NEX-C3 and NEX-5N

Both have no AA filters. I searched.

Only the dust shaker that is also the UV-IR cut filter (a mere 0.6mm thick) is present.

The NEX-5 has a stacked/glued AA filter/UV-IR/dust shaker (Peter Ganzel showed the thickness to be 1.1mm).

I don't know about the NEX-3 (or the new F3).

The NEX-7 has a separate AA filter (0.5mm thick) and the UV-IR/dust shaker 0.6mm thick).

real??? This is very good news if nex 5n has no AA filter, it means the Nex 5n is a fraction closer to the likes of the Leica M8 M9 DMR all which seem to not have AA filter and results in exceptionally sharp images

Why would I post something that is not "real"?

Normally, when I remove the UV/IR/AA stack from a sensor, I can see moire in Visible, UV or IR, readily. No such thing in these cases.

I am not sure if the NEX-C3 or 5N are closer to the Leica offerings but surely they only cost a fraction! ;)

A few good reviews have been done of the Nex 5n against the Ricoh M-mount which is a good bench-mark for no AA (Ricoh states that it is so). They use the same Sony sensor.

Ricoh M mount lensor has a 16MP sony sensor?:confused:

Thanks Vivek - it's definitely old age creeping in (but I've been saying that since I was 21).

The 12MP Ricoh M-mount Sony sensor has been reviewed a number of times against the 16MP Sony sensor in the 5n. The reviews I've seen have rated the Ricoh higher in IQ with extreme pixel peeping. That 12MP Ricoh sensor has no AA.
The Ricoh A16 zoom does have the same 16MP sensor as the Sony 5n and also has no AA. The only detailed pixel peeping snap review I've read of the 12MP m-mount against the 16MP Ricoh A16 is by Sean Reid and you have to pay to get it. He rates the Ricoh A16 as his benchmark for APSC.

I have all three sensors and can't tell the difference on any image I've posted on this forum. I love all three, but on my Apple cinema display I prefer the A16. But I love my Pentax K-01 and K5 images almost as much.

Please take my input with a pinch of salt though. I'm the kind of guy who would swear his car is going faster after a car wash. Seriously - it happened to me this morning.

Hope I've got it right this time . . . duhh

Hate making mistakes in public :deadhorse:

Hi Keith,

I simply did not understand your post (other than the MP count). Did any of the reviewers look inside the cameras to verify the presence or the absence of the AA (blur component) filter? I did and hence this thread.

Cool, Vivek. It seems that this is the likely the reason for the big difference between the 5N and 7 with symmetrical lenses.

FWIW, I have compared the same scene with the GXR and 5N, using the Voigtlander 15, and the Voigtlander 15 has better edge detail and less color shift on the GXR, so Ricoh still has an advantage with wide, symmetrical lenses, even if both cameras don't have an AA filter.

BTW, were you able to use the NEX-7 without the AA filter in place?

Does this imply that by removing the AA filter the NEX-7 would be as good as the NEX-5N using symmetric wide angles?

Hi Douglas,

I never challenged any other cameras (sharp, blurred) that I have no experience with.

With only one screw holding the shutter mechanism in the NEX-5N, it does not need a blur filter. So, it makes sense to me in terms of cost cutting.

My opened NEX-7 has to wait a while after my vacation to make it working ( I know what went wrong during reassembly) besides that, now, I have broken the battery compartment door (still should work without the door) during an accident. I have a replacement I bought from Jono. It still is in its original shape.

Does this imply that by removing the AA filter the NEX-7 would be as good as the NEX-5N using symmetric wide angles?
That is one possibility (check the other thread: http://forum.getdpi.com/forum/sony/38930-nex-7-has-aa-filter.html). The other being the baffle inside the NEX-7. I have widened mine. Results await successful reassembly (will take a while).

I am not sure I understand why a camera having an AA filter or not is good or bad news. After all,it is the pictures that matter. Either they have great detail, or they don't. If they do, does it matter why they do, and if they don't, does it matter that we know why they don't? My NEX 7 has stunning detail, yet it seems to have an AA filter. Would I be happier to learn that it hasn't got any, a la Leica? I rather think not...

I believe the main thrust is that sensor toppings, like AA filters, can lead to more astigmatism with highly angled light rays as you go towards the edge of the sensor. The NEX-7 behaves oddly with some M lenses, and there are some claims that it could be better even with some SLR lenses. If the NEX-7 has a sensor topping that the C3 and 5N don't have, it's an interesting development.
