WOW Neuro..I have not noticed any vignetting with my 77mm F-Pro..but I will take you word for it and give a closer look the next time I shoot....is the vignetting more at a certain focal length of the lens?
As I stated in the description in the other thread, I have to work to bring it out. I had been using an F-Pro as well, and not noticed the vignetting in real-world shots. Well, let me rephrase - I did notice vignetting wide open, but the lens has a fair bit of native vignetting, and it seems the F-Pro makes it very slightly worse. But the thread made me check. The OP in that thread mentioned 100mm, so that's where I tested.
Good to know...so what you are saying is that if I shot a white background @100mm zoom...only @f/2.8 only and did a comparison ...if I put on my super vignette peeper glasses I might see a smidgen more vignetting??? LOL!...but...I didn't know!..I am telling U...I just didn't KNOW!
I do not doubt you for a second that you are correct...and if I knew before hand I would have spent the additional funds and purchased the XS..but I will just leave the F-Pro on there..although..NOW you have ruined it for me! LOL! Thanks....
Hmmmmmm...will I be thinking about this before I go to sleep tonight....hmmmmmmm
