Nex7 noise performance is simply fabulous
Re: Nex7 noise performance is simply fabulous
Fascinating. Thank you both. So for someone like me, whose primary concern is one shot picture quality (ie no continuous shooting) and not bothered about AF, the NEX-7 would appear to be a better choice than the a77 (assuming lens quality equivalence).
But what about the NEX-5N + ported EVF vs NEX-7 for such a user?

Re: Nex7 noise performance is simply fabulous
If you are happy with the smaller file size, the 5N is cleaner than the NEX-7.
It's better at 1600, but not as good at 3200 as the 7 is at 1600. Sadly, the 55-210mm zoom I used with the NEX-5N was not very sharp at 55mm so any results I have are not fair comparisons.

David, the 7 is MUCH cleaner than the 5N.
The problem is - they don't sell the thing.
So for now... ,

Re: Nex7 noise performance is simply fabulous
Thanks again both of you. It sounds like a close call so I shall wait until I can try them both out together to see which proves the more ergonomic for me. May be a bit of a wait...
(As for file size, the nex-5n at 3:2 raw would give sufficient resolution for a 69x46cm print at 180dpi, which is, I have been told by an Epson instructor, one of the two optimum resolutions for prosumer Epson printers such as my R3000 or the 3880 (the other being 360dpi but impossible to tell the difference except on really big prints). Thus, it would permit a bigger print than either of these can manage. So I would be happy enough with 16 Mp but the N7 may have ergonomic advantages - we shall see)

Re: Nex7 noise performance is simply fabulous
The nex7 shot has so much more detail, David is this due to the lens ? Or is It due to how Sony are using the sensor in the A77? I wonder how the nex7 goes with the slt based adaptor ?
David does the a77 shot show the sort of detail you would expect for that shot and that class of camera ?
I.e is the a77 performing has expected and the nex7 better then expected? or the other way around?
If the same photo was taken with say a 7D. Where would the 7D lie, closer to the a77 or nex7 ?

Re: Nex7 noise performance is simply fabulous
No, it's due to the poor performance of the 16-50mm f/2.8 - it's not as good a lens as the SEL 18-55mm, that's all. Many of my shots with the 16-50mm samples were worse than this by a long way. I thought it might be down to prototype issues but I hear some buyers have got very poor lenses.

Re: Nex7 noise performance is simply fabulous
This means I should not cancel my pre-order and wait . Nice feedback ! thanks.
Until this camera can be my best friend in the range of ISO1600-3200 and some ISO4000 for low concert shooting I will be more than happy.

Re: Nex7 noise performance is simply fabulous
So the 'Dark Age of Ugly System Camera' is upon us already, or so it should seem if we all have to use Nex+adapter just to get some decent image quality with Sony...
Take a look at some 5N below, the 7 won't be too different - just a bit more unbalanced...

Re: Nex7 noise performance is simply fabulous
Seriously, though, those more serious Nexes simply cry for some 'battery compartment with grip extender' if not a full VG.
The batteries could be arranged like that, would fit - I checked -

Re: Nex7 noise performance is simply fabulous
Hi Agorabasta - is that the new Sony LA-EA2 on the 5N? The permanent tripod mounting point looks better than the separate one on the LA-EA1. My LA-EA1 has a small amount of movement when mounted on a tripod, which is not ideal for tripod work .
I like the idea of being able to combine the components like this in a system camera, but the result is not going to win any beauty awards .

Re: Nex7 noise performance is simply fabulous
Hi, Birma. Sure it's the EA2, it even says so on the sticker below - see the second adapter pic
BTW, I'm getting 0.4-0.3EV light loss at the mirror, depending on the diameter of the lens rear element. Some f/1.4 lens get 0.4EV hit, a typical superzoom gets slightly below 0.3EV, the SAL 18250 at 250mm gets exactly 0.27EV loss. That's all from direct measurements using the AEL on 5N, then matching the exposures in Lr.
And there's no ghosting, just like with a77...

Re: Nex7 noise performance is simply fabulous
Thanks Agorabasta! I was looking at the tripod mount so much that I missed the writing next to it . I haven't seen any rumours yet as to when the firmware on the older Nex cameras may be updated for the LA-EA2, have I missed anything?agorabasta wrote:Hi, Birma.

Re: Nex7 noise performance is simply fabulous
Thanks Agorabasta. The Sony UK site is listing all Sony Nex cameras as compatible, it also mentions a firmware being required, but no hint to dates yet. At £270 I am almost tempted.
