DP Review S90 brief hands on: http://www.dpreview.com/news/0908/09081906canons90handson.asp

 

Evaluation Context:    Overlanding / Expedition use

 

Purpose of this evaluation: Provide initial impressions and testing results of the S90 compared to other Canon “point and shoot” compacts, pro-sumer and professional cameras. For full technical testing of the S90, please see DP Review or other sites.

 

Background:

I’ve been shooting digital since the late 90s. I moved from Sony to Canon when I returned to shooting with SLRs in 2003. We have owned more than a dozen Canon still cameras since then, and have overlanded with them in six continents.

I have owned and used a Canon SD / Digital Elph since the product line was introduced.

 

Purchase purpose:

Replace my SD870is, which still works fine, but I put two black spots on the display by burning it on a sunset in Chile in mid-2008.

 

Current inventory:

Me:

• Canon 1D MkIII

• Canon 1D MkII

• Canon G10

• Canon SD870is

Wife:

• Canon 40D

• Canon 30D

• Canon SD880is

 

Utilization criteria:

The S90’s purpose is to take the role of pocket/jacket camera. I typically store this camera in a belt pouch or in my motorcycle jacket front pocket.

In our world of travel and everyday use, the pocket camera is used for:

• Grab shots

• Records shots

• Snapshots

• “Please take a photo of us here” shots

• Stealth shooting where the big SLRs draw too much attention/risk

The most important role the pocket/jacket camera plays for us is that it is always there. The most important camera you own is the one you have with you. In that sense, our pocket cameras have always been the most important cameras on our travels.

 

Evaluation Criteria:

Overlanding / expedition use places different demands on a camera than stateside suburban utilization. Aspects of design, packaging and efficiency can be much more important in the bush than back in the ‘burbs. For instance, the ability to share common batteries and chargers between multiple cameras can mean a lot when picking new or additional cameras. Small details of ergonomics and use, such as control placement and consistency of menus become very important in high stress moments in remote areas. And of course, rock-solid reliability is critical, since the repair depot is thousands of miles away past multiple customs officers all eager to delay the shipment and tack on expensive duties.

 

Methodology:

The evaluation consists of handling the camera, stepping through the menus, shooting some test shots and comparing it with other Canon cameras for size, weight, ergonomics and performance.

 

Cameras in test:

• Canon 1D MkIII

• Canon 40D

• Canon G10

• Canon S90

• Canon SD880is

• Canon SD870is

 

Size comparison:

L to R: SD870is, S90, G10, 40D, 1D MkIII

 

System size comparison:

A camera is not just a camera. When you are traveling with a camera, you are also traveling with its family of chargers, batteries, memory cards, bags and accessories.

In this shot, the S90, G10, 40D and 1D MkIII with 580 EXII strobe are shown with their respective batteries and chargers. Note that the S90, G10 and 40D have integrated stobes. The 1D MkIII requires an external flash, along with its supply of batteries and/or external power supplies.

This shot adds samples of typical bags used for the respective camera systems. The S90 is shown with two varations: a slip case (used by my wife in her purse) and the belt pouch I typically use when we’re not traveling by motorcycle (the small Sandisk pouch is used to carry an additional battery and memory card).

 

Ergonomic and control differences SD870is vs. S90:

The S90 is nearly identical to the SD870is it replaces in size, shape and weight.

The primary differences are the lens control ring protruding from the front and the top control dial. There are also some differences in the rear controls, with the removal of the ISO position from the rear control dial the most significant for day-to-day use.

The lens control ring is a huge improvement in camera control in this form factor. Software configured, it can control six different functions. This additional control input is something this class of camera has sorely lacked until now.

Two major downsides to the new design are mostly related to the “Please take our photo here” scenario. The S90 has a very small power button and a small shutter release button. Just about everyone you hand this camera to will attempt to push the top of the control dial to release the shutter.

One significant improvement in ergonomics is the thumb rest located beneath the control dial on the back side. It provides a natural place to rest your thumb and greatly aids one handed operation.

 

S90 vs. G10 Comparison

 

The G10 has a smoother and easier to control power zoom. It is possible to set the framing on the G10 with more precision than with the S90.

