Lenses & spectacle cleaning
These days, I try to avoid cleaning lenses unless absolutely necessary. When I have to, a product I have found to work well with filters and lenses is 'Calocoat' which can be used with 'Calocloth' or any other high quality microfibre cloth. I always spray a little onto the cloth and not directly ont...

Lenses & spectacle cleaning
The Pentax lens cloth is the best I've ever used to clean my spectacles. I went to get a couple every time I went to Britain. Now SpecSavers have opened shops in Norway, so maybe I can get the cloth locally hereafter.

J.Peg or Raw
The other one I've heard is "You're not getting the full 10mp unless you shoot RAW" Now I can sort of see where this idea comes from as the JPG images are smaller files than RAW, so the camera has obviously discarded some information it regarded as meaningless while processing the data. But it's ...

J.Peg or Raw
I have a K20D and I always shoot RAW. The camera had a vertical banding problem which has proved an unbelievable pita to get repaired but the sensor and PCB have now been replaced. When I first started using it I shot JPEG's and I must admit I was very unimpressed indeed, so I shot RAW and I have c...

John I'm going to try those settings in my KM post some and see how close my 10.2 sensor compares with a 14.5 sensor, I've got plenty chances of taking pictures Friday ,as I'm off to Norwich for a look around including the museum. Paul what settings do people use that get 'baked in' to the JPEG...

I looked this up for you i hope this helps! A Raw file is… • not an image file per se (it will require special software to view, though this software is easy to get). • typically a proprietary format (with the exception of Adobe’s DNG format that isn’t widely used yet). • at least 8 bits pe...

Pentax K7 lens profiles for LR3/ACR6
I believe if the sensor size is different (number of MPixels) there will be some dis-similarities in how well the profiles work. But I have heard, at least on the Canon and Nikon side, that profiles will work across models with similar sensor size/shape. Otherwise, I believe you will be allowed ...

Pentax K7 lens profiles for LR3/ACR6
I believe if the sensor size is different (number of MPixels) there will be some dis-similarities in how well the profiles work. The difference is not in the number of pixels but the physical size since the capture image from the lens is either larger or smaller so the distortion might be less or mo...

pentax ff camera?
I hope they don't go copying everybody else on the 4/3 system... I'd be happy to see a kx with fixed pelicile mirror and a leaf shutter lens.... but the idea of a big sensor, kmount hefty sized 4/3 styled camera would surely be unique and sellable would it not?

pentax ff camera?
that fits pentax full frame lenses.... This could only happen in dreams. The register distance (distance from lens to sensor) must be the same or else you lose some focus range. Since the register distance must be the same that means the image the lens make is too small to cover the whole sensor. :...

How much is enough (or too much?) (Digital Processing)
Hi all! I have no digital enhancement software outside iPhoto and after my experiences learning with film over the last few months I have found myself pretty happy with the results of my film shots without any digital processing. Now, I have generally avoided any post upload enhancement on my ...

Nikon is going EVIL
I like the patent for a cover over the sensor when you change lens. The more mysterious thing is - why has it taken 10 years of DSLR's for someone to come up with this?:?: It wasn't so much of an issue with 35mm SLR's because you moved-on to the next frame, and with Film you have a camera assista...

Nikon is going EVIL
Flossie, the shutter is actually closed when you've not pressed the release button with (D)SLR so no need for a cover over the sensor because only when you press the shutter dust can go onto the sensor. Sigma has solved this problem by placing a filter in the lens mount on the camera so no dust can...

Nikon is going EVIL
That's the lens mount not the sensor. The shutter is placed just before the sensor so you need to move the mirror up to see it properly. If you don't believe me about the shutter resting position do a 2 second delay with your lens off. With the two second delay the camera will flip the mirror up ...
