Hey guys i was a walking the streets 3 Days ago just with my Nifty Fifty (super lightweight setup) getting street shots on my new A7RII cheap lens i know but always gives fun results.

I always noticed on a APS-C crop if the subject is 2-3 meters away the lens tends to give this noticeable less bokeh skew effects on the edges of the frame (usually pretty nice)

Check the edges very slight skew effect on my canon 60D APS-C crop.

But when in full frame mode this happens.

Check this result out. Shot with the A7RII full frame mode (middle of the frame is always out of focus but the edges are not)

Whats this called? and would you reckon the newer the 50mm f1.8 STM could fix this? It has much sharper edges but not sur eif that's the problem. I intend to get an expensive 50mm but i love the light weight feeling and focus of this lens. Guess the issue is that the glass isn't covering the full sensor.

Well, you can consider 'nifty' to be 'fine', 'attractive' or 'smart'. And the 50mm f/1.8 is very attractive, because it offers fine quality for very little money. Which could be considered a smart buy. Nobody is claiming optical perfection from it. Just that getting it is a good deal. I suggest we keep it around a little longer!

Then I shall call my Ac-160 my "Manny Panny"… and my 7100 my "hikon' Nikon"… and my RB my "Pooniya Mamiya"… I need to think up more rhymes and start labeling everything… this may take some time...
