I’ve been a Choice member for decades, and rarely have I felt the need to criticise the organisation. However, on the subject of camera tests, I’ve the written to Choice a number of times with no effect - so I’ll try this forum.
Choice’s tests of high-end cameras are basically worthless, and they should stop.
Firstly, the test as a survey of cameras is far from complete. Where are the high-end Canon cameras? If the top of the line Sony and Olympus cameras and the Nikon D850 are tested, so should the Canon 5D.
Secondly, testing semi-pro cameras like the Nikon D850 on criteria appropriate to a point and shoot wastes everyone’s time. It’s like comparing a Ferrari with a Kluger and marking it down because the Ferrari doesn’t tow a caravan as well as the Toyota.
Actual test results are questionable. For example, the test’s Picture Quality Score has the Nikon Z6 rated at 90% while the D850 is rated at 67%. How that result was arrived at, I can’t imagine. Part of the problem might lie in the fact that the lenses used to compare the Nikons aren’t the same or even equivalent, so little can be assumed from image scores.
Choice also needs to be more careful in its basic facts. Comparing three Nikon models (D850, Z6 and Z7), I note that:
- Lens mount for the Z series is noted as “not applicable”. This would imply that they are not interchangeable lens cameras. In fact, the Nikon Z cameras use (surprise!) Z mount lenses.
- The Minimum Shutter Speed for all three Nikons is shown as “31/12/7999 1:00:00 PM”???
- Image ratios supported for the D850 is given as “29/12/1899 4:02:00 PM”. What??
By all means, test cameras. But test consumer cameras with appropriate, consumer criteria and leave testing of pro and enthusiast cameras to those with the resources and the interest to test them appropriately.
