| p.1 #6 · p.1 #6 · Thoughts on Heliopan UV/IR Filter...Worth $300? |
Lens itself shouldnt cut out any part of light frequency.. Contrary to that, lens should at least allow to pass through as much and as even amount of each part of light frequency from visible spectrum. Which is something thats not exactly strong point of any Canon lens (or Sigma, thats usually even worse). Tho neither Nikon is perfect.
Its quite a bit of paradox, but one of lens with best color transfer is for example Samyang 85/1.4. Plus most of Leica and some modern day Zeiss are sorta ok. And if Im correct, Sony does ok job too (tho Minolta did much better).
I think that UV/IR cut filter can help, but it depends more on camera and its sensor sandwich than lens (probably cause most lens can do UV/IR pics reasonably well ).
