Replacing A Lost Hood
Did your hood have one of those little pull-out sections so that you can turn a circular polariser? That could account for the price. How about a rubber hood. If you get vignetting, then you could just cut round back of the rim to shorten the hood. Geoff

Wtd: Quick skip through shutter speeds in K-x.
Like you said, serves you right for buying a low end model camera :wink: With the K10D and the other advance models you've most of the shared function of the green button from the K-X under separate buttons. I wonder what happens to the settings if you switch from manual to Av and back again. ...

K5 review with high ISO examples
Have to agree with you Steve. It's a little hard to work out the point of focus, I think the end of the nose is about optimum, but I can't see any deterioration in noise from the first example to the last. In fact some elements of the highest example, eg the cats 'eyebrow' hairs seem to be better th...

K-5 Manual Online!!
Ricehigh is reporting issues with some k-5's. those that have should try to replicate and post back... now I tend to take Ricehigh with a grain of salt, (which should be followed by a shot of tequila and slice of lime).

Catzeye Focusing Screen delivery/cutms question..
Sorry I know not of UK customs/duties/import law but does your Govt not provide a public-info website covering all that? Or do they treat you like mushrooms over there? .R. Yes, all the info is public. An average amount from what I can work out is 20% plus I have heard of people being charged ...

Catzeye Focusing Screen delivery/cutms question..
Yes, all the info is public. An average amount from what I can work out is 20% plus I have heard of people being charged for opening and checking the package by the Customs people...? Thing is, if you don't get stopped, you save money, and they don't open everything, so that's the gambol. I just ...

Catzeye Focusing Screen delivery/cutms question..
I have a KatzEye screen in my K20 that I ordered direct from KatzEye last year (there are no UK agents as far as I know). Yes it is expensive and I was charged the import duty by the shipping company. I'm not able to compare it with anything other than the original screen so don't know if I could ...

Catzeye Focusing Screen delivery/cutms question..
As it happens I was fiddling about last night and fitted my home made [reduced in size] focus screen into my K200d and it appears to be working well. I made`this for my K100d but was never quite happy with it in that camera. I really wanted the *istDS for my MF lenses, but if this works and saves...

Doubts about the K-5 ??
One thing to bear in mind is that the non-sport photos were all taken with a DA*16-50 which (when the SDM's not on strike) is a lovely lens. Also, I'm not overwhelmed by the focus accuracy on 1, 2 & 5 ('perfect focus' is on the bloke's tie, the bride's veil and the sign respectively, rather than the...

Newer sensors worse results? (open letter)
will read thnx. on a related note, (complaints about camera manufacture) Ricehigh is whining about the red focus dots in the kr.... how many years was he nagging about the lack of red dots in the kx? oh, and something about the battery as well... I can't help but wonder... How many people i...

Newer sensors worse results? (open letter)
Lets get a few things clear: 18% gray was the old standard setting for light meters - and I speak of the 1950s and '60s, and your photographer then would meter off an 18% gray card at the subject position. That is, he/she measured the reflectance from the test card at the subject position. RG&B a...

Newer sensors worse results? (open letter)
i follow what's going on, but i'm still intrigued by this statement from mark dubovoy over at ll In fact, is not even clear that large aperture lenses will deliver a shallower depth of field as intended. The DxO measurements to date prove that the marginal light rays just don’t hit the sensor. Th...

Newer sensors worse results? (open letter)
the depth of field effects are significant, in my opinion. so what's going on there? perhaps out of focus areas strike the film plane more perpendicularly than in focus areas? i'm no optical engineer, so i can't explain. Isn't that the opposite of what he's saying? Marginal light rays being less per...

Newer sensors worse results? (open letter)
Isn't that the opposite of what he's saying? Marginal light rays being less perpendicular, they are simply not picked up by the sensor and therefore don't contribute to exposure or the softness and size of out of focus blur. However if this was the case in practice surely people would have notice...

K-7 startup is this normal?
Interesting, I'm not alone... did Pentax intentionally make the aperture churrk in their latest firmware update? With my pentax 18-55 and 50-200mm lenses, the churrk is not subdued. In some troubleshooting, I did determine that it was indeed the aperture solenoid causing the sound. But I go...

The K5 Experience
Thought it may be a good idea to focus all the comments from people who have actually GOT ONE, in a single Thread. So we can all benefit.:D
