Lens / Port choices for the Canon 5D

18 July 2007 - 07:04 PM

Hey guys,

I've been taking dry pictures with the Canon 5D using a Sigma 28-300mm lens and am pretty happy with the results. I feel ready to take the plunge and start to outfit the camera for UW photos!

I'd like to ask your opinion about lens choices for wide angle, work-horse and macro shots for this camera in particular.

I really enjoy shooting macro, but also see myself shooting reef scenes and medium-sized fish. My first trip with this camera underwater will be in Bunaken National park (combo of beautiful coral / pelagics / macro) and the Lembeh Strait (full macro) in North Sulawesi!

After a bit of reading in the forum, I think I've narrowed the lens list down to these 3 lenses, given that I will be shooting a wide spectrum of subjects / dive sites:

1. Sigma 15mm Fisheye (purely wide angle dives)

2. Sigma 50mm f2.8 EX DG macro lens (to be used as my work-horse lens but also capable of doubling up as a macro lens if a suitable subject arises!)

3. Canon 100mm USM macro lens (for purely macro dives)

I will be getting the Ikelite housing for this camera but still have to figure out if I can get away with only getting 2 ports for these 3 lenses.

I would get the "Canon specific" flat port for the 100mm Canon USM lens and the 8" domed port for the 15mm fisheye lens. However, I am not sure if I will be able to use either the 8" domed port OR the Canon-specific flat port for the Sigma 50mm macro lens (according to the specs, the 50mm would fit in the domed port but I am not sure if the images would be distorted...). Also, I am not sure about exactly how brand/lens-specific the Canon-specific flat port really is.....

Any thoughts on these lens choices and whether I would need 2 or 3 ports?

The National Geographic Society has recently published, in their magazine's April 2007 issue, a 3-part Special Report on the Global Fish Crisis, and how we can save our ocean's (rapidly dwindling) bounty.

I encourage you to read this sobering and well-illustrated report, which you can find on this link:
