I also use lens wipes, the ones I currently have came from a discount shop and IIRC cost me £1.99 for 100. The brand name was Zeiss although I doubt they are from the camera manufacturer of the same name:D Not had any problems with them whatsoever and they're also invaluable if you wear glasses t...

Help with a Cloudy Viewfinder
No Drew, I haven't tried that one, but I have tried something that I thought would have been even more effective. I left the K-x in the Rayburn's warming oven overnight (don't worry, it's not much hotter than a hot airing cupboard). The lens was off, wrapped it up to prevent dust ingress and raise...

aperture/depth of field on pentax x5
I dont have an X5 but from Optios and my Q I have discovered that you are correct in thinking that the landscape mode increases the greens and portrait mode warms skin tones. The problem is that the sensor is so small and requires very short focal length lenses which inherently give a great dept...

aperture/depth of field on pentax x5
I dont have the X-5 but used to have a similar panasonic camera. As ken said, It is hard to achieve shallow depth of field due to sensor size. The best way is to zoom out as far as practical (with a 26x zoom full will pit your to far away) and set the apeture to widest setting possible in manual mo...

Adaptall KA mount won't lock on lens
That is a picture of a 17mm. looking at a 28mm the claw does not protrude at all, so it may vary from lens to lens. Both those lenses only have three screws holding down the rear plate and the release lever pivot. I'd be tempted to have a look and see what is happening, it may only need cleaning...

F lens and FAJ lens not recognised by MZ-7 - Help!
Just a thought, have you tried cleaning the contacts on the lens as well? A slight film of grime can stop them 'talking' but may not effect the lens on a DSLR.

am I doing something wrong? .
Thanks jeallen01. Sorry about the Sigma 10-22 reference it should have been 10-20. It was slip of the keyboard but I think some other makers have a 10-22. your comments about the old film era lenses being not so great are interesting in that many talk about how great the old prime lenses are. perhap...

K-5 Focus Questions
I would welcome some advice from the knowledgeable members regarding some AF questions on the K-5. Today, I've done a Wedding Shoot with Shaun Wilson and to ensure everything was ship-shape prior to this, I systematically calibrated the AF on all my lenses yesterday, both on the K-5 and the K-5II...

K-5 Focus Questions
When we discussed AF adjustment before, someone agreed with my supposition that the adjustment was like adding a shim (or even an imaginary negative shim) between the lens and body to adjust the focus (lens focal point) to sensor distance. If there is the possibility of something working loose ar...

K-5 Focus Questions
What I've never quite been able to wrap my head around is WHY adjustment is needed per lens. Consider: AF fine adjustment puts in an electronic offset to compensate for a difference between sensor and AF device path lengths. Sensor is "fixed", but both AF sensor and matte screen are at an adjusta...

K-5 Focus Questions
I've been trying to get to grips with calibrating the focus on a DA*50-135mm I picked up off eBay a couple of weeks ago. I've since tried to calibrate all my lenses. What a can of worms it's turned out to be. I think the problems described in this post are the reasons I haven't tried to calibrate ...

ND Filter Help
Even though it was overcast it was probably quite bright. 10 stops will extend exposure by a factor of 1024. The equivalent exposure time without the filters would have been about 1/640s, which may be about right, although it does seem a bit on the short side. Bear in mind filters do vary and the...

Thanks so much guys for the advice. I will look into the heliopan. My Kx is very dirty but cleaning the sensor doesn't seem to help. is there anyone i could send it too?

Depends where you live. I've heard Advanced Camera Services in Norfolk recommended. However, if you only paid £4 for your filters you might baulk at what it costs to get a sensor professionally cleaned!

my local dealer ,Clifton Cameras, charge £45 for a wet and dry sensor clean, when i last asked how much. the blue cast of hitech is a lot easier to remove than the magenta of cokin i have found.

is there nobody else, not sure i would trust them with a response like that. I definitely wouldn't trust them, sounds like jessops. Get some proper sensor cleaning swabs and do it yourself, it's not difficult, just follow the instructions to the letter. I did my Kx without any problem:)
