Filters for a Sigma 150-500mm F5/6.3 DG OS HSM
I have since received my new Sigma 150-500mm lens from MIFSUDS http://www.mifsuds.com/ (excellent value and service I found). Thanks to all for their advice and encouragement. My next question is - which filter (if any) to use. I understand that a UV filter is designed for film cameras and serves...

Filters for a Sigma 150-500mm F5/6.3 DG OS HSM
Hi As a general rule with filters - cheap = rubbish. IF you intend buying a filter - be prepared to pay for a decent one. Personally - I have a CPL for every lens I own - I find them extremely useful. Having just bought the same lens as you - I am about to buy one for this lens. I like the Ken...

Filters for a Sigma 150-500mm F5/6.3 DG OS HSM
Thanks for the advice. I think I will save up for the circular polarizing filter.

Polarizing lens
Hi, just a quick question. I'm heading to glencoe today and I have a 0.45x wide angle extension lens (it was cheap but has surprisingly good results), it's attached in conjunction with a macro lens, I need to know where I should be attaching the polarising filter, on to the main lens or the attached...

Sigma 120-300mm for pentax on it's way ???
I think B&H are getting confused with this But it's still not in Pentax mount.:roll: Yes i thought that until the specs said 180mm filter thread Size 82mm , Specs for 150mm filter thread Size 72mm unless there all typo errors.

Would you swap a 12-24 for the DA15mm?
For landscape I've just thought of another advantage of the 12-24, the larger element should make better use of graduation on filters. So that's settled in my mind. As Simonkit's just set himself up with filter system for both the 12-24 and the DA15, it'll be interesting to see how he gets on in th...

Would you swap a 12-24 for the DA15mm?
the larger element should make better use of graduation on filters. When (idly) researching filter systems earlier this year, I stumbled upon the Lee RF75 system - designed for rangefinder cameras with smaller elements for just this reason. But would it work on the DA15 without vignetting, and is i...

Which is better for street photography ?
The 17-50 is about the perfect range for street and I disagree that it's a massive lens While I agree with the first part of your statement I think the second borders on lunacy! In comparison to the primes the OP listed with their 49mm filter threads the Tamron 17-50 is a HUGE piece of glass!!! ...

What is the use of a prime ?
Two hundred and fifty odd... The going rate I think. Quite a gulf in price compared to the 1.4... I got mine for £250 - It had a dint on the filter thread and no one else bid on it. Otherwise it was pristine. I've seen them go for a lot more. Don't let the next one get away :)

Holy Moly
Same optical formula as the Takumar (with 49mm filter thread) produced from 1960.

Lens for documenting / portraits at a wedding
Most MF film wedding and portrait photographers used a Zeiss Softar Soft Focus filter on their lens at all times. No other SF filter came close. It had sort of raindrops all over it.... you can see them here: I've still got at least one 67mm somewhere that was made for the Contax.

Centon 500mm Mirror Lens
Hi, I too have an old Centon 500mm Mirror and was wondering if I have to use the rear UV filter or not. Somewhere at the back of my mind tells me one had to be fitted at all times but looking on the Interweb I can find no refference to this and nothing is menotioned about in the user manual. Any ...

Centon 500mm Mirror Lens
Interesting... No idea about that, looking forward to hearing the answer. The lens produces quite washed out images by modern standards, but getting the light behind you makes a big difference. Maybe the filter would help with this.

Centon 500mm Mirror Lens
Could only find info on the Nikon 500 mirror. It`s worth putting it in a search engine to find the PDF downloades fro Mike Butkuss. The original manual states a rear filter must always be in place. I guess all mirrors are very similar, I was told that the 500 Tamron mirror that I have must also h...

Centon 500mm Mirror Lens
The original manual states a rear filter must always be in place. Yes, to stop cr*p falling in. If you examine the supplied filters you'll find that they are just flat bits of glass with no immediately observable magical properties. If anyone does find a real explanation as to why a flat piece...

Centon 500mm Mirror Lens
Thanks for all the info. Kh1234567890 got me thinking so I removed the filter from the lens. It is a KM-500 Skylight 1A and having looked at it very closely it is covered with small inperfections in the glass and no matter of cleaning will remove them. It also looks a little milky when compared to a...
