Using Tamron P/KA mount on K100D
George, you are right, shooting like that can be tricky. The problem is that one shot is fine, and the next, taken a second later on the same pass, is drastically overexposed as Mike puts it, so that even a little tinkering in Photoshop can't save it. And that with the camera set to underexpose. ...

Luke Apologies, but these type questions continually pop up on various forums with no (or slender) facts to back them up. There are few certainties in life and the survival of any camera manufacturer is not one of them. You obviously appreciate the quality that Pentax is capable of as you ...

Like Stefan's comment proved for example Thank you Amin :D All ended well like Amin said, we all have a slippages of the tongue so...

I personally think you didn't exactly say anything wrong and if any member felt that what you heard were just silly rumours then they could have used decent and polite ways to refute it or enlighten you. I do agree with this. But spare a thought for the frustration of those that have had to do ...

Hi Luke Go out and enjoy using your Pentax kit. It`s cracking stuff, as good a value as any other make. It`s a fickle world we live in with companies coming and going, who knows what the future will bring. Your kit will bring you hours of pleasure and moments of dissapointment. Go and experiment ...

Going back to the original post...remember that..!!....I still think the question was perfectly valid. I'm a Pentax Man through and through. From my first Spotmatic 500 to my current K10D. I sincerely hope a Pentax Man I'll stay. But it's very frustrating to see dealers shelves full of Canikon and ...

As PeteL said: My feeling is that Pentax will be around for a good while yet though! It still has an enviable reputation in some parts of the world even if it has taken a back seat in recent years in English speaking countries. With regard to Pentax availability, I spend a good deal of time i...

Couple of lens questions
1. The 50mm F1.4 is a little soft wide open, but keep in mind focus is also very critical at such wide apertures. My 50mm 1.4 is soft wide open (though still nice for portraits), acceptably sharp by F2.4 and by F4 you could cut yourself on it. If you would like me to take some test shots to help you...

Focus adjustment
Looks like my K20D has slight front focus common to all/most of my lenses. I've tried a couple of focus charts/tests which confirm this. So, can anyone help me with these questions please? 1 For front focus is the camera adjustment + or -? 2 Is the amount of adjustment in-camera directly r...

Focus adjustment
You use minus amount for front focus, ie to get the camera to focus further back you need to use a minus amount and conversely, to get the camera to focus further forward, for back focus, you need to use positive adjustment. I do not think that there is any relationship between a focus chart and ...

Focus adjustment
Just a side note though but when doing this indoors under unnatural lighting (mostly yellow colour) the AF can be off outdoors since that's natural lighting so different colours. The AF use a beam splitter so it splits the light and every colour of light breaks differently, that's why we have rainb...

Thanks Stefan. I'm setting the adjustment outdoors as that's where I expect to use the camera most. That said, what's the colour temperature of flash? Daylight?

Most modern flashes are daylight (5000K) I believe. But studiolights are around the 3000K, and i'm not sure about that either :?

what's the colour temperature of flash That's only applicable if you are focussing with the flash (which isn't usual). It's more likely the AF will be working under tungsten or fluorescent lighting - with the flash for the main exposure. Just a thought ;) Matt

Thanks Matt. I guess the camera will use whatever light is available to focus before using the flash itself as a focus aid?

Lens Hoods and wat to pay
Hoods for zoom lenses are not as effective as they might be because they have to work at the widest setting. The perfect lens would have a zoom hood (like a zoom head on a flash) and retract as the focal length gets shorter. So given the case that most hoods are something of a compromise, I use ...

Pentax Colour
We've been working alongside some other photographers just recently and had a chance to have a long look at the different results from Pentax and Nikon cameras. One thing that did stand out was that the colour from the Pentax K20D cameras was so much better than from the Nikons. All cameras were ...
