Noise – I cant hear a thing……..

The final review I have considered doing on the two aspects of the new Canon 5 D MK III was about its noise performance at the higher ISO. Performance of my equipment at higher ISO settings it is an important tool in the getting maximum out of the low light situations I regularly find myself inNocturnal Landscapes , Wildlife and Live Music ) BUT  it is not the deciding factor of what or when to shoot but merely a tool to improve the final product for the viewer and of course ME ! The new improved system from CANON is exceptional and has added a new dimension to exposure boundaries in low light ! Unfortunately  , ” noise ” has become a seriously unhealthy obsession for some photographers out there and has been the main criteria they have used to rate image quality…..even above the real photographic facts like composition , exposure and subject mater. Don’t loose sight of these important criteria when getting out into the field !

I did two separate tests……….the first being in a low light music studio with constant light and static subject. The room was light with 2 standard ceiling mounts lights and two wall mounted lights with basic editing and NR in lightroom. I was impressed with the performance and that you can really push the ISO to extremes.

CANON 5 D MK III – ISO 3200 , F5.6 , 1/30th sec

CANON 5 D MK III – ISO 6400 , F5.6 , 1/60th sec

CANON 5 D MK III – ISO 12800 , F5.6 , 1/125th sec

CANON 5 D MK III – ISO 25600 , F5.6 , 1/320th sec

The second test was to shoot at a live gig with below average stage lighting , smoke machines and dark auditorium . Due to the nature of the time available I concentrated on the images I needed but managed to snap this on a test ISO image. The lighting and colours in the stage area were very purple and red . The fact that this is more than useable on web work is awesome. I have made a print and am really happy with the result :)

CANON 5 D MK III – ISO 25600 , F2.8 , 1/640th sec @ 150 mm FL

I was not disappointed in the imagequality and compiled a slideshow of the images i submitted to the band . Thanks to RAF for the use of there title track ONE on ONE……..The majority of the images were shot on ISO 6400 and about 20% on 3200 when movement and positions of members was reasonably static. I have some at ISO 12800 and ISO 25600  as a comparative sample but got more than enough shutter speed at the ISO 6400 settings and image quality . Basic image editing and NR only. Camera settings on manual and varied but constant F2.8 aperture used…view the highest settings for optimal quality :)

I hope you found this interesting and get out there and capture life , one frame at a time – Peace n Light AA

 

Canon – Raising the Bar

CANON 5 D MK III – After many months of rumors and speculation , Canon launched a new camera with great specifications . It is a great upgrade on its current flagship camera , the CANON 5D MK II .

My initial thoughts on this cutting edge Canon DSLR………….It opens huge avenues for me in low light  , cutting edge focus tracking system and also with the 6 frames per second for that intense action moment with the quality of a full frame sensor . The biggest aspect of interest besides awesome ISO capabilities is the new focus system. These are all based on the specification made available today but knowing Canon , this is sure to exceed the paper test :)

All new 61-Point High Density Reticular AF

The newly designed 61-Point High Density Reticular AF features an Offset Array Sensor (with staggering AF point arrangement) to deliver greater accuracy, no matter the situation. It offers multi-zone wide-area AF for better tracking, has 5 central dual cross-type points (f/2.8 diagonal), 21 central cross-type points (f/5.6 horizontal & vertical) and 20 outer cross-type points (f/4.0 horizontal), and is sensitive in extremely low-light situations (EV-2 for a central point with a f/2.8 lens). A dedicated AF menu tab, so AF can be controlled without having to go through custom function menus. It also has 6 AF point selection methods (Spot, Single Point, Single + Adjacent 4 Points, Single + Adjacent 8 Points, Zone Selection, and Automatic AF Point Selection), plus a dedicated AF configuration tool for control of AI Servo AF III tracking parameters (tracking sensitivity, acceleration/deceleration tracking, and AF point auto switching).

 

Capturing Surfers and wildlife at sunrise or sunset with this new Canon Flag ship unit will now give me at least an extra 2 – 3 stops to light to work with. Nocturnal landscape imagery is also a passion of mine and I really look forward to capturing the African night skies with this quality beast .It would seem that this full frame sensor will become a new all rounder and not only a studio/landscape camera as it’s predecessor as the improved weather sealing and construction will add even more value to this awesome canon DSLR

14-bit A/D conversion, wide range ISO setting 100-25600 (L: 50, H1: 51200, H2: 102400) 

The EOS 5D Mark III not only offers 14-bit signal processing for excellent image gradation, it delivers higher standard and expanded ISOs, and a score of new options to enhance shooting in varied and fast-changing lighting situations. With a standard range of ISO 100-25600, the EOS 5D Mark III represents a 2-stop increase in sensitivity over previous cameras. Thanks to the improved signal-to-noise ratio of the new sensor and powerful noise reduction, the EOS 5D Mark III can shoot at expanded sensitivities down to ISO 50 (L) and up to 51200 (H1), and even 102400 (H2)! Beyond the obvious advantages of its wide ISO range, the EOS 5D Mark III has automatic ISO settings, found on the dedicated ISO menu. Minimum and maximum ISO settings can be specified, as can a user-defined range, plus full auto and manual.

DIGIC 5+ Image Processor for enhanced noise reduction and blazing processing speed 

For a whole new level of performance, the EOS 5D Mark III uses a DIGIC 5+ Image Processor. Working with two 4-channel A/D converter front-end processing circuits, and delivering speeds of up to 6.0 fps (RAW + JPEG), and the DIGIC 5+ Image Processor improves data processing performance and features new algorithms that promote greater noise reduction at higher ISOs. In addition to conventional image processing functions the DIGIC 5+ Image Processor offers real-time compensation for chromatic aberration in both still and motion images. With the power of this processor, speed improvements are noticeable from the instant the camera is turned on and the stunning results speak for themselves.

I many genres  of photography and  still life , studio , motorsport and music photography will be greatly enhanced with all of the cutting edge technology.I am extremely excited about getting unit and look forward to getting my grubby paws on it and testing it in the field as soon as they become readily available. It will also slot in just below the leader in the Canon DSLR brand , the 1 D X…………
