I picked up a couple of primes and was surprised how bad the images look wide open. One is a pawn shop special - an "Access" P-MC WIDE-AUTO MACRO 28mm f/2.8, and the other is a Sigma 30mm f/1.4 EX DC (HSM, yeah right). The Sigma is a refurb from the Sigma outlet store, and the other from a local pawn shop.
Even my 18-135 WR is a bit soft & glow-y wide open, but not nearly as bad as these third-party primes.
By the way, this 28mm lens is fantastic close-up @ f/8! Anyway ... these images were show in RAW and processed in Lightroom with sharpening and clarity added, and chromatic aberration removed. THESE ARE PROCESSED IMAGES, not straight out of the camera. Why? Because this is how bad the look even with processing!

I'm surprised to be seeing this glow and smeared detail in all my lenses (to repeat, my 18-135 WR does it a bit, but not this bad). This has me wondering if I have a camera problem. Thoughts?
