Reverse adapter, macro tubes
Michal, Your Zenit lens probably takes a 49mm filter? If so you can look for a 49mm screw to Pentax K adapter ring and reverse mount the Zenit right to your DSLR. If you really want to play Macro, mount your 16-45 in the DSLR as per normal and buy a ??mm to 49mm reversing ring to mount the two...

Filters from eBay?
I consider buying a CPL filter (so I can take a picture through a window) and potentially a graduated neutral filter. I found a huge difference in prices though. I thought about Hoya filters (B+W are rather too expensive for me), 67mm (so they fit DA 16-45mm lens). Then in few internet shops I sa...

Weather sealed lenses
The simple way to protect camera and lens is to let the lens peep out of a hole in a plastic bag. Camera and your hands are inside the bag. The bag is kept in place on the lens by trapping it around a filter. Another way is for an assistant to hold an umbrella over you and the camera.

Vigneting Hoya PRO1 Circ. PL on SMC DA 18-55 3,5-5,6 AL
Stephan, Welcome to the forum - I like the shot in your portfolio very much. Personally I haven't had any problems with vignetting at wide angle settings with my 18-55. Are we talking vignetting or uneven polarizing? It is virtually impossible to get even coverage over the whole image with wide ...

Vigneting Hoya PRO1 Circ. PL on SMC DA 18-55 3,5-5,6 AL
Oh, we are talking Digital camera? Right? The lens itself at anything under 24mm vignettes like crazy. Worse with any filter. Mac... do you mean like this? :( No polarizer on this one :!: Cheers, Kris.

Opinion wanted on wide-angle lens converters
Are you talking about the kind that screws into the filter thread of the lens? Or os there a sort that goes behind the lens? Back in the late 80s when I worked in an optics development lab, our 'lunchtime' project over several years was to make a front-mounted supplementary lens. We ended up maki...

Wide angles and filters
I use the 85mm Hitech filter system currently with the plastic three filter holder. This is fine most the time until I tread into the 28mm/35mm focal length where the holder interferes with the frame and darkens the corners, far more so with the 28mm. I see Hitech do a wide angle holder and have...

Wide angles and filters
You're not by chance putting the filter holder on with a Skylight or UV filter already inplace are you? Something I've done with Polarisers far more often than I'd like to admit (usually with a zoom :oops:) - what you have discribed sounds like vignetting. Most filter systems are OK to 28mm in...

tamron 70-300mm or sigma apo version or pentax 55-300mm
Scott, I've used all three in varying degrees. Used the Sigma on a Nikon D50, Tamron on a Sony A100 and the Pentax I have only just got so can't comment on it's performance yet. But my initial feelings on these are as follows: Tamron - Pretty similar in many ways to Sigma except cheaper to...

DA 12-24 f4 Filter Use
Hi all, Been trying out my Pentax 12-24, but am finding that my Cokin P filters, even with a wide angle 1 filter holder still shows the edges of the filter in the picture unless you zoom higher than about 14-15mm. What do you do? Have you invested in larger filters? These are expensive thou...

DA 12-24 f4 Filter Use
I have hacked the front slots off a P filter and filed out the inside rim of the holder... and it's not too bad. But then I bought the Lee Foundation kit and Cokin Z-Pro ND grads :P Speedgraphic had deals on three ND grads which made it within reach - but it's still expensive :shock: Matt

DA 12-24 f4 Filter Use
I use the Cokin P wide angle holder on my 12-24 and find it's only barely noticeable at 12mm and disappears after 13. But then I don't use *any* UV filter on the front so maybe you need to use one or the other but not both? :?

pentax 100 2.8 smc dfa VS sigma 105 2.8
From an image quality point of view I don't think there's anything to choose (from what I've seen of the Sigma) between them. The Pentax though is smaller and lighter (barely bigger or heavier than the 18-55 kit with a 49mm filter size) and has quick-shift, so it's more likely to be a permanent ...

Pentax K 135mm f2.5 on eBay
The lens arrived this morning, and extremely well packed. It appears in very good condition, a little dust inside but that is neither here nor there. Luckily, I found I had a spare genuine Pentax skylight filter of the right size too. It is a fairly chunky piece of glass, and isn't dwarfed by the ...

Filters for Sigma 17-70
Hi, The Sigma is a wonderful piece of glass. Using a step-up ring should be possible. The problem(if any) about vignetting is simply find out by trial and error. The use of 2 cpl filters doesn't give you a variable ND substitute, I think Each filters takes 2 stops of light, so putting two to...

Filters for Sigma 17-70
don't know about the sigma lens but two CPL wouldn't work. They both cut away a wave length and if they are 90 degrees to each other they wont let any light through even and it's cheaper to buy an ND filter to be honest.
