Hi,
I have a seatool housing/Canon xti and an Inon D-2000 strobe. What would be the widest lens I could use with one strobe? I am currently using my 60mm but would like to go alittle wider without adding a second strobe. I am hoping Seatool will make a port for my Sigma 17-70-darn....

Thanks,
Wendy

Although this figure was not put together to illustrate this point, these photos were both taken with the Tokina 10-17mm with a single strobe. There are few lenses wider than that.

a) was with a Subtronic Alpha and b) was with a single INON Z240 (which has more power than the D2000, but not more coverage AFAIK):



Although a well aimed single strobe works for this type of subject, a pair of strobes would usually be a better choice.

To get an extra 10°, try using the Inon 0.5 diffuser. It also softens the light pattern.

Alex,
Would you not recommend using the d-2000 alone? I do have the canon kit lens (17-55mm) which fits the seatool port but have never tried that lens underwater. Umm, that would give me more width but I am unsure of the quality with that lens underwater.
