Boot sale bargain
Good find, I have that lens and it is a cracker. I picked mine up second hand for £35 from Camera world but it is a very rough copy, loose focus ring and the PKA adapter was faulty but I was still happy.

Updated Roadmap
One strange thing though. DA14mm still on the list? According to the Pentax rep I spoke to a few months ago, this lens had been dropped. Have they brought it back?

da16-45 autofocus focus issues
I've had my da16-45 for a while now and for the last 2 years I've had some issues where you half press the shutter button and nothing happens apart from a strange noise for a fraction of a second. Sometimes if you point the lens at an object further away the lens will autofocus. I thought this wa...

da16-45 autofocus focus issues
Not sure what the problem is, if there is a problem? I have exactly the same issues with my 16-45. I find, on occasion, I have to focus on an area with more contrast then it locks on focus. BTW, mine is the Samsung branded 16-45. I'm in love with the results this lense gives and so forget the occa...

Where Do We Draw The Line?
I think I'd distinguish between manual and auto focus. So the line gets drawn after SMCA? Jon

Where Do We Draw The Line?
I use lenses with the Pentax K mount on my DSLRs. So I draw the line between M42 and K mount. I especially enjoy using SMC-K lenses, and do not regard lack of "A" setting or manual focus as any problem at all. The SMC-K lenses (especially) have an impressive build quality, and they perform marvelous...

Where Do We Draw The Line?
I think I'd distinguish between manual and auto focus. So the line gets drawn after SMCA? Jon I'd agree with Jon. The AF lenses are much more suitable on DSLRs, not just the AF but better integration with focal length reporting and lens corrections. But I'd hesitate to use vintage/collectable for ...

Where Do We Draw The Line?
A*'s + A50 f/1.2 upwards and onwards. Anything beneath them or older vintage are basically lacking in optical ability. I would also argue that the F series should be discounted as they are just too lacking in tactility due to their build but that is me being a lens snob :D The simple solution to ...

Where Do We Draw The Line?
As much as we look back to the good old days or lens series in this instance with rose tinted glasses, progress and technology rarely stop. The , lenses are best left to old farts stuck in the past who still like to use the focus ring on and don't see the need for dozens of aspherical computer de...

Where Do We Draw The Line?
why not just describe the older stuff as BOTH collectible and usable? The answer to that is quite simple - two categories means two listing fees. It was an interesting point that I was mulling over when posting stuff on eBay. The "lenses" section does actually include some catalogues entries fo...

Help - lens question for stereo print experiment.
You can also take stereo shots of static subjects by using a focus rack turned through 90deg and moving the camera by the distance between the lenses between shots. --

FA50 F1.4 vs. M50 F1.4
Hi everyone, just looking for some advice on the FA50 1.4 lens. I have a selection of 50mm (ish) lenses, all of them manual focus: M50 F1.4 A50 F1.7 K55 F1.8 Chinon F1.9 I like all of the above, but my particular favourite is the M50 F1.4 which works like a dream with the K-01. A friend...

FA50 F1.4 vs. M50 F1.4
I think the focus on the k-01 is slow anyhow due to the war it works, its has to focus from close to far to make a calculation and like you have found manual focus with the focus peaking more satisfying and quicker. I don't have the FA I do have the older F version and find it works brilliantly o...

FA50 F1.4 vs. M50 F1.4
David, if it helps. I have both a M50 and FA50, used a lot. The M50 is a F1.7 and the FA50 is a 1.4. I have found the following:- The M is better wide open. It has CA but it is small and "hard" so easy to remove. The FA50 is more dreamy and more difficult to get rid of. The M has a lot more c...

FA50 F1.4 vs. M50 F1.4
I have just acquired an FA50/1.4, hopefully* to replace several of these: M50/1.4, M50/1.7, A50/1.7 and F50/1.7. The FA has a much smoother focusing ring than the F and this might allow me to sell some of the manual focus lenses - which I currently use on manual film cameras. I haven't been able ...

FA50 F1.4 vs. M50 F1.4
The lenses are the same optical formula throughout, but there may well be development in the coatings and there's always sample deviation as well. The FA lens we have works fine on the K-5, just as snappy focusing as anything else. However, I'm thinking if you really like the M series lens you...

The 50mm 1.7 - Discuss
Great lens - the 'A' variant is probably the most easy to use if you're going for a manual focus one, but build quality is better on the 'M' variant. I would highly recommend the following: M50 F1.7 M50 F1.4 K55 F1.8 For a really cheap option that is rather good, the Chinon F1.9 can be ha...

Is this fungus?
Yes, I'll try cleaning it again. Now that I'm satisfied it's not fungus, I've finally mounted it on my K5 and taken a few test shots and so far I'm pleased with the results. Although I'm still a little worried about the long-term significance of the spot, I'm also quite reluctant to return the len...
