Patent: Canon EF 180mm f/3.5 DO Macro

Patent: Canon EF 180mm f/3.5 DO Macro

This is the first I have seen this sort of patent. Canon has filed an optical formula patent for a diffractive optic macro lens. What better lens to upgrade with a DO version than the long-in-the-tooth Canon EF 180 f/3.5L Macro?

Recent Rumors

New Canon L Primes, but Not Until 2015 [CR2)

New Canon L Primes, but Not Until 2015 [CR2)

We’re told to expect new Canon L primes, but none will be announced in 2014.

The first one we can expect is a new 35L in early 2015, this has been rumored since the 24L was announced. There have been lots of patents for the optical formula, but nothing has come of it.

The second is a new 50L in late 2015. The new lens is said to be a lot smaller and lighter, perhaps a drop to f/1.4?

There may have been development delays in L lens development as Canon has been working hard building a cinema lens lineup.

Review: Zeiss 135mm f/2 APO Sonnar T*

Review: Zeiss 135mm f/2 APO Sonnar T*

Dustin Abbott, a friend of Canon Rumors has completed his review of the Zeiss 135mm f/2 APO Sonnar T* in the ZE mount for Canon. The review is pretty glowing for the Zeiss, as one would expect. Dustin directly compared it to the classic Canon EF 135 f/2L and came away with the conclusion that the Zeiss is optically better, though for twice the price it should be. However, the missing AF in the Zeiss is a big deal when comparing the two.

Says Dustin: “Will it be replacing my 135L? Probably not. Until I shot with the Zeiss I thought the performance of the 135L was fantastic, and I will still enjoying shooting with it. I knew that the Zeiss would be better before I did the review, although I was surprised by just how noticeably better it was in head to head comparison. But for many of the applications that I use the 135L in, I need the AF. But I’m also not a full time professional photographer, and frankly, there are a few higher priorities for that kind of money in my kit at the moment. I’ll keep using my trusty Canon, but I will cherish the images that I took with the Zeiss. And one day, there WILL be a Zeiss lens in my kit. They are just too good.”

High Megapixel EOS on the Way as Mentioned by Canon

High Megapixel EOS on the Way as Mentioned by Canon

The first confirmation directly from Canon about a high megapixel camera has appeared in an interview with DC Watch. The interview was about the two latest ultra wide zoom lenses, the EF-S 10-18 f/4.5-5.6 IS STM and the EF 16-35 f/4L IS and what went into designing them.

Google Translated from interview: “I to higher pixel unnecessarily is the opposite, but there is also a feeling if there is a high-performance lens that matches the number of pixels (pixel pitch), to want to take a look at the descriptive power of the true. By super-wide-angle zoom image quality is good came out to the periphery, and we look forward to the advent of high-resolution model of the EOS.”

We were told previously that there would be 3 EOS cameras in 2014, and so far we have seen just one, the Rebel T5. There was also the white Rebel SL1 (i dont count this as a new camera). The next one will be the follow-up to the EOS 7D and the third one is still a mystery. It could be something as simple as a new Rebel, or perhaps something far more interesting.

Review: Sigma 12-24mm f/4.5-5.6 DG II HSM

Review: Sigma 12-24mm f/4.5-5.6 DG II HSM

Bryan over at The Digital Picture has posted his review of the Sigma 12-24mm f/4.5-5.6 DG II HSM. This is the widest rectilinear lens available for full frame Canon DSLRs. If you’re looking for a lens that will give a truly unique look, this will definitely fit the bill.

Says The Digital Picture:
“This lens is not without some shortcomings, but what it offers is available in no other lens. The Sigma 12-24mm f/4.5-5.6 DG II HSM Lens is the widest angle rectilinear lens available in a Canon, Nikon, Sony or Sigma DSLR mount. This unique capability will allow you to capture images that would otherwise not be possible and the quality of Sigma 12-24 II images can be also-impressive.”
