Thanks John, but I'm looking to use ring flash in portraits. I never used such lighting so don't know if macro ring flash can be use for it. I just found at ebay few of these. Price around that what you've paid. It looks like no point in making ring flash due price of it
Did anybody used ring flash for portraits?

Hello everybody.

I wonder if there is any ring flash for Pentax's flash guns or maybe you got some homemade projects? I checked RayFlash and they do rings for Nikon and Canon only. Unless they'll fit to Pentax after little tuning
As we know Pentax has own ring flashes but is there any difference between big RayFlash and Macro rign flash?

hello guys, there is automotive show in Worcester on 21st of May, anybody up to that? Mainly High Street full of local car dealerships but local Racecourse will be packed with vintage cars from West Midlands. Regarding to local newspaper oldest car is 1920, sounds good.

hi, as in title i'm looking for some cheap flash triggers. Basically i'll need one trigger and reciever. If you got any and not using i'll be happy to buy it. I know that i could buy off ebay but forum first thanks

John I know date of it, but that shows how many years ago Pentax wanted produce FF Unless I can't read and understand what says in article

Regarding to full frame DSLR - link unless somebody added that and I just missed it, then sorry

John here's link watch video at 3:15, guy says Pentax, but on website says C,N, and Sigma. Not that I'm willing to buy this monster, just curious about it.
Regarding to topic it is shame that Sigma has some nice lenses for C and N only:/ Specially the older models(like 70-210/2..

If you go to eye.fi website and pick SD card that you are after click to requirements and you can check compatibility with K7, Kx, K10, K20 and compact cameras. There is one "but", it looks that K7 and Kx been used for test. K20 and K10 shows:

known issues? The Pentax K20D is not compatible with Eye-Fi Classic SD Cards.

I hope that help. Regarding to other members it seems that EyeFi works with K20D

Not that I'm interested with buying this lens but regarding to Sigma's website they have little mess there. I have been checking 800/5.6 and info card says: Sigma, Canon, Nikon, but I've watched video (which is really funny) and guy saying that lens comes with Pentax and other mounts too.
I'm confused.

I'll be happy if someone can confirm that V5s or V4s works with 500ftz Unless RT's are good too.
I'm sure that V5s work fine with any studio flashes?
