I did'nt want to put the OP off Anvh.......

I too are dreaming of the day of the lottery win to get hold of one of these beauties.....

Call it what you will - "Plastic Fantastic", "Pocket Rocket", "Budget Barnstormer", the DA35 F2.4 is one excellent lens. As I have said before, it's Pentax's little secret - a lens that is cheap, yet out performs lenses many times the price.

But I can understand if the DA35 Limited is more suited, if only for the build and Macro ability, or the FA35 for its aperture ring, and therefore able to be used on all Pentax film cameras (the DA's can't for this reason - My MZ-5n cannot control the aperture of my DA35)

So, it comes down to what you want to do with the lens.
If you want macro too - get the DA35 Limited
If you want to use the lens on film too - get the FA35
If neither of the above are of interest, then get the DA35 F2.4, you won't be missing anything from the image quality at all.

Another vote for the 16-45mm. On my trip to Scotland, the 16-45mm was used on just about all landscapes.

It's a tough call really. Superzooms by design are compromised in their image quality. It is better to have a number of zooms to cover the same focal range. However, they are very convenient and a DSLR with one on it are still far superior to any "Bridge" camera or compact.

Now to the Sigma, It's a non-EX model, so it is built to a budget, and the build quality can be hit or miss. But if you get a good one, then it might be just what you want.

It all depends on what you want to shoot with the lens, as both have different applications.

The 50-135 is perfect for Portraits and event photography and general telephoto work.

The 60-250 is perfect for more nature photography (albeit could be a bit longer at times), sport, and "county show" stuff, Plus general long reach images.

So, decide what style of images you take, and pick which one which is suitable, and then save up for the other one.

Hope this helps

Just to put the cat amongst the cliches.

I have the Sigma, and it is a stunner. Its not labelled DG, but is certainly an EX. Metal bodied, and contrary to John's comment about Sigma lenses, works perfectly. I got it second hand for £250 albeit 2 years ago.

In all honesty, with regard to Sigma lenses, they do work better on Pentax (the faulty one's all seem to be on Canon mount) However, it is best to go for EX lenses for better build and reliability.

3x 8GB and 2x 4GB, mainly use the 8gb as the K-5 goes throught them rather quickly, the 4gb's are normally in the backup (K20D)

I could with getting some good Sandisk 16GB cards at some point.

It was Av all the time, but mostly TAv now unless it is bright, on a tripod or shooting at F1.4 then back to Av. Oh and yes, P when I am shooting with my flashgun.

The K-5 is perfect to use with the TAv mode, you can forget whether the ISO is too high, such is the monster ISO performance

I voted maybe. I have lenses in the focal range which are probably considered "superior" in optical quality, and certainly faster.

However If there is a need to travel light and not have the need for changing lenses nor need fast F-stops, then it might be a consideration.

Send it to Pentax repair (via SRS) for an estimate.
I only say that as a friend of mine had the exact same situation with her Canon 17-40mm lens that dropped on the stone floor at Manchester cathedral with her 5D. Both went off to the repairers and both were repaired (the 17-40 had split in two like your 16-50). Both came back perfectly repaired and work wonderfully.
