As a reader, I always keep in mind that the corner results are Nex-7 specific. Unless there is a proof that the results on Nex-6 and Nex-7 are the same, all of the tests on Nex-7 are valueless to me. It is a waste of time and money.
Ahem, please stay real here.
At the time the NEX 7 was released we were cheered to started testing on it immediately.
I also didn't use it for testing because it was apparent that there might be problems.
A 24mp APS-C sensor is highly ambitious just by the numbers. The center resolution will always be much better than the outer region. This alone is not specific to Sony and will show up as a problem on all systems eventually - this is not about us here. Sony was first to push it like that.
Whether the 24mp sensor has specific issues is something that we have to investigate. I just had too little time for this lately.
You are right that I am somewhat negative about NEX in general. But this is less so because of the camera - you may remember my rather enthusiastic comments in the beginning - but because of the lens centering issues that we are facing: the defect rate is the worst among the systems that we test. The manufacturing quality IS a decision point for consumers so we have to communicate this. Existing NEX users have a problem with this - this is just normal since they tend to be loyal because of their system decision.
Now as far as the flagship discussion is concerned - the reason for choosing a camera for testing is taken at a point in time.
The EOS 5D, D3x, 50D, NEX7, GX1, X-E1/Pro1, NX200, D7000, A900 were all the highest resolution cameras at the time of purchase. You all know that we will not jump ship once a new model emerges. A decision is valid for about 3 years since the investment has to pay off first.
And regarding the 10-24/4 ... the MTFs are actually quite good. Same goes for our rating (for a lens in this class).
The 50/1.8 is also very decent and the 35/1.8 looked promising ... apart from its centering issue so this one is on the way to Sony service once more.
Whether you think that the tests are useless or now is, of course, up to you. We just test following the same standards across all systems.
Klaus, just about half of the Sony E 10-18mm lens tests I have seen say something along the lines: "the lens is clad in high quality plastic, including the filter threads", the other half, including you, say: "It has an all-metal body". Could you please confirm that the lens has all metal body? Thanks!
Yes, I strongly suspect that there is a issue but as some of you pointed out I haven't proven it.
If there is an issue, this doesn't invalidate the tests though. It just means that you have different scaling factors compared to the 16mp sensors - both in the center as well as at the borders. e.g. In the center you may have a difference of -say- +25%, at the borders it may be +5% and at the corners it could be -5%.
Or in other words - the lens ranking will not change just by testing on the NEX 6.
Come down, it's a review, not a declaration of the pope. There are many review sites for Sony NEX lenses on the net and there still more images. Actually I'm looking more at the images than on the reviews.
