Some may disagree (and I can respect that) but I think I already got my 35/2 GM in the Sony 24/1.4GM in crop mode on the R73. Yes, it’s only 18.5 megapixels, but 99.9999% of the time that’s plenty of resolution for my needs, even if I have to crop some. So for me, when Sony invented the 24GM, they threw in a 35/2 GM for free. Of course, others may have different needs.
Yes, you get 18.5 megapixels, but you also get a stop less dynamic range at base ISO and importantly you lose a bit over a stop of high ISO capability when the light is low. So, you have a 37mm f/2.2 lens when you crop the 24 GM, and a little over a half stop less light than a 35 f/1.8, so if the 35 f/1.8 is pretty good wide open it should have a distinct advantage not only in resolution but in the ability to shoot in low light.
Obviously we will see. But I'm not so sure it will have a "distinct" advantage in IQ since it appears it may not even be a G lens let alone GM. The 24GM will only get better for me with the next higher MP sensors. As others have mentioned 36mm at 18mp is actually pretty darn good already. I'm plenty happy to give up a half stop for the benefit of having 2 lenses in one personally
Like I said above for me the issue is not resolution, it is the loss in dynamic range and particularly the loss in high ISO capability. That won't get better with the next higher MP sensors. We will of course see about the optical performance, but I would hope that this Sony 35 f/1.8 would at least compete with the Nikon 35 f/1.8S and the Canon RF 35 f/1.8 both of which are very nice lenses even though they are modestly priced. People will of course differ on whether that half stop loss in low light is something that matters for their shooting. It does for mine and it will continue to do so even with the next higher MP sensors, but YMMV and it seems it likely does.
I remember people saying the same things about the 36mp R. And interestingly Sony gave us more MP and better performance. We will see though. Either way the performance of these sensors is so good now the splitting hair thing is getting silly. I'd still rather carry 1 lens vs 2.
We pretty much know how the next round of higher MP sensors from Sony will perform. It is likely to be based on 3.72 micron sensor (going 60 MP in FF 35mm) that we see in the 26 MP APS-C sensor from Sony and the 100 MP 44 X 33 sensor that Sony makes that recently came out in the Fuji GFX 100. We will get more resolution with this sensor and it should be a great sensor, but we shouldn't expect much improvement in high ISO capability. Increasing resolution typically does not lead to higher ISO capability.
