About filters system
definetely helpful! The quote from Cokin regarding 19mm lenses is assuming the lens is used on a 35mm camera. At 12mm the 12-24 is about the same angle of view as a 18mm lens on film, hence a very slight vignetting at this widest point that has disappeared by 14mm. so there is a little bit of ...

About filters system
I don't use straight ND filters (I have a couple that have been thrown in with old cameras and lenses that I've bought but never felt the need for them), only graduated ones which I use for balancing the sky in landscapes. The three GNDs in the Cokin P kit plus a couple of Hoya CPLs are all I ever u...

Really thank you all and Stefan particularly. I had read again the post and you repeated me some things 2 or 3 times without losing your temperance! sorry but the subject is new and I'm learning it now! To summarize: A) I'll get the Cokin P system + grad ND kit (£40) I would be willing to spen...

:D:D very good idea! I prefer the 2nd for the reflections, the 1st for the sky, can't decide on the 3rd one, maybe the 1st.... Don't I like polarizer?! or is related to calibration? yes absolutely a screw-in filter, also for protection! especially if it has no point on 12-24, and will be u...

Well those last photos were a bit small. You should see that the colours of the bottom photos are more vibrant (more bold). let me get some bigger ones. Here is a read about filters I really like the effect the Pol gives so I'm always using it. With doing macros of flowers the colou...

About filters system
I'm posting it as a summary (please correct me if there is anything not correct!): When it comes to filters (as well as lenses) you get what you pay. I arrived to the conclusion to buy a CPL screw-in filter (possibly from B+W,Heliopan, Hoya Pro1) for the 17-70 (as it should be nearly useless f...

Max I've asked the shop. They couldn't say the price for sure since they don't know if they have increase the price the last 4 months but expect it to be 60 euro or a bit more. There comes of course P&P to england with that, they ship insured and it cost me 14 euro to ship a lens to the UK a month ...

Hi Stefan, thank you for your help. those prices are very cheap, I wrote them an email. AS Cokins looked quite expensive (£114 holder+grad nd kit +£10 adaptor), yesterday I did a research and found out that Hitech and Lee could be an alternative, slighlty more expensive, but much better quality ...

Lens extension FA50
...or (brainwave) a big hood! The front element doesn't rotate so holding onto it won't effect operation, just make sure you get a rigid one (like the one on your 18-55) and not one of the rubber ones - any with a 49mm filter thread attachment would do, it doesn't have to be specifically for Pentax....

LENS CAPS NEEDED
I believe the rear cap would be the same as for any other Pentax lens. I use a Snapcap on my 50mm 1.7. http://www.bhphotovideo.com/bnh/controller/home?O=search&A=search&Q=&ci=0&sb=ps&sq=desc&sortDrop=Relevance&ac=&bsi=&bhs=t&shs=lens+cap&at=Brand_Op%2FTech+USA&basicSubmit=Submit+Query I believ...

50mm
And the DA* has a extra 5 mm. It's a 55 mm, you know :wink: Filter size: 58mm, instead of the 49 mm of the FA 50. Martin. Edit: Stefan, I think he means the DA*. Talking about F 1,4.

Which lens/lenses would you bring on a travel abroad?
Max - I've toured Australia twice and New Zealand once, and will be back next Easter (atbe). My advice based on what I used on those trips would be to take all 3 zooms. The 12-24 will be the normal walk around lens - wide enough for street scenes in towns and cover most landscape needs but have t...

Kit Lens v 16-45, opinions please
The 16-45mm is definitely a step above the 18-55mm, but the kit lens is actually very good. For big enlargements and critical work go for the 16-45mm. For web use and smaller prints go for the more compact 18-55mm. If you need a wider angle than 18mm then the choice is also clearly in favou...

Macro experimentation pointers
Hi all, getting along very well with my GX-10, and really fancy experimenting with some macro work. The idea of reverse fitting, sticking lenses to lenses etc appeals no end to me (i'm an engineer and love this sort of 'playing' with things to get weird and wonderful results) Dont fancy playing a...

Cheap Macro: Pentax KA fit Cosina 100mm F3.5
If anyone wants a cheap macro lens, seems the seller didn't think putting the word macro in the title would increase interest so he left it out :oops: :roll: Finishes: 21-Jun-09 18:58:02 BST With 23hrs to go £10.50 Pentax KA fit Cosina 100mm F3.5. This is a manual focus macro 1:2 lens, and ...

200-300 RANGE
Hi! I'm using primarily my Pentax da 55-300. Very nice picture quality. At least mine is sometimes a bit hunty lens, but manual focus first before autofocus and that problem mostly solved. I'm using a protective Hoya Digital Pro filter, which might affect performance, haven't tried it without yet....

200-300 RANGE
Btw, do people here use a protective filter and do they find it affects performance or IQ? Some do, I don't. My feeling is that filters should only be used when necessary as adding any extra glass to the optical system can only lead to a reduction in IQ, however slight. Others feel the need to p...

200-300 RANGE
Others feel the need to protect the lens from damage, arguing that it's cheaper to replace a filter than a lens. Having said that, a smashed filter can damage the lens anyway with the broken glass shards. Thanks for the swift answer to my question. I didn't come to think of that the filter might als...

200-300 RANGE
Just take care. I use my non-WR lenses in the rain (modest rain anyway) but shield the lens and keep it as dry as possible. The same applies to dust. Otherwise, you wouldn't take it anywhere such as Egypt, which is dusty enough! In very bad conditions I might use a filter for protection from s...

Lens Prices...
Correct me if I'm wrong, please, but I was of the understanding that Pentax and Sigma both operated an import structure of Japan -> Europe (main central distribution point) -> individual European countries. Because the Yen to Euro exchange rate is lousy, there's one hit there, and then the Euro t...
