Sigma 18-125 or Tamron 18-200
There is a motor in Pentax bodies that drives a screw drive to focus most lenses. Some lenses have a motor in the lens, and the camera knows this and uses that option instead. This should be both quicker and quieter.

Tamron AF 70-300mm LD Di A17 Lens Info Required
I bought this lens recently as a local purchase off Gumtree. It came with no box, instructions or lens hood. It came with a Jessops UV filter. All for £45. I've checked the Tamron website and the images of the Pentax fit A17 doesn't match this one. The one on their website shows an AF/MF switch whe...

Tamron AF 70-300mm LD Di A17 Lens Info Required
I have one of these and find it a super lens. Although I now tend to use my Tamron 18-250 as a go anywhere lens, this one still comes out when the birds are playing in the back garden.

My first Prime for DSLR - DA 50mm, 35mm or ?
Tests? Why not look at pictures taken with them. Yes, that is what I meant - comparisons of photos taken with the two lenses. If you have samples of the same photo taken with the 16-45mm and one of the primes (sharp, in focus, same settings) that clearly shows the difference, please post them. ...

DA 18-135mm WR no lens hood?
Last week I ordered a blue K30 & DA 18-135mm WR as part of a kit from a Pro Centre (not SRS). It arrived this afternoon and the lens had been split from a kit but was missing a lens hood. When I rang the retailer they informed me that the K30 & 18-135mm combo did not include a lens hood but they w...

Does anyone have an smc Pentax-M 50mm F1.7 and an opinion :)
I have M, A and F flavours of the 50mm f1.7. All are wonderfully sharp. The M version is without doubt the biggest bargain amongst Pentax lenses. It's ridiculously cheap relative to its quality, purely because so many were sold in the 70s. Yes, the A is a little simpler in use since you have...

....For £30-odd, the M50/1.7 is a steal. *whispers* £12.50 :mrgreen: You did very well there! :D Some people ask almost that just for a pair of spare lens caps! If you're anything like me, you may find manual focus tough with moving subjects like pets (and children), and that static objects ar...

Does anyone have an smc Pentax-M 50mm F1.7 and an opinion :)
I used to have the M/1.7, in fact it was bought new on a MX with my first ever pay check :) I was quite happy with it until I got a secondhand Pentax M200/4 as my second lens and found results from that were far sharper and more contrasty. That sort of doesn't make sense as the 200/4 doesn't have...

Does anyone have an smc Pentax-M 50mm F1.7 and an opinion :)
I have the 'A' 1.7 version. What's are the differences between the A, M and F? I know the A becomes automatic when you set the aperture ring to the 'A' setting. Of course it's not auto focus. David PPG: http://www.pentaxphotogallery.com/artists/davidtrout

With the 'A' version you can use the camera to set the aperture and the metering will operate via the shutter release. When using an 'M' version aperture is set via it's ring and you have to use the green button to preset the exposure. 'FA' 'DA' etc are modern auto focus versions.

Does anyone have an smc Pentax-M 50mm F1.7 and an opinion :)
Interestingly I was piped on ebay today when bidding for a 55mm 1.8. Some day perhaps... Just do it! The 55 1.8 is magical! You will kick yourself if you don't buy one. :D:D:D Chris (Milamber) spotted this and saw an easy target, so I'm in the 55 club with my first 'K' lens. It's a peach, but did ...

Chris (Milamber) spotted this and saw an easy target, so I'm in the 55 club with my first 'K' lens. It's a peach, but did I really need yet another manual focus standard prime, me with my 50mm's M-1.4, M-1.7, M-2.0, M-4.0, A-1.7, A-2.0, & A-2.8? Well yes, of course, it's 5mm longer! This is get...

Why use 'old' glass?
It's a bit of everything really - many are real bargains, quality is superb, anything can be used fully if it has an A on the aperture ring (otherwise still can be used with some limitations), it's fun to experiment, it's fun to collect....it depends on your interests. In a practical sense, maybe...

Why use 'old' glass?
Some focal lengths just aren't available new anymore, I recently bought a manual focus 400mm f4 very cheaply the modern equivalent in canon runs around £4000ish... I think that's a good enough reason 8)

Why use 'old' glass?
Yeah, I think my answer would be somewhat along the same lines. The feel of a manual focus lens is part of what makes it worthwhile. The fact that you're having to focus the shot yourself makes you pay that much more attention, and perhaps makes you spot something else that you want to highlight ...

Why use 'old' glass?
Because they're RIDICULOUSLY cheap. You can walk into a charity shop, ask them if they've got any cameras/lenses, and they'll come out with a crateful from the back. They're usually M42 or K-mount, which is the reason why I chose Pentax as my digital system of choice. It's ALSO the reason why we ...
