170-500mm Filter for Safari?
If you want this for the proverbial lens protection properties there are many threads on the subject with argument for and against, if you want it to cut down on UV then your wasting your time, your sensor already has one. Either way you need to buy the most expensive you can afford, cheap ones w...

170-500mm Filter for Safari?
I'd spend less money on a secondhand fast prime instead. Something like a 50mm/1.7 would supplement the Sigma really well for landscapes/sunsets etc and be of much more benefit than a filter on front of your lens - just keep the hood on and cap when you're not using it. On safari in Botswana a c...

170-500mm Filter for Safari?
Don't think there is any filter that would be of any benefit. Most important thing to do is to protect the front face of the lens - use the hood, keep the cap on when not in use as Jon says + have a rocket blower in you pocket to clear any dust. Better than a cloth. A second body with a comple...

170-500mm Filter for Safari?
Thanks all for the advise, very useful. I was more thinking to try and reduce the glare with the filter but agree that a protector may be best. Am having all sorts of dilemas at the moment ref which bag to take with camera in as well. Cheers again for all your help

What you might want to do is take and ND grad for sunsets. Cheap Cokin P type mount off ebay, and something like a KOOD pro shouldn't break the bank but provide new functionalities. Dust protection is really the only use I can see for another filter. The rocket blower should take care of most du...

170-500mm Filter for Safari?
Been twice in the last couple of years. First year's dilemma was which lens. Opted for FA*300 and FA 50mm Macro. No filters just a good lens blower. As for the bag, I used a Currys special as it sat flat on the floor of the jeep and was easy to access the camera when needed (Most of the time) bu...

170-500mm Filter for Safari?
Our Tanzanian guide recommended a sock over the lens - quick to whip off when you need the camera and pretty good at keeping dust out meanwhile. Also you don't lose the lens cap then as it stays in the bag. I used my Sigma 28-300 on safari, with my Ds. No other lenses to reduce dust, and no filters...

To the people who love manual focus...
I tried one of the cheap Chinese screens and wasn't impressed, it's just too dark (especially with a filter) and the split prism bit is too big for APS-C as they're cut down from a 35mm screen. I've changed back to a standard screen and turned the in focus beep back on. Given that my favourite ma...

*istDS to K200d
Do what I do Andy - dedicate it to M42 lenses as I have with my *istD - I then have instant access to about 12 lenses and the bellows and the tubes and teleconverters all with screw mounts and great quality. Or infra-red, I believe they don't have a sensor filter that cut infra-red so much as the ca...

*istDS to K200d
Thanks for all the suggestions and comments,. Re infra red..is that a case or using a filter or is there more to it? I have seen some 'converted' Pentax DSLRs on Ebay. Would the *istDS be a good camera to put a split focus screen on and use for MF, I have a selection of lenses that fit the b...

For infrared, the 6MP bodies are all more sensitive than the newer cameras. You can use a Hoya R72 filter on front of the lens, and the kit lens is perfectly adequate for IR photography - not least because you'd probably be shooting in its sweet spot of f8-11 in any case. On a bright summer's da...

Like Jon says it can be just a filter like any other lens filter but you can also convert your camera by a specialize shop, they will place a permanent IR filter infront of the sensor instead of the lens so that you can see something through the viewfinder :) Here is a non typical IR photo of min...

Flossie are you sure it's a circular polariser and not a linear one? Linear ones are know to cause small exposure errors. When you say glare up set it you should think it should actually underexpose and not overexpose like it does now. :? Yes, not linear. I think I did the testing with (...goes...

Hi! One year ago I sent one of my lenses to the Asahi Photo for a service. It is a A50mm f1.2 with filter ring damage. They told me then (after few unanswered emails) that parts for my lens is very hard to find, and that I have to be patient. So I was :) Few day ago I sent them an email, but no an...

I thought, until now, that the sensor could only record in colour. The sensor still only can records in colour because there is a fixed bayer filter in-front off it, there are sensor without such a filter and they simply record the luminance but they aren't use in standard DSLR cameras.

Hi To Stefan - I read your comments before I sent out the request. When you talk of presets, I would assume that this would alter everyone of my imported images, and still wouldn't give me what I want, e.i. the specific setting for each individual image as set by the K7. Someone mentioned an upgr...
