Long one of the dominant players in the world of high-end film cameras, Canon’s entry into the digital world has been measured and cautious. With the introduction of their PowerShot A5 model in mid-1998 though, they clearly advanced into the ranks of leading digital camera makers: The tiny A5’s attractive, compact format and high-quality imagery have helped make it a big success with consumers. Now, with their PowerShot Pro70, Canon has aggressively moved to expand their position into the high end of the “prosumer” marketplace for digital cameras. To that end, the Pro 70 incorporates a number of features that uniquely suit it for professional use, particularly for in-studio shooting.
PowerShot Pro70 “High Points” overview
Several readers have requested quick, up-front feature summaries of the cameras we review, which we’ll be doing from this point onward. Herewith are the key characteristics of the Canon PowerShot Pro70, ranked in a completely arbitrary order reflecting our own personal biases and dispositions ūüėČ

  • 1.7 megapixel CCD sensor
  • 2.5x zoom, with equivalent focal lengths ranging from 28-70 mm
  • Works with sophisticated external auto flash unit, including flash-head zoom and EV compensation
  • AP (Aperture Priority) auto-exposure mode, truly independent of shutter speed
  • “CCD Raw” mode for totally uncompressed images
  • “Review” mode holds last image on LCD screen as long as shutter button is depressed
  • Tilt/folding LCD screen is¬†very¬†handy in studio – we liked the option of positioning it to the side of the camera, or directly on the back…
  • Optional remote release¬†very¬†handy in studio for long exposures
  • Superb low-light capability
  • AF-assist illuminator guarantees accurate focus in any light (giveaway of AF light will prevent candids though)
  • Phase-differential passive autofocus is very accurate
  • Fine-grained exposure-compensation adjustment (1/3EV steps) a welcome feature
  • Dual CF cards for mondo in-camera storage. (Also supports Type II CF cards – should handle IBM 340-megabyte microdrives when they become available)
  • Fairly fast cycle times (max of 11 seconds for uncompressed mode), for such a high-resolution camera.
  • Average shutter delay, but very fast (0.2 seconds) if pre-focused
  • Excellent ergonomics, very stable camera platform
  • Works well with Canon dedicated speedlights, possibly usable with 550 super-speedlight? (multi-unit auto flash operation)
  • NiMH battery pack provides high power, rapid charge
  • Very fast, responsive menu system
  • Standard 37mm filter threads for aux lens mount
  • Very capable automatic white balance, works in virtually any lighting
  • Wider angle lens, plus low light capability, plus external flash integration make for a superb “indoor” camera!

Overall, the Pro70 is an extremely strong offering, but there are a few things we’d really like to see in a camera of this level and target audience. (None of these are “fatal” flaws, but all would be useful to the Pro70’s target audience):

  • Spot Metering
  • Manual white balance settings
  • Faster autofocus
