I need advice, again
With my Pentax K100D there is a knob, on the top left, that you can turn for different functions for the Camera. One of them is the AV. :D I'm reading that if you turn to this setting, you can change the AV to smaller or larger focus. The higher the number, the more focus you get. The smaller...

I need advice, again
The higher the number the smaller the aperture, the greater the depth of field - ie the more of the photo is in focus, but less light gets in so the shutter speed is slower. The lower the number the wider the aperture, so more light, faster shutter speed, but shallower depth of field. Have a...

I need advice, again
Les. It's not quite as simple as just deciding how much of the subject you want in focus, though that is of course one of the factors for consideration, as there is the relationship of the holy trinity of Focus + Shutter Speed + ISO that comes into play with every shot. When you change one of them t...

This and this will help you understand how the aperture on your lens works. Hope this helps. The higher the number the smaller the aperture, the greater the depth of field - ie the more of the photo is in focus, but less light gets in so the shutter speed is slower. The lower the number the...

Problem with K-x flash housing
I wonder if any other K-x users have found this a problem, when the flash fires automatic I find I have to really slap the housing down and hold it for a few seconds, it wants to stay up, I took it back to Harrison Cameras in Sheffield and they told me it was OK ?? I think I must be doing something...

Problem with K-x flash housing
Trixie, I have not had any issues with my K-X, nor with my son's K-M which is basically the same body. On both our cameras it stays down with just a firm push and has never popped back up again.

Problem with K-x flash housing
Mine was pretty sensitive on my K-x and my new K-r is as well. It does go back and stay back but not always first time and there is no positive click to say it is locked back in. Dave

K-r magnified live view screen
I didn't use Live View on the K-x because the autofocus was painfully slow. The K-r seems better. I've noticed the focus area magnifies while focusing but it vanishes when it gets to focus so it doesn't really do much. In manual focus when I need it , it doesn't magnify and there is no focus confirm...

K-r magnified live view screen
Not sure on the K-R, but I have a K-X and have used the Live View Autofocus successfully. Also used it for critical manual focus in magnified view. If the K-X will magnify, I'm sure the K-R will. On the K-X you press the 'Info' button whilst in Live View and this increases the magnification on ea...

K-r magnified live view screen
I think what the OP wants is just the middle bit of the image magnified so focus and composition are checked at the same time. That would be very handy if it can be done.

K-r magnified live view screen
Thanks for that. It does magnify with the info button. Did look in the manual but not that easy to find and I knew you kind folks would know :D:D Now I've looked in the manual and can't see anywhere about the focus confirm symbol/bleep in live view with manual focus. Same with catch-in-focus, both...

K-r magnified live view screen
Now I've looked in the manual and can't see anywhere about the focus confirm symbol/bleep in live view with manual focus. Same with catch-in-focus, both only seem to work with viewfinder. I don't think it does that. The contrast AF used in liveview might be the limiting factor here.

K-r magnified live view screen
Mmm, a bit of a shame as I'd thought I'd found a way of shooting in macro with manual focus but the resolution of the screen magnified is way too low to be sure of focus with my (ageing) eyes.

K-r magnified live view screen
Live view on the KR can be set for face detect, contrast AF or phase difference AF which I think is better but requires a double mirror operation. It's not so much better more that they are differnt. The plusses for contrast AF is that it use the actually image to adjust the focus so there are no f...

K-x or K-r dilemma
I would take the first one. The 50-200mm from the twin lens kit isn't worth the extra £70 .. personally I would make do with the 18-55mm and buy a 55-300mm once funds allow. K-r is quite a bit better than the K-x .. has faster af, focus points, lens adjustment and a few extra bits .. plus 12 mont...

Just picked up the k5
Just came back from a quick shoot on The appian way just out of rome. Absolutely amazing camera. I had no idea even of the potential of my 16-50 sdm until attached to the k5. My worries in the past with thi lens being slow and unsharp in auto is over. I can't wait to check out the photo on my mac. S...

Kr - AF Fine Adjustment
Yes using spot focus and very careful to focus on the light bulb. But I have a feeling that ff and bf issues which seem to arise with the Kr may have someting to do with the accuracy of the spot focus. Will have to retest outside with a focus sheet and a tripod.

Kr - AF Fine Adjustment
Always looking for the sharpest possible photo. Under the Custom settings No 21. Does the fine adjustment only affect the current lens, or any lens attached to the camera. Taking pictures of a light bulb inside, with the built in flash using the 55-300 pentax lens. The bulb comes out sharp at th...
