Purple fringing - the cause?
There's a very simple experiment, of course, which would confirm it, if anyone has a suitable lens, and still uses a film camera as well as digital. I've been thinking about doing this for a while. I have a XR Rikenon 300mm f4.5 APO lens which is really quite sharp - but on my K200D generates l...

Best Holster for Pentax K5 and standard Zoom
Hey sorry to bump this post back up- Just wondering if a CCS warthog would be suitable for a Pentax K-5 with the DA 35mm f2.4 AL Lens? Or if not, can anyone recommend a case for this camera/lens combo? Thanks, Mike

Fungus
It depends whether or not you can easily dismantle it. I have succesfully cleaned a Takumar 135mm f3.5 that was riddled with it and it is now spotless. As for whether or not it will grow back or contaminate your other lenses, the answer is 'no' as long is it and your other lenses are not stored in...

Fried hard drive
Have you checked inside for burning etc. I had a similar happening a few years back with a Sony recorder (I realise that it's trivial by comparison). I noticed that a fine track from the power socket to the regulator chip had fused. Soldered in a piece of thin telephone cable (huge by comparison) an...

Dear Pentax Ricoh
longer lenses, a more accurate auto focus that will work in almost total darkness. a choice of bodies for eack model including one that doesn't have video, why should i pay for something i don't want, need or will ever use!

Dear Pentax Ricoh
Split prism focus screen option please for SLRs, then I might be tempted by the K5!

One Lump or Two
I have 2 DSLRs and a 35mm film camera. If I'm shooting things that don't tend to move I carry one DSLR and the 35mm and change lenses as I need. But if I'm in an environment where I need the versatility (such as the Goth Weekend) to be able to catch shots quickly then I put a wide zoom on one ...

Kenko CPL Filters. Anyone using them?
Anyone else have one? Are they harder to rotate than other CPL filters? I a 77m Kenko CPL when I bought my DA 16-50mm lens in late August, first time out with it I thought it was unusally stiff and difficult turn(couldn't turn it with just fingers - had to take off the hood and turn it like I wa...

Kenko CPL Filters. Anyone using them?
I have a 67mm one and it is stiffer than my Hoya CPL filters. You have to be careful not to unscrew the filter if you turn it anti-clockwise. My Hoya CPL's are a lot smoother, I have a Kood one which is quite stiff but not as stiff as the Kenko one. Regards George Thanks, I was beginner to...

Kenko CPL Filters. Anyone using them?
I have a 77mm Kenko Pro 1D fitted to a DA* 16-50 . It is slightly more resitive to turning than a 58mm Kood I use, but it is definitely not stiff. Regards - Steve I posses a range of polarisers of different size from Hoya, Sigma, Marumi and Kenko and I can't say I've noticed any great difference...

Shoot, then focus?
It is very interesting, and the interactive gallery is amazing. If my eyesight gets any worse I want one of them.

Shoot, then focus?
Ingenious concept. I've read the scientific small print. It appears that the trade-off with this technology is an inevitable loss of sharpness.

Shoot, then focus?
Yes I noticed that in the shot's that you can manipulate. If you you can click on the part of the image you want in focus.

Shoot, then focus?
Was reading a very similar amounement article recently. Beside the complete new way of capturing images, I wonder how the very unusual haptic will influence the way you take a picture. For me, one of the biggest advantages of a DSLR compared to a high class compact camera is the view finder shooting...

Shoot, then focus?
This is very interesting technology. However, if you read the inventor's treatise, you will see that it requires a 100mp sensor to give an 1800x1200px image which in turn needs a huge amount of software manipulation to make the IQ acceptable. Taking nothing away from it but it's a heavy price to ...

Shoot, then focus?
Interesting technology but they need better software as, from what I've seen so far, you can't change depth of field so everything is in focus, or part is completely blurred. Just select which bit you want in focus. I won't be hanging up my SLR's just yet........
