Grzegorz, you have specks of dust/dirt on your sensor. Nothing to worry about. This happens alot when we change lenses and dust comes inside the camera. Buy yourself a "rocket cleaner pump" (a little blower pump, shaped like a rocket) and you should be able to get rid of the dust from the sensor. If specks are stuck on the surface, then you will have to do a wet/dry cleaning of your sensor with special cleaning kits. If you have worries about that, pentax service can do that for you.

I have a set of 4-channel Phottix triggers (1 transmitter + 3 recievers). They cost me arround 35 €. They work consistently and have a good working range (cca 80 m).

forgot to mention, PM sent last night

Oh I see, thank you for clearing that for me.

Hello! I currently own a Sigma ef 530 super flashgun and a couple of older ones. I want to buy a second P-TTL AF flashgun, so am considering buying an older used one. Does anyone here have any experience with Pentax AF500FTZ? They seem to go at a good price...

I appreciate your help!

Cheers, Luka

my vote would go for sigma 10-20/4-5.6 It's a lovely lens. But, SRS got 8-16 at a very tempting price, so you should keep that in mind

Most used: FA28/2.8
Least used: Sigma 17-70/2.8

Now, don't get me wrong. Sigma is a lovely lens, but since I have a couple of pentax primes covering from 28 to 50 mm, I rarely use it.

I recently bought Micnova MQ - NS2 neckstrap with connecting clips. It is very comfortable and long enough to carry the camera comfortly over the shoulder. I was just constantly feeling insecure with those clips when I was carrying K-5 with grip, flashgun and sigma 70-200, so I superglued them together. I know it's unlikely to brake, but I don't use the clips anyway so no harm done.

I have the early F4-5.6 version. It's a superb lens to use for creative perspective work and landscapes.
