With 1000 pounds to spend on lenses for the K10D I'd buy something like: Pentax DA 16-45 F4 Sigma 10-20mm F4.5-5.6 Sigma 70-300 APO Macro Sigma 105mm macro Totting all them up at warehouseexpress.com came to £1020. That would give you a comprehensive system plus you could sell the 18-55 an...

Pentax SMC 400mm f5.6
I used to have the Vivitar 400/5.6 which was a similar size and it was a monster. It came out shortly before the more compact 72mm filter versions from Tokina, Sigma and Tamron. Whilst it gave impressive results, it just never got used that much because of it's bulk. Kim

Pentax SMC 400mm f5.6
I was scratching my head when i read that. I would'nt have thought the filter thread would stand up to that kind of punishment. :lol: So what did you think of the vivitar lens do you recommend it. I want a long prime but i don't want to pay a lot of money for it as i won't get that much use o...

Testing old Takumars
Hi Guys, My LBA of old glass has resulted in three 1:3.5/28 lenses. They are all m42, one is the 49mm filter and the other two are the yummy looking 58mm. I want to keep one :) How can I set up some test to decide which ? I presume a tripod and same settings is a given. What sort of image s...

What lenses should Pentax make?
The 300 F4 is on the roadmap. :wink: I didn't say all the list was exotic but some of them are somewhat more unusual. I don't think the 85/1.4 is that likely. For a start it is too close to the 77/1.8. I also don't think we will see the very long lenses. I am not sure how many 1000/8 they sold fo...

Wide angle options ?
I can use my Cokin (actually a Kood) P-size set above 12mm without vignetting, but below that will show the holder. You could always modify the holder by cutting off the front couple of filter slots and that would probably avoid the problem. If you have a scew in polariser I don't see it being a...

Wide angle options ?
I have a cut-down P-holder (will hold 1 polariser or 1 filter) - no real problems on the Pentax 12-24. The polariser is the only reason I keep the P system (I can't afford or justify a 105mm circ pol for the Lee kit :shock:) A friend of mine has the Canon fit Sigma 10-20mm and has found that the ...

Wide angle options ?
When I use the P filter holder on my Sigma, I don't use an adaptor ring, the holder sits quite nicely in the bayonet mount for the lens hood instead. So the holder sits a bit further back than it would on an adaptor ring, which may well help matters. I'll have to try cutting off the front sections...

Copied from Cokin Website : ---------------------------------------------------------------------------- P Wide-Angle Holder (BPW-700) P299: This extra slim holder helps to eliminate vignetting down to 20mm focal length. Can hold 1 filter (can be a polarizer) and allows the use of filters with s...

Lens sought : equivalent of my SMC-M 20mm/f4 for ist*D....
The ist D* is a lovely camera, & digital cameras are convenient, quick (and save scanning in all those damned slides) etc... BUT I miss my Pentax SMC-M 20mm f4 ultra wide angle rectilinear lens... So I'm looking for an *affordable* something equivalent for the istD*. Focal length around 14...

Pentax 18-250 or Tamron 18-250
browngo1. I have the Tamron, very happy with it. The Tamron made Pentax is supposed to have their extra coating on the glass ? This is a keeper for me, so not a bit worried about re-sale value, in any event I don't think there would be much difference. The bottom line for me was price ...

Sun Lens 39-90mm f3.5 Macro
The Cross filter i probably a Cross-hatch filter which used to be used to give the 'twinkle' to point sources of light. Christmas trees looked good with this one... It's kinda obsolete now as it can be added easily in post-processing... I still use it on my film camera occasionally... But John...

Building your own set of lenses in Pentax World
I'm always interested to hear what other folks use as their personal kit as no two people seem to be the same. I own six lenses with my K10D, three of which are languishing lonely and unloved in a drawer; a Pentax DA18-55, a Tamron 70-300 and a Pentax M50/1.4. I'll probably keep all three as the...

Can anyone provide a list of basic filter types and their applications for future reference? What are the merits or otherwise of buying filters for lens protection? Are filters marketed for digital cameras any different from ones for film cameras, and if so how?

Hi If you do a google search you will find plenty of sites which explain what filters do what. Lens protection.......... I reckon if you do a poll you will get a pretty balanced result. I personally dont use filters for lens protection. If I was taking an expensive lens onto a windy stormy be...

I have done a search on Google and I only seem to find retailers telling me why such and such filter will help me (in other words they are trying to sell me something). What I would like to find is an unbiased objective breakdown of types of filters and how they can affect the image, or why they ...

A book on photography will explain in detail, but in summary filters are used with black and white film to correct and/or enhance particular colours and with colour film to change the colour balance. Virtually all of this becomes redundant with digital as it can all be done to the colour file in Pho...

Aren't they a bit like insurance,you hope younever have to claim, and you don't like paying for it , but you sure are grateful when something does go wrong. I must say I have only damaged one filter in 30 years, but my luck says as soon as I take them off I'll scratch a lens! So you see I've got my ...
