Hello! So I recently just bought a Canon 5D mark IV and I currently use the lens that is 100mm-400mm, and it just doesn't seem that it goes as far as I would like. I am super interested in the refurbished RF600mm F11 IS STM lens. Although I know I have a EF & DSLR camera, I was wondering if there was a way or an adapter that would connect an EF & mirrorless lens to mine. Or if I would have to get a whole new camera for a farther mm lens. Thank you in advanced.
Solved! Go to Solution.

As mentioned by Ricky (rs-eos), either of the 150-600's would be a good choice. I have very little need for that focal range, so it's my preference not to invest in those. I do, or did, however use the EOS 5D mark IV with the EF 100-400mm f/4-5.6L IS USM and chose the EF 1.4X III extender for when I knew I was going to need a little extra FL. Nothing in particular against either of the 150-600's, it's just my preference to stay with "L" glass and Canon gear.
I've attached some images taken with the EOS 5D mark IV, EF 100-400mm f/4-5.6L IS USM, and EF 1.4X III Extender. Your mileage may vary with this combo as lighting is crucial with these extenders. All have been cropped 50% with light editing in DPP 4.

Osprey. These are fairly large raptors and a bit bigger than hawks.

andrea3232: "I keep my shutter speed fairly low and my ISO pretty high, but sometimes the quality isn’t all that great."
Welcome to the club! 🙂 We've all been there! Choosing the best shooting location, a camera with lower noise plus a wider dynamic range (allowing higher ISOs), and faster glass which usually means more $$$ are the usual physics-limited solutions. Unfortunately, low shutter speeds and fast sports action often don't mix very well.
One strategy I've found to help a little (possibly allowing a 1.3 to 2.0 stop increase in shutter speed) is to push the ISO to somewhat more than you'd prefer based on image noise levels, and then to greatly reduce the noise in post using a high-performance AI-based noise reduction application. I tend to prefer Topaz DeNoise AI which seems to work well with R5 images, although DXO NoNoise AI (which I have not tried) also has it's followers. Both seem to be significantly better than Lightroom Noise Reduction for preserving image detail while greatly reducing visible noise.
