The Pentax-F 28-105 is an awful lens so I doubt if the done up version is any better. The F 35-105, on the other hand, is an absolutely wonderful beast, although they often have damaged plastic filter rings (take the glass out of an appropriate old filter and screw the metal ring in to strengthen it - works a treat). I think the focal range of your Tamron is maybe pushing it a bit too far? Their 28-200 is an excellent performer that always goes on holiday with me. There is a Pentax version too but it's simply the same Tamron rebadged! You won't go wrong looking at the Soligor m42 lineup either - the f5.5 300mm might be manual and slow but it gives a DA* a run for its money. £30 as opposed to £900 or more? The f4.5 250mm isn't far behind it either.

Like that ?

Sun, sea, sand - everything we all want so badly!

For a kit lens, that one has to be one of the best available. The only annoyance is its vignetting at the wide end. These are super images that only add to its reputation.

It's a nice gecko too!

Picking things up as you walk around provides all manner of interesting macro work when you get home. Interesting to see that you also use a K5 for it. It's made for macro! Your use of stacking produces some really superb results.

These certainly show it off well.

That's the stuff he needed in his developing tank - refreshes the parts other beers cannot reach.

If you keep the K1 then try some of the Meyer Optik glass. Only thing to watch for is oil on the iris - it can spring blades loose if they stick together! There is certainly no need to pay big money on modern stuff. The Takumar 3.5/200 works amazingly well with it. I still use the K5 for macro because it's perfect for that job.

Simple is often better. This has a wonderful tonal range that drags you into the distance and pulls you straight back again.
