Shooting in black & white?

Been on Nikon manual SLRs for a couple of decades but never got a feeling for their DSLRs. Somehow with the K20D I feel at home :) but it feels a bit weird to think colour. It took ages to be able to think b&w...the arteries of change has begun to harden :) I'm looking for that shot at Dagenham....

K7 or 31mm Ltd Dilemma

Just had a thought... wait and see what the IQ turns out like on the K-x:?: If the new sensor is as good as some predict, you might get what you are after in a cheaper package.

K-x ISO 1600 shots

Perhaps Pentax will move back to Sony sensors for a K7 upgrade? strangely, Sony's full frame cameras get a bad press for sensor noise.

K-x ISO 1600 shots

Are these RAW or jpegs straight from camera? If they're RAW, any idea how they've been processed? I think these need to be answered before we either write off the K-7 or herald the K-x as the successor to the D3. :lol: As we've seen from the DPreview review of the K-7, there's really not any di...

Pentax *ist D S dslr

Hey everyone, im new on here and need some advice on the *ist d s camera, i.e lenses tht will fit and flashes, remote control, and any adapters that i could use. Welcome aboard. The DS's sensor is a real beauty. My first Pentax DSLR was the Pentax *ist D which uses the same sensor as the DS and I...

Pentax confusion

I guess I don't like change.-hmm If it aint broke why fix it,progress eh.Why stop making a successful product like the K20 and KM? Toyota stopped making the Corrolla, one of the most popular cars ever produced-must be the human condition.:D Goodnight all Chris:D I don't know about the K20 bu...

DPreview K-7 review

Page 26: Shooting in RAW format and processing with Adobe ACR 5.4 squeezes some extra detail out of both cameras' output. Using the 'equalized' ACR processing and considering the K-7 and K20D are being built around a very similar sensor it does not come as a surprise that there is not much discer...

Worth investing in lenses?

Now people have told me that pentax are likely to stop making high end bodys, is this true? They are coming with a MF digital camera Spring 2010, I believe that you can call a MF high-end :wink: Not even Nikon or Canon has such a large sensor only FF, they are such amateurs :wink: :) The 645D wi...

Worth investing in lenses?

Thirdly, please do not be put off by any harsh comments, you will find that there are a lot more members who take a more understanding view to a question such as yours. 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...

Favourable in-depth review of the K-7

interesting that the RAW noise comes out higher than the K20D, I thought the new sensor was supposed to have lower noise than the old one?

K20d D range optimiser

I guess you mean Dynamic Range (page 79 in manual)? It expands the sensor's dynamic range (or it should). The only effect I noticed I had much more noise, particularly in dark regions, even with low ISO set, so I happily switched it off and never used again.

Pentax Colour

Can definately agree to that. We got a copy of the shots that the 'pro' photographer took at our friends wedding (D200) and compared them with ours and our conclusions about colour were the same, quality was better too! Every time I think about changing to a different system, I take a quick l...

K20D post shoot processing times!!!

The shutter will operate up to 30 seconds, meaning at worst a 30 second delay for the dark frame exposure. Does anyone know if noise reduction is active on "B" or not? I'm not sure that these sort of cameras are best suited for exposures of many hours. The sensor might get very hot and noisy in t...

K20D post shoot processing times!!!

Does anyone know if noise reduction is active on "B" or not? I'm not sure that these sort of cameras are best suited for exposures of many hours. The sensor might get very hot and noisy in that sort of time. It certainly is - I've done 10 minute exposures with a 10 minute dark frame to follow.

K20D post shoot processing times!!!

Ahhhhhh. Thanks for that explanation. Makes a lot of sense. Well apart from the fact noise is random so how would you use a second file of just noise to cancel the noise from the original shot? I'm an experienced audio editor and I know that if you subtract noise from noise you get noise. What am I ...

Yet more on ETTR with a Pentax K20

Well the RAW vs JPEG argument could rage for ever, but in the end it depends on what we produce and not how we get there! The relative merits will change all the time as technology advances. As regards colour space, i wonder how the result is affected by the fact that the cameras themselves do no...

Pentax K100 Battey Problem

A week or so ago someone had a similar issue. They cured the issue by careful cleaning of the cameras battery contacts. Cedric

K10 exposure query

Actually as the shutter uses current to keep open, there is a limit to the B setting - the amount of battery charge that is possible and how long that will sustain an exposure for. For film cameras using Lithium batteries this is probably 10 hours or so, but I've never seen a figure for DSLRs. I ...
