Of course, with fix-focal lenses, they can only get it wrong for someone, no matter which focal lens they choose.

If you really want 21+30, then 24+50 is wrong. No question about that. (There is also a 30/3.5 Macro now available if you can live with its slow aperture and probably even appreciate its 1:1 macro feature. Personally I'd have liked this to be a 30/2, and even as a macro lens it really should at least be a 30/2.8.)

Time will tell if there will be a sufficient lens choice for the NEX so that everyone could get what he or she wants, as with Leica M, for example, where everything up to about 90...135 mm is covered by several manufacturers in the smallest possible focal length increments.

By that time, hopefully also the new "G" standard zoom has emerged. BTW there are some image examples at dpreview.com taken with the already available 18-55 kit zoom. I personally don't care too much about the performance, and I strongly dislike the built of this lens: Metal on the outside, okay, but *inside* where it matters most, its really wobbly plastic.... but still that kit is surely not bad in general terms and far from useless on the 24 MP sensor.

If you want to call all this "pocketable" .... well it won't fit in my clothes pockets, that is for sure, but then, I consider nothing else than a slim mobile phone really as pocketable in this strict sense. (Other people might have clothes with bigger pockets. Smiley) However, the NEX would still offer considerable downsizing when compared to a typical DSLR outfit, in at least the same sense that a Leica M outfit does. I need a seperate camera bag anyway, no matter which camera system, but with the NEX, this bag will be lighter and smaller as with my DSLR, and I appreciate that very much. Last not least, the NEX-7 seems to offer really nice handling. So, again, they have just found the *exactly right size* at least for my preferences, and everyone's elses mileage may vary, as always....

Erik...Thanks for your perspective on my ponderings. I located what seems to be an appropriate tripod collar, which is the very one designed to go on the Novoflex adapters I have been considering for use on the nex 7, for Nikon f and Canon fd. As Novoflex apparently offers collars only for nex adapters, this fact seems to echo your thoughts about the relevancy to the strength of the nex mount, of Sony's offering tripod mounts for both of their nex adapters to A-mount lenses. Of course, with any collar, there is always the issue of lens weight vs solidity of collar. If at any point extra strength is needed, a special plate could probably be contrived which utilizes an attachment point at the collar and at the camera, similar in principle to the one by Kirk that was used with the Nikon pn-11 spacer for the Nikon ais 300 4.5 edif. If all goes well in the next few months, I will post any results that come about.

Regards
Clyde

I am truly impressed with the product and what Michael mentioned a while back, about the convergence of stills/video in a product, has now appeared with no discernible weakness.  I was not too impressed with the older NEX5 (even the video being 1080i) and sold off my NEX5 and the 2 kit lenses, a couple of months after purchase - the interface and the lack of a viewfinder being the culprits.  

Technically, the video in the Nex-5 is 1080p30... stored in a 1080i wrapper.  Since a lot of people want 24p video, this is at least not far from that. The problem was lack of control over some of the settings during video (particularly to control shutter speed).  In a later firmware update, you could at least control the aperture.

Quote
The only weaknesses that I see in the NEX7, are the lack of in-body stabilization (one of the really small Olympus models has it, and thus body size should not be the limitation), lack of a fully swiveling screen (the tilt screen does not satisfy me fully) like the Canon 60D, and also the exclusion of GPS from the product.  The exclusion of GPS is a bad move, especially since even low-end p&s products from Sony come with GPS.  The A77 and the A65 also come with GPS.  The HX100V also comes with GPS and surprising that they skipped GPS in a higher-end product like the NEX7.

GPS would be a nice feature, as would IBIS.  Some say that using in-lens stabilization is better for video.

Although, if I have to geotag my photos, I can probably use an iPhone/Geosetter combination.  Although the one time I tried this, it was really off.

I'd like to ask about the manual focusing on the NEX-7.  Particularly, I'd like a comparison with manual focusing on the Panasonic GH-2.  On the Panasonic, when I am in manual focusing mode, as soon as I touch the focusing ring, the image in the viewfinder/LCD screen is immediately magnified, making focusing rather easy, and (especially important on macro shots) allowing me to put the focus exactly where I want it.  So maybe Michael R. could respond based on the trial run in San Diego, or perhaps the answer is the same as for the existing Nex cameras and a current Nex user could describe it.  The comment in the review about increased contrast in the viewfinder didn't help me understand what's going on.  Is there any magnification of the portion of the image you want to optimize?  I've been very much enjoying my GH-2 as a camera I have with me almost everywhere, but a smaller body/lens with significantly higher image quality and at least comparable viewfinder quality would warrant a draw on the bank account.  --Barbara

Barbara,

see this Youtube video for how the "focus peaking" works on the Sony NEX:
http://www.youtube.com/watch?v=q44dIt_gSK4

As you can see, this feature does NOT need you to focus into the image for focussing. But it only works in areas of the image where high contrast detail is present. Anyway, of course you can also zoom into the image to focus. I can't tell you if it switches on automatically whenever you touch the focus ring as I, so far, don't have any autofocus lenses for the NEX. With manual lenses, you just press a button on the rear of the camera to switch to 7x and 14x magnification.

