Since this is specific to Pentax I didn't place in the Flash Forum.

I would like to get a Twin or Ring macro flash for a reversed 50mm but I'm a little confused on two things.

1. How would one attach the ring
2. Would one made for other than Pentax work.

Can anyone recommend places to purchase in either Toronto or London Heathrow.

Thanks

1. i think you just hold it there with a free hand
2. if its not made for pentax it will most likely sync incorrectly - the pin configuration will probably be wrong.

3. Make a led ring light like me and robar

It has been said in another thread that "u people are frikkin geniuses". I'm not too good at that sort of thing.

What sort of results did you get with that 8 and 4 attempt.

Anyway, what do you mean you have to hold it there - doesn't it, the rign, go over the lens?

nlp,
i have a ring manual flash purchased on ebay for $30. it's great. i've used it quite a few times. with a reversed lens, nothing is going to sync correctly. what you have to do is shoot in manual ex. and figure out what the best exposure will be. here's a shot taken w/it. some kind of weird spider. you have to take a lot of test shots to see what the results are for different exposures.

oh,

forgot to say that this is a pic taken w/a reversed 50. i attach the ring light to the lens by using a rear lens cap w/a hole drilled in it an adapter ring glued to it.

Thanks Rob. Could I please be bold and ask you for an image of the setup. I'm not good at picturing things - just photographing them.

I bought one of those Halo Ring Lights, it is always on so there is no requirment for it to sync. It comes with a 52mm and a 55mm adapter. I would prefer one that was all LEDs but I am not up to building one. A fellow in Germany was thinking about making it in a kit form, circuit board housing, all you buy is the items on a list.

nlp,

sorry this took so long but here's the set up.
pic1 is the separate parts.
pic2 is the rear lens cap(w/hole) w/a 52mm ring glued to it and attached to the ring flash.
pic3 is the lens attached backward via the lens cap.
pic4 is the body cap w/49mm ring glued to it.
pic5 is pretty self explanatory.
