Canon Unveils the EOS M2 with Twice the Focusing Speed, May Not Come to the US

eosm2_11

Canon’s first mirrorless camera, the EOS M, received mixed reviews when it first hit the market, mainly because of its slow autofocus. Canon is hoping to address those concerns with the newly-announced EOS M2, but it looks like this one might not even make it to the US or Europe. Read more…

New Tech Totally Eliminates Zoom and AF Noise from Video Soundtracks on the Fly

DSLRs and Compact System Cameras are becoming increasingly capable video capture devices in addition to being solid still shooters. But when it comes time to focus or zoom using the lens’ or camera’s built-in motor, you’re often left with glaringly obvious noise on your soundtrack.

So far manufacturers have tackled this problem by introducing silent focusing motor lenses, but one group of engineers is taking a firmware-based approach that seems to work just as well (if not better) and might someday soon do away with zoom and AF noise entirely. Read more…

Video: Comparing Canon’s USM and STM Lenses Using the 70D’s Dual Pixel AF

As Canon has begun focusing more adamantly on making its DSLRs capable video capture machines, the company has had to adjust its glass to match. The new Dual Pixel AF on the 70D is a great improvement (check out these videos if you doubt that) but if you’re planning on shooting video using the autofocus, you’ll probably get to the point where you have to choose between buying a USM lens and an STM lens.

When that time comes, the video above by YouTube user marconilanna should make that choice a little easier by showing you the differences — in both noise and speed — between one of Canon’s STM lenses and a few older USMs. Read more…

Video Clips Highlight the Tracking Speed of the Canon 70D’s Dual Pixel AF

Canon made a bit of a splash when it released the 70D, touting lightning fast live view and movie mode auto focus that would put the previous system to shame. The tech is called “Dual Pixel,” and now we have a few clips that show you just how fast the system works while filming in movie mode. Read more…

Check Out the Canon 70D’s Dual Pixel AF Technology In Action

At the beginning of the week, Canon introduced the latest and greatest addition to its APS-C lineup of DSLRs when it debuted the Canon EOS 70D. In addition to the standard specs you would expect to find in any of Canon’s APS-C cameras (the company has gotten some grief lately regarding its lack of innovation) the 70D packed one very impressive improvement.

The 20.2-megapixel Canon-designed sensor inside features something called “Dual Pixel CMOS AF”: a new autofocus system that promises to vastly improve the speed of Canon’s live view and video AF capabilities. And now, we get to see it in action. Read more…

The Magic of Firmware: Canon EOS M AF Speed Boost Seen in Videos

canonspeedboost

Earlier this month, Canon announced that there’s a firmware update for the Canon EOS M on the way that will boost the mirrorless camera’s sluggish autofocusing speeds by up to 2.3x. Given that AF slowness is one of the biggest gripes EOS M owners have with the camera, the news was likely music to many a EO M owner’s ear.

If you want to see what this 2.3x looks like in real life, Korean photographer Daero Lee has published a number of comparison videos showing updated and non-updated EOS Ms focusing on things.

Sluggish Canon EOS M Autofocus Will Be Up to 2.3x Faster with Firmware Update

warpdrive

There was a great deal of excitement when Canon entered the mirrorless camera market with the EOS M last year, but much of the buzz evaporated when people began putting the camera through its paces. Although the camera features impressive image quality, one of the biggest issues is the sluggish autofocus that often gets in the way of capturing “decisive moments.”

If you’re the not-so-proud owner of a EOS M who constantly grumbles about the AF, here’s some news that’ll be music to your ears: your camera is set to receive a major AF speed boost by way of a firmware update.

GhettoCAL: A DIY Lens Calibration Tool for Microadjustment-Enabled DSLRs

ghettocal

It’s fairly well known that not all lenses are created equal. Put that in combination with manufacturing variables and lenses don’t always perfectly align with the camera mount. Generally the differences are minor and for the most part negligible, but I buy old Minolta lenses from eBay and I want to get the best bang for buck out of them.

I started making micro adjustments to my lens/camera combinations when I first got Sony’s a77, and have now micro adjusted all my lenses for the a99 and D3. After reading what the Internet had to offer regarding “micro adjustment” or the “fine tune” functions higher level DSLRs offer, I quickly printed off some charts similar to rulers and taped them to my wall to start making adjustments.

Fujifilm F900EXR Compact Claims Crown for World’s Fastest Autofocus

fujifilmexr900a

Fujifilm launched a number of new compact cameras this week. While most of them offer rather pedestrian improvements on older models, one of the models comes with a rather eye-catching claim: the new FinePix F900EXR is said to feature the world’s fastest autofocus system found in a digital camera.
