Circular vs Linear Polarizing Filters
And just to add, that if you have several lenses then the Cokin A or P system may be cost effective ;) In addition, the polarisers fit snugly in the first slot, so they're better for wide angle lenses. ...now I'm just waiting to find out if I can still use the Cokin-P on the new 12-24mm which is...

Circular vs Linear Polarizing Filters
Hi Mac, Sorry to have added to the confusion :P There are four Cokin sizes: A - cover 36mm to 62mm P - cover 48mm to 82mm (filter is 84mm square) Z-Pro - cover 49mm to 96mm (filter is 100mm square) X-Pro - cover 62mm to 112mm (filters are 170mm x 130mm) You'll find plenty of "A" series fi...

Circular vs Linear Polarizing Filters
John, Thank's, based on your reply, I have the "A" series holder with the 49mm attachment. As I tend to be a fumbler, I can just imagine what I could do to acrylic filter inserts! I have a lot of good 49mm screw-in filters from Hoya, Olympus and Tiffen and a 58mm B&W UV on order for my...

Circular vs Linear Polarizing Filters
Matt, Thank you for your detailed reply. I'm always amazed at how much selection and availability you folk have in the European arena! I can see that the Conkin type of filter system could be very attractive to a professional photog - especially the P series. You could have every type, intensi...

Circular vs Linear Polarizing Filters
I'm not sure what you have when you say cutouts and frame, but I sometimes cut out shapes(hearts,stars etc) from black cardboard and tape them to my uv filter. try photographing a person with those cutouts with city/xmas lights (anything that'll make specular highlights) in the background and the c...

Circular vs Linear Polarizing Filters
Oh, one more thing, then I'll shut up for a while... stacking 2 polarizers will give you an infinately variable nd filter. great for 1-8 hour exposures to remove traffic and people from cityscapes during daytime.

Circular vs Linear Polarizing Filters
Cokin, Conkin, Colkin................ :shock: If I remember correctly, the Hoyarex system is essentially the same and there are other makes too. Mac, don't discount acrylic filters entirely, even cheaper ones can have their uses. They are lighter than glass and being flat, can fit snuggly insid...

300mm f4.5 F info required
I have the 300mm f4.5 F* ED(IF), which is an absolutely fantastic lens. It's very sharp: mine almost always has a 2x teleconvertor on the back, and there's very little loss of quality. It handles very nicely, and is pretty compact. The built-in lens hood is very handy, as is the tripod mount, which ...

Fast fifties - info please!
I've got the 12-24 and so far I've done some interiors with it. First impression is really favorable. There's practically no barrel distortion at 18mm which is impressve. You could even forget to use the lens correction filter and you'd never know the difference! The 31 is a great normal for ...

Sigma announce 10-20mm for Pentax K
I agree with you, Kevin, the important thing is to take pictures. When it comes down to it, we don't need much equipment to make great photographs, but there's always a big difference between "need" and "want". It's not so much brand loyalty that lies behind my Pentax-only choice, but the consist...

Lens damage repair question
Several years back I had the misfortune/stupidity to drop a lens from waist height out of my rucksack onto concrete. Even more unfortunate it also happened to be my favourite and most expensive lens, an FA* 85mm F1.4. The lens still operates perfectly well and is optical just as good as it always...

Lens damage repair question
Hi, Any reasonable camera tech should be able to straighten for you and I wouldn't expect hin to charge more than a few pounds. (http://www.daphotography.com/repair.html) Alternatively, do it yourself. There are special tools you can buy for such things but an easier and cheaper method is to make y...

Pentax-M 40-80 F2.8 Zoom
If use Cokin system filters the rotating from of the lens is less of a problem as it's designed so you can hold the filter in position while the lens rotates.

One for Mac
I had the Vivitar 400/5.6 (the early large one with the 77mm filter thread.) It is about the same size as the Pentax one. I found that with practice it was not too bad to handhold. Many of the shots taken in the Falklands on the website were done with this lens and on 100ASA film. It is rather diffi...

Fungus Prevention
I've found that my basement studio works fine for long term storage. We keep the humidity down with an airconditioner in the summer, we don't cool it too much, but just enough to remove the humidity. winter, that room has electric heat. We always run a hepa filter, and dust often. I need my comput...

Pentax 85mm f1.4
Thank you George, as recommended I took a cloth to the lens and camera copper contacts and a surprising amound of black oil like dirt came off. The metering has definately improved and I dont get such contrasting readings, however I have found that the camera tends to underexpose, although Im sure...

Pentax 85mm f1.4
I don't use filters on my 85mm for a couple of reasons: 1) Why stick glass of lesser quality in front of something so optically perfect? 2) A few weeks after I bought mine I dropped it out of my rucksack onto a marble floor and it's now got a big dent in the filter ring! I don't fit UV filt...

Pentax 85mm f1.4
This is one of those questions to which there is no standard answer. Like Steve, I don't use protective filters, but thankfully only for the first of his reasons. Plenty of people, however, do use such filters, and provided they are of high quality, any image degradation is likely to be pretty sma...
