£50? Bargain!. It might even be better than my Sigma 55-200mm. I think I might even go to Jessops tomorrow and get one! Oh the joys of LBA.....lol

True farfisa, but I would still like Pentax to produce a new 85mm, as it will still be an 85mm lens and act like an 85mm, even though the effective fov would be 127.5mm. It would just be a great Portrait lens. My 50mm is just a little too wide for head an shoulders shots, even though its efov is 75mm.
But thats me, maybe in my dream list of calling for them to be DFA, is in the hope that someday they will produce a FF DSLR. And as a plus, if it was a DFA i could still use it on my MZ-5n (even though it would not be SDM, only screw focus.)

Interesting, I have a Sigma 24-70mm F2.8 and I have the exact same problem with focusing on the K10D (focus point selected is out of focus and background is in focus)

Seems that the problem is not to do with the lenses, but the K10D itself.

I have tried the Sigma on my DS and K20D with no problems at all.

Seems that the K10d does have a focus problem from time to time, however it is only the last few months that it started occuring. I wonder if it something to do with the number of shots taken with it? I have taken 18000 so far, what has others who now have the focus problem taken with their K10D's?

There have been many issues with this lens on various forums, this link might help

I forgot about a macro! Silly Me

The same as Anvh, the DFA 100mm F2.8 Macro to be on the list please....

Have a look at the Pentax DA 55-300mm to complement your 18-55mm, SRSmicrosystems have it at £199. If your budget cannot get to that, you could always look at the Sigma 70-300mm APO or the Tamron Di 70-300mm
both are good lenses for the price. I have the non APO Sigma which is even less, yet still get some good shots with it.

With lenses, it is good to remember that when the zoom range gets larger (eg 3x, 5x 10x etc) it can have a detremental effect on the IQ that the lens can give, due to the compromises that have been made to get the range.

Have a try on the 3 mentioned, then go with the one that you feel most comfortable with

Hope this helps

I take it that you mean existing lenses, rather than "dream" lenses.

If thats that case I would probably say the following (ones in bold I already have):-

DA 10-17 Fisheye (just for being a fisheye and for the fun you can have)
DA 12-24mm (probably better than my Sigma EX 10-20 and faster)
FA 50mm F1.4 (any more reason than its the finest nifty fifty out there?)
FA* 85mm F1.4 (probably the finest Pentax lens, period. Also known as the "holy grail")
DA* 50-135mm (the best portrait zoom around, so sharp, fast, even Canikon users are impressed with the results I get from it)
FA 31mm F1.8 Limited (after the 85mm the best Pentax lens made, great for walking around, and you can just still get it - anyone give me £700 for me to buy one?)
The Limited Pancakes (21mm, 40mm, 70mm) (nice and discreet, great for travel)
FA 77mm F1.8 Limited (if I cannot have the FA*85mm, I will have this instead. Another fine Portrait lens and one of the best lenses around).
DA* 200mm F2.8 and DA*300mm F4 and DA* 60-250mm F4. (great long lenses, and far superior to my Sigma 170-500mm - For those wildlife shots)
FA* 500mm (again for wildlife, and far better than the aformentioned Sigma)

So, I have a long way to go, but if Camelot came up with a cheque, then these are what I would have.

I wish that Pentax, would produce more fast glass, even if it was to complement the slower stuff that they have. I am lucky to have some fast stuff, such as the FA50mm f1.4 (lovely lovely lovely..) M55mm f1.8 and a takumar 135mm F2.5 manual.

Not sure whether I would want the DA*55mm as I already have the fifty, I just wish that they would come out the a new 85mm with SDM, which taking the crop into account, would be the perfect portrait lens (not that my DA*50-135mm is any slouch....)

As for size, LCE in Manchester have the Nikkor 300mm F2.8 in the window at the moment, and its a monster! I can image if Pentax brought out a F2.8 version of the DA*300mm would be similar.
Mind you you can still get the FA*600mm to special order if you want and have lots of pennies going spare....

Shall we start a campaign on the Lenses we want Pentax to bring out (based on classic lenses) only this time have SDM on them too?

I will start

Dear Pentax, please bring out the following lenses ASAP:-

DFA* 85mm F1.4 SDM
DFA* 135mm F2.5 SDM
DFA 31mm F1.8 Limited SDM
DFA* 500mm F4.5 SDM
DFA* 80-200mm F2.8 SDM

Thats it (for now)

I have both the AF540FGZ and Centon FG30D. The 540, i am still learning, and the 30D is useful as a second falsh (only cost me £30 a few years back) I do like the Pentax, but still need to work out how to use it.

Fair enough Ice, I thought that is what the OP meant.
I have just looked at the K20D, which has mutliexposure, I have not used, but the DS does not have it.

I normally use Photomatix, to merge a number of Exposures to make the photo. Not used the multi exposure accordingly.
