I remember seeing a specific post here regarding this lens, but I couldn’t find it so I thought I would give a couple thoughts as to why I won’t be keeping this lens.

I bought the lens due to its size, macro capabilities, and the extra 100mm reach over my 70-200. Its more compact and fits well within my walk around bag (Domke).

After trying it out, I can say that it does deliver some great macro capabilities which wound up being my favorite types of shots with that lens.

It also does deliver sharp images even at the corners with text and patterns retaining crisp detail.

Finally, the image quality delivered as expected for a G series lens.

If you’re looking for a lens that can be a good jack of all trades, this isn’t a bad choice.

That being said...
Image quality between 200-300 was ok to good but sharp detail seems to fall short for anyone who is a pixel peeper.

Second, the lens does a fair amount of hunting in decent light. It works well in bright daylight.

Third (and most important for me), out of all the pictures that I shot there seemed to be very few that had that wow feeling. The look that my 70-200 delivers with the same settings just gives me that extra richness in each image that I didn’t see with the 70-300.

While I could take the shots into photoshop and deliver a stunning final product, I feel that I can do pretty much the same thing almost right out of the camera with my 70-200.

This is just my 2 cents of course. The 70-300 is a great option from Sony. I just wanted it to be a unicorn! Lol!
