After many years of using Nikon, Leica, Pentax, Konica & few others, I jumped into the 90D not really knowing what to expect, I started off with the 24mm Basic Pancake & the 18-135 IS Zoom. Initially I was very disappointed, lots of mushy images & many out of Focus. Spent hours adjusting and recalibrating.. No Joy.. I was about to trade it in and start again!.. Woke up the other morning, thought, hang on, the Tiffin UV Filters might be the cause.. Removed them, oh what difference, recalibrated the Settings (Menu) - Now, I am more than happy with the results.. In fact I just ordered the EF 70-200mm f/4L IS II USM Lens, and of course B+W XS-Pro Clear MRC-Nano 007 Filters for all my Canon Lenses.. Whilst it's hard to say without technical backup, the 90D images are now very close to some of the Leica images in my library.. My photographic motto" Step Back & Take a Little Care.. L
