Alyssa Miller has this interesting article on the sweat spot of many lenses, and it is worth a read. Sure it was different when this was initially stated since it was large format cameras, meaning F/8 was much less depth of field than modern cameras, but still, it is a pretty much sweet spot on most lenses.
Jay Holben and Christopher Probst, ASV book the Cine Lens Manual has been released for $175. It is 836 pages and from what I hear an amazing read. I wish it was a little less expensive.
Photorumors has the press release on what sounds like a bad ass and fast lens, which as as a C lens acts like a 27-52.5mm on a 35mm and is really fast. No word on price yet, but it likely won’t be cheap!
Cinescopophilia has a great little article on the British Dog Shit Optics, which use old Russian lenses and make them for either DSLR’s or ARRI-PL mounts, and while built off of old Zeiss designs, they have no coating, so will flare like crazy! VERY VERY COOL!
They are quite reasonable too. You can buy them from their Etsy store for $155 for the DSLR version and $310 for the ARRI-PL mount.
I so want one
Saw this at filmmaker IQ. Sounds like Magic, but it adapts Canon EOS lenses to APS-C, and because it uses all the light and the whole frame it is actually added a stop of light and making it sharper. Almost magic!
Too bad they don’t have it for EOS to EOS for ES lens to APS-C instead of for SONY NEX.
You can pre-order from Metabones.
Photo Rumors has the news from CES on the new 14mm t3.1 and 135 t2.2 lenses. And around $5000 each. Still out of my price range, but very reasonable, just wish they were a little faster!
Canonrumors is reporting on a problem with the Canon EF 40mm f2.8
If pressure is applied to the lens barrel while the lens is mounted to the camera (pressure can be applied even while attaching the lens cap or while carrying the camera with the lens attached in a bag), the autofocusing function of the lens may stop working.
It seems they will have a firmware update for the camera in August to fix the problem, but for now just remove the lens and put it back on.
