10 stop ND filters and infrared
Well, as far as I understand the ccd powered gx10 could do alright for long exposures. But if Stefan is are right about the K5 then the problem should be pictures with a heavy colour cast because too much infrared light hits the sensor. On the other hand, the gx10 in my experience is no good for...

Macro photography question
Algi's and Glyns comments cover the main points but it is important to remember the raw visual data from the eye is subject to a massive amount of processing in the visual cortex before being routed to the part of the brain that then makes sense of what we are looking at in the viewfinder and define...

Macro photography question
IMO there is no such thing as a bad macro lens. You've not met 'macro' zooms then? Not that I've ever met one that actually meets the technical definition of macro (1:1 or better reproduction on the film/sensor) I don't mean to imply 'macro' zooms are all bad...

Dust Dust Dust!!! I hate it!
I hadn't noticed the dust at all until I looked from a slightly different angle!! The arctic butterfly is quite expensive...... I'm very paranoid about damaging the sensor or making the dust worse through the home cleaning stuff!

Just note that if you go the liquid option, be careful about which one you buy. I know of two choices; Eclipse and Eclipse2. The wrong one will damage the sensor coating. Other than that, nothing to doing it yourself. I have not heard of anyone with an ounce of common sense actually doing da...

K5. How do you rate yourself???
My issues with the K20, now being serviced in preparation for moving on, might just have something to do with its source. I am not as comfortable with it as my K10. I find the end result did not justify the upgrade. Perhaps it is all in the mind. regards Thoramay. Always interesting how p...

K5. How do you rate yourself???
I honestly believe there are some duff K20Ds out there. Not so duff that they don't work, but duff enough that the IQ is not good with them. I never got on with mine as I have said, as was constantly disappointed with the results. At first I put it down to a CMOS sensor over the CCD of the Ds, and...

Linux image apps roundup
DNG is an Adobe 'open' standard for digital negatives (RAW files). The resolution is unimportant as any DNG software can handle any DNG. No need for specific versions, and that is the whole point. You never need to worry about compatibility if a new camera supports DNG. I know it's open, I know it's...

Used DSLR values.
You had a similar situation in the 35mm days but it just was not as obvious as it is nowadays with the internet giving you a price comparison from your home. Nikon and Canon used to be seen always as the professionals choice, not because of their 'good lenses' or 'specialised lenses' but it was the...

Pentax EVIL - any rumours?
As title really, any rumours regarding a potential Pentax EVIL camera? I'd be happy if they just took the mirror out of a kx, added a pelicile mirror, added a mic jack, added a heat synch to the sensor, and an articulated lcd to it and called it a day. just keep the regular k mount. a couple more al...

Pentax EVIL - any rumours?
You do know that 50% of the light doesn't reach the sensor because of the pelicile mirror. For outdoor it would do but indoors it certainly has an impact :(

You do know that 50% of the light doesn't reach the sensor because of the pelicile mirror. For outdoor it would do but indoors it certainly has an impact :( I'm thinking with an all glass pentaprism, good high iso speed and a 25% silvered mirror you are essentially dropping the base Iso from 200 to...

Pentax EVIL - any rumours?
The split with Sony pellicle-mirror cameras is 70% to sensor and 30% to electronic viewfinder.

You do know that 50% of the light doesn't reach the sensor because of the pelicile mirror. For outdoor it would do but indoors it certainly has an impact :( And the Sony models which have it apparently suffer from crippling ghosting issues too.

Advice about monitor
At the moment I use a laptop for my processing but feel I will have to invest in a proper monitor if I want to get the most out of my photos. This is true since all laptop screens are pale and fuzzy approximations to what one really should be seeing. But how large? How good? How much money? For m...

Jessops
things looking up for pentax or are jessops finding it hard in this climate Bit of both I should think. The K-x really gave Pentax a boost from what I can gather and got the brand noticed .. especially all the different colours. Now they have carried it on with the K-r and the K-5 is getting peop...
