Website looks very nice. I look forward to racking up some rewards! Thanks very much! "April will be a big month for a new product!" We can only hope... Fingers crossed.... Can I make a suggestion Chris ... the 645 lenses either need their own section or grouping together at the end. Just l...

I saw the filter, I just think 99% of people will click on Pentax lenses and see everything jumbled up. Just looks a bit messy to me.

Thanks for the feedback Steve - appreciate it. 1. I agree and will get it changed - your suggestion would be better. 2. I see what you mean - I'll see if I can get it to look more obvious. 3. This is now sorted - we don't have any Irix lenses in stock at the moment. 4. This is a niggle f...

Jammed SW150 filter
I haven’t used this Lee Filters set-up much recently so have kept the mount off the 15-30 f2.8 lens it is designed for, instead keeping it in a rear pocket of my bag. Anyhow it must have had a bit of a knock because the threads of the parts that fit on the lens had crossed and were well and truly ja...

Ingenious method to extricate yourself from that predicament. Made me smile

Advice requested.
Food for thought. Thanks to all. To continue the thoughts, can I ask, is the practical difference between the 16mp and the 20mp sensors as big as might be thought (hoped)? It depends on what you photograph. And on what you think and hope :wink:. The number of mp's is only part of the story. Impr...

Advice requested.
To compliment Lubbymans comments as above, you prob wont notice much difference between 16mp and 20mp, you will notice the omission of an " Anti Alias filter " thou particularly in improved sharpness ( slightly ) and unless your shooting a subject with lots of horizontal lines you wont notice the mo...

Lens diameter
One for the techies...! With modern lens filter diameters getting wider and wider. I was just wondering what actual difference. If any was made ? Except more expense in filter costs, of course...!

Faster lenses will be wider as the elements need to be bigger. Full frame lenses will also need to be wider to cover the format. Then we add motors and electronics and plastics that might need to be thicker than metal. I don't think the motivations will be increased filter costs as generally len...

It's a good question and as stub points out, it isn't just a matter of speed of lens or the need to squeeze in AF motors etc. The Pentax D-FA 100mm macro takes 49mm filters. The Sigma 105mm EX macro takes 58mm filters. Both are FF, screw-drive lenses. And then there is the Irix 150mm macro. Still FF...

Lens diameter
Lenses today have more elements to better control chromatic aberration, edge sharpness, finer details and, especially for zoom lenses, distortion. Adding those elements make the lens longer. On those longer lenses for a given focal length, the entrance pupil is situated further back in relation to...

Thanks that explains it very well. I'm not very technical..lol But I do use ND filters in my studio work. Sometimes my lighting can be too strong, at their lowest setting, when I need to use lenses at the wider apertures. So I restrict the light entering the lens with an ND filter. The other day I w...

A very lucid explanation from pentaxian450, although I would qualify his comments about filters. I agree that in most circumstances a high dynamic range can be resolved in post processing but this will often require two or three exposures; just lightening shadow areas will often result in noise and ...

Is it worth getting an IR filter??? I fancy having a crack at it!

you will be using very slow shutter speeds , the R72, which is the usual one to start with , is near as dark as a 10 stop ND. Definitely worth a play though ::). Youtube is your best place to find info on using it, setting the custom white balance and if you fancy false colour how to do that plus ...
