Lens protection filters
this has been asked berore and i believe the consensus was why would you put a cheap uv filter on the end of an expensive lens as all it can do is damge the image quality. if you were to fall or drop your camera/lens the chances are you could smash the filter into the front optic of the lens . per...

Lens protection filters
Back in the era of the Pentax ME Super, Olympus OM10, Minolta X300, Yashica FXD and the like, skylight or UV filters were sold as protection and haze reduction for the lens but even then there was debate over possible flare and IQ degradation (this argument was usually countered by offering the more...

Lens protection filters
I agree with all that's been said.. I thought UV filters dated back to the film days. Were many lenses at that time didn't have hoods and it wasn't so easy to purchase a cheap Chinese one from the internet...!! My Pentax FA 50mm 1.4 for example....

Mach loop
Cheers for the link Derek...some really good shots there. If it gets any more popular though the local council will have to build a toilet block and someone will probably start charging for access to the hillsides! Regards Karlo That could well be true, then health and safety could kick i...

Mach loop
I've seen some fantastic images taken from the Mach loop over the years, my favourite was an inverted Jaguar (the best way to go over a ridge and continue to fly low is to invert just before you go over. Then you pull back on the stick to dive down into the next valley, inverting back to normal fli...

Your concerns regarding safety are real given the section of the motoring public who don’t recognise that a bike is another vehicle and has to be treated as such. However uou would be surprised how it is possible to utilise safe routes with little traffic and parks and deficated cycle paths can ...

I've thought about one of these, although the East of Fife can't be called hilly I always seem to rack up 1500 plus feet of elevation in 25/35mile outings - with a 7kg back pack I do get a bit tired :-) Might take one for test.

I picked up on your comment Daron about putting your bike in the back of your SUV. I always carried my lightweight pushbike on a Thule bike rack on the roof of my hatchback. By comparison I find the electric bike really a bit too heavy to comfortably and safely lift up onto the roof rack. Dropping i...

Losing weight
My landscape kit comprises a K1 and the f2.8 FF lenses 15-30mm, 24-70mm and 70-200mm, plus the Lee Filters SW150 system and assorted polarisers. And a tripod. Whilst in a backpack this lot is manageable the weight makes it not particularly enjoyable and limited to short walks. However I love using t...

This is not rambling at all Rob..!! For Pentax users it is an issue I feel.. I am in the process of setting up a Landscape kit myself. But I'm having similar issues .. Though in the really wide angle lens dept. I havint yet made the purchase. After looking at cheaper Samyang and Irix offerings.. ...

Thanks all, I am encouraged Derek by your recommendation of the Samyang 135mm. Smudge, I thought about the DA 200 and made a point last week of seeing what setting I was using most on the 70-200 and concluded it is a bit long for landscape. Stub, you are right about the 15-30mm it is a great lens bu...

Multi Exposure as an alternative to ND Filters (Discuss)
There was some sort of discussion on this a while back, but I can't seem to find it. However I have one posted in this thread - no 8 in the thread - 30shots. I agree it doesn't give the ultra smoothness of a proper ND filter, but sometimes this doesn't matter. It can save some time fiddling around g...

PEF's and exposure bracketing?
A K-5 has such a wide-dynamic range that you can underexpose and bring the visible colours back from the RAW files. I did see a webpage recently where the blogger was showing the technique. Just can't remember who it was. This nuthatch was originally just a black frame. I pulled back a few sto...

PEF's and exposure bracketing?
And someone even told me over at PentaxForums that in M camera mode with a flash on in P-TTL mode, that the EC control on the camera adjusts the flash exposure! Apparently. There's loads of little tricks and tips about our cameras now, many of which those used to much older equipment will never ...
