New Walkabout lens recommendation
all things being said... I'd love to buy the 16-50....and nearly did, but a sale price on the 16-45 clinched it for me. I'll just work around the one stop diference. I have plenty of lenses and back-ups. If I was in this fellas shoes... I'd opt for the second body, and give the fast primes some ...

New Walkabout lens recommendation
The "internet effect" has put me off the 16-50 completley. I have the 16-45 so I'm not too worried. I don't let nitwits on DPReview make decisions for me. G So I'll just ignore what you've just said then George ? :D Seriously however there do seem to have been more than the usual n...

Pentax F 70-210
Well mine went for 110£ a few months back - sold to someone from south korea. That seems to be the price for it. I did track a few of these lately. All around 90-120£

New DA* 300mm F4 + test shot
I got my new DA* 300mm F4 from SRS today. I've only had chance to test for 30mins, I'm going to Muncaster Castle tomorrow so hopefully I'll have a few Heron and Owl shots to show you. My first impression of the lens is there could be a 100-300mm F4 EX Sigma for sale soon. The autofocus is so quiet...

New DA* 300mm F4 + test shot
It couldn't allow regular lenses to become SDM, as its a technology built in to each lens. It could be done to the extent they achieved auto-focus for manual lenses with the AF 1.7x converter. That is, you rough focus your lens manually and the converter fine focuses using an SDM motor moving an el...

Pentax SMCP-FA 80-320mm f/4.5-5.6 Lens
Cheers for the advice, allowed me to nab it quickly before someone else jumped in. Not sure if I would have been so quick if it had been silver although I have since done some research on the lens and seen some excellent photos done with it. The general opinion certainly seems to be that it goes so...

My DA* 50-135 is a 'Write Off' according to Pentax
I keep a filter on the majority of my lenses and I started to think it might not be such a good idea... When I was at Arnhem zoo a few weeks ago I noticed my K10D was struggling to focus with my Sigma EX 70-200 (I had no issues previously)...also found it was difficult to remove the lens cap Whil...

My DA* 50-135 is a 'Write Off' according to Pentax
I don't know about Pentax but I saw a video a while back of Canon's lens assembly line and they were done by hand. http://www.youtube.com/watch?v=KpkAWZTwqI4&feature=related You can start the series here if interested: http://www.youtube.com/watch?v=OkWsk9rXpcU&feature=related ...

Sigma vs Tamron 70-300 - First impression
I've had chance to try out the Sigma a little more over the weekend, taking a variety of shots. I've decided not to post any more images as it's not really my intention to produce a "scientific" comparison - I'll just comment on my own user impressions... -- Sharpness, inline with r...

Canon lens on Pentax
A friend of mine has some very expensive Canon telephoto lenses which I can borrow. Is there an easy way to mount these on my K10D? I assume not, as there would be less moaning about sports lenses for Pentax if it was possible. I am not expecting anything but manual focus and stop down metering, ...

Canon lens on Pentax
ah well, worth asking, he has said I can borrow the 1D also, but he is 100 miles away so I would be in for a lot of driving if I had to keep giving the body back every day. whereas the lens is just a door stop most of the time. Hows the Bigma Clarky? I don't think I've heard anything bad about th...

50-135 2.8 SDM
The 300mm DA* certainly feels faster and more accurate to me than other lenses I have at a similar length. I'm not 100% sure that it definitely is, or whether the fact that the focus is nearly silent makes it seem so, though. As George says, tracking moving objects really is an art in itself. If ...

50-135 2.8 SDM
I was using my 50-135 to photograph my son throwing snowballs yesterday evening and it performed very well on continious focus and multi shot drive mode. I have been looking at the continious focusing and it seems very quick, however, I have not tested it against any of my other lenses. The brig...
