Zeiss Otus 28mm f/1.4 lens coming [CW4]

Zeiss Otus 28mm F/1.4 Lens Coming [CW4]

Sony Alpha Rumors reports that a new Zeiss Otus 28mm f/1.4 lens is coming in mid October 2015. Please note that f/1.4 is our speculation, though a very likely one. All we know so far is that it will be a massive lens. Canon and Nikon mounts are expected to be announced. There have been some suggestions around the web the lens may be a 24mm. We are pretty sure it will be a 28mm.

We had a suggestion for a new Zeiss Otus lens in September, the Zeiss Milvus line-up was announced instead. However, the rumor wasn’t entirely wrong.

Stay tuned…

Canon patent combining Phase Detect with Light-Field technology for accurate Auto-Focus

Canon Patent Combining Phase Detect With Light-Field Technology For Accurate Auto-Focus

Canon patent that appears to merge Phase Detect with Light-Field technology to improve auto-focus accuracy.

In current Canon Hybrid AF sensors, Phase Detect AF is used to quickly lock AF and Contrast Detect is employed to accurately set focus. The present patent employs Light-Field technology instead of the Contrast Detect part. That’s a cool trick, since Light-Field allows to set the focus after having shot the photo. If I get the patent right, Phase Detect is used to lock AF, and then Light-Field is used for the fine-tuning. This is not the first Canon patent referring to Light-Field technology (1 | 2). Light-Field technology is featured on Lytro cameras.

Will we see this tech on future Canon sensors? Possibly, the question is when.

Tamron SP 35mm f/1.8 Di VC and SP 45mm f/1.8 Di VC video review

Tamron’s new primes captured a lot of attention since they were announced. For a good reason. The SP 35mm f/1.8 Di VC USD and the SP 45mm f/1.8 Di VC USD are affordable, and have weather sealing and image stabilisation. That’s a lot of bang for $599.

In the video above, photographer Dustin Abbott takes a close look at the build quality of the new Tamron primes, the SP 35mm f/1.8 Di VC USD and the SP 45mm f/1.8 Di VC USD, and compares the them with their main competitors. Dustin Abbott posted also an image gallery on his blog.

In the video below, he is examining Tamron’s claims about the lenses’ performance. Do the lenses stand up in real world shooting? Resolution, image stabilization, flare resistance, close focus performance, chromatic aberration control, and autofocus are tested.
