Will these extension tubes work with a Canon mirrorless camera (e.g., EOS R) and Tamron 90mm lens?
Asked by: William
Natively, these would only properly mount to EF/EF-S systems and lenses. However, you could use these with the EF-RF adapter, with potentially some loss of autofocus reliability.

Will this set work with Canon mirrorless (ie., EOS R body) combined with Tamron lenses?

I’m not sure William, but it looks like it won’t fit in a mirrorless EOS R because it uses a RF mount.

question

With this device, what improvement is there to the close focus ratio? Discuss the pros and cons?
Asked by: Anonymous
This is a. good little tool for the price- It has no elements so it relies on the clarity of the lens glass entirely without clarity loss. Im not sure precisely how it alters the close focus ratio in terms of a ratio, but of course it i creasess it because otherwise you wouldnt be able to focus on the object in a macro way--- if your question is, does it distort or alter the look of the focal length my answer would be no, but my experience is that it facilotates different looks with different lenses (tested 28-200 and zooms as well), my advice would be to experiment--- The only con I sont believe is any fault of the device--- that is that you generally pick/up a limited depth of field inherent to the close macro effect, which you may or may not like working with or around....
