I'm attempting my first outdoor model shoot tomorrow. Never tried this before. Thought I would just ask if anyone could give me any last minute tips or recommendations, From their own experiences. Also what kind of lens choice would you recommend ?

Thanks for the replies lads.. Looks like I could be struggling

Do we have any users amongst us using the above flash. Just been reading my manual for the Pentax AF540FGZ but find it a little confusing. I was researching High speed sync. Which I understand to a point. But I would have preferred to use it in manual mode. Though it seems it can only be used in P-TTL mode. Is this correct? Also It cant be used in this mode off camera it seems. Why ? Can anyone enlighten me..? No pun intended..

There is no doubt that being right or wrong about the full frame argument. Ricoh are certainly losing market users and will never be taken seriously by professional photographers until they have one in their armoury. Anyone like me who likes to take images in low light venues without the harshness flash. Will have spent lots of money on the fastest lenses that Pentax have to offer. But when coupled to a crop sensor camera still they cannot compete with the image quality that comes from full frame. I see signs of Ricoh putting the Pentax house in order somewhat, By updating the product range. So I'l hang on a little more yet. Mainly due to the investment I have made into the system, and a little brand loyalty I seem to have unknowingly developed.

Though I find this statement tempting...

Ive never owned the Samsung version but I do own a DA 16-45. I believe they are the same, but wouldn't swear on it. What I would say is that it is a superior lens than the 18-55. The main point being that it is faster at the longer end.

Interesting use of the ND filter. Something I will surely try out.

Thanks for the replies guys. You have confirmed in all honesty what I already knew.(Except for the Aokatec trigger) But it is nice to know im on the right track. I'm not afraid of manual flash at all. Just find that when im mixing with ambient light. I find myself constantly metering. Being generally lazy I thought I could cut this down somewhat. Which was why I got the Pentax AF540. Looks like I was mistaken.

I want to experiment with P-TTL off camera. I have a Sigma 610 super and a Pentax 540. I had always been under the impression that the P-TTL system wasn't to effective and that wireless triggers were not available to suit. I have an outdoor shoot in a couple of weeks and thought If I could master the process, it would save a lot of metering time. Has anyone mastered the P-ttl system off camera and what are your views on it ? What did you use to fire the flash guns ? Do you get consistent results ?

Before anyone asks. I'm not on commission...lol The Yongnuo 560 is now pretty much obsolete. The 560ii Is manual GN58. Has a digital back panel. Support for high speedcontinuous shooting. 8fps. Power Zoom facility. The 560iii Has an in built radio receiver to work alongside the Yongnuo RF-602 or RF-603 trigger. If you want to use off camera. Both are supplied with foot and case..