The G10 is significantly larger, but does not weigh that much more than the S90.

The G10 is a (very) large pocket camera, more suited to a big belt pack than a pocket. The S90 is a true pocket camera.

The G10 has more direct dial controls than the S90. I find it easier to control the camera with direct button or dial controls than via a menu. The S90 makes significant inroads here with the lens control dial, a feature the G10 lacks.

The G10 includes an optical finder, while the S90 is limited to the rear display.

The G10 also features a hot shoe for external flash and a higher pixel count at 14.7. Published reports state that the G11, the current model replacement for the G10, uses the same imaging chip, and thus resolution, as the S90.

Of the two, the G10 is more suitable for a serious hobbyist or “pro-sumer” who requires an optical viewfinder and/or is interested in exploring the capabilities of external flash and prefers direct camera control via buttons, knobs and dials.

For the shooter who is looking for RAW format, manual focus, multiple operating modes and other pro-sumer capabilities in a smaller package, the S90 is the perfect choice.

 

Capabilities:

The S90 is packed with pro-sumer capabilities in a very small package. Based on years of overseas overlanding and expeditions, of greatest interest to me are RAW format files, manual focus capability, and P, Tv, Av and M modes. While we assume that high ISO performance will always get better with new cameras, we could not assume that manufacturers would ever push down fundamental capabilities from the higher end cameras to the pocket camera world.

The ability to post-edit the RAW file is critical to saving borderline images from tough shooting situations. Manual focus provides the opportunity to selectively compose an image in a very small camera. Multiple operational modes that match pro-sumer and pro bodies enables you to utilize consistent mental models and creative paths regardless of the camera you happen to have along that day.

If I could have had any two of these three capabilities in this camera size during our last two years overlanding I could have brought back significantly more successful images.

 

Conclusion:

Based on features and capabilities, the S90 is the camera I wish I could have taken with us for the last two years.

You can make your own judgments on the image quality tests which follow.

I will post additional thoughts after I’ve used the camera in the field.

 

Test Parameters:

Setting: Interior, multiple light sources (some daylight, two different color temperature fluorescent), static subject, static tripod.

Because it is essentially impossible to match framing with power zoom cameras, I chose to maintain a consistent camera to subject distance of 115 cm / 45.25”.

I tested the cameras under consistent lighting conditions and shot each with and without strobe.

All cameras were set to auto white balance and evaluative metering.

Auto focus was used on all cameras for all shots.

Camera self timer mode was used for shutter release for all shots on all cameras.

Because the higher end cameras can operate in Av mode, I shot two sets of images with the mid-range cameras (S90 & G10). The first set is in P mode to match the 870is’s P mode of operation. The second set is in Av mode at F5.6 to match the higher end cameras.

The 880is and 870is generated largest size, lowest compression JPG files. The S90, G10, 40D and 1D MkIII all generated RAW and largest size, lowest compression JPG files.

The full frame RAW and JPG files are unedited and unaltered in any way. The 800 pixel shots used in the text are sharpened for screen viewing.

All selection, editing, etc. was performed in Adobe Lightroom 2.5, Camera Raw 5.5. LR handled the S90 RAW files with no issues. File import was via Breeze Systems Downloader Pro V2.2.2.

The primary light sources were two different Ott-Lite sources, one with “HD” bulbs and the other using their “natural” bulb. You will notice the wide variation in color balance in these shots. Overall, the 1D MkIII shots are closest to the actual colors as my eyes perceive them.

The SD870is and SD880is only have P mode, so there was no way to preset the aperature. I matched the P mode in the S90 and the G10 so people who are looking to move up in capability from a pure “point and shoot” compact could see and compare that upgrade path.

The 5.6 shots were done in Av mode to match the 40D and the 1D so people looking to retain creative capability in a smaller camera could see that migration path.

Please Note:

All images are unprocessed, unedited and unaltered.

The full rez JPGs are factory default output from the cameras.

The RAW files are unaltered.

If you want to compage with an image from a camera you own, be sure to process the files accordingly, e.g., if you normally apply sharpening, alter black levels, etc.
