what is the difference between a F and a FA 50mm 1.4Lens?
How much did you pay? A Pentax 50mm f1.4 auto focus lens is worth quite a bit. The A series manual focus will fetch upwards of £100!

what is the difference between a F and a FA 50mm 1.4Lens?
How much did you pay? A Pentax 50mm f1.4 auto focus lens is worth quite a bit. The A series manual focus will fetch upwards of £100! No, this didn't help very much. However the SFX camera came with the 50mm lens and also with a F 35-70mm lens. I paid about $ 60.- for the lot. Regards, Horst

what is the difference between a F and a FA 50mm 1.4Lens?
Does anyone know what the difference between the F and FA lens is? The F series of lenses were Pentax's first auto focus range. I believe that many of the FA versions are optically identical to their equivalent F series lenses and that only the body styling was changed. So I believe that your S...

18-55 kit vs 18-250 mm
According to photozone, as far as sharpness goes they're similar at the centre but the 18-250 is a little better at the edges. See the MTF resolution figures: AF speed of the 18-250 will be slower if it is a long way out of focus, however. Manually approximating focus first (to just bey...

What's your 'Best Buy' Lens?
Probably my DA*50-135mm. Hardly off the camera, and used for events, portraits, outdoor, monsoons etc etc. Bargain lens - my K-55mm F1.8 £20 on e-bay a few years back.......:D

What's your 'Best Buy' Lens?
I bought a K55mm f1.8 with a dented filter ring for £2 several years ago - It was every bit as good as the other manaul focus 50mm's that followed it - but I have absolutely no recollection of what happened to it :lol:

What's your 'Best Buy' Lens?
pre-price rise and post-repair DA*60-250, I had bought the 55-300 as a back-up but that has since been sold as the DA* is just a joy to use....the photos I took in Venice were just so satisfying.

What's your 'Best Buy' Lens?
I forgot to mention my 300mm Tamron Adapt-a-matic in mint condition for £20. It doesn't get much use as I have a 55-300 and a Siggy 50-500 too, but when I do use it I get a lot of pleasure from it. I've had it up for sale on here recently with no offers:shock: but I won't be letting it go for a so...

Which one to keep?? Tammy 17-50 or Pentax 16-45
I just acquired a K-5 which came with a 16-45 f4. Now I will sell my old K20d and one of the above. Question is which? I have taken a few comparison shots with each lens and colour wise and sharpness I cant see too much difference...maybe thats down to my lack of skill!, but in any case I thoug...

Which one to keep?? Tammy 17-50 or Pentax 16-45
Thanks Guys, Im going to take some more shots with both this week, just to confirm, but I am leaning towards the Tamron cos its faster and I have two young girls who dont sit still for more than 0.5sec! I think it will be a better option for the long winter months, taking indoor shots. The sa...

Faulty DA*300?
Been trying my new DA*300 today for the first time. This is my second one, owned one until last year when I sold it as I was not using it. But missed it so much, got another one. Now this one seems a bit noisy during focussing, and fails to focus reliably (where my DA 18-135 WR just nails the...

Faulty DA*300?
It's certainly possible, I bought mine earlier in the year and was not in the least impressed :shock: It was back focussing too far for the in-camera correction to have any effect and, like yours, the focussing was unreliable. It went back and the (focussing?) drive motor was replaced under guar...

Faulty DA*300?
Can anyone else confrm what the manual focus feels like?

Faulty DA*300?
I have just compared the two and the manual focus ring on my 18-135 is noticeably 'stiffer' than that on the 300. The 300 ring is much smoother in operation but in no sense loose. Auto-focus is also completely silent.... Roger.

Faulty DA*300?
Thanks Just received a replacement and the new one definitely better at focussing and manual focus slightly more damped.

The ultra wides are certainly tempting, and I'm delighted with my new Samyang 14mm (a full frame model, gives about 22mm in old film terms on the K7). But it takes getting used to composition wise. Its easy to stand back and shoot the big view, but you risk ending up with vast spaces of dull fore...

Vivitar Series 1 28-90mm F2.8-F3.5
One of the first lenses I bought back in 1986. Took thousands of pics on it back then. Still got it. :) Got yourself a bargain there. :)
