Pentax 55-300mm f/4.5-6.3 da Plm Wr
The lens is excellent and works superbly on my K3 since the update. No idea if technically or commercially they can go back further to include the K5. My PLM purchase was in the Amazon sale at £250 just days after the firmware fix. It was a downsize for me from a 300 F4 star for lighter more ...

Pentax 55-300mm f/4.5-6.3 da Plm Wr
I find that with the 50% greater resolution and no moire filter everything is seen in much more detail including of course sensor noise. How much sharpening/ contrast you apply can have effect too. i reckon 1600 ISO on K3 similar to 3200 on my old K5 for High ISO noise. I have auto noise...

D FA★50mmF1.4
It's a beast of a thing for sure. I must admit to lamenting the loss of the Pentax way with regards to size and discretion with the new D FA's - but the market led by the 'typical internet expert' is demanding sharpness over all else which means that glass and size are thrown at the problem ala Zeis...

Macro but which one.
I have had them all and they are all good, to be honest I have never come across a bad macro lens. I kept the Pentax in the end purely because it's made by Pentax and it's a WR lens but I also have a old manual focus Vivitar S1 105mm f2.5 .

Macro but which one.
I have the Pentax 100WR and used to own the Sigma 105 DG EX. I sold the Sigma because I didn't need two macro lenses. However, it all depends on what you intend to use the lens for, is it just for macro work or do you intend other uses? The reason I ask is because the Sigma has a bit of an ace up...

Macro but which one.
Just to stir the pot a bit, back in the day when money was very tight (70s) I used a reversing ring on a Pentax, model lost in the mists of time, I guess this set-up would still work on modern lens?

Macro but which one.
I use a Tamron manual focus 90mm f.2.8. and it is superb. I had the Pentax DFA 100mm macro and found the build quality a bit iffy it would not focus with a ring flash on it due to the quick shift clutch,decent images though.Just frustrating to use. Tamron

Macro but which one.
if you have the "Catch in Focus" facility( which is useful for Macro) in your model's menu and wish to use it then you need a Macro lens that can be switched to manual focus. as far as i know you cannot do this with the Pentax, i know you can on the Sigma and think you can on the Tamron

...but I also have a old manual focus Vivitar S1 105mm f2.5 . this is the sharpest lens I got, sharper than the 50mm FA 1.4

Reversing rings work well, but are a bit awkward as you lose the aperture contacts. I was lucky enough to find a set of extension tubes second hand that have all the correct electrical contacts for the aperture, these work brilliantly. Also, you may recall threads on here a few years back about bu...

Macro but which one.
One thing no one seems to have mentioned when talking about all this expensive and fancy glass is the questsion of auto focus. It's a pesky nuisance, especially when you want the focus point exactly "there" to optimise the DoF, for example. Manuals are much better and you can use catch in focus and ...

Help needed - Long Lens
I've found the new 55 300 PLM excellent on my K3. Not been to a race meet with it yet though. It replaced a 300 F4 star and tele adapter. I've not regretted it so far.It does let in less light BUT it doesn't hunt and is very quick to focus.

Wide Angle lens for Building & Architecture Photography.
I personally have the 15-30 but thats A: Really expensive and B: I only have it because I have the K1 and need a full frame lens, its excellent though! On the APS-C options I'd normally suggest a Tokina 11-16 but I don't believe thats available in a Pentax Mount.... I briefly owned a Pentax 12-...

The Samyung 14mm F2.8 is pretty good and well within your budget, it's of course manual focus only, I've not had mine long and don't think I've got the best from it yet, down to me and not the lens.
