dome recommendations d810 ikelite sigma 15 mm

thanks,

wetpixel experts have convinced me to order the sigma over tokina fisheye. now i am stressing over the best dome. apparently there is a unique issue with ikelite and all of their domes even 8 in with this housing lens combo that there is a small amt of vignettign with some camera bodies and not others. even ike spreadsheet says it will vignette with some bodies. some say it is the shade which can be shaved but most say it is the port body as the sigma lens is so short. i am considering precision 5 in dome instead of ike 8 in dome? or Zen 4 inch. ideally however i would like to be able to do split shots.

any suggestions for best dome port for d810 ikelite with sigma 15 mm???

thank you and i promise this will be the last inquiry for awhile.....

LOL, no worries, Ian!

Sorry if we are causing you stress though

I can't help on what domes are best for Ikelite housing but if you want to shoot split shots (or over/unders) you need the widest dome you can get/afford. It's very difficult to over/under with a 4"/100mm dome. I'd suggest 8" is the minimum. 9" even better but they come with drawbacks in terms of size for travelling and cost.

It's difficult to get over-under shots with my 170mm dome (D810, sigma 15mm) as well, so yeah, I agree with TimG. Go big
