EF lens compatibility with EOS R7

[Nappert]

Newbies here.  We're wondering if we can get my daughter's Rebel T1i lenses (EFS 55-250; EF 50mm; and EFS 18-55) to fit/adapt to our new EOS 7. Thank you for any help.

Greetings,

You also aren't able to mark a question as answered in someone else's thread...please consider this for future.  

There are not huge differences between the two lenses optically.  The differences are primarily in design and construction.

However, since lenses are the real investment in photography, I'd suggest sticking with the RF-S 18-150 for the R7.  It doesn't require an adapter.  It's will be supported and serviceable for longer.  The performance between the two is almost negligible with the majority of differences being mostly design and construction as I mentioned.  One's a little lighter and can focus a little more closely, etc.  I'd recommend using the 18-150 primarily for its longevity.  You can sell the 135 with the 7D.  I did own the 18-135 about 7 yrs ago.  It was a nice kit lens and spent a good deal of time on my T6s.  Since you have the R7, I'd use the native glass designed for it.🙂
