Inazuma Posted September 21, 2014 Share Posted September 21, 2014 4k sample of the 42.5mm here :) Looks like an enticing lens. I was only just recently looking into something of this focal length. On another note, does anyone have any advice on cleaning rubber zoom/focus barrels? I want to clean my Sigma 18-35mm up. That rubber has picked up a fair amount of dust and stuff.

Guest fe4a3f5e8381673ce80017d29a8375f1 Posted October 3, 2014 Share Posted October 3, 2014 Wide angle converters - has anyone used any half decent ones? I want to find a cheap, small alternative to my Tokina 11-16 (with mft speed booster) for my BMPCC and G6. I'm probably going to buy the Panny 14mm 2.5 as a pocketable 'normal' lens (on the BMPCC) and I'm wondering about trying a converter to make it wider. Panasonic do an official one that makes it 11mm, but it's expensive and not that radical a change in focal length. I'm happy to put up with a bit of 'character' as I'll use the Tokina for critical stuff. There are some VERY cheap ones on ebay, so I might just give one of them a punt ...

andy lee Posted October 3, 2014 Share Posted October 3, 2014 olympus x0.7 and x0.8 are good and cheap just check your lens diameter first use step ring to fit also if you have large front glass Century make some superb ones - there is a tread on this somewhere on the forum I went into detail on these a year or so ago .have a look they do work well Century ones have the best glass Matt Quote Link to comment Share on other sites More sharing options...

RamblinR Posted October 9, 2014 Share Posted October 9, 2014 Hey Andy Are MC Rokkor lenses generally good lenses or meh for sharpness wide open. Thanks Quote Link to comment Share on other sites More sharing options...
andy lee Posted October 9, 2014 Share Posted October 9, 2014 Minolta make very good lenses they are overlooked by many as they will not fit on Canon EF mounts as the flange focal distance is too short - so they go cheap on ebay for that reason . They make some very nice lenses the 45mm F2 is great and the 25-35mm f3.5 zoom is superb and cheap too as is the 35-70mm f3.5 that pairs very nicely with it - both constant apperture lenses ! they work great on micro 4/3 and sony nex cameras with adapters They also make great medium format lenses too Quote Link to comment Share on other sites More sharing options...
maxotics Posted October 13, 2014 Share Posted October 13, 2014 Hi Matt, at the bottom of this album you can find shots I took with the Vivatar 7mm (Nikon mount) on a BMPCC https://www.flickr.com/photos/maxotics/sets/72157641966461713/ My kids and I love that little 14mm 2.5 Panny lens on MFT. A little workhorse. Quote Link to comment Share on other sites More sharing options...
QuickHitRecord Posted October 15, 2014 Share Posted October 15, 2014 I've stumbled across something that might be interesting to Full Frame and S35 shooters in particular: the Sigma 24-135 f/2.8-4.5. It's a relatively modern lens (from around 2000) so it will have the benefit of modern coatings. Optically, it seems to be well-regarded, though the lens construction is not supposed to be anything to write home about. What's interesting about it to me is that the front filter does not rotate while zooming or focusing, AND it has a manual aperture (if you get the Nikon or Pentax mount versions) -- this is really unusual. The Pentax version allegedly focuses in the Canon direction too. Declicked and treated as a constant f/4.5, this could be a decent poor man's cine zoom. andy lee 1 Quote Link to comment Share on other sites More sharing options...

QuickHitRecord Posted October 16, 2014 Share Posted October 16, 2014 nice find will have to get one to try out , how sharp is it? It should be getting in tomorrow. I'll let you know. I have high hopes!

I would like to buy Canon lens, also cheap. I have 35-135 and 70-210 f3.5-4.5, both are very sharp, each cost about $80. And most important, the front lens/filter thread will not rotate.

I have it in hand (very cheap and plasticky build quality) and I'm debating whether or not to do the K-mount to EF surgery. It doesn't look like the motion of the aperture would be hindered. I'd simply be shortening the protruding lever (I would love to find a way to do this without cutting it). As is, it is already very responsive to the aperture ring. Can you elaborate on what you mean about the max aperture? The alternative to the "surgery" would be to hunt down a Pentax camera to demo the lens. Unless I am mistaken, the Canon 35-135 has an internal aperture control only, and extends significantly when zoomed which means that you can't really use it with a follow focus.

andy lee Posted October 16, 2014 Share Posted October 16, 2014 so how much does the sigma extend when you zoom it? or is it internal focus and internal zoom - if so Im getting one!! Quote Link to comment Share on other sites More sharing options...
QuickHitRecord Posted October 16, 2014 Share Posted October 16, 2014 It extends quite a bit. 60mm or so. But the focus and zoom rings do not move, so gearing them is possible. Quote Link to comment Share on other sites More sharing options...
andy lee Posted October 16, 2014 Share Posted October 16, 2014 Sounds very usable , I have a Canon 24-105 on a speedbooster thats very good it makes it a constant f2.8, this sigma goes that bit futher to 135mm which is very useful to have especially for face shots with extreeme bokeh separation from backgrounds the big plus is the manual apperture! I think Im gonna get one - thanks for the tip off! Quote Link to comment Share on other sites More sharing options...
QuickHitRecord Posted October 16, 2014 Share Posted October 16, 2014 That was my thinking as well. 24-135mm on full frame translates to an S35 focal range equivalent of 16-90mm, which is pretty close to that Fujinon Cabrio that everyone wishes they had. There's also a cheaper (and more abundant) Sigma 28-135mm f/3.8-5.6 that is supposed to have a non-rotating filter thread, a non-shifting focus ring, and a manual aperture if you get the Pentax or Nikon mounts, but I don't have that one. andy lee 1 Quote Link to comment Share on other sites More sharing options...

I just ordered an ultra slim one, but not arrive yet. I think size matters. OM lenses have good reputation. Quote Link to comment Share on other sites More sharing options...
