Canon CN-E 70-200 T4.4 L IS KAS Leaks Ahead of Launch

UPDATE: Ooops, B&H posted their video about the lens too early. Canon are set to launch a new CN-E 70-200 t4.4 L IS KAS lens at NAB this week, to compliment the 18-80 t4.4 L IS KAS that was launched last year. What’s unclear at this point is whether the lens will cover a full frame sensor, or only a super-35mm sensor. The 70-200mm focal range has always been used in full frame lenses, so it would be a considerable departure from the norm if this lens was restricted to a smaller image circle. If the lens covers a...

More Patents for Canon CN-E “Super Zoom” Cinema Lenses

When Canon launched the original C300 video camera they also jumped head-on into the world of cine lenses with the CN-E 14.5-60 T2.6 and the CN-E 30-300 T2.95-3.6. These have since been followed by a variety of zoom and prime lenses, and every one of them has been met with high praise from people in the industry, with lenses like the 30-300mm becoming a staple addition to aerial filming units, and the insane 50-1000mm taking the top spot in natural history film units for people like the BBC and National Geographic. Lenses with gigantic zoom ranges are not uncommon...

Canon Patented Three More Apodization Prime Lenses – 24mm f/1.4, 35mm f/1.4 and 50mm f/2

It has previously been widely reported that Canon patented a lens design for a 135mm f/2 focal length that includes an apodization filter (APD), much like the Sony G Master 100mm f/2.8 lens that was launched just last week. In fact, Canon seems to have taken things more seriously than that and we can exclusively reveal today that they also hold patents for three additional lenses that include apodization (APD) filters: A 50mm f/2 APD, a 35mm f/1.4 APD and a 24mm f/1.4 APD. All of the lenses are EF (full frame) lenses. An apodization filter is essentially a circular graduated...

What Is an Apodization (APD) Filter in a Camera Lens?

An apodization filter is a graduated neutral density filter that sits inside the back of a lens, and helps to smooth out the transitions in out-of-focus highlights or “bokeh balls”. Whilst the effect is most obviously seen in these highlight areas, as you can see from the Sony example below, the filter also causes a general smoothing of all OOF background areas. In short, if you want awesome, creamy looking bokeh, a lens with an APD filter is the way to go. So why haven’t we seen more of these lenses then, if they produce such a generally desirable...

Nikon Granted New Patent For 24-70mm f/2.8E PF ED (Phase Fresnel)

Nikon was first granted a patent for a 24-70 f/2.8 PF lens back in September of 2014, but since then the only PF lens to come to market was the 300mm f/4E PF ED VR PF. PF Lenses feature what Nikon is calling a Phase Fresnel lens element, or Diffractive Optics as others like Canon are calling it. If you’re not familiar with the technology, you can read our knowledge base article entitled: What are Diffractive Optics? Although new developments around the technology seem to be slow, as they have been with Canon DO lenses, it’s no surprise to see...

What Are Diffractive Optics Lenses?

Lenses that contain so-called diffractive optic elements are becoming increasingly common, and judging by the huge number of patents surrounding the technology, it’s something that we can expect to see appearing in many more photographic lenses in the coming years. Canon has a few lenses in their lineup that contain diffractive optics, and these lenses are given the DO designation and feature a green ring around the lens barrel. Nikon call the technology Phase Fresnel, and give their diffractive lenses the PF designation, but despite the different naming conventions this is exactly the same kind of technology. What Are The...

Canon Patents 135mm f/2 Lens With Apodization Filter

Canon has been granted a patent for a new 135mm optical design that contains an apodization filter. The lens is an EF mount lens with an aperture of f/2. Will this lens replace the now ageing Canon 135mm f/2?  Typically, lenses with an apodization filter have been sold as excellent portrait lenses, which is certainly the strength for the 135mm f/2 lens, so it’s a distinct possibility that this will be the replacement. An APD filter is essentially a circular graduated ND filter that sits within the lens and helps to smooth out the transition of bokeh highlights, and...

New 5D Mark IV Firmware – V1.03

Canon have released firmware update V1.03 for the 5D Mark IV, you can download it HERE. Below is a list of improvements, and whilst most firmware updates typically contain seeming outlier cases, this one includes a fix for any usage with the 1.4x III and 2x III extenders. A high proportion of 5D users will probably use one of these at some point, so I’d rank this update a little higher in importance than most that I usually post about. Firmware Version 1.0.3 incorporates the following fixes and improvements: Corrects a phenomenon in which the color of images varies...

New Canon 70-200 f/2.8 L III on the Way?

The 70-200 f/2.8 L IS II is a staple lens for Canon professionals, but it seems that a replacement might soon be on its way. Canon Rumors is reporting this week that they have heard the lens has made its way onto internal timelines. Quite what this means in terms of time frames is anyone’s guess right now, but I must admit I’m surprised to see a replacement on the horizon. The current MK II lens is highly regarded, and one of Canon’s absolute sharpest zooms. CR mentions the possibility of a lighter lens construction, which makes sense, and...
