Hi - I’m new to this forum. Looking for feedback regarding an issue. I use a 7D II w 100-400 II sometimes with 1.4x tele to take pictures of Bald eagles. Unfortunately, I have to heavily crop to get the reach I want, but end up with a low pixel count/sharpness issues. Do you guys have any recommendations?.
BTW – I could always spend a bunch and get a different lens, but Canon 600 is too expensive and I believe Tamron or Sigma reduces sharpness. One thought I have is would a Canon 5DSR / 100-400 II w /wo 1.4 tele be better, i.e. overcome the low pixel count after cropping while helping with sharpness?
