Tamron Adapt-a-Matic Lenses
Hi Paul, I definitely have an Adapt-a-matic and it's a 300mm F5.6 in beautiful original condition. Made in 1972 and hardly a mark on it, it has an M42 Adapt-a-matic mount, and also has a Minolta SRT adptor. I use it on the K-5 and K-x, with a flush-fitting K-mount adaptor permanently fitted. I ...

'SMC' to 'HD' potential marketing disaster?
Super Multi Coating made sense back in the day. High Definition abbreviated to HD mostly means current TV resolution (much lower than our cameras can achieve for stills) so not sure what the idea is here. Personally if it works better than before I'm not too bothered.

New tamrons, but not for Pentax
Back on topic please. And again, attack an argument by all means, but not individuals.

New tamrons, but not for Pentax
Going back to the original subject...this is personally what I find frustrating as a Pentax user. We could potentially be missing out on these lenses along with the new 70-300mm if there are no plans to release them in Pentax fit. It's all very well releasing great DSLRs such as the K-5 but not ev...

"It's all about the glass". Show me examples please
One of my my photographic aims has always been to get to know my lenses intimately (no comments please) to the extent that I know instantly which lens to use for which shots. For example, I have 3 lenses that cover the 300mm focal length and will usually opt for either the Pentax 55-300 or the Sigm...

"It's all about the glass". Show me examples please
I have too admit to not knowing the exact age of my Tokina 300mm f5.5 m42 lens but I love it - apart from the minimum focus distance of around 5 metres it's cracking - check out my flickr set for it - I probably don't do it justice but at a cost of £16 plus postage I will take the risk :D

"It's all about the glass". Show me examples please
I agree with the general idea that spending money on lenses can give 'more bang per buck'. In the case of upgrading from a K7 to a K5 or buying lenses, then personally I'd opt for new lenses..... What's the point of buying new lenses if you can't use them :shock: The K7 or K20D is pretty useless at...

"It's all about the glass". Show me examples please
To get back to the OP's question...:) The Pentax lens review forum on the is a good place to find out what people think of different lenses. I've bought about half of my lenses after having a look there and on other forums, and ended up with some great reasonably cheap lenses. I've probably sav...

"It's all about the glass". Show me examples please
In defence of the lowly K7's capabilities, here are a couple of shots I took recently - iso 1600, no flash, lens was an 'A' 28mm f2.8. I did remove some shadow noise, but the edge detail was easily bought back. I was getting workable shutter speeds in the region of 60th-90th sec, and I feel the ...

"It's all about the glass". Show me examples please
All of my lenses I'd consider fast (tamron 17-50 f2.8, Sigma70-200 f2.8, Pentax 100mm macro 2.8 and Sigma 30mm f2.8) I do not consider those first lenses particularly fast. A lens f/2 or greater will allow you greater control over depth of field, but of course it depends on focal length and distance...

I was just wondering....
The strength of Pentax's position is their huge back catalogue of great full frame lens designs, all fully patented. In fact the last few DA primes were actually tweaked and repackaged lenses from the film era. They work just great on digital.

SDM Motors in the 16-50 and 50-135
Hi! I need a help. I have a little problem. I bought a 50-135mm lens but not good the focus and somebody told me i must try the lens another camera. I live in Newport. Somebody live in Newport or Cardiff?

SDM Motors in the 16-50 and 50-135
Hmmm - I had a failed motor replaced in my 50-135 last year. Do I send the receipt to Pentax for reimbursement, I wonder? Well, I do not know if that would work, but I would try. As far as I understand, each country in Europe implements customer protection regulations differently and in the UK ...

Pentax 10-17mm Vs Sigma 8-16mm
I had both - first the 10-17 and I gave it back and got the Sigma 8-16. The Pentax Lense was not OK - the components were losely mounted and I was afraid that in the near future, the whole thing would fall in pieces. However - I don't think at all, that this is typical Pentax building quality - al...

Pentax 10-17mm Vs Sigma 8-16mm
I would be more then happy if they brought out a metal mount,well built 35mm f1.8 like Nikon has done for less then £200 which currently their best selling lens, I bet Nikon has sold more of that one lens then Pentax has sold in its entire current range, and I know there are a lot more Nikon users ...

Which old Pentax lenses to look out for?
Having just bought the Tamron 17-50 f2.8 off this very forum I've been looking around at other fast lenses such as the tamron/sigma 70-200. Unfortunately these are a little bit pricey, even second hand, for someone with a house move on the cards in the coming month. So I've been looking at some ...
