Re: Lack of sharpness at f1.8 on Canon 50mm STM

I'm surprised to hear folks say it is unsharp wide open. It's supposed to be superior to the older nifty fifty's and they were considered pretty sharp from wide open.

I have this lens but unfortunately no wide open shots thus far. I think a little softness or glow is nice with portraiture and flowers etc. I would be surprised if it wasn't sharp enough by F2.

If you want biting sharpness from wide open then that only usually occurs with more recent designs. My Carl Zeiss Planer 50/1.4 ZE has a little glow wide open but that is part of its charm. It not only looks more natural but it gives a creamier look to oof areas..

You've now got me wanting to test the STM lens wide open just to see if my copy is soft!
