There seems to be VERY limited info about Elinchrom here on Pentaxforums. I think they could be well overlooked and should be considered considering the value for money and build quality. They seem to be perfect for the Pentax buyer who probably came to Pentax for the value for money in the first place!
I own the Dlite 4it kit, and 3 of the universal receivers for use with my AF540FGZ's and have been very very happy.
Disclaimer:
If you like auto modes, go elsewhere for a flash triggering system. I shoot manual with my K5 and strobes 100% of the time. I don't like having the system make decisions for me, because often it does not do what I want it to do. The Elinchrom system is perfect because its not brand specific, therefore making everything manual!
Elinchrom is a Swiss company that builds professional grade lighting products, and for a pretty nice value for the money. The systems are easy to setup, durable, and have quite a few features. Here I will explain on why I decided to go with Elinchrom over the others.
The main thing is the fact that Elinchrom not only have a wireless triggering system that works with all of their studio lights, but they also have universal adapters to use for any other flash system out there. This spawned the thought... how awesome will it be to trigger my Pentax flash system AND my Elinchrom studio lights without worrying about stuff like light sensors/triggers and setting up preflashes and other things, just one wireless remote that does it all.
Since Elinchrom is not brand loyal, it loves all brands (aside from Sony) equally, everything only works in full manual operation. But that's fine because full manual is the only way I like to shoot. I don't have to worry about the camera or the flashguns making stupid decisions. I can control everything and make my photos. It takes less time too, because I don't have to play with exposure compensation when something comes out wrong.
So how does this all work?
First off, I went out and bought the Elinchrom Dlite IT 4 kit. This is a 2 studio strobe 400w lighting kit. It comes with carrying cases, a beauty dish, Manfrotto stands, wireless remote, and 2 softboxes. A very nice kit for $850 on sale (usually around $1000). It was also available locally, which is the only way I like to shop. Support your local businessmen whenever possible.
Secondly, you can get universal triggers that will work with any other flash system be it studio lighting or flashguns.
Third, the quality is fantastic. Not just the materials but the design of the products. They are simple and easy to use, yet offer plenty of features for the price point. I also think they are a good looking piece of kit.
The Universal receiver, is a pro and a con. Most other systems (Cactus, Promaster, Pocketwizard) use a hot shoe receiver. These can be nice because your flash mounts right into them and then onto the stand/bracket and your good to go. Elinchrom elected to go with a small radio pack that hangs off your light stand using a strap. A cable then runs to the flashgun or studio light to control it. Only manual control here, no PTT-L or auto modes, just the way I like it!
The problem with Pentax is that stupid proprietary sync socket. There is no way to use the sync port on the Pentax flashgun with your average remote system, it is really annoying, but can be fixed for around $20 using a Hana hot shoe adapter.
These things are great, they are small and have a small PC sync socket on them. The Elinchrom receiver plugs right in, and triggers the center pin. No problem! Just a problem trying to find the buggers.
With the adapted Pentax flashguns you can now use the Universal receivers and any Elinchrom studio flash unit right off your one transmitter. And if you opt for the RX series strobes and transmitter you can even control the flash and modeling light outputs right from the transmitter without having to go to each individual head! its really is a genius system.
I know use 3 flashguns and 2 studio strobes with this system. I can use my AF540FGZ's out in the field without having to worry about a different system (Pocketwizard or Cactus), and then come back to the studio and continue shooting without having to change any settings.
The system is compact, light weight, and well priced.
