Sigma 10 - 20mm F3.5 EX DC HSM - polarizing filter recommendations
Using a polariser with an ultra-wide lens can give rise to striations in blue skies, as the polarisation changes with the change in angle from the sun. These lenses also naturally vignette, so polarisers are less useful really. If you still want one, expensive ones are more neutral in colour a...

Sigma 10 - 20mm F3.5 EX DC HSM - polarizing filter recommendations
I would agree would agree with the above and also add Sigma are quite clever and are aware of the vignetting and other issues with adding filters to their wide angle lenses. They add a some sort of coating I think, which gives images an almost polarized look already, lovely blue skies, particularly ...

Ephotozine review of the 60-250mm
I am a big fan of the 60-250, used it a lot in the US last week, just can't wait to filter through the photos. Sharp as tack at 250 mm, image only let down by user imcompetence.

Limted 35mm from Ebay Japan
£195 was certainly a bargain - think I paid over £300 for mine - used but only one month old. I would not be put off by the plastic lens mount - they are very strong - have had several lenses with them and never an issue. The other comment I would make is that I find the built in lens hood a ...

Limted 35mm from Ebay Japan
The other comment I would make is that I find the built in lens hood a curse rather than a benefit. Impossible to use a filter and the hood at the same time and the lens cap will not go on if you have a filter attached. Carl Are you referring to something like a polariser, Carl? There is a HMC UV...

The need for a lens hood.
The following pictures show the difference between using a: 1.) With UV filter (high quality Hoya HMC) and no lens hood. 2.) Without filter and no lens hood. Note the slight improvement. 3.) With lens hood and no filter. Much improved. The sun came from the front left direction. With fil...

The need for a lens hood.
I always use hoods, just seems like common sense .. sure, it won't always make a difference , but it reduces one potential cause of contrast reduction. Lets not forget also the clear advantage of the physical protection offered to the front glass by hoods - on my Samyang the rather short petal hood ...

The need for a lens hood.
So it does, and of course most or all of the latest Pentax lenses do. The earlier Macro lenses did not come with a lens hood, because I suppose Pentax thought there was no need for it, because the lens elements where very far set back. However this was completely nullified when using a filter. ...

18-135 ed wr
Simon Quite a few of my recent images posted here were taken with the 55-300, including quite a few landscapes. I think that it represents GREAT value for money. However, when I brought it I immediately put a protective filter on the front of it and the results, while still good, were quite...

55-300 Trade in value?
Mine's very good - once I took the protective filter off the end! You haven't said whether or not you have a protector/UV filter on it, if you have - take it off and try again. On my example, I was pretty dissatisfied with the sharpness until I took the filter off - for then on it has been extre...

Advice - Sigma 17-50 F2.8
Thanks to you all once again for your kind assistance. Hi David Did you get hold of some raw files from the Sigma 17-50? I recently bought this lens and love it so if you would like me to send you some alternative raw files taken on a K3 then I'd be very happy to do so. If you were a li...

Pentax 55-300 HD WR lens

New lenses How Exciting!!!
I can't see it reaching 450 myself 400mm maybe, if it did, it wouldn't be very compact and pentaxy, (Word:shock:?) then would it? Ricoh does not seem to have strayed from the ethos... yet... If it were 450mm and F5.6 the filter size tops out at just over 80mm, as far as I know Pentax bodies still o...

New lenses How Exciting!!!
any news for the wide angle lens, there is a new wide angle lens in the 2014 lens map. hope they can get a wide enough lens which can be used with a filter in the same time just like Tokina 11-16mm f/2.8 PRO DX II

Lens hood for SMC 28mm f3.5
I think that lens has a 49mm filter. Pentax made a lens hood specially for the Takumar version. It fits over the lens and has a special locking ring. I used it with the 28mm M lens years ago. I've just taken a couple of pics of it: dave k

Lens hood for SMC 28mm f3.5
The SMC 28/3.5 (aka the 'K' series) and the M-series 28/3.5 have different threads and constructions. The K is an 8-7 lens with a 52mm filter thread and the M 28/3.5 is a 6-6 construction with a 49mm thread. The correct hood for the K is the PH-S52. The rubber ones work well, though, and are easi...
