sony/minolta 135/2.8 STF on pentax?
Thanks Tyr but still worth a try to see if you can mimic it with a gradient filter. It has a centre graduated filter in the middle of the lens next to the iris. Clear in the middle, darker to the edges. It is not a coated or dyed filter, but is actually shaped (negative) lens element. By making t...

Hood for DA-L Lens
The hood for the new 18-55mm WR lens won't fit. As said above, have a look on ebay. You can get something which fits pretty well (doesn't rattle or feel as though it'll fall off) for about £10. Just make sure it uses the bayonet fitting rather than screwing into the filter ring.

filter with 35mm limited?
Thanks all for your advices. I took the plunge with the 35mm limited from SRS. I think I read somewhere that you can't use the built-in hood with a filter on. Is it true? I'm considering getting a UV filter to protect this investment. *please I do not wish this thread to become a UV vs hood deba...

filter with 35mm limited?
The only 49mm filter I have is a cheep +4 close-up filter which was an impulse buy that I hardly ever use as I have a decent macro lens. However the built-in hood on my 35mm limited clears the outer edge of this filter with a little to spare so it is not even fouling the flock on the inside of th...

I have Hoya 49mm LPL and UV (not at the same time :D) for mine - no problems.

filter with 35mm limited?
I've found that the old genuine Pentax filters definitely have a thinner ring than third party ones. I can refit the older lens caps over the 49mm yellow one I have, but not with any of the otherwise fine 3rd party filters I use. There isn't much in it at all - we're talking the proverbial cigar...

Change of plan, wise?
LBA! :lol: I just add the Tamron 70-300 to the list (just bought a decently cheap used one off ebay - I have been too slow several times with our Classified forum :oops:). This will be the de facto "Safari lens". And just like I do with every safari lens, I will put it through my unscientific moo...

Prime?
Pentax were rumored to have made 50mm's for other marques and the Ricoh 200mm f/4 is as being the same as the Pentax-M even though the filter sizes are different. Pentax urgently need an equivalent to the Canon 100-400mm lens :cry: Or Tokina release their latest 80-400mm. I've got the older on...

Who needs a big white one?
"modern sensors sure resolve the shortcomings of an optical system" do explain further. Ken Although film as you know is capable of the highest resolution the emulsion upon which it is based scatters light softening the potential highest resolution the film grain technology is capable of and can...

Lenses & TCs Test @ 300mm + x1.7 + x1.4 etc.
This lens surprises me John. I got it in a package I bought on EBay and although I've hardly used it I can't bring myself to sell it .. yet. Sharp, fast AF but ugly as sin and noisy. Still an excellent lens though. That sums it up very well, mine sometimes finds a place in my prime lens kit, replaci...

Autofocus with the FA 31mm and FA 43mm limiteds
I am now the proud owner of the FA 31mm and FA 43mm limiteds (the latter very recently). I have heard this mentioned before, but I have much more difficulty auto-focussing with these lenses than other lenses such as the DA 21mm and the DA 40mm. Does anyone have any tips or workarounds to impro...

Affordable lens set for best results: wide zoom and primes 30, 50 & 135
Unless you actually want to use the lens on film with a body which requires the aperture ring then go for the DA 35/2.4 instead of the FA 35/2. It's a lot cheaper and every bit as good. You can buy them new from SRS for £150, it will be under €200. If you want to try the Pentax-M 28mm then go fo...

tammy 17-50 vs sigma 17-70 OS HSM vs 18-135mm
Hello, I own a tammy 17-50mm f2.8 which I am very happy with in terms of quality. I however realised this wkd that 50mm is too short for me! Although I own a 18-250mm which I find really good when travelling, I dont think we can compare the quality of the two. Therefore it leaves me unsatisfied (...

18-135 has been slaughtered by Photozone
If you read the technical results in detail then it shows what might be expected ffrom thi, and any other, lens. That is, very high MTF20 results showing the scrisp contrast and "grittiness" and the lower but OK MTF50 results that show this is at the expense of fine, high resolution. This is actu...

18-135 has been slaughtered by Photozone
As for Monet, why not just use a properly-functioning lens and then apply a Lightroom softening filter? Because the Lightroom filter is one specific type of effect. On the other hand, we might find a cheap Domiplan lens in a car boot sale and find that it produces something quite different and usefu...

Help me with a weird problem
Hi all. I am going to describe to you a weird problem that I encountered today and wonder if you can give me an explanation. It goes like this: I have a Pentax A* 300mm which I was messing about with today. I decided to see what sort of results I'll get with a CPL filter, so I stick one on. Suddenl...

Thanks what camera are you using ? It happens only with the CPL filter or even without the filter the lens doesn't focus well ? It is the K5 that I use. Its only with the CPL, otherwise the focus is perfect. There are two types of polarizer: circular and linear. Linear polarizer are known to thro...
