Panning focus/blur question
Thanks for those thoughts - if nothing else it's good to know that it isn't just me that (should be) binning a fair number of shots. Peter, that shot is what I was trying to achieve - pin sharp vehicle and blurred background. Even my good shots are good when cropped, dropped to 800 pixels and ru...

Panning focus/blur question
I was editing my post above when you posted yours Mike. Read the amended version. If you are using SR turned on, that might be the cause of your blurry images.

Panning focus/blur question
I was getting a lot of poor quality/blurry images when panning and eventually realised that this was often due to the camera shake reduction not having stabilised. This can take up to a second, and it is unlikely to stabilise whilst panning. Nowadays I turn off SR for this kind of picture, and get m...

Panning focus/blur question
When I said shake I meant movement relative to the car. Gwing's reply explains it much better than I did.

Panning focus/blur question
I love the first photo, Mike. I was at Donington yesterday and suspect I don't have any Firenza shots of even remotely parallel quality. There's some good advice above about deactivating in-body shake reduction - and panning is a hit-and-miss technique (mostly miss, in my case, but the hits somet...

Panning focus/blur question
Thanks Peter - I saw your second post, edited mine to add about the Sigma lens, but didn't see your edit. I had never thought of turning off shake reduction, but will try that next time. Simon, thanks for the note about AF - I think that's probably what I meant about the equipment not being up to...

Panning focus/blur question
MIke, the catch in focus system only works with manual focus lenses, or lenses that have an MF/AF setting set to MF. It won't work with AF lenses even if the body is set to MF.

Panning focus/blur question
Yes, I think I remember that - I used it with my Tamron 500mm mirror but I'd never looked at the zoom, now I look it doesn't seem to support that. Looks like there was a good reason for keeping all my old manual PK lenses after all!

K7. White balance
It is controlled from the menu item 'Memory' - this sets the defaults that will be reverted to every time you turn on the camera, and includes White Balance, Drive Mode, flash mode and many others. You go through the items one by one and tick the options you want to 'hold' in memory to be set wh...

Pentax-F 70-210 focus problem
Hi I recently purchased a second hand Pentax-F 70-210 which I have been delighted with until it developed a problem focussing. It works properly if I am focussing on a subject nearby. However if the subject is further than ~ 20feet the focus never locks i.e. the focus confirmation light in the v...

Pentax-F 70-210 focus problem
Are you sure you are focussing on something the autofocus can lock on to? that is something with pattern or texture. I cant see how it wont focus manually.

Pentax-F 70-210 focus problem
Hi Ken I suppose the best way to describe this is that it won't focus on infinity. The lens locks on focus fine as long as what I am focussing on isn't too far away. I recently used it to take images of "The Rat Pack" at The Playhouse,Edinburgh. Took several hundred photos in a few hours wit...

Pentax-F 70-210 focus problem
Hi Ken I had a Tamron 80-210 ad2 lens that I part dismantled to get rid of some fungus. When I reassembled it , it wouldn't focus on infinity. The front element screwed into the barrel and I had not recorded how many turns I had used to unscrew it. I removed the three screws in the barrel that...

Pentax-F 70-210 focus problem
I just can't see the 3 screws referred to. Normally they live underneath the rubber focus ring ;) It's been a long time since I had the F70-210, but the images of the FA80-320 may prove helpful: http://www.photon.me.uk/pu/pentax_fa80_320/index.html Look at the last image particularly - there's...

Pentax-F 70-210 focus problem
Good news! Have got the lens working again and it thankfully wasn't too difficult :) However I would like to thanks MattMatic and screwdriver222 for your your research. Have to admit that screwdrivers comment re "googling" made me smile! How many times have I suggested that? Funny how I didn't t...

Dead Pentax-DA 55-300mm f/4-5.8 ED
Oh calamity.... The good lady in my life has managed to completely seize up the 55-300 I gave her, Can't focus, can't shift the zoom either, so I guess a trip to Johnsons is the order of the day...... I suspect that while the lens was "safely" in the base of her camera rucksac, she's dumped it d...

Dead Pentax-DA 55-300mm f/4-5.8 ED
If it's broke I doubt you'll make it any worse by trying to rotate the focus key-way on the mount. You never know, it might unjam.
