K5 vs. D7000 & EOS60D
Almost any lens will fit on a Canon because it's registration distance is small at 44mm.... Pentax is 45.46mm so no correction lens needed. Nikon is 46.5mm so a correction lens is needed for infinity focus with Pentax lenses. Good stuff. So the Minolta registration must be such that it needs a l...

'F--' K20D loses F Stop info
My K20D went back to Johnsons (via Clifton Cameras) last month as it struggled to focus at wide angle with both a DA*16-50 and a DA16-45mm. (Both these lenses too have been checked out by Johnsons). Another issue was that sometimes without warning the camera loses track of what F-stop is set. The di...

'F--' K20D loses F Stop info
Have you made the AF focus adjustments for those lenses? If you haven't, and they are both front focussing, they will have problems focussing at infinity. When I have had aperture control issues (rarely) I use one drop of WD40 on a lint free cloth to clean both the camera and lens contacts. Ot...

'F--' K20D loses F Stop info
Thanks Peter. Just to give you an idea of the hassle of sending this camera in. I took it with me to a weddding in Wakefield. Once I did the wedding (lots of MF when needed!) I had to ask a friend to post it to Clifton Cameras as I was going straight back to Spain. Then once it was fixed it had t...

'F--' K20D loses F Stop info
I can only offer my sympathy. I live in France and my K20 went back to the UK for repair four times. The fifth occasion they replaced it with a K7. The K7 arrived faulty (I think it was a customer return) - it doesn't recognise the lens (comes up with F-- as does your K20), plus other things. So...

'F--' K20D loses F Stop info
Just to share with you: My K20D sometimes cannot lock focus with the DA* 16-50, though it is very rare (just about 1% of shooting). Most of the time were focusing at infinity. And I remember one time I could not set the aperture (but I don't remember what lens I was using). But then everything turne...

'F--' K20D loses F Stop info
I went out shooting today (I have not yet cleaned the contacts since last weekend) and the camera behaved itself 100% with the DA16-45mm. It's the random nature of these 'F--' moments that can be so annoying. It must be the mount as I can switch the camera off, rotate the lens in the mount as if I'm...

'F--' K20D loses F Stop info
Just to share with you: My K20D sometimes cannot lock focus with the DA* 16-50, though it is very rare (just about 1% of shooting). I recently bought a DA 14mm /2.8 prime and on the K20D that won't lock focus at or near infinity. Works fine on the K10D though. I calibrated the AF but that didn't cu...

'F--' K20D loses F Stop info
Just tried one!! Success!!!! Works a treat. No more F-- !!! Going to emery the other two now. I suspect the ebay seller might have got rid of them because of this. I just scraped away a little bit with a knife blade. I think it was Mannesty who discovered this a couple of years back.

'F--' K20D loses F Stop info
I get the same "F---" on my mirror lens which is fixed at F8. It is attached to the camera by a T mount, which does not have any contacts at all. Therefore it would seem logical that the message is not getting through from the lens to the camera, either due to (a) poor conduction through the contact...

K5 - Live View functionality?
Yep, used it a few times now for tripod mounted work and proving very useful. To put this into perspective, I rarely bothered using LV (and certainly not AF in LV) on the K20 or K-x. What's more, aside from being fairly quick it really nails focus too: the following is a 100% crop from the low-q...

K5 - Live View functionality?
Live View is not a toy for me when we're talking video. It's something I want / need to be able to use when recording to confirm that focus sits 100% exactly where I want. The 7D does exactly this: press the magnify button and I get a 5x zoom. Even at f4 and 50mm, I can get the DoF EXACTLY where I w...

K5 - Live View functionality?
On the K-7 (and consequently the K-5) you just press the 'info' button to zoom in to the image. You have to keep pressing it to zoom in another increment, but there may well be a setting where you can leap to a 5x view, or whatever you want. The view gets very pixellated as you zoom in but you ca...

K5 - Live View functionality?
After a quick check, the zoom function in Live View doesn't seem to actually be available while recording on the K-7... :oops: Would be worth checking whether they have this on the K-5 though, or perhaps if it's a menu function I haven't enabled. What would be really good would be a small magnifi...

K5 - Live View functionality?
ha, that's even better. The 7D also won't zoom while recording, but I'm not that worried about that: I don't have to do follow-focus at the moment (though we really did work with focus today and definitely will again tomorrow) and that's where I see the HDMI output and / or focus pullers coming in.....

Best place to buy the K5?
Simon, I'd really consider using SRS and striking up a useful relationship with them. Their after sales support truly is as good as everyone on here says it is. They've looked after kit of mine that's broken down even when 2-3 months outside of the usual guarantee period. But then I have been a cust...

I want a K5...NOW!!
Father Ted , Beware -- a new kitchen could prove extremely damaging to your financial health :( Don't ask me how I know . Maybe there is a clue in the pictures you posted a while back of your new kitchen being fitted? :lol:
