Which lens for a Canon EOS 5D?

[Kraken de Mabini]

Which lens do you suggest for casual underwater photos with a Canon EOS 5D camera?

(I have the camera and housing, but no lens).

Thank you!

Hi @Kraken de Mabini  We are happy to offer suggestions, but it depends on the type of photography or subjects you wish to capture.  Also, is budget a key consideration?  
 

Please share a few more details so we can share the best suggestions.

I photo small to medium size tropical fish, and nudibranchs. 2 cm to about 25-30 cm with a Nikkor 60 micro, and wonder which is the equivalent Canon lens.  Thanks.

Are you currently on full frame or crop?

 

If you're on APS-C with a 60mm then the full frame equivalent for canon would be one of their 100mm macros. 

 

If you're currently putting the Nikon 60mm on a full frame, then the only one I can think of is the Sigma 70mm macro but I've never seen any report of it being used underwater

Your Canon 5D is an FF body with the EF mount.  Unfortunately, Canon never had a good medium macro lens similar to the Nikon 60.  There was a Canon EF 50 f/2.5 macro, but it is discontinued.  Additionally, it was a slower focus.  
 

The most popular EF uw lenses I have seen were:

 - 16-35 for wide

 - 17-40 for wide at a lower price point

 - 24-70 

 - 100 L f/2.8 macro

 - 8-15 fisheye

 - Sigma 70 macro (possibly, don’t know focus speed)

Here is an article Reef Photo published with some recommendations for the EF system.

It may also be worth while comparing against a newer body/lens as well.  Unless you specifically want FF, there are some solid APS-C body/lens combos as well.

Hi, ChipBPhoto

Thank you for the most useful information!

The 100mm macro would work nicely for your smaller subjects but you would be a bit distant for the larger subjects.  a 150mm subject you might be about 300mm away from and a 300mm subject you would be close to 900mm away.
