Outside of Simga’s new line of USB hub connectable lenses, adjusting the autofocus on a lens has never really been an easy to access process, but now it seems Canon is also looking into improving user access with a new patent. The patent first spotted by Egami (translated) suggests the camera company could add an automated AF adjust feature to Canon cameras and lenses.
According to the patent description, researchers looked into automated AF microadjustment as a way to automatically fine tune the focus of their lenses to the DSLR body. It’s not completely uncommon that a lens will be calibrated slightly off, the focusing algorithms will have errors, or simply that two specific copies of a lens and a camera don’t go along so well out of the box.
Thus far, AF microadjustment on Canon DSLRs–and not all Canon models–and AF Tune on Nikon DLSRs requires digging into the settings to do some fine-tuning on lenses. Canon’s new patent suggests an easier auto-adjusting solution to fix lenses for users without the keenest eye or technical know how. The patent does not exactly say if the automated adjustment would come as a one-button fix on its new DSLRs or any technical information on how it would actually work.
As with most patents, we won’t hold our breath for it to actually become a real thing. That said, if anything else develops out of this automated AF microadjustment patent you can be sure we’ll report on it so stay tuned.
While we never thought anyone that uses Canon’s C-series cinema cameras would want better autofocusing (you know, because they’re cinema cameras that often work with focus pullers), the company announced recently that they’re offering a Dual Pixel AF upgrade to users of the C100. The C100 is the company’s entry-level Cinema EOS cam, and Canon’s press release sounds like they’ll offer a sensor switch of some sort. It still isn’t totally clear, though.
Dual Pixel AF first debuted in the Canon 70D to drastically improve autofocusing in video. It essentially allows for phase detection to work by placing those pixels on the sensor. In the results that we’ve seen so far, we were highly impressed.
We’re also still waiting on our Canon 70D review unit.
We’ve seen loads and loads of rumors on the web along with many clear signs of evidence pointing to something really big coming. And by really big, we mean full frame. At the time of the publishing of this piece, Olympus has just announced their OMD EM1 camera with a Four Thirds sized sensor. Besides the obvious marketing push that a full frame sensor can give a company or camera system, it only seems like a matter of time until Sony wipes the floor with the rest of the industry and releases a full frame mirrorless camera. And with that said, the mirrorless interchangeable lens camera world will experience the same shift that the DSLR world took where everyone always complained about the smaller sensors in Olympus cameras.
But in many other aspects, the company could find a home with others.
A couple of days ago my friend messaged me and asked when I think all of the Sony lenses will get an update to be compatible with the new A99. I replied saying what do you mean? They are all compatible! This was the start of a discovery for me that I somehow missed during my press release with Sony, my news writing and Chris missed this with his hands on impressions with the camera.
The news is / or at least my impression at the time of launch was that the 102 AF points would work alongside the 19 point AF to ensure a more precise focus. The truth is that the 102 AF points will only work in the new AF-D mode of the camera which can sense depth and continuously track objects very accurately. The big news to me and the staff was that the camera only currently supports 6 lenses at this point of time. [click to continue…]
Well an adapter for controlling aperture has been around for awhile now which gave the NEX full electronic control. The video above demonstrates how the new adapter will work, it seems like it hunts quite a bit with the 50mm 1.8 shown. There isn’t much detail on the new adapter whether the adapter will work the same with EF and EFS but if its anything like the manual focus version it will support both. The video shows an older model NEX sensor so Im not sure if the new sensor with embedded AF points will improve hunting and performance.
The price in the manual focus one linked above is $250 so I expect the adapter when it is released in a few months will be a bit more than that. Thanks to Sony Alpha Rumors for discovering the adapter.
