  1. http://vimeo.com/74613572   My serene short macro film.   Mostly shot on Pentax-A 100mm f4 macro, with very close up shots using a reversed Sigma 24mm f2.8 super wide II.   I used my k-5 for tests and stills, but used a Canon 600d with Technicolor cinestyle installed for the actual shoot, as the dynamic range is greater, and it has manual controls. The lenses are attached using a canon-pentax adapter, which can be bought from Ebay for £10/$15.   To get closer I used a set of 50mm extension tubes, and sometimes used the Canon 600D’s 3x digital zoom (which is still full 1080p HD, a useful feature and no extra depth of field loss!)   The film itself is rather light on narrative; it’s just a progression of – hopefully!  â€“ interesting shots.   Hope you like it. I’m happy to answer questions on how I did specific shots and it’s always good to get feedback.  
  2. Very true on the depth of field - that was useful. Also, with reversed lenses the focus isn't flat across the frame so the edges have poor image quality. With 3x full HD zoom you're getting the centre of that frame with much better corner sharpness, which is very useful - although the chromatic aberrations are multiplied too, which in some shots is pretty noticeable.
  3. This is my short film 'Light' I've been making over the last month using a Canon 600d with Pentax lenses.   http://vimeo.com/69428988   It's a short (90 second) simple story about a lighthouse getting through the night, and features lots of experiments in cinematography - all done on my kitchen table with reversed and macro lenses and a lot of ice!   We used a Canon 600D (with Pentax adapter for my lenses) for the film itself as the manual control on this camera, the full HD digital zoom ability and swivel screen made it very useful for those tiny close ups! The film is all shot "live" in 25 frames per second, it's not animated.   We used a Pentax-A 50mm f1.2 and a Sigma 24mm superwide II f2.8 mounted in reverse for super-close ups, and a Pentax-A 100mm f4 macro for the widest shots - none of which had an area bigger than, say, a post-it note - and some of the extreme close ups were over an area the size of a fingernail or smaller at around 2:1 to 4:1 scale. For the reversed lenses we used a Canon to Pentax adapter, then a Pentax reversing ring (52mm filter thread for both lenses), then the lens! Note, if you want to use a lens in reverse for close ups you need to use one with an aperture ring, which means most modern digital lenses won't give you any aperture control.   We needed a lot of light for shooting down to f16 at 1/50 at ISO 160 in extreme macro where you get several more stops of light falloff, and so we had a big hot 800W light. For some shots it was around a foot (30 cm) from the ice, causing severe melting problems! So we needed to be fast and accurate with focus to a millimetre level on a disintegrating, slippery set all of which was too small to position without completely ruining composition! Most of the time it was a fun challenge but was occasionally frustrating!   The ice variety was achieved by chipping it in different ways, letting it melt for different times, freezing larger volumes of water (mug sized) and smashing the ice with a hammer to get particularly clear stuff, or ice cube size to get the cloudier stuff. Some of it had a small amount of blue food colouring too.   We edited in Premiere Pro CS6 and After Effects CS6, where we added the lighthouse light and did a little colour correction.   The film was made for the Depict short film competition in the UK. I hope you like the film, happy to explain any techniques and looking forward to hearing your thoughts.
  4. http://vimeo.com/44671010 I was camera operator for this film for a competition run by the Edinburgh International Film Festival for sci-fi shorts made in 52 hours or less (don't know why the weird time limit!) I used a Pentax-M 50mm 1.4, Pentax-M 75-150 f4 and Pentax-A 100mm macro on a Canon 7D with a $10 adapter from eBay. For the ship effect at the start, the ship was a painted model about 2cm / 3/4 inch long shot on the macro lens and green screened in front of the CG planet (made from a spherised flat map) in front of cg stars and flare- we were quite pleased with ourselves! Hope you enjoy it!
