Using TAv mode with flash isn't good though. Often the cam will choose an ISO of something like 25600 and the pic will be blown out!!

I just phoned my local independant camera shop to enquire about the sigma and tamron lenses and the person there told me that these two macro lenses would not be suitable for a digital pentax camera when using for macro work. He said that they are full frame lenses and this would mean that I wouldn't get the same macro results on my camera.
Can anyone shed any more light on this for me please?
Check out the macro on my Smugmug below - all taken with K7/K5 and the Tamron 90. But the Sigma 105 would do the same job equally as well.

My K5 lives in TAV mode, occasionally changing to manual where there is difficult lighting
Without a doubt TAv gives you the best of most worlds and the only times I don't use it is when using P-TTL flash (in Av) or macro (MF) or MF because I know what I want and don't want any settings to change.

Monopod ...hmm now then I have never understood the concept of monopods (motor racing aside) - you pop your camera on the end of a stick which can then move in every single direction and every plane bar the vertical one. What am I missing in my belief that this makes them less than useless ?
BTW I have also tested on a monopod with SR on and SR off. Very little difference (again proving the effectiveness of a monopod) but the SR shades it.

28mm is considered the cut-off point for distortion. I use a Zeiss 28/2.8 for landscapes and stitch where necessary. Pentax's 21 Ltd has even more distortion than the 15 Ltd so is not the best lens for situations where distortion is critical.
Do note however that there are some software programs that can correct the distortion - though you will need to shoot extra wide because the correction reduces the FoV - so you could be better off with a 28mm, that does not need correcting, in the first place !
IMHO you have little choice as there is no perfect or cheap solution for what you want. A tripod and stitching where/if required solves most of your problems (except the hand-held one). The expensive solution is a FF DSLR and a 24/28mm lens (but for those $$$ you might as well use a K5 with the 15 Ltd and correct in software) !
