The only person who is going to see that there was anything wrong with the Sony 28mm f2 would be you. You could still use it with a 24MP camera and not see the difference. See
my explanation above.
Besides, you can get an exelent copy of an older lens for half the price of the brand new Viltrox.
I have 50mp A1 and 61mp A7RV when I need to capture greater resolution and detail than 24mp.
I chose the 24mp A9III for its fast global shutter and what no other fullframe camera can do, like 120fps raw with pre-capture, 1/80,000 second shutter speed, flash sync at any speed including 1/80,000sec., no rolling shutter in either stills or video and lots more. I will use all these advanced features for my professional and personal work, shooting all subjects around the world.
I dont "blow" my money on gear, LOL. I buy the best gear I can afford to do my varied work, like buying any tool that is best suited to doing the job.
But it is just fake news and fake theory to say it makes no difference in ultimate resolution and detail to use any camera above 24mp, LOL.
With Five decades of International Award Winning photography, shooting all film and sensor sizes, and with my Master's Degree in Digital Photography, I fully know and practice the science. And I have taught it to my hundreds of photo students as a longtime Professor of Photography at a state university.
24mp may be the sweet spot for all you shoot and for many others also, but as sensor pixel quality and density increased along with modern lens resolution increasing, so has the resulting ultimate digital photography resolution and detail increased, just a fact. Not everyone wants or needs that, but my clients and I make good use of the best, when appropriate.
Maybe you eyes cant tell the difference, but these eyes of 50 years as a pro, shooting all size sensors, can easily see the differences in resolution and detail.
It is fine if you are happy using the lower resolving Sony 28mm f2 lens, help yourself, new or used. But the reality is that the Viltrox 28mm f1.8 is the one with the better image quality, the experts and testers agree with me on that, and is at a reasonable price. Viltrox lenses are incredible quality/performance/price values, just a fact.
I wont be going back to using the "decent but average" Sony 28mm f2 new or used, on any of my Sony bodies, thank you.
And IMHO the Viltrox is the one for the 33mp A7CII of the OP, and the lens to keep if the OP ever upgrades to any higher megapixel camera in the future, just a fact.
Use what you like ,what you need, what fits your photo budget, and be happy. I am not a pixel snob, but I have always made the most of all the great advances in photography, and I will continue to do so.
My solid and reasoned advice to the OP stands on the science and the facts, and also makes good financial sense going forward.
Cheers and best to you.
