KP review in Outdoor Photography
Excellent Magazine, they just do one review a month and the rest is all about taking photographs. I was lucky enough to be bought a subscription for Christmas. When it runs out I might go for the half price digital option on my tablet. Everything I've read about the KP leads back to it being ...

KP review in Outdoor Photography
Recently made the decision to get a KP and a 16-85mm lens. Had rented this kit before and enjoyed it. The 16-85mm works quite well compared to my 18-135mm. Comparing the KP the the K-3 isn't a complicated en devour. The co-processor of the KP allows for sensor information to be more accurate ins...

KP review in Outdoor Photography
Good Review by Daniel who is a mod on this forum :mrgreen: -- Not so much (being a mod I mean, he is a good chap to do reviews!) anymore, he left funnily enough after reviewing the K-3 after the response on this forum from one or two members and lack of support by the main moderator when it happ...

KP review in Outdoor Photography
Did someone mention my name? :D I have been absent for quite some time, and really clearly shouldn't still be shown as a Mod any more. I don't think it was any one thing that caused me to drift away, mainly the over all tone of the forum at the time, and just wanting to spend less time at the co...

It works for me on Win7, 64 bit albeit slowly. There's an old thread about this issue See if that helps and report back!

Viewing an image file in K-1, does it display every pixel?
At the 16x magnification there didn't seem to be too much difference so I wondered whether the complete JPG was being shown on screen. When checking your picture for focus accuracy/sharpness immediately after taking it, you should use 100% view, no more. This is 10x on the K1. You can set the zoom c...

Focusing issues on Pentax cameras
Hello, Has anyone had any focusing issues on Pentax cameras? I have had a Pentax K5 for some time now and have found my sharpness hit rate has dropped, even when using a tripod. So I bought one of these Camera/lens calibrator card kits, which sit on top of a table at an angle with a flat pl...

Focusing issues on Pentax cameras
Agree with john and Jon..... get the AF tuned and you will notice a difference. Larger and larger sensors means we can see the limitations of AF systems on cameras more easily. When you do your AF tests..... Tripod/test chart/natural light if possible. Use the widest aperture only to do the...

Focusing issues on Pentax cameras
Thanks for advising about the fine tuning option. I didn't have a user manual so was unaware about that option. I have now downloaded a PDF user manual and will follow the instructions and hopefully get my lenses to focus correctly. I noticed the most recent images of wildlife was not always shar...

Focusing issues on Pentax cameras
The tests I did a couple of years ago with the K-3/K-5/K-30 showed that several Sigma lenses had back/front focus issues with some of them - and that, in the end, that the K-3 was itself not correctly calibrated and had to be serviced by Johnsons (but that's another rather less-than-satisfactory sto...

Focusing issues on Pentax cameras
FWIW, you don't need to buy any special kit to do the adjustment - just get a 1m aluminium rule from your local DIY place, put a piece of masking tape on it to indicate the 50cm point, and set it at around 45 degs to the vertical at a suitable distance (will depend on the lens in question - I used a...

Focusing issues on Pentax cameras
What's the vibe on distance to the subject? Do the results work better if it's up close than further away etc? And What's the consensus around zoom lenses? If you have a 55-300, where does one look across the focal range to undertake this test? I use 3-5 metres away for lenses up to say 100mm ,...

What you focus on should be parallel to the back of your camera. This cheap chart from Amazon looks good at £4.20 for two.... --

Focusing issues on Pentax cameras
PS: did anyone mention that you need to do the tests with the camera on a sturdy tripod with a head that can be firmly locked in place - otherwise you will never keep the single AF point on the target I suppose technically you're right, but isn't how I do it! I normally hand hold the camera so if I...

Focusing issues on Pentax cameras
You can't be sure that the RED X is exactly over the detection point, or that it doesn't lock onto something nearby, that's why you need to focus on something parallel to the camera back. It's also easier with a tripod with a focusing rack. Most of my tests are MF based on the BEEP. There's usual...

Focusing issues on Pentax cameras
If AF works the same as the BEEP does in MF then it only works for the distance you test it at :oops: That's because it works similar to DOF and BEEPS as soon as it enters the nearest or farthest point. Not of much use to a photographer :cry: -- That is a criticism of autofocus systems in general...
