in the R7 is the single biggest reason I won't buy that body. The problem is that Canon wanted to throw a completely stupid resolution in that body to separate it from the lower end models in a spec sheet, and all it does is cripple the body. The pixels are so tiny that they don't reliab

well im not really looking for a crop sensor camera so R7 goes out the window, I was looking at the R5 but for this kind of money i would really like to have precapture ngl the R6 mark II as you said has 24MP sensor so this is why I was looking at R6 mark III more and im strongly considering it tho

The lens I think is the best comparison is the Tamron 28-75, which is 25% cheaper, and has 10mm more on the long end. OP could buy the Nikon Z5ii or Sony a7iii, both with the Tamron 28-75 f/2.8 G2, and still come out with a bit of money on top, as opposed to buying the R7 and 17-40. The Sigma is the

Just not true, no amount of tech can really make up for the size advantage So you feel the full frame 1Ds Mk II from 2004 is better at 6400 ISO than the APS-C R7? The Z5 II is 1 year old (2025) and was "build around a new sensor" source. The R7 was released in 2022. Also most people on the internet

And there’s the elephant in the room. The sensor has reached its limit, you can’t go higher than 25MP in a M4/3 sensor … This is of course not true at all. State of the art is mobile phone sensors and they are much ahead of the "big sensors". If you were to take for example this sensor and even if y
