Which wide angle zoom would you go for?
The 10-20 is a great lens but with a wide angle the F3.5 isn't important. most things are in focus anyway and it is normally used with a smaller aperture anyway so the original 4-5.6 is cheaper and does the job. I know nothing of the 8-16 so can't comment. CHEERS Vic.

DA 17-70 - fixed!
A few weeks before Christmas, my DA 17-70 stopped reporting focal length correctly to the camera. Ie no matter what focal length the lens was set to, it reported back a constant mid-range value of 43mm. This meant that SR wouldn't function correctly, so I sent it off to Asahi photo to have a look (t...

DA 17-70 - fixed!
Johnson's charged me £120 inc VAT for this repair in July 2012. Then it had to go straight back as it did not report back correctly at the extreme wide angle. This happened again in May 2013 and they repaired it again for free (goodwill repair as now out of repair warranty).

the holy grail..
Does it weigh more than a Tonne? :shock: (Well every other daft question has been asked :lol: ) I was hoping that they'd bring out a 1.5x Back to Front Converter that left the lens as it was, but magnified the sensor so that it was FF :shock: :wink:

The gasket is on the back of the lens jules, so it would be on the back of the converter.

the holy grail..
I know people have been clamouring for this for ages now, I wonder what makes it the holy grail? The f1.7 converter seems to do a very good job with the right lenses. Will this be a significant improvement on that? WR is obviously welcome. The 1.7 AF Adapter dates back to the late 80's and was of...

The gasket is on the back of the lens jules, so it would be on the back of the converter. Doh! Of course it will be using the gasket on the lens side for the other seal! Was hoping for some rubber on rubber action.:twisted: I agree with the others here however, it seems difficult to imagine what...

Pentax HD Pentax 1.4x Teleconverter
Must be better than the third party one that I bought which is pretty rubbishy. Most of the functions don't work!!! Would make my 60-250 f4 a 84-400 f5.6. If the auto focus works it would be great

Pentax HD Pentax 1.4x Teleconverter
Interesting post on DPR from someone who seems to know a bit about Pentax. Be sure,all the electronic stuff is inside the converter. Every ID is transmitted between camera and lens. And the nice point should be,the release date means new firmware. The current Pentax bodys are without any...

Pentax HD Pentax 1.4x Teleconverter
Indeed we do John and I think people often forget this. A small bird is constantly moving its head even if it appears still. Another reason why we tend to use burst mode. Back to the notion of a heavy f2,8 300mm - provided the f4 focuses well with a TC isn't F4 the new F2.8 with the current improve...

Pentax HD Pentax 1.4x Teleconverter
What is the longest lens you can use with a TC and SR (i.e. not on a tripod)? I've used a 300 with a TC handheld and got some reasonable results (I would normally use a tripod with this combination), but I would have thought it gets less and less good the longer you go:?: Frequently use 300mm with a...

Oh great! thanks a bunch for flagging this up! I was going to buy one of these 30 quid cheaper and now it's just gone up. Brilliant. Way to go people, moan about something being too cheap... Er I didnt put the price back up - If you wanted one at £349 why didnt you order one when I posted the link ?...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
Hi, New here and I've got a question for a Pentaxian. I had a bad experience with a Sony A580/SAL 18-250 zoom lens. Problem with such a zoom is that it's a hoover, sucks every last bit of dust into the workings; onto the sensor and all over the inside of the lens. Nice camera good photos but h...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
Thanks, All that makes me think that Sony don't quite have it all right! (Or perhaps Pentaxians are just a bit on the loyal side...err joke, no offence meant). Good video, I managed to hoover up a bucket of dust with my Sony and that was being ever so careful...not even taking it out of its ba...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
I'd go for the K-5ii if dust is an important consideration. And for ultimate IQ suggest the iiS if you can find one at a price you're happy with. I found the DRii removal system is more effective than the sensor shaking earlier DR system in the K-30/50 bodies. Also generally tank like build and v...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
This post takes me back a little. I spent a couple of years flat sharing with my brother who had a couple of Sony A series cameras. He used to spend a couple of nights a month cleaning his mirror and sensor! Not something I've had to do with either my K-r or K-5. Odd that it never entered my mind...
