Re: canon 100-400, when it will be testet?
I consider your service very valuable. I no longer choose a camera or a lens without first consulting your test results. For example, I own a Canon 100-400 zoom lens since many years. I have since moved to a Nikon D800e with a Nikon 85mm and a sigma 35mm. I am looking for one or two telephoto prime lenses for my D800e to replace my Canon 5D camera and zoom lenses.
But I am now at a standstill for two reasons:
You have no data on the Canon 100-400.
You also have no data on Nikon telephoto lenses, zoom or prime.
I think that you guys are spreading yourself too thin and possibly working by the wrong priorities.
I do not understand why you test the same lens on 10 different cameras. Yes, I understand that there is some interplay between camera and lens and occasional surprises in a combination. But the cost of what you are now doing is that you do not have time to produce the results that we are waiting for.
You need to streamline your priorities:
1. Test all camera sensors as you presently do.
2. For each manufacturer select the top sensor and make that camera your lens test vehicle. Nikon D800E, Canon 5D3 etc.
3. Now use your database to establish a relative score factor for each lower score camera of each manufacturer. This should be expressed as a percentage of the top camera of each manufacturer.
4. Test lenses on the above top cameras. DO NOT test lenses on second or lower ranking cameras. Instead use the above relative performance percentages to predict a result.
5. If you later have time to refine your test results, fine, do that.
6. BUT FIRST WE NEED A RANKING BETWEEN CAMERAS AND THEN WE NEED RESULTS ON ALL AVAILABLE LENSES TESTED ON THE TOP CAMERAS FROM EACH MANUFACTURER.
