Apart from the higher price, there seems to be no more disadvantage with the higher resolution sensor. However, I'm a bit doubtful about the crop-ability. To get the full benefit of the 61MP sensor, you need the best glass (tend to be heavy), shoot it at the optimal aperture (which may not be what you want for DOF, say for landscape), ensure no camera movement (tripod), shoot at the base ISO to minimize losing resolution due to noise, and ensure high enough shutter speed to freeze any subject movement (which may require higher ISO which means noise that reduces resolution). All these tend to reduce mobility of the photographer which seems to be against the idea of shooting with a compact camera such as the A7Cs. If your lens, shooting discipline, shooting parameters, and shooting environment do not meet the highest standard, you may not get the full 61MP resolution. Then you think you are cropping a 61MP image, but actually you are cropping an image with a much lower resolution. Or you think you have paid for a 61MP camera, but you actually get a camera with much lower resolution....Show more →
I think being able to crop or shoot it with a prime but using it as two different lenses is a nice thing to have but not really a game changer, I think.
I think we might have very different tolerances to image quality, but still, I've been for two weeks shooting in various light scenarios, including VERY low light situations, and getting pretty sharp handheld results even in, as I have just tested outside at night, an almost pitch black scene. I leave auto iso maxing out at 12800, but for scenes I want to ensure I'll have a bit more depth I'll either set iso to 6400 or 3200 to keep noise in control.
About lenses... the classic ït depends". I've been using the 20-40/2.8 Tamron which is not the best optically but it's pretty sharp even wide open, so I don't think it's necessarily the case of needing a big GM lens to perceive the resolution advantage.
There are some pretty good compact primes that I quite enjoy shooting with that balance so nicely on the A7C body type and would be very good options. I think the most obvious one would be the FE 35/1.8 - I preferred it over the 35/1.4 being much more compact and lighter, and honestly I personally didn't perceive a significant difference between the two to go for the GM. With the 35/1.8 you get as a bonus a 24mp 50mm-ish lens. Another good option which I think can be even more useful is the FE 28.2, a lens that I think is pretty great, have served me well and with the crop it becomes a 24mp 40mm, a FOV I quite enjoy shooting with. It's pretty tiny and very light. Not the sharpest nor the fastest AF but still it should be a good short trip combo, or even as for casual day strolls. The 20/1.8 I think is a better lens overall but it's considerably bigger and heavier (same size as the 20-40/2.8, so between the two it usually makes more sense to bring the zoom). Finally, the FE 55/1.8 which is an older lens but it checks out. Yes, other 50mm launched more recently are optically better but I still quite love what this lens brings to the table. Its only downside to me is the minimum close focus which is not as near as I would like to.
