Yep, you can get a wireless (i.e. radio) version for less than £20 (seen some at £9.99 on Fleabay). The key for me is that they work in any direction - you don't have to be in front of the camera (if you have a K30 which doesn't have an IR sensor on the back).I honestly don't know why anyone bothers with these

You don't need the Dongle with a Pentax and any transmitter will do. It will also work with a lead, but you need the Canon jack to jack for that.
Oh .... I didn't know that. So, if you don't need the dongle, how do you set which channel is used?You don't need the Dongle with a Pentax and any transmitter will do. It will also work with a lead, but you need the Canon jack to jack for that.
Now that this thread has reminded me - must buy one myself.

You can also change the RAW/Fx button to do something more useful - such as Optical Preview (or Exposure bracketing).

I once tested my FA 31mm against a couple of zooms including the 18 - 55 mk2 kit lens and at f5.6 there was no discernable difference in centre sharpness. A few months ago I realised that I had accumulated 7 lenses that covered the 24mm focal length (in my continuing search for the 'perfect' standard zoom) - 16-45, 16-50, 17-70, 18-55, Sigma 17-70, Sigma 24-70 and Tamron 10-24 - so I did a comparative test at f5.6. I do not have a 24mm prime so I included the DA21mm in the test. I took reasonable care - tripod, mirror up, remote release - and once again very little to choose centre frame.
Yes, that pretty much mirrors my conclusions from the limited testing I have undertaken. I'm pretty confident that, at f/5.6, a Pentax SMC M 50mm f/1.7 is more detailed than the 18-55mm mk2 kit lens, even in the centre of the frame (but not by much). At f/8 onwards, its just too close to call. I also tested the kit lens at 24mm against what I understand to be a quite highly rated Sigma 24mm f/2.8 Superwide II without drawing any firm conclusion - even at f/5.6 in the centre of the frame, the kit lens and the prime were very close. If anything, at the edges and corners, the kit lens was sharper.I once tested my FA 31mm against a couple of zooms including the 18 - 55 mk2 kit lens and at f5.6 there was no discernable difference in centre sharpness.

All the tests I've done previously, used a Pentax K200D and it may have been a limiting factor in some cases. Maybe I should have another look with the K30 I now have.

Indeed - but the question I asked was about whether the IQ of a good modern prime is better than that of the 16-45 zoom under the same conditions. Some say 'yes', some say it doesn't matter anyway (which suggests 'no')Pictures in low light without ramping up the ISO excessively, shallow DOF shots that you cannot get at f4, or when you need the fastest possible shutter speed.

But it's about much more than that anyway. The 16-45 is quite a bulky lens and f4. A prime just has a completely different feel, takes you into a different mode of viewing and you have faster options for different situations and types of image.
Yes, I understand that and it is another consideration - but I was asking about whether the primes had better IQ.But it's about much more than that anyway. The 16-45 is quite a bulky lens and f4.

Yes, that is what I meant - comparisons of photos taken with the two lenses. Tests? Why not look at pictures taken with them.
If you have samples of the same photo taken with the 16-45mm and one of the primes (sharp, in focus, same settings) that clearly shows the difference, please post them.

Just a thought - but are the 30/35/40mm primes really much better than the 16-45mm zoom at the same focal length? I haven't looked too hard, but haven't been able to locate any tests that substantiate the notion that it's worth shelling out for one.

The M version is without doubt the biggest bargain amongst Pentax lenses.
