RF 600MM F11 Advice

Cantrell

All,

Asking for advice on the above lens. I have a EOS R10 and have been looking for a longer focal length lens than the RF 100-400MM lens that I have. I have an opportunity of buying a RF 600 MM F11 IS STM lens that has had very little use. The only prime lens that I have is a Sigma 500 MM lens. I have very little experience using prime lenses. I would be using this lens at the beach to shoot pictures of birds. Is this lens worth purchasing? Thanks in advance for your response.

Alex,

Thank you for your comments. In my original post I put 500MM. It should have been 50MM. I have very little experience with a prime lens.

"Sigma 500 MM lens."

What Sigma lens do you have from Sigma that is a 500mm tele? Sigma made an excellent 500mm f4 but it is very expensive. If you have one you are lucky indeed.

"I have very little experience using prime lenses."

There isn't any difference in using a prime except you can't zoom. Today (subject to change as new lenses come out all the time) still my best recommendation for this type lens is the Tamron SP 150-600mm f/5-6.3 Di VC USD G2.

ebiggs1,

I missed up on my original post. I have a Sigma 50MM lens. I realize a huge difference in focal length. The Sigma 50mm F1.4 DG. 

Thank you for your comment. I need to quit posting late at night so I do not make these kind of mistakes. My brain moves faster than my fingers.

OK that clears that up. The big Sigma 500mm f4 lens is a fantastic lens one to drool over for sure. But the Sigma 50mm f1.4 Art is also a fantastic lens. Perhaps the sharpest, at least 50mil, made or ever made. Not to belabor the topic but the Sigma 35mm f1.4 Art is the sharpest lens made, IMHO, of course. And in my job and now my hobby there have been lots and lots of lenses. Hundreds!

For you, I still suggest you check out the big Tammy zoom. Make sure it is the G2 model because the first model isn't all that good. Its OK but the G2 is in another class in several specs.
