Well due to an unfortunate incident with my boat I had to sell it for way less than I paid. However I'm making lemonade out of the lemon. I've now got a little cash to throw into my newfound hobby. I've been using an SP-350 housed with an FL-20 flash since I started. I've purchased a couple of different complementary strobes but the one I have now is the YS27DX.
My ONLY issue with this setup is that to fire the YS27DX I have to attach the fiber optic cable to the flat port of the FL20. This has proven to be a somewhat flawed method which has lead to numerous problems underwater with the 2nd strobe not firing. However, when I do manage to get both working correctly, I'm happy with the results.
Now on to this extra cash. I'm troubled on how to use it. Its about a $1000. Along with the value of the SP350s, 2 housings, 2 strobe housings, wet lenses and the YS-27DX used once, I think I have enough to purchase a low end DSLR (Canon xti, Olympus E510 or Nikon D80 are the 3 I'm looking at). I believe I could also find a housing of reasonable cost. If I go with this setup, its almost certain I'll end up with a cheap optical strobe or something along those lines for awhile in the beginning.
The other option is to sell a few things and purchase two really nice strobes along with the Athena or Heinrichs adapter for the SP350 and stop having to worry about lighting. I might even be able to fit a used DSLR in for topside stuff.
Nice dilemma to have as I convinced the wife it would take about a $1000 as a salve or balm to help me over the misery of losing my boat.
But here's the use model. My wife and I do some topside shooting while on hikes etc. I dive about 20-50 times a year depending upon where my job takes me. I'd call myself an opportunist because I don't really go specifically after a subject. I'm a little more than a snap happy tourist as I will take the time to shoot a subject several ways. Truth be told I'm not that good compared to most on here but I enjoy it a lot. I enjoy the SP-350 but there have been a few occasions when I yearned for something a little more. From what I've read on here the DSLR is a completely different experience. Ports, domes, dipotres, lenses etc, weight, size, all have me concerned that I might take a step back with the learning curve.
I'm sure this has been hashed over before but also any underwater input you have on the 3 cameras listed would be great. An example might be the flash sync speed...is that important?
Anyway sorry for the long read,
