Just a thought...what's any of that even mean? Adventurous Photographer, Writer

I've not seen anything new in the photography realm that made anything I've bought or used in the last 40 years stop working. In fact a lot of the new stuff has caused me to really appreciate my old equipment even more. Did anyone say it would make your stuff stop working? I must have missed that in the thread.

In fact a lot of the new stuff has caused me to really appreciate my old equipment even more. This is very true. All my old gear is still just as good as the day I bought it. --- But I have to admit, if I didn't already have an Eli RX600 I would think seriously about one of these just to be able to lower the power a bit more. Sometimes when I'm shooting larger aperture my RX is as low as it gets, and I have no room below ISO100 and I can't sync beyond 1/250. Yeah, I know I can use another diffusion panel in my box or clip on an ND gel, but it sure would be easier to just push a button and lower the power. Moving the box further away changes the light quality. http://www.flickr.com/photos/picturedisk/

For the ones who aren't interested in purchasing some strobes well then..... People worry about tiny variations in color temperature, which I find silly since I work in everything from 2500K to 10000K at a wedding. People worry about flash duration, they seem to care about the difference between really frickin fast and really damn frickin fast. The voltage thing's handy, except you can order ABs in any voltage, so the only real advantage is for people outside the US.

Sure the Einsteins look like good lights, but people worry too much about minor technical things when they should be working on their creativity and composition. I agree whole-heartedly! I find being creative so much more challenging than a 100 degree shift in color. Canon 1DMkIV, Canon 1DMkIII, Canon 50D

Moving the box further away changes the light quality. I'm happy with what I've got, but I have to admit, if I was assembling gear right now, I'd probably get the Einstein. The easiest thing you can do is put a ND filter on your lens. If you don't have an ND filter for your lens then use your polarizing filter or both if you want to shoot really wide apertures. No need to move the light or deal with gelling your strobes.
