Olympus Camedia C-7070WZ

A better '5060?

My other pages related to the Olympus C-5050Z, C-5060WZ, and X-7070WZ

Following a number of requests from Readers, here is a very brief discussion for the C-7070WZ digital camera from Olympus. It is not a full review, as the '7070 is a non-identical clone of the previous model, C-5060WZ, from which it differs only in a very few specs and features.

Because of that, here I will focus on differences between two models, as my '5060 review has been updated to become fully applicable to the newer model.

Keep in mind that I had the '7070 only for a weekend, being unable to come up with any meaningful image samples. For comparisons and trial prints I used the samples provided by Steve's Digicams, being among the most consistent ones available on the 'Net.

More pixels

The main difference between the both cameras is that the new model has a sensor with more pixels. Here is a detailed comparison, with the '5060 numbers in parentheses.

  • Nominal pixel count, as claimed by manufacturer: 7.1 MP (5.1 MP)
  • Image size in pixels: 3072 × 2304 (2592 × 1944)
  • Actual pixel count: 7,077,888 (5,038,848)
  • The same, in "binary" MP: 6.75 (4.81)

This means that the increase in pixel count is about 41%, which translates itself into a 20% increase in print sizes possible at similar quality (assuming the lens is good enough). In reality, this is usually not the case. Still, the images from the '5060 can be converted into good prints at 12×16" (30×40 cm), large enough for my needs, and the '7070 can only do better.

More pixels at the same imager size means smaller pixels. Smaller pixels mean more image noise — but most people overlook the fact that this is more noise per pixel, not per print area unit. At the same print size, the '7070 noise is less magnified (by 20%), and I could not really see a difference here between both cameras.

Camera construction and layout

The body design and construction quality are the same as in the '5060, where they were very good, except for a design error, causing the infamous mode dial problem which seemed to be quite common. Obviously, the problem has been addressed in the '7070, as I haven't heard from anyone suffering from it.

Anyway, the '7070 has the same sturdy all-metal body (magnesium alloy) and well-placed controls. The body is a tad too large for my taste, but, still, I like it.

The only visible difference, in addition to the new logo, is that individual "scene modes" have been removed from the mode dial and replaced with just one position, marked as "Scene"; the actual choice is done from the menu system. The redesign might have been needed to get rid of the problem mentioned above, but I actually prefer it this way.

Overall, a professional-grade job, hard to match by anyone else.

Minor modifications

These are mostly of secondary importance or even less; I consider only the first one relevant.

  1. Color hue adjustment in addition to those in sharpness, contrast and saturation. Most reviews got it wrong: this is not duplication of the WB (color temperature) adjustment, as it works in the Green/Magenta plane. Although not critical, this is a nice feature.
  2. New AF mode, in addition to those inherited from the '5060. It is referred to as "Oracle mode" and really means predictive AF. Obviously, it is intended to be used with moving subjects, but I haven't had a chance to try it out and I cannot tell how useful it really is.
  3. Red eye fix: a new option in the in-camera image editing, available in the playback mode. I haven't tried this either. Those who do not postprocess their pictures may find the feature of some use, although it is clearly aimed at the beginners' market.
  4. Control dial operation. For those who may not be happy with the standard mode of operation (turn the wheel while a button is pushed), there are two other options: (a) press the button, let go, and turn the wheel within a "grace period"; (b) press the button repeatedly to scroll through various options for the corresponding setting, without using the control dial at all. The last approach requires the use of cursor keys in some cases. The option (a) is how the system works in the E-300 and E-500 SLRs.
  5. New menu look. Yes, the new menu scheme looks brighter and somewhat more readable, but the basic layout remains unchanged; all my remarks on the '5060 are still valid.
  6. Frame composition aid: Referred to as "Frame Assist", this superimposes on the previewing screen either a 3×3 grid, or two crossing diagonal lines. The former may be useful in some cases, the latter not very much. (The original '5060 could show the grid or a head outline, but the feature was removed in one of firmware updates; the latest version shows the grid only in Play mode.)


As you could see, the list of changes is rather short. This is good news, as the '5060 is a very good camera, and there was no real reason to change anything (except of fixing the mode dial problem), unless Olympus decided to address one of the larger issues, providing the new model with a better viewfinder and/or increasing the lens aperture at the long end. This would, however, make the '7070 an entirely new design.

On the other hand, the market grew used to having a new, "improved" model of the same line every year, and I think Olympus was desperate to come up with one. Throwing in more megapixels is not so expensive, neither are the other improvements we have seen. Besides, the '7070 dose not carry the malodorous stigma of the mode dial problem.

All this aside, the C-7070WZ would be still my top choice for a user who needs a pro-grade, non-SLR model for good handling, full control, and serious results.


The '7070 became available around February, 2005. As of this writing (early October) it seems like the camera has disappeared from most stores (this was preceded by a price rise, at least at B&H). It is no longer listed by two biggest U.S. merchants: B&H and Adorama, although the Japanese and U.S. Olympus Web sites still show it among current products.

We may suspect that Olympus decided to pull the plug on the '7070, for reasons unknown. Maybe the model was offering too narrow profit margin: good lens, all-metal body, solid construction — most of that wasted on the mass market anyway.

The recently announced SP-310 and SP-350 from Olympus (7 and 8 MP, respectively) are clearly addressed at the less-demanding market, with the zoom lens starting at only 38 mm (not 28, a huge difference!) and the body construction being a far cry from the '5060 or '7070. The new models may be more appealing to a typical consumer, but I'm not thrilled with them at all, in spite of larger and more readable LCD monitors.

My advice: if you need a serious non-SLR camera, try to find a dealer who still has the '7070 in stock and snatch it before someone else does.
