CANON G15 Review

Introduction

During 2013 I had the opportunity to test the Canon G15 during three ultra-extreme events. The first was in March at the Addo Elephant trail run in the Eastern Cape, the second was in April during the Marathon des Sables (MdS) in Morocco and the third was during October at the Kalahari Augrabies Extreme Marathon (KAEM) in the Northern Cape.

I was surprised how well the G15 coped with the heat, sand, humidity and wet conditions. As both the MdS and KAEM are multi-stage desert races my initial fear was that the sand at both these events may cause the retractable lens to malfunction, this never happened. My second concern was that the high temperatures may impact significantly upon the camera, either draining its battery, or causing some other malfunction, this also didn’t happen. From the outset, therefore, the quality of the camera and its ability to withstand an extreme environment met my first criteria more than adequately. It’s worthwhile noting that although the camera is rated to operate at a maximum temperature of 40 degree Celsius, the MdS showed that this camera can work at temperatures well above that.

Before I delve into a more detailed review, it’s worthwhile looking at the general specifications of the camera:

Look & Feel

The G15 has a solid look and feel; it sits well within your hand which helps with stabilization of the camera when taking photos. It has a sturdy design with easy access to its selector dials and buttons. I found the ‘exposure compensation dial’ to be somewhat in the way which means that I would, on occasion, make adjustments which was not intended.

When using two hands to stabilise the camera during low-light shooting my left hand index finger always seems to be in the way, preventing the ‘popup flash’ from ‘popping-up”. For the rest of the dials and buttons, I had no problem, reaching or using any of them. To be fair, however, one must realise that the G15 is still a point and shoot camera although it has a range of manual features which makes it a highly versatile camera. To pack this manual capability into a point and shoot body is no small feat with body real-estate being very limited. As with most point and shoot, and even armature DSLR’s the popup flash is limited and one could rather make use of a stand-alone flash for which the G15 has a hot-shoe.

Features

The G15 has a host of shooting modes and photo effects that delivers some additional capability to a well-designed camera. It is capable of taking up to 10 frames per second in High-Speed Burst HQ mode, which is really great for outdoor-adventure sport. Some of the shooting modes (such as HDR requires the use of a tri-pod which, in self-sufficiency races are in short supply). In essence not all of the capability will be accessible to photographers that don’t have supporting aids. There are, however, enough features that can be used while on the run. The optical zoom is excellent and provides sufficient zooming capability for close-up shooting to the user, but as with all cameras the digital zoom element has very little value, particularly as it pertains to image quality. For the adventure racer who would like to snap wildlife or fellow runners that may be some distance off, the optical zoom is somewhat limiting.


During KAEM 2012, I tested the Nikon V1, and was able to capture excellent photos of distant subject matter. However, to do so I had carried the V1 body and three lenses with a total weight of nearly three times that of the Canon G15. There are always trade-offs where weight is concerned and for the typical adventure racer the G15 is that balance. It finds the sweet-spot between quality, features, and weight, delivering sufficient capability for most circumstances. 

      

  

Using the G15

Still Images

The quality and sharpness of the G15 provides excellent scope for a range of photographic experiences. The following images were taken during the 2013 MdS and are intended to demonstrate image quality, clarity, sharpness etc. 

In this photo I attempted to convey some information about the intensity of the sun, even early in the morning. The G15 provided the capability for me to frame the picture with the sun as central image without losing the blue of the surrounding sky.

Sunsets in the desert are always uniquely beautiful. In this image the variation in color emanating from a bright whit center, to a yellow and eventually orange spectrum combined with a solid black lower half demonstrates how the G15 is capable of capturing the finest detail without compromising on color or quality.   

The next photo captures a sun-rise about 30-minutes before I completed the MdS long-stage which saw me run through the night. I wanted to show the beauty of the new rising sun, but at the same time convey the message of the desolation, the loneliness, that is found in the desert. Again the G15 was able to deliver. The space, the sun and the variation in colour said exactly what I intended and the G15 delivered image sharpness, colour accuracy and image quality.

In this the final MdS image, I was trying to capture what the Sahara desert is all about, the romantic image of sand dune upon sand dune, the size, the scale and the lack of forgiveness that this environment without trees and shade throws at anyone who enters her. Again the G15 captured in crisp intensity what I was trying to say.

Tanya and I came across this berg adder while running the Addo Elephant in March this year. The G15 did a great job capturing the detail of this beautiful reptile who was somewhat stressed by the time we reached him.