Thomas, thanks for the answer and thanks for the link.  I was surprised to see the SX-70 -- I still have mine.  I was also surprised to see the Korean!  Good thing the visuals were enough!  Thanks again.  --Barbara

Hi,

On the A55 when you press the button a small marker is shown. That marker can be moved around. Pressing the button again magnifies 7.5 times and pressing it again goes 15X. I'd presume NEX-7 will be similar. It works well, but is quite slow.

Best regards
Erik

I have never used an electronic viewfinder. Can you see the effect of a polarizer, or grad ND filters in the finder?

I too am intrigued by Sony's latest. But I approached it from a different direction.

Am going with an A77 body first. Weather-sealed, in-camera stabilization and Zeiss-ready make it very attractive. Sort of wavered between the 65 and 77, but the 77 isn't really much larger and seems more robust. If the system does as well as they claim, I'll get a NEX-7 (or 9) as a second body. Right now their pancake offerings are not attractive to me, and the good looking zooms in their line appear as though they might make the 7 imbalanced and certainly pocketable only in a baggy pocket.

But hey, as long as it's fun...

This is correct, and needs to be emphasized as a cautionary note to those using focus peaking.  Under certain situations, like if your image has any areas that are naturally high in contrast, focus peaking can be fooled by these areas of high contrast.  There is an edge detection algorithm in the software, and that's what you are seeing when you get the highlights on the EVF.  I have found in a few limited situations, that I get an image that is not totally sharp (in focus) due to a scene that is naturally high in contrast.  It doesn't happen very often, but it does happen.

New full size samples are available here, showing the NEX-7 with all kinds of different NEX lenses:

http://www.flickr.com/photos/sportsphotorob/with/6231485889/

To be honest, I am beginning to feel a bit underwhelmed by what I see. I don't really care about all those zoom lenses, but even the images with the Zeiss 24/1.8 at f/2.8 are showing several unsharp areas, and generally the detail rendition is way too smudgy everywhere. For this kind of performance, one would really not need a 24 megapixel body.

Or are these all still issues with preproduction firmware, incorrect JPG settings or the like?

Related, the Zeiss 24mm f/1.8 is being reported by Sony (.ca) as having a delayed ship date - now January 13, 2012, set back from December. I don't know if that affects folks who ordered much earlier (stock related) or has to do with production delays, affecting all.

I've been using my new NEX 5N and EVF for about a month now with a ZM 35/2.8 and CV 75/2.5. I have never had such a high percentage of in focus shots as with the NEX. I would say that manual focusing with my D300 (and Katz Eye split prism screen) and comparable lenses ( I have a ZF 35/2 and CV 75/2.5 SL I) I achieve critical focus on about 70-80% of my shots. With the NEX, I am above 90%, possibly 95%.

I use focus peaking at normal view for a rough cut and then zoom in 5x or 10x to complete focus. I typically stop the aperture down to my shooting aperture before I focus because I find it quicker and there is less camera movement after I focus.

So, I agree. Focus peaking is not a 100% solution, but focus peaking plus magnified view is at least a 95% solution for me.

I have preordered the NEX 7. I also have a A900 and numerous A mount lenses. I note there are two adapters: the LA-EA1, and LA-EA2. I do not intend to use the camera for video, so is there any advantage to the more expensive LA-EA2?
Thanks in advance

The more expensive adapter has AF with Alha AF lenses using SLT technology.

Thanks Erik. Does the older adapter allow auto focus with Alpha & Minolta AF lenses as well (albeit maybe slower?)

The EA1 allows autofocus using the NEX camera's contrast detection. It's slow with A mount lenses because they weren't designed for it.

The EA2 uses the complete phase detection autofocus system as found in the A65 and A77 cameras, and is very fast. SSM lenses are the fastest, SAM next, and older screww thread the slowest - though still now worse than on an Alpha camera.

I have the new EA2 and am using it on a NEX-5n, and will be reporting on it here soon.
