I always use an IR transmitter, which is the same as using the camera flash but doesn't add to the exposure.

I never use cables, which can be tripped over so easily.

Using wireless triggering is better than cables and certainly the flash goes off every time.

I really would not worry about it.

Very simple, Stefan.

It took about 10 minutes from opening the bag to being up and running for the first time.

Compared to some studio flash I've used these are quite elegant in their design.

You do need to enable use of aperture ring even though there is no aperture ring - it has no electrical contacts.

However, the one I tried tended to over-expose as well, so that might be normal for these. I would just dial in some exposure compensation.

I feel able to comment on this now I have had a proper look at the EXD200 kit I have just bought.

It is well made, but not heavy duty, and with care I expect it to be fine for the intended purpose - a compact fairly portable kit in a handy carry bag.

It is much better than the cheaper EXD150.

There is one very nice feature - the heads can be set to fire using an IR trigger or the camera built in flash, but will fire on the first, second or third flash as desired. This means that the pre-flash does not upset things.

The output is good enough for portraits in domestic or small studio settings. The stands are very well designed and operate smoothly. Everything fits together well.

At £298 "thumbs up" from me.

I don't see anything inherently illogical here as we are discussing two entirely different lenses.

Gwyn finds her Tamtron 28-300mm lens not up to scratch on the K20D but fine on lower resolution sensors. The implication is that the lens does not have sufficient resolution for the K20D sensor and is a poor match for it.

Sue finds the Pentax 18-250mm lens fine on her K20D and she is producing some pretty amazing shots with it. The SMC coating does mean the colour is consistent with her 50mm and 100mm Macro Pentax lenses, which helps, but the Tamron version may well give otherwise similar results.

Hope that helps!

Sue currently uses the Pentax 18-250mm on her K20D.

Can I just repeat from the above the critical point - use Photo Mount (red tin) as mentioned and not Spray Mount (blue tin) otherwise your prints will embarassingly peel off whilst the judge looks dismally at a blank piece of mounting board....

I've watched it happen.

The answer to your query is that ex-Pentax users are welcome, but they should remember that this is a Pentax User forum. The section you quote does not extend to slagging off Pentax and saying how much better some other marque is.

If anyone who has jumped ship doesn't want to restrict themselves to this courtesy to our Pentax members, then there are other forums to satisfy their needs, and the obvious one is ePHOTOzine. EPZ is not marque-specific and has an active and varied membership.

I hope that this clarifies the Forum Policy. It's a matter of common sense and courtesy.

Maybe the difference in resolution of the two sensors. The K20D did after all demand a new version of the kit lens to take advantage if its higher pixel count.

Tel, you know as well as I do that this is a Pentax forum and you also know the trouble it potentially causes when it degenerates into comparisons with other makes.

A couple of members might have been overstepping the mark just recently, and we don't want the forum overwhelmed with discussion about other marques. I'm here to help keep it all on track, and that is what I shall do.

This is nothing to do with discussions about photography in general which are always, demonstrably, welcome. And no, we can't discuss everything we like because ultimately that is anarchy, not freedom.
