Repair Centre For my K1
Coincidentally I have also had a problem with the shutter on my K-1. First press of the release button does not fire the shutter, and it takes a few attempts to get it moving, the problem started to happen at around 20k actuations, well within the rated specification for the camera. After a w...

Repair Centre For my K1
My K-1 also has the same shutter issue, but it is very intermittent and seems to be geting better, not worse. When I bought it 6 months ago it only had 4,000 shutter actuations and would not fire the shutter on the first shot after turning it on, but every subsequent shot worked. The issue has bee...

K3 - Manual focusing
You can use a "focus trap" with manual lenses. You set the shutter to operate only when the suject is in focus, then you hold the shutter button down. The shutter will then operate only as your suject comes into while you turn the focus ring (not too quickly, otherwise the sensor won't have tim...

K3 - Manual focusing
I did try a replacement focusing screen in my K-50. This has a circular diagonal central split screen area which was surounded by a larger microprism circular area. The split screen and microprisms certainly worked just like you had with film SLR cameras. However even when focus looked perfect with ...

Minimum Focus Distance K-5 vs K-1
The DA 35mm macro is designed for Pentax crop sensors, not full frame. However, as MikeInDevon has shown above, it will cover a full frame sensor but with light drop-off outside the area of the crop sensor. The minimum focus distance will not change, it is a property of the lens not the sensor or ca...

Minimum Focus Distance K-5 vs K-1
I would have thought the full-frame lens would be more expensive than my current 35mm. In the UK, the 50mm macro (full frame) is 33% cheaper than the 35mm macro (crop sensor). I have no idea why! Steve

F*$#@&G CAMERAS!!
AF issues would be my single biggest peeve with a dslr, and would be the main reason I’d consider mirrorless. The number of times my subject is front or back focussed and has ruined my shot. Eye AF would be especially handy with the sensor seeing the actual lens focus and adjusting instead of needi...

What camera would be optimal for shooting product images of leather jackets?
I imagine you'd be using some artificial lighting so it doesn't really matter as long as it's reasonable modern. For general use and also small details I'd say the DA 35mm f/2.8 Macro Limited is the best choice. It's a great lens and compatible with any Pentax DSLR with an APS-C sensor (or on a ...

What camera would be optimal for shooting product images of leather jackets?
To be honest - any DSLR made in the last 10-15 years will do. Just look at brochure of the Nikon D3 launched in 2008 you get stunning quality from a 12MP sensor. to print to A3 size. If you want to print bigger then a higher pixel count will be required, not too much but anything with minimum 20...

K-1 Mk3 in development, so Ricoh say
and the Facebook pages are alive with rumours and speculations, and the usual arguments. With feet in 2 camps and no intention of going mirrorless anytime soon, I am interested. I bought my K-1 in 2016, shortly before getting a D810. For some strange reason I could not feel satisfied with the D...

May I ask for some guidance please
Anything from the K-5 II onwards will be fine. Bear in mind that anything other than the K-1 or K-1 II has an APS-C sensor, which is half the size of a negative from 35mm film, and results in a 1.5x change in the field of view for any lens, so a 50mm would have the field of view of a 75mm lens etc....

From KP to something smaller?
Smaller cameras tend to have smaller sensors, so nearly rules out anything APS-C. Personally I think the best fixed zoom lens travel camera is the Lumix LX100 & II or its Leica variants Typ 109 / D-Lux 7 or 8 (M43 sensor). I guess a Pentax solution is to stick with your KP and get the 18-50mm f/4...

From KP to something smaller?
The Ricoh GR range will give you the same image quality as your KP and is truly pocketable but has a fixed lens. If you want a small camera with a zoom lens you will be looking at a smaller sensor, with image quality not much better than a decent phone. I'm not sure what is currently in production. ...

From KP to something smaller?
Sounds like you have a keen eye for quality results, although the format of the WG is really practical and pocketable, it's not going to match up to the results of an APS-C sensor as you pointed out. The GR is really your only choice within the Pentax/Ricoh arena with the size constraint and desi...

From KP to something smaller?
The GR (III) is perfect as a travel camera. The IQ is insane and it fits in your pocket despite having a proper DSLR sensor.

Canon EOS 5D
Apparently the Canon 5D is actually real. It brings 13 megapixels in a 36mm sensor (popularly known as "full-frame"). But with almost a kilogram (900g) of body weight with battery, no built-in flash, a viewfinder that doesn't seem to be anything special and no AF assist, I have no desire to own one....

Adobe DNG Converter and Camera RAW plug-in
I can't really think that there is any hard-wired circuitry involved. The hardware in most cameras is the same generically. Ignoting the CCD or CMOS sensor, there is a piece of wizard electronics that converts an image to bits 'n bytes, these are then passed to software/firmware for further processi...

Basic Colour Management: C1 & PS
In response to some other threads, I thought it appropriate to give a little guidance on the way you should set up a Windows machine for colour with Capture One and Photoshop. First of all, you need to decide on a colour space you are going to work with (as a rule). I suggest one of three: Adobe...
