Ok, new here, but not to photography. Hello everyone and thanks to Luminous Landscape for providing this site all these years. I have followed it for many years.
Some or these questions I posted at another forum and the folks were great, but after months I have not yet settled on the answers.
Let me preface my post with this. Ever since the 10d first came out, I have avidly put UV filters on every one of my lenses as I took them from the box, including my RX10 iv. And I won't take them off. Just a hangup I guess..keep the lens clean, scratch free, etc.(I slipped many years ago at a waterfall and my Canon 17-40, the end of it took the brunt of a glancing blow on a rock when I went down...the UV was totally ruined, sent lens to Canon, nothing wrong with the lens..so I am a stickler about protective filters. I also know that it is one more piece of glass between sensor and subject..I am good with that.
1. Circular Polarizer. I want to go totally with Breakthrough..love their stuff. I am coming from B+W F Pro UV and the Kaseman CPL. Love Breakthrough too, BUT....BUT....last year went out west with rx10 IV...FPro UV, and Kaseman CPL. hundreds of shots, many at full 24 mm...and great shots..no vignetting. Recently got the X4 from breakthrough and put it on my Fpro and had vignetting..not a lot just a little bit in corners. Frown...Read up on it, and found there is a .4 mm less thickness with the Breakthrough UV than the BW F pro...so ordered the Breakthrough UV, hoping it would resolve the vignetting. Tried it just now and nope...still vignetting.
So...f pro and kaseman, at 24mm, no vignetting.
Breakthru with either UV has vignetting.
Breakthru is supposed to be colorless, and that is why I want so much to go to it. But I won't remove my UV protective filter.
Any thoughts? Is the color light transmission difference between the XS-Pro HTC Kaesemann Circular Polarizer ane the X4 really noticeable or is it minute? Any suggestions? Is there and even thinner UV that is good? I know the BW makes their casings wider than the threads in order to prevent vignetting.
I have scoured the internet and read review after review and still have not settled on anything.
ND's....same thing, have not tried Breakthrough, but fear the vignetting again.
Now, question on 4x6 GNDs...did a lot of research before this covid thing, as I was going to Hawaii...finally figured to get a one hard, and a set of 3 medium and 3 soft GND's. I settled on the the Haida Red Diamond as the best. Any thoughts, suggestions?
Thank you folks...Tim
