Photography Blog published their exhaustive review of the new Canon EF 24-105mm f/4L IS II lens. They found that the EF 24-105mm f/4L IS II is “much better” than the lens it replacers, the highly popular Canon EF 24-105mm f/4L IS.

In the conclusion they write:

[the EF 24-105mm f/4L IS II] offers a very versatile focal range whilst being tack-sharp from 24mm to 50mm, both in the centre and at the edges of the frame. Sharpness at 70-105mm isn’t quite as good when shooting wide-open at f/4, but overall the Canon EF 24-105mm f/4L IS II USM delivers excellent sharpness across the frame. Vignetting at wide-open apertures and some barrel distortion at 24mm are the only other real optical issues of note.

Build quality is excellent, certainly up to the usual L-lens standard, and Canon also provide a very good lens hood and padded case. Focusing was very quick and quiet on the Canon EOS 5D Mark IV that we tested the lens with, and manual focus over-ride at any time is a great feature, as is the effective built-in optical image stabilisation system, now worth up to 4 stops rather than the 2.5 stops that the previous model offered. Read the review…

The Canon EF 24-105mm f/4L IS II is expected to ship in the next weeks. Pre-order it at Amazon | B&H Photo | Digitalrev | eBay | Adorama | Canon USA

Canon Powershot G1 X Mark III coming with APS-C sensor? [CW2]

Canon Powershot G1 X Mark III Coming With APS-C Sensor? [CW2]

Interesting rumor that came in (thanks). May the Canon Powershot G1 X Mark III feature an APS-C sized image sensor? According to our (new) source it will.

The rumor has some chance to be real. Actually, the PowerShot G1 X Mark II (and G1 X Mark I) features an 1.5″ sensor. This sensor is 20% smaller than an APS-C sensor (and around 5.6 times larger than the one found in the Canon PowerShot G16). Since the G1 X Mark III always had a pretty big sensor, tending towards the size of APS-C, the company may well have decided to put an APS-C sensor in the upcoming Powershot G1 X Mark III.

The Powershot G1 X III may be announced in Q1 2017. I think it will still have a 1.5″ sensor, but I can’t leave out the possibility of an APS-C sized sensor. What do you think? Sound off in the comments section.

Canon patent for Optical Viewfinder with built-in image sensor

canon patent

Interesting patent filed by Canon. If I got it right, this refers to an optical viewfinder with a built-in image sensor. I did not completely understand what this is for. The parts circled in red in the image above show where the image sensors are. The sensor at (24) is what we know from current DSLR designs. The sensor at (22) is placed immediately above the viewfinder. As usual with patents, I am glad for any additional interpretation.

  • Patent Publication No. 2016-177038
    • Published 2016.10.6
    • Filing date 2015.3.19
  • Canon patent
    • A finder optical system having a reduction optical system and the imaging device
