No doubt you may be already aware but just in case you are not onto it, the 1.33x rear anamorphic adapter behaves optically like the expander and the lens field-of-view is slightly narrowed. It also loses a little light. This is unlike a 1.33x front anamorphic adapter which acts a little like a...

BM's Grant Petty is not getting any younger. A corporate amoeba may well be waiting in the wings to assimilate BM. The free lunch which has been DaVinci Resolve may well disappear into another entity or be Adobe'd into a subscription business model.

For what it may be worth or fated to be a rabbit hole, I have found green pool table felt handy for covering old CRT screens which are curved. Spray-on contact adhesive with mist coats, not heavy coverage on the glass and on the felt seems to be about the best for attaching the cloth. You need...

If you have an idle moment, this is what the image produced by a lens behind a front-anamorphic adaptor and a rear-anamorphic adaptor behind the lens looks like if a distressed cinemascope 2x look is your thing. The things one does when the means are scarce. For the more moneyed players, an...

A friend and colleague who once had a complete set of lenses for a 35BL which he sold some 25 years ago had two Cooke lenses which did not go with the camera as they are ARRI standard mount and difficult to operate. They ay be candidates for a TLS or P+S Technik assessment for rehousing but the...

I have a ruined Angenieux 16-44 16mm zoom which had been "repaired" by a tech in S E Asia with UV cure optical cement in a humid environment. There were also loose elements inside. The original metal cylinder around a group had been cut away, some edges chipped and the group crudely reinstalled...

Recently I remade the barrel of a Laowa rear anamorphic adaptor to accept Nikon F-Mount stills lenses which I have been using via a EF-Mount adaptor ring. Whilst I had the lathe set up for fabricating a tractor part and a suitable short piece of metal stock was available, I decided to remake an...

Posted per favore for a fellow filmie who is up against a bit of urgency. -------- Hey guys, needing advice on a laptop, I'm looking to make a full length 4k doco on lifestyle in a few years mostly on my Hero9 and M2Pro Drone. (I have a lot to learn still, but I have a vision. Would this...

If a reputable optical filter company was to offer user installable/removable in-dwelling behind-the-lens filters would you want to buy? A complete kit would comprise :- Individual filters mounted or clip-in inserts in choices of Clear, ND and IRND of various densities. LC1/8., LC1/4...

QUOTE: "I think my RED fits in nicely with my other shooting utensils." You Americans really get to play with the best toys. Here in Oz, cameras and handthrown rocks is about as good as it gets for the humble cit who does not live on a broadacre farm or station (ranch). Even this thing will...

Some years back, I bought a used SD301. It turned out to have had a splash of seawater onto the display face it some tie in its life and some had crept into to its gizzards. There developed some really bad crackling self-noise after several months. The value and the possible cost of shipping and...

Except for the 9mm member of this lens family made by Kowa for Cinema Products, the lenses cover a Super16mm film camera frame. The 9mm will vignette the corners. There was a modification for the 9mm, which opened the corners just enough for a clear Super16mm view. On some digital cinema cameras...

When re-assembling SIGMA zooms, is there a special thin-walled tubular tool for jigging the lens groups in place inside their sleeves and the pillar inserts being inserted through the tube? I am making very slow progress putting the pillars back in with tweezers and a tiny screwdriver as a...

I have a Sigma 50m-500 f4-f6.3 zoom. Over the years the image has become a bit spotty. The nature of the design is that in dusty conditions encountered when chasing aeroplanes in ground-to-air shots, it is inevitable that the lens will hoover up dust as the zoom extension goes in and out. This...

Just a little hint for folk to do their own fixit if you happen to have a camera with a focal reducer fitted in the throat. My arrangement has a Caldwell (speedbooster) in the throat of a "big" URSA. If you dismantle for a clean, be aware that the Caldwell optical cell can be refitted back to...
