I have spent two weeks taking nearly 2000 images with the new Canon R7. I have taken images in various light conditions and using two RF lenses to cover topics like birds in flight, landscapes, sunsets, waves, wakeboarding, boats etc. The two lenses I used are the RF 100-500 and the RF 14-35mm.F4. I mainly concentrated on the 100-500mm. These are my findings so far. PROS: - Fast frame rates. - Great quality images in good light conditions. - Lighter body with good grip for small to medium sized 'male' hands. - Very fast AF Tracking for birds in flight or sports action in good light. - Greater reach with APS-C sensor crop of 1.6X. - Low noise in good light conditions due to lower ISO.Read more
CONS: Loud mechanical shutter. - Lots of 'noise' in poor light conditions, due to higher ISOs. - AF Tracking slower or missed images in poor light conditions or lack of contrasting light.
- Takes time to find which AF Tracking focusing 'zones' work best for various subjects and movement.
Conclusion: I thoroughly enjoy the extra 'reach' I get and fun to use with great AF Tracking as long as you can keep ISOs to a minimum. When the tracking locks on Birds In Flight it is a joy to use.