Video

The G15 allows you to take really great videos; the lens provides high quality images. This feature is great for video diarising; however, the battery life of the G15 is greatly diminished when using the camera in video mode. This is an important consideration for adventure racers for whom weight is an important issue.   

Conclusion

The Canon G15 is a lightweight, high quality camera with many automatic and manual features to appeal to all photographers, from amateur to professional. However, its real appeal for the ultra-adventure racer is the balance between the G15’s weight and quality. Here the Canon is in a class of its own; it is robust, easy to use, and compact and produces both high quality stills and video. The few negatives that I mentioned are peripheral and do not detract from the great features of the camera. I can strongly recommend the G15 to ultra-endurance, adventure and self-sufficiency racers who place a high premium on light-weight items. 

KAEM 2013 Pre-Race Report

Introduction

With the Kalahari Augrabies Extreme Marathon (KAEM) in less than two weeks, my race pack has been sorted and is waiting to be carried through the "green desert". After repacking my pack numerous times it is now the lightest it has ever been. Wet my pack weighs in at 10,5kg's on the start time. By the time I start my long run my pack weight would have decreased by 1,54kg's which means that my wet weight would be around 9kg's.     

 

I have shed most of the luxuries, all of which I am confident I can live without for the seven days in the desert.

Below are a number of tables with the specifics of what is in my race pack.

I always carry my food in a pack that seals it from dust, sand and water. This way I am confident that my food remains uncontaminated. I also don't repackage my food but keep it in its original packaging. Possible bacterial contamination outweighs the potential weight reduction that may be achieved through repackaging.  

The following is a detailed composition of my nutrition for the 2013 KAEM. It is based upon my research done during the 2013 Marathon des Sables (MdS). I approach my nutrition and overall weight pack composition from two central points. Firstly the MdS data indicated that the optimal nutrition used during the MdS for males came to 0.91kCal per kilogram of body weight per kilometer of race distance. The second element pegged the optimal race pack weight to runner body weight at 12.5%. 

 

My nutrition came in at 0.93kCal per kilogram of body weight per kilometer of race distance as published by the KAEM team. This exceeds the optimal nutritional value derived from the MdS data by 2.2% which is well within the optimal range that tops out at 1,09kCal/kg per race km.

Race regulations require a minimum of 2,000kCals/day while Basel metabolic rate calculations peg the survival rate at 2,500kCals/day. My total race food energy consist of 19,312kCal which translates to 2,759kCals per day. Although this exceeds the basic survival rate by only 10%, research seems to indicate that this is sufficient, even under extreme endurance conditions. 

Other elements that is important to me besides, total energy value, and the ratio between protein, fat and carbohydrates are sodium and potassium. Research indicates that the body has roughly 8,000mg of sodium in reserve at any given time. Added to this my food contains an addition 37,074mg of sodium, this means that on the start line of the KAEM I will have available sodium of 45,074mg. At an average sodium requirement of around 3,500mg per day, my seven day requirement comes in at 24,500mg. There are, for me, therefore no need to take additional sodium as my food has more than enough.

With only 1,332mg of potassium in my diet and with an average requirement of 75mg/running hour means that my nutrition only has sufficient potassium for 18 running hours. As this exceeds my estimated race time it means that there are insufficient potassium in my food. Potassium supplementation is an option which I still need to decide on.

Nutrition Specifics

     

The following is my daily menu:

To ensure that I start the final race day with the required 2,000kCals as per the race regulations some of the extra food packed for the rest day will stand over to the final day.

With my food sorted and the weight of of it coming in at 4.873kg's I had that basis from which to determine what other equipment to take with. The weight ceiling derived from the MdS research pegged pack weight at 12,5% of the runners body weight. For me that meant that my pack weight had to be limited to 10,63kg's.   

Race Pack Equipment

Presently my pack weighs in wet (including 1,5kg of water) at 10,46kg's. This is 170g less than the MdS suggested ceiling.

The following equipment is included in my race pack, it includes all mandatory equipment plus some additional elements that will ensure that I can deal with the majority of issues that may come-up.

Race Pace

So what is left for me to do is to set a race pace. During KAEM 2012, some inexperience and continued problems with my heels meant that I maintained an average pace of 3,8km/h. During the MdS this year my race pace was slightly faster at 3,9km/h. During the first three days of the MdS I averaged a 4,3km/h race pace, however, with my heel problems flaring up on the long run I had to slow down. Hopefully the inners will last the entire race and I will have my first multi-stage with little to no heel pain...if it does I am setting a race pace of 5km/h.

Conclusion
This is my last posting for October, my next article will be my KAEM post-race report.
