Have you ever wondered how those CCD sensors work? What’s behind the science that captures light and outputs all these nice pics you are shooting? We all know that having a larger sensor is usually a pretty good thing, but how exactly is a sensor working? Well, there is one thing you can take for granted: there’s a lot of sophisticated work to do. And Bill Hammack (The Engineer Guy) is here to help us understand. Enjoy the video!
ephotozine just reviewed the eagerly awaited Tamron SP 24-70mm f/2.8 VC USD lens. It’s an interesting lens: it covers a popular zoom range and has a constant 2.8 aperture. It weights 825g (29.1 ox) and has an 82mm filter mount. Closest focusing distance is 0.38m (15.0 in). Having a price tag of $1,299 it’s cheaper than Canon’s equivalent EF 24-70mm f/2.8L USM, which sells at $1,599 and does not have image stabilization (called vibration compensation in the Tamron galaxy). Build quality is rather good: High quality plastics have been used for much of the lens barrel’s construction and the wide rubberised zoom ring is well enough damped to prevent lens creep. Generally speaking, the performance of this lens is very good. Some excerpts from the review:
Just a quick post to point you to the work of my friend Mike Kobal. These are summer fashion shots done using a EOS 5D Mark III with the kit lens. If you want to see more pics taken with a 5D Mark III (and uploaded to Flickr) have a look here.
The rumors I reported about in the last weeks are getting more consistent. A few days ago CanonWatch broke the news about a possible announcement at the end of May or beginning of June of a mirrorless system camera. Now more information about such an announcement seem to have leaked. What can we expect Canon to announce in June? The Rebel T4i/EOS 650D and a mirrorless system camera. Both were expected for Photokina in September. Now it looks like they are around the corner. In September we will probably see a new EOS 7D and a second mirrorless camera. Stay tuned!
Update: these are the rumored specs of the next EOS 7D:
Advanced AF system like the 5D Mark III
3.2 inch OLED screen
Wireless flash control E-TTL III
For the time being, the PowerShot G1 X is Canon’s only attempt to jump on the mirrorless bandwagon. It’s a wonderful camera with an outstanding lens, but it’s a fixed lens. And that’s not what most of us were expecting. So, let’s wait what will happen in June!
