Movies with the K7! Where do i start?

Some really useful comments there. SO... I'm going to use my Pentax 50mm or Sigma 24 mm which both have an aperture ring. I will change aperture on the lens. The clicks don't matter as i'm adding music/sound recorded effects later anyway to my film eventually. Oh yeah i'm making a short arty film...

Wide zoom for Kx

(IQ =) Image Quality, yet another abbreviation in common use. It's a good idea if we write it in full the first time in a post and then thereafter as an abbreviation as not everyone will know what's meant. It's always a good idea to write out in full on first mention. Most scientific journals insist...

Is it Goodbye to my K10D

Hello Mark, the battery is charged, strap fitted and memory card formatted. Instruction manual is open and I have managed to set the date, only one pic so far. My last mug of tea in a multi coloured one. Very impressive and the AF speed is awesome. Expect it will rain tomorrow. The IQ of the K10...

How to kill the FPS of a K7 :-(

Morning all, Thought I'd post a little warning/hard won experience for you all! I've just spent a happy weekend at Silverstone watching the FIA GT1 World championship. All going well until the moment I found a good position and started burst mode shooting of the cars - The K7 seemed to have devel...

How to kill the FPS of a K7 :-(

I had the same thing happen to me a while back. I was, like yourself, fiddling in the menus and found that one too and thought that's a good idea we'll have some of that. The next time I was at the karting my burst mode was like a three toed sloth...with rickets! Luckily I realised it had occurred a...

Shooting an Infrared Image

Greetings from the USA. Without going into a whole lot of detail, I tried using a cheap IR Filter with my K100D a while back. Never could get the hang of it. Pictures came out darn stupid, so I stopped trying. Would using a Hoya R72 Filter make any difference with my K100D or do you have to ...

Shooting an Infrared Image

I would guess that the K100d would be partially sensitive to infrared. To use an unmodified camera for infrared, mount the camera on a tripod and frame and focus the subject. Set f8 at 1/8 sec, screw on the infrared filter and take an exposure. Repeat taking exposures at different shutter speeds un...

Shooting an Infrared Image

Also bear in mind that the focus will be different with IR light so if you are relying on autofocus it will be out. Some older lenses have an IR focus scale but otherwise you might want to manually adjust the focus by trial and error after you have the exposure right.

Shooting an Infrared Image

I would guess that the K100d would be partially sensitive to infrared. There is a filter infront of the sensor that filter IR out sadly :( I've the same problem with the K10D but if it's a sunny day and you got a tripod you can do IR photography but it takes quite some long shutter times. The K10...

Shooting an Infrared Image

Getting them properly in focus is more of a problem, as IR focuses at a different point then visible light. This difference varies considerably from lens to lens :( I thought you could just focus through the filter now that i think about it?

Shooting an Infrared Image

OK, K10D and K20D - very poor for IR. K-r and K-5 very good for IR. This of course relates to using the cameras as-is and creating the IR effect in Photoshop. As for focusing proper IR through an R72 filter, lenses are not corrected for IR so the focus will be quite some way out. IR correction ma...

Shooting an Infrared Image

The K-5 live view does have enough light to give an image in bright conditions, but it is hard to see the screen in those conditions... I haven't found any situations where live view autofocus works through an R72 though. Live view can be used to focus manually. Normal autofocus often seems to ...

Shooting an Infrared Image

Les, I have been taking infrared images for quite some time with my K100D Super. Basically a K110D. I use a Hoya R72 and the standard 18-55 mk1 kit lens. This lens performs well with no hot-spots. I have also tried the 18-250mm, but this does seem to suffer from hot-spots. As mentioned previously...

lens hood for pentax kr

Welcome to the forum. It might be a very stupid reply but the lens hood is for the lens and not for the camera and since you can put different lenses on the camera you will need a different lens hood for each lens. So... we need to know the lenses you've with the camera? You proably will have...

With or without battery grip on K5?

I've never used a grip, even with huge lenses like the Bigma I have never felt the need for one. I just carry a spare battery or two with me. I have big hands for a woman, but smaller hands than most men of course. If you feel comfortable holding the camera as it is, then I wouldn't bother with ...

A dot in photos of my K-5

Hi. Thanks guys for your replies. Then, what will be the best way to sort it out. Who will be the best line to contact? Thanks for your help. Do as the law of the land says, take it back to the dealer you bought it from.

A dot in photos of my K-5

Looks nothing like any stain I have seen .. and I have sent back 2 K-5s with staining. Looks like a lump of crud to me but it would be nice to see them in a decent size to be certain.

Kx or Kr anyone?

It's a while since I last posted on this site - about 2 1/2 years by my reckoning. The truth is I sort of lost interest in photography for a number of reasons amongst which was the weight and bulk of my K10D. After lugging it around Canada for three weeks and around New Zealand for four weeks, I r...
