    I bought mine right as it arrived on the market and I wish I would have waited. The noise level seems to be worse on my previous cabers.

    As a professional photographer, I can appreciate the amazing IQ and features that this camera offers. 61MP is enough to print VERY large and crop at will. Then you have the Pixel Shift which is amazing for product photography as well. Really, aside from a possible 36MP version of the A9, this camera is at the top of my favorites list!

    I switched from the canon 5D/1Ds series a couple years ago to the sony a7riii and that camera was far superior at the time to anything else on the market. This camera is even better than the a7riii in terms of AF, ergonomics and speed. The only downfall is that you may notice more noise at higher iso due to the higher pixel count on the sensor, it is always a trade off. Still if you know what to expect and can control the light, you will get great results. I will also say that the high resolution demands the better quality glass as well.
