I had asked for opinions/feedback on how a SK35 XL would work on an IQ180. My question was answered which lead me to buy the Rodi HR40 t/s for my IQ160 as I'm not yet willing to let the IQ160 go. As good as the SK35 XL is I've found the 40 to be better. While I found I needed to use a center filter fulltime with the 35 that isn't necessary with the 40. However, there's no such thing as a free lunch. I had heard the 40 was susceptible to flare which I found out first hand today.
I was asked to share images with what might be considered extreme shifts.

Walking out to my rear yard this afternoon facing south with the sun located directly over the subject. I shot 3-rows beginning centered then moving 15mm right and left before raising the back 20mm and shooting the same sequence and finally lowering the back 15mm and doing it all over again for a total of 9-images. I didn't notice the flare until I got the files on the laptop so decided to reshoot just the center row using the Cambo Hood. No processing other than to convert into jpegs.If you have the time can you shift the 40mm out to 15 or 18mm? I curious to see if there is much sat or detail falloff and if the lens shows the hard corner vignetting aka the disk that shows up with the rod 35 23 and 28?
