Many of you suggested in a previous thread I move to a full frame camera due to lenses I already own. My current gear: Canon 20D body (Dead) Canon EF 70-200mm f/4L USM Canon EF 100mm f/2.8 Macro USM Tamron AF 28-75mm f/2.8 Canon EF 17-40mm f/4L USM Canon EF 50mm f/1.8 Canon Speedlite 420EX Are all the above lenses compatible with a full frame camera like a 6D II or would I have to lose some of them? Originally I was going to purchase 80D with Canon 18-135mm f/3.5-5.6 IS USM, but i think 18-135mm is an EF-S lens which means its not compatible with full frame cameras. Anything I buy from now on I want to make sure is compatible with full frame in case I go that route in the future. I think regardless of what I buy, I’m just going to get the body only and use my existing lenses for now. Maybe purchase one more lens fast prime or ultra wide angle lens. So I narrowed my choice between 80D and EOS 6D Mark II, What is everyones thoughts on EOS 6D Mark II and the 80D? Some have said EOS 6D Mark II is like a Full frame 80D. Better in low light, full frame, etc…The bad news is it is almost negative is almost double the price of the 80D. I have around $900 in Amazon credit plus another $1,000 I have saved up. Thanks in advance for your suggestions. The type of photography I like to shoot: portraits, night scenes, indoor, landscapes, sports(my kid's basketball/soccer games), low light and creative photography.
