Pentax Ring Macro Light

I am looking at your on-line catalog to buy a Macro Light Ring for my Pentax 100mm macro lens. Pentax's own ring light is very expensive. I see a number of cheaper ring lights for other camera brands, but they do not say they will work for a Pentax lens.

If the lens thread is 49mm and you have a hot shoe, does the brand name matter? Won't a ring light that fits a 49mm thread work on any camera? If not, what ring lights that you carry will work for the my SMC Pentax-D FA 100mm F2.8 Macro WR?

Any Ring flash with a 49mm filter thread adapter ring will fit. However, if you want TTL flash dedication, only a Pentax or supported Pentax flash will work. The other alternative is to use an LED light which will work with your camera's internal meter.

The Sigma EM-140 DG Ring Flash is ideal for photographing subjects in fine detail - close-up photography - and is extremely effective for scientific and medical applications.
Dual flash tubes can fire simultaneously or separately. Using only one flashtube creates modeling, which can give a three-dimensional feeling to the subject. The Modeling Flash function makes it possible to check for reflections and shadows before actually taking the flash picture.

The Digi-Slave L-Ring Ultra II is more powerful and more versatile than the original Ultra LED ring light, and is ideal for macro photography. Equipped with 24 oversized, super-bright white LEDs, it features a variable-power dial to quickly and easily optimize the light output. A larger inner diameter makes the Ultra II perfect no matter the lens size of your digital camera. It can accommodate up to a 58mm filter size lens.
