New zoom or several elderly primes?
No, I didn't use those sub 100 films. I see your point about the resolution comparisons (although no doubt a debate on the comparative 'resolution' of film stocks and modern sensors would run for a few pages (! :(). But is it not the case that we were less likely to be aware of the lens IQ defects, ...

According to Ricoh Imaging France
The speed of a focal plane shutter remains the same once the point is reached where the shutter speed is controlled by the width of the slit that crosses the sensor plane. I was anticipating that a faster running shutter might not last as long, but then the difference of 1/3 stop isn't going to b...

Thanks John. If I've picked to correct "Commodity Code" for a filter it looks like I'm OK

Circular Polarising Filter CPL
The following information was not immediately obvious to me so I will share my personal revelation for other newbies. I have been asked to shoot a friends Wedding (as you do) which is set for January. My immediate thought was a white dress in snow! Having already considered a CPL to increase ...

Circular Polarising Filter CPL
Polarisers also work best with the sun to the side, rather than in front or behind you. I play with the filter until I get the desired affect. You do know there is a little slide out bit on the lens hood to enable you to adjust the filter with the hood on. The hole goes at the bottom of course...

Thank you Gwyn. I wondered what that was for. Obvious now you mention it :shock:

Circular Polarising Filter CPL
They always have an index on the ring which should be turned towards the light source, it's usually mentioned in the instruction leaflet. I'd forget all about using it in a January wedding.

Circular Polarising Filter CPL
Thanks for responding Ken but there is nothing on the filter apart from the ID Lettering (HOYA PL-CIR 62mm). There's no instructions with or on the packaging. My other reason for posting, as I have, is that either TTL or LiveView I can see very little discerbable effect but it has had the desire...

Polarising Filter - Screw or Cokin?
Wishing to buy a new polarising filter. Can't make up my mind whether to get a screw on type or Cokin. I already have a Cokin 'P' system of graduated and ND filters plus holders and full set of adaptors rings for 49mm to 82mm lens threads. I would guess the polariser would mainly be used on my...

Polarising Filter - Screw or Cokin?
Its sounds like you already know this .. :D obviously the Cokin system type Polariser will prove far more flexible - the system allows the one (circular) filter to be used with all of your lenses. When I used one I didn't find it any problem to keep the filter holder with polariser attached to th...

Polarising Filter - Screw or Cokin?
I have always felt the problem with Cokin style filters is that they are very vulnerable to reflections. OK, we can use their lens hood, but what a cumbersome outfit it makes. A screw-in circular polariser can be used quite successfully even with original Pentax hoods, just remove the small windo...

Polarising Filter - Screw or Cokin?
Plus, I suppose if I bought a 72mm screw-on filter I could use step-up rings to attach it to the 55-300 and macro lens for the odd time I may need to. Guess I'm starting to answer my own question..!! Thank you. A screw on one should prove more convenient and usable with the original lens hoods...

Polarising Filter - Screw or Cokin?
I prefer screw in filters for the reasons stated above. Be aware that using a polarising filter on the DA 55-300 can be troublesome. It is never a speed demon, but I have found it hunts a lot with a filter attached, no doubt the quite F5.8 max aperture at the long end does not help. Regards - Ste...

Polarising Filter - Screw or Cokin?
Thanks everyone. With regard to the small removable window on Pentax hoods, it's a shame Sigma never thought of that!

Polarising Filter - Screw or Cokin?
[quote:3496ace15f="dangie"] .... I would think the Cokin polarizer would be far more cumbersome when it comes to rotating it. I've used their NDs but not polorizers for that reason. John K I never found it cumbersome - the polariser has a slatted rim which allows easy movement with the fingers fr...

Polarising Filter - Screw or Cokin?
Guess it's what you get used to. With my film cameras I managed perfectly well with just a 49mm thread one on my M lenses. Never needed anything else! John K

Polariser choice for the DA 12-24 f/4
Hello everyone, I am not sure should i put this in here, or the lens chat. anyway, I finally got myself a DA 12-24 f/4 lens for the upcoming field trip. however, i am not sure what type of polariser should i pick up. my main concern is vignetting, so i guess my question is should i purchase...

Polariser choice for the DA 12-24 f/4
To be honest, neither. I'd aim for a higher quality filter than the cheapest Hoyas and yes I would go for a slim filter. The Lenstip website has a good comparative test of polarisers. Balancing quality with cost, I'd recommend Marumi DHG, but they are closer to £50 in 77mm.

Polariser choice for the DA 12-24 f/4
I use a Hoya Pro1 polariser with my 12-24. I cannot notice any loss of IQ with this filter, it is ultra thin so does not vignette and has a high quality coating. In 77mm size these filters are not cheap, but you get what you pay for and if you search on ebay you may find a brand new one for around...
