Not a dirty sensor
Well, it is not sitting right on the sensor. It is sitting on top of the filter (i.e. the surface of the sensor assembly) and therefore a little bit off the sensor. At wide apertures more light can go "around" the sensor, therefore softening the shadow. Yes of course. I'd forgotten about the filte...

Kit lense shade
Terry, I agree that the supplied lens caps are difficult to manage with the hoods in place. I've replaced mine with good quality center-pinch caps (if that makes any sense). This way, the hoods stay in place (only come off to change filters (I only tend to use polarizers - actually making u...

Specs for Flash and DA* lenses announced at Photokina
has been updated with the specs of the 60-250 and 55 DA* lenses and for the AF160FC ring flash. In particular it gives the range of filter thread diameters to which the ring flash will fit - I hadn't seen this else where before Good luck Bob

scratched sensor
Hopefully just the filter, as they should be "replaceable". (I believe places will replace them with IR filters for IR photos. So repair should also be possible). Although likely less than replacing the camera or the whole sensor assembly, I would guess the repair is not going to be "cheap".

scratched sensor
It could be that the sensor filter is just marked rather than scratched. A firm cleaning will get it off if so.

K20D
I've always assumed D-Range would be processing applied to an in camera jpeg, surely RAW is raw? :? Not that I've looked into it at all, not having a K20D... :roll: Dan No the K20D has a filter which can be applied to jpegs in camera, but D-range works with RAW. I haven't yet done any tests to s...

Exif data format for K10D
PS CS4 can filter by any/all the EXIF data, by default it shows Focal length (thats the actual focal length selected if using a zoom), Aperture, White balance, Exposure time, Colour profile and the Raw converter settings (if named and saved). Any EXIF parameter can be added/removed to/from the list....

K20D vertical banding
Okay then it's all good Prieni :) but still you need to look at the lanes those are the source of the problem directly or indirectly, atleast without them you wouldn't have had it. Since I don't have Silkypix, I've tried some stuff with Photoshop on your crop and Filter>Noise>Madian seems to do ...

K20 D Lens
I agree - I have the Tamron 70-300 macro and a Samsung 50-200, and I'm happy with both, except that with the Tamron, the filter end rotates during focussing - a bit annoying when you are using a polarising filter.

K200 vs D60
Yes, Matt, I understand what you say, but recently i've been shooting with K10, grip (full), DA* and flash, and the second body around the other shoulder. So I am not sure that a D700 outfit would be much heavier. I am not very concerned about the "uncomfortableness" of the camera I use, and ye...

I have a few lenses all with hoya filters on the front as you may notice from my gear i am a bit anal that way i like everything to be the same:D .I...

Personally I don't use filters for protection, some here feel the same way, others don't. If you're going to use them, then it makes sense to buy the best you can afford. If you have the lenshood fitted all the time, it will protect the front element of your lens from knocks and scrapes much bette...

The only filters I use are polarizers and ND grads, none for 'protection'. If I protect my lenses at all it's through careful handling and mandatory use of the lens hood. My argument against fitting a 'protective' filter is simple. Why spend several hundred pounds on a lens which has very expensi...

lens care
I do put filters on the front of all my lenses, The reasons are as follows: 1) My bag isn't big enough to leave the lens hoods on permanently. Have you seen the size of the 50-135mm one? Also, the hood of the 12-24mm looks a bit fragile for that sort of treatment. 2) I am cack-handed and am alw...

I do not use protective filters because of: A: Cost B: Im pretty sure putting anything in front of the lens is going to cut down on incoming light to some extent. C: Once saw a lens after someone had dropped it and the filter smashed against the front element ... not a nice sight. I do alway...

C: Once saw a lens after someone had dropped it and the filter smashed against the front element ... not a nice sight. I dare say the front element would have still looked pretty horrible had it smashed into whatever instead of the filter. Surely any bump bad enough to break the filter would leave ...

Generally, I have always put on skylight or UV simply to protect the front element from sticky fingers and dust.... But with my recent purchases? no I haven't simply because I have noticed how on some lenses the image degrades so much I have actually questioned the lens itself.. Once I removed th...
