Filter removal
John I just noticed that there was a little bit of dust present. I think that because it is cross threaded it makes it a lot more difficult. Most of the removal techniques are beyond my ability(due to disability)but will try what I can. Thanks for advice.:D Regards Chris

Soften up some Blu-Tak by leaving it stuck to the side of a kettle that's recently boiled or hold near to a fire/radiator. Roll it into lengths about 5mm diam. Stick it on the edge of the filter rim, so the rim is fully covered. Place lens perpedicular to a Formica topped or glass table....

Also found that placing an ice cube on the filter for a few minutes helps. Presumeably by shrinking the aluminium frame a smidge. Then use Blu-tak/rubber mat as above regards Bernard

I used my wifes flip flop ... pushed the front of the lens into the rubber and twisted. Was suprised how easily it came off, thought it was going to be on there forever.

I used my wifes flip flop ... pushed the front of the lens into the rubber and twisted. Was suprised how easily it came off, thought it was going to be on there forever. Oh yeah, I forgot that one. USB extension leads wrapped around the filer are another one that worked for me (cheap lenses on ebaay...

Dont know if this would work on stuck filters, but this is my so far guarantee on carbon fibre fishing poles or rods, Use double sided carpet tape close to the stuck joints both sides. This gives loads of grip for next to no pressure. Patty

My wife has some "no-slip table mats" used to keep her plate from moving on the table. Those are usually sold at places where they have supply for handicap people. I use those to remove stuck filters. I put the mat on the table, put the lens face down on the mat, then, exerting some downward pres...

That reminds me these non-slip car mats really do get a strong grip on anything you put on them

looking for photos taken at 10mm and 17mm please
Doesn't the lee wide angle hood with 150mm filter let you take @8mm?

Macro: Extension tubes/bellows/closeup lens
To answer the other points: Magnification for a simple lens system is total extension divided by focal length. (Total extension is the added extension from tubes/bellows + the focusing extension of the lens itself) The more extension you add the more magnification you get. It makes no difference ...

Stiff CPL filter
I bought a couple of cheap CPL filters to play with until I can justify getting expensive ones, (The Financial Controller says never!) They seem very very stiff to turn so have not had them on a lens yet as I think they will either unscrew from the lens or "weld" themselves while being adjusted. An...

Stiff CPL filter
I have had similar problems with cheep filters. They just do not take as much care in manufacturing as the better firms like Hoya and B&W. I would not recommend WD40 as it seems to have a negative lubricating effect and you don't want it anywhere near the front element of a lens.In the long run, its...

Stiff CPL filter
Try a soft (6B) pencil lead scribbled across the threads. Graphite is used by locksmiths for lubrication as it does not attract dust and does not flow. It the threads are too big (I assume it's the male thread) it could be due to thick anodising in which case it could be gently scraped back a bit...

Disregard the above, I didn't immediately realise that a CPL has a rotating part. Bernard

Disregard the above, I didn't immediately realise that a CPL has a rotating part. Bernard Thanks for looking anyway. I think I'll just have to keep turning it until I "break it in" or break it :) Regards

Pentax 17-70 v Sigma 17-70
I am looking at getting an improved "standard" zoom to replace my much loved but battered 16-45mm zoom. Now I would love the DA* 16-50 F2.8, but the current cost means it is out of reach. So, the options are either the Pentax 17-70mm F4 or the Sigma 17-70mm F2.8-F4 (now before you start John, I li...

Dismantling an smc Pentax-M 75-150mm f4
I've got one of these, similarly afflicted, but haven't got around to cleaning it up yet. My first stop would be to try to unscrew the trim around the front element (I've used a rubber sink plug or an M42 rear lens cap with strategically placed bits of double sided tape around the trim ring you'...

Lens Receommendations svp - wide angle zooms
The 16-45 has proven to be a very tidy lens, well pleased with it except for two things: - 16 isn't quite wide enough for some landscapes; - The missus has pretty much claimed it for her K30 meaning I'm generally using the Sigma 28-70 EX anyway! I was tempted by the Sigma 10-20, but went the wh...

Lens Receommendations svp - wide angle zooms
I recently bought a used Sigma 8-16 and I am impressed by its optical qualities. I have not yet tried using a filter on it. It is apparently possible if you do not mind a bit of DIY .

Ooh, tempting! I think my efforts at a home-made filter mount would be a little more Heath Robinson, but may give it a try! Cheers Archie
