hi erika,
i am using the canon eos 30D in the INON X2 housing ... with 45degree viewfinder optical TTL and two inon strobes. and with the INON Wetlens.
i am very happy with the optical ttl and the viewfinder. both work very good. it is really a very reliable system and works just as fine as normal ttl. just it cannot fail
so the answer is YES. it works very good with inon strobes.
the viewfinder also is very good ... you can read that anywhere in the internet ... probably thats also the reason, that many housing manufacturers are offering it now eith their housings (i think i’ve even seen it custom made on a sea&sea;).
the wetlens also works very good for a simple wetlens. it is not as sharp in the corners as the acromatic woody diopter for example. but still quite good. and much cheaper.
if you want to see some images, you can check my websites. all of the supermakros are taken with the inon wetlens. all pictures with the 45dergree viewfinder. and all images exept the wide with optical ttl. the wideangle is manual strobe.
greets, serge
