Old Lenses - Better Images?
I much prefer the output of my Vivitar S1 105mm f2,5 macro to the Pentax 100mm f2.8 WR. Only problem with the Vivitar is the weight and the massive focus throw.

Lens Shootout:: Pentax Prime Lenses 30-35mm
I am visiting the Americans more now and uploads are larger, so I'm getting used to them. I find a 1280 px width much more pleasurable to view than 800. It's a bit like going back to 28" tv's which used to be plenty. I'll include some 100% crops, but I think these photos still give a good impre...

Lens Shootout:: Pentax Prime Lenses 30-35mm
They all look so good I suppose it will be all down to budget :) Choose the FA31 if you have the money and don't mind the bulk. (I do.) Along with the K35 it is best for manual focus. Choose the FA35 if you don't mind the build and absolutely need f/2. Choose the DA35 to save money. Choose ...

I have a penchant for the Pentax colours ;) I've got the DA16-45 (my son now uses it on his K10D) and it is an excellent lens. Colours, sharpness and contrast are excellent. The range is slightly narrow, but not generally a problem, and the bokeh is, IMHO, ok but not brilliant. I've had the DA...

To be honest, I don't think you can go far wrong with any of those four, so it all kinda comes down to what you want. The Pentax 16-45 is probably cheapest, but doesn't have a particularly big zoom range. It does have the Pentax colour reproduction in it's favor. The Pentax 17-70 I owned brief...

I don't have any experience of the Sigma or Tamron, but have the Pentax DA17-70 and FA24-90, and used to have the DA16-45. The 17-70 is the 'default' lens on my K20D (in the process of upgrading to K5) and is generally excellent - sharp, rich colours, and smooth bokeh - but it is the only lens that...

Just a layman's question - how much better results will I get with any / all of the above mentioned 4 lenses? That depends. Generally speaking, these lenses should give you better results (sharper picture, better colours, nicer bokeh), however, if you mainly shoot F8 or smaller aperture landscape...

Lens Shootout: Pentax Prime Lenses 50-55mm
Interesting, keep 'em up, the more the merrier. I think the K55 is sharp, just takes a lot of getting used to the focus and pinpointing where used at wide apertures. More from the Tak, which I believe is optically the same as the K, probably taken at f2, certainly no less than 2.8: SMC Taku...

Prime Killer ;-) Pentax-F SMC 28-80mm f3.5-4.5
You could have posted them here Andrew.... no problem :wink: I still like the 'A' Series version of the 35-70mm f/4 and the infinity focus is spot on, so ate 35mm you can set it to f8 and infinity and not have to bother re-focussing. It's also slightly sharper, but not as good as the F 28-80...

Prime Killer ;-) Pentax-F SMC 28-80mm f3.5-4.5
You could have posted them here Andrew.... no problem :wink: I am happy to do so ........ Not exactly "in the wild", but I did hurriedly blag off a few shots with the SMC F 35-70mm in the garden late this afternoon to check whether the AF micro-adjustment had been a success. Most of them are s...

Prime Killer ;-) Pentax-F SMC 28-80mm f3.5-4.5
I dont understand this thread at all. Any lens will work fine at f/8 its the middle of the aperture Range which is unchallenging fir most glass. If youare going to take images at f/8 what's the point of getting a DSLR? Usng f/8 might as well do away with auto focus and use zonal methods too you mig...

Quick-Shift hardware?
has anyone been inside a DA and a DA-L of the same length and compared the focus gubbins? Specifically wondering if the little clutch pack from a DA is a drop-in replacement for the gear in the DA-L... signed, an inquisitive 55-300DA-L owner.

SDM failure? help.
Hi folks, Have been rested up for a while, but now back on the mend and the camera is out again. :) Anyway, went out on Saturday with my K5 and a few lenses. I then decided to pop on the 50-135mm and take some shots. Compose scene and focus... nothing... try again... nothing... Switch...

SDM failure? help.
Incidentally my 60-250 was the one of the first failures on that particular lens, fixed under warranty but the lens packed up after being laid up for a few months...the jeweller's screwdriver in the screw drive worked a treat. This happened to me this weekend, 60-250mm wouldn't focus, it seemed to b...

Thanks for the replies... DO NOT get Craig Whyte involved in it!! :D:D:D (Wee Scottish football joke, folks!!) Steven, I've got bigger problems 'said the Aberdeen supporter' :oops: I've read that sometimes you can 'bump start' the SDM after a lay-off by manually operating the screw drive wit...

SDM failure? help.
I occasionally find that my 50-135 has a bit of difficulty focussing if i haven't used it for a while - it sounds as if the SDM motor is trying to do something, but the focus movement is negligible if anything. I normally (a) clean all the contacts and (b) grab the focus ring and (not too madly, i.e...

Every time I think my SDM is broken I faff around for a while, eventually flick the switch on the lens back to AF and it works again.
