I shoot a lot of table-top and technical stuff, frequently with the 60 Micro. Lately, the small softboxes and mods are too cumbersome. So I bought a Stellar STL-80R LED ring flash. Linky: http://www.bhphotovideo.com/c/produ...TL_80R_FLASH_STL_80R_Ringlight_LED_Flash.html OK, the Stellar works, but it is disappointing. Obviously no TTL, but the "flash" power is not adjustable (although the 'modeling' power is). And the 'flash' duration is so long, that shutter speed controls exposure as it would for ambient light. No way to meter (flash meter no worky), so it trial and histogram shooting all the way. Even when I get it dialed in, the subject distance greatly affects exposure, so more trial and error. It has gotten old, although I do like the ring-flash light source for small technical subjects, and out in the lab/shop. So here is my question: What are some quality alternatives form camera mounted ring flash products, espectially TTL metered? What has worked for you?
