Lens Hood for Pentax K-R DA-L lenses
Nah, Nov-Dec is normally the rainy seasons here. But it also depends on which part of KL/Malaysia you'r going to be in. Anyway, the world weather has changed, so let's hope you won't get wet while in KL. As for you being in Yangon from Dec 8-10, looks like I won't be able to meet u too, cos I'll...

Image quality of a K-5 vs a K-r
I really like the images produced by the K-r. The weaker AA filter makes a difference to fine detail and the image quality is excellent. I went for the K-5 though because of: Magnesium alloy body AF micro-adjustment Weather sealing High capacity battery Additional controls Slightly better no...

Best Pentax DLSR and lenses for travel/street/reportage.
Interesting Darryl. I could accept that explanation if it was no photography at all, but it is a specific ban on DSLRs. P&S cameras, phone cameras, film SLRs, system cameras. All allowed, but not DSLRs. Many of these have image quality as good as, if not better, than say a intro level DSLR with ...

ir filter on k5
Whilst the K7 is not a good choice for IR (it has a strong hot mirror, which will almost certainly also apply to the K5) it can still do IR. I've not yet done a relative IR sensitivity check between my K100 & my K7 but I plan too sometime. I've only done a small number of IR shots with the K7 - ev...

ir filter on k5
My filters are just cheap Chinese E-bay models (they actually say Green-L on them). I've got a 760nm in 49mm size (for the F50) & 720nm & 860nm? in 52mm (for the kit zooms). IIRC they were under £15 each delivered, so it's not to expensive to try one out.

Simulating Film types on K-5
Thanks Riebleu, I should have added that I have FilmPack, so can use it as a guide. It's a pretty good package, especially the simulation of my favorite B&W films (Tri-X and HP5). I work all day using software to process imagery, (my main employment is teaching creative industries courses up to BA ...

Simulating Film types on K-5
So far I have a User mode for a bright transparency film (1) look which seems good for product shots and studio work, and a general purpose 'grainy B&W' (2), but which still needs some work. Inspired by this work I'm working on a pale colour and flat tone effect today (3). (1) Reversal Film, ...

K5 my new Christmas present
The one thing I dislike about getting new cameras is fitting the strap....it needs a quick release system like the Rollei TLRs used to have. Hmm.. As long as it's not like the quick release that let one of our Spotmatics fall off its strap some years ago! One of the spring clips opened, and the ca...

Sensor Cleaning Pentax K-r
I have mine set to shake the sensor on startup. Feels a bit violent but it didn't harm my old GX10 and seems to do no harm on the Kr. I used to use a rocket blower to clean out odd bits of dust - but I had a bit of a disaster with one a few months ago. The blower got some dust in it - so instead ...

K-5 video hotspots work around (fixed)
As far as I am aware, dust cannot sit directly on the sensor due to the filter. Any dust in front of the sensor will only block light and therefore will result in a dark spot. Only leakage currents can cause 'sparkles' (or hot pixels). I'm no expert, so I may be proven wrong about this.

K-5 video hotspots work around (fixed)
Pixel mapping is available on the cameras and the "hot pixels" can be mapped out of existence. Dust is dark specks and these lie on the low pass filter that covers the sensor.

K5 help
Thanks for the help. I was concerned that my camera had a fault, even using an f2 lens had the same result.Its almost as if the camera is saying use flash, but i cannot find any reference to this in the manual. Regards Rick It's here: Exposure Warning If the subject is too bright or too...

Possible K-5 WR problem
Are there one-way vents to deal with this air movement? Just my thoughts. In my mind, there need to be some sort of vents, but i my mind, it should be through a filter of some kind. and not at the thumb wheel....

Cleaning sensor Kx
You can clean the sensor with a pec pad slightly dampened with isopropyl alcohol - it must be damp, not wet. Bear in mind when doing this that you will not be touching the sensor as it has a filter over the top of it. Make sure there's no dust on it first (use a blower) and wrap the pec pad around...

Thanks for all your help, I sold it for 195 in the end, inc a cheap 4GB card and lens filter, so not too bad... saves on the hassle of advertising etc... quite emotional letting it go initially , my first DSLR ... awhhhhh

Faulty lens or ...?
Well done Chris for finding it. I can't see it at all on my reductions. It would be unusual for dust inside a lens to cause something like that. Something on a filter in front of a lens might but then it would only normally show up on a wide angle shot where the depth of field is large. Could it ...
