DA 18-135 WR. Weatherproof, but will it keep dust out as well?
Hi, Thanks for all of your advice; much appreciated. Since during any zooming of the lens air has to be sucked in and out of the camera, are the weatherseals on the lens/camera good enough to stop all dust being drawn into the camera body (particularly that very sticky pollen which finds its ...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
Have a look at this: http://www.youtube.com/watch?v=Eo61t5fH6Qw&feature=youtube_gdata_player Truly, the problem you describe is not a problem. I have had my K5 for several years, frequently using zooms (including those not weather-sealed), and have not yet had to clean the sensor.

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...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
Hi, Well, this all sounds very promising and the thought that I could sit down with a beer in the evening without spiralling into paranoia about how much dust has accumulated on the sensor after taking only a few photos fills me with great cheer Are Pentax cameras that good or is that Sony con...

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
I have been using Pentax DSLRs for a long time now, since about 2006, and I have never needed to use any sensor cleaning that meant touching the sensor. The inbuilt dust removal usually is enough, but from time to time a rocket blower may be needed to remove a stubborn speck.

DA 18-135 WR. Weatherproof, but will it keep dust out as well?
Hi, Been looking into either the K-5ii or the K-50. Both look like good enough cameras (and I think I read that the sensors are of Sony origin! Can't be bad then!!) and are going to take fine photos. Which one though? There's a bit of a price difference but seeing as dust is my anxiety it...

Scary D.I.Y. Project for Smeggy!
I'm sorry but I wasn't impressed. Have I missed something ? You're probably too busy pixel peeping :) Only kidding, but although it's late for me and I'm tired so haven't read all the text ( and it seems a google translation at any rate ) , the pictures themselves certainly have some personality,...

Two more front ends
so here's a thought: what will y'all say if the rumored DA* 135-380mm is for crop-sensor only? Would that finally squash any feelings that a full-frame Pentax were on the way? Personally, I'm betting it is for crop sensor as Pentax's trend wrt lenses has been to offer lenses that are smaller/lig...

Sharp Long lenses for my K-30
Why the seemingly obsessive priority on sharpness? While I appreciate a crisp image, IMO the emotional content of the image is far more important than pure sharpness. And don't forget you can increase sharpness in post processing anyway. The IQ Quality of a lens is far more than just sharpn...

Tamron 17-50 non-vc
Have a look on photozone.de the Tamron from the nikon dx section. The DA35 is 2478 wide open and 2723 at f4 compared with Tamron at about 2150, You're spoilt.! Or is that sensor resolution?

Sigma 70-200 F2.8
Hey Mike, thanks for that snippet, I didn't know that, I have noticed that the lens reports its "full frame" focal length, even though on the Pentax body it is X1.5 times that, it would have been nice of them to correct the reporting so it is recorded correctly by the camera. Nope. A 200mm lens is ...

HD PENTAX DA AF 1.4X AW Rear Converter
Unfortunately the birds weren't playing today. The camera stood for 4 hours pointing at the feeder but nothing came :( Expanding on MIke's point, I'm actually wondering if the 0.4 factor is worth it. With the sharpness of the DA* lenses combined with the K5 sensor I'm fairly certain that an eq...

HD PENTAX DA AF 1.4X AW Rear Converter
Even 1.4 could enable you to get a more accurate focus on the intended subject - which cropping would not do. and so long as there was no IQ degradation it would be worth it. However I'm not certain yet Well there will be IQ degradation, with any teleconverter. But if you are using a good lens,...

HD PENTAX DA AF 1.4X AW Rear Converter
I suspect the benefit will come to wildlife photographers who need to heavily crop, at the point where the image without the TC would be close to getting pixellated, the TC image giving that bit more latitude. Yes, arguably doubling the effective pixel count of their sensor (32 MP for a K-5! There w...
