We're under attack!!!!! Sony NEX-7, A77, A65, NEX5N

Just got my 5N, before stocks run short after the floods.

One thing I have noticed is that the camera undercranks. If you set the shutter speed to a low value the frame rate also drops. I haven't done exact science tests but it looks like 1/4 sec drops the frame rate to 4P etc

yes that happens in all cameras.
 
I shot a film at Occupy Sydney with the NEX-5N last weekend. I'll post it on vimeo in the next couple of days. Surprisingly it didn't overheat while shooting for over an hour on a warm sunny day. I stuck my z-finder over the LCD with some gaffer tape and mounted the 5N to my shoulder rig. I'm really pleased with the results. I'll post all the details once I upload the clip.

How can this be even possible?? I don't understand... Most fascinating! Any explanation of this phenomenon??
 
Ok
I analysed some clip shot at 1/4 sec shutter speed. On the timeline I see six frames the same followed by six the same but 1/4 sec later ( 6 frames) and so on.

It appears that the frame rate is set to the shutter speed when you go below 1/25 sec.
 
It seems that something really strange is going on... I can't find other explanation other than there is somekind of a time machine inside of Sony 5N and it somehow bends time (but not space - obviously). But that is very unlikely, because battery is too weak for something like that.

It seems understandable. The way I see it, it shouldn't be able to resolve all the frames if the "shutter" (electronic in this case) doesn't open enough times to correspond to the required frame rate. I could be wrong, just a thought...
 
with film, you just can't make your shutter speed slower than your frame rate: all the time the shutter can be open is the time you're spending on that frame, before going on to the next one; on digital, in principle it could be possible to have a 360º shutter and blend signals from different frames to have an even longer shutter speed... but it seems the 5N is not able to do that; not a great deal though: motion blur would be quite nasty anyway

I'm still really pissed about the Sony NEX sound click issue but in retrospect, it is probably not as big a deal as I thought it would be. I was shooting a student project today with the new Canon XA10. Link: http://www.bhphotovideo.com/bnh/controller/home?O=&sku=749467&Q=&is=REG&A=details

My school just bought fifteen of these cameras at $2000 a pop for the TV station and I noticed that the camera had a clicking noise which sounded very close to the sound described on the NEX. The sound was like a little bb rattling around inside the body put it was isolated, as if the bb was inside a little box which allowed it to move around ever so slightly. Rotating the camera left and right, up and down and dutch rolls produced an audible click to my ear. When I listened to the audio from the onboard mic, it was EXACTLY like the click sound in the NEX videos. I went up to the equipment room and looked at the other bodies and they all had the click, all fifteen of them. This was not the image stabilization because that produced a separate clunk sound which only happened if the camera was tilted forward or backward.

How many cameras have this problem? I don't think anyone cares about the Canon click because it has 2 XLR inputs and we use shotguns and lavs for our recording so I never shows up in the audio.

Now the NEX click could be way louder to the ear than on the Canon but if it is the same, there won't be any issues if you are using an external recorder with lavs and boom mics. I think I will still move ahead with the NEX. I always use monopods, tripods and shoulder mounts so I don't think it will really be an issue and I already decided to pick up a zoom recorder so I think I will be fine until the next hot mirrorless cam comes along.

Looks as though Sony are doing something about the problem

looks like the movie mode in the DSLRs is not really well thought out: hitting the "record video" button in any mode except video makes it record with auto exposure, and AF only works if you use auto exposure too: http://www.dpreview.com/reviews/sonyslta77/page22.asp - bummer - unless image quality itself is a lot better than on the canons, I'd go for the 5N which is cheap and has image quality on par with the canons at low ISO, and much better at ISO 3200
 
I just discovered that Auto ISO is not selectable in manual M mode --- UNLESS --- you fit the flash and have it in the popped-up position before you hit the record button, then you have manual mode with "auto iso".

This can be very useful in certain situations eg stabilizer/steadicam etc



Forgot to add that you can set a bias to this "auto iso" by setting the flash compensation +/- 2 ev, so for example +2 pumps up the exposure.

Also the speed of "auto iso" response is governed by the metering mode, so for example spot metering is fast "auto iso" etc

Shot this in less than 3min. Just some low light footy from the Sony NEX 5N.
Cheap CCTV 35mm F1.7
Shutter 1/50
ISO3200

Color corrected in Magic Bullet (lightly)
No noise reduction

Enjoy!

 
Nice work HHL. You pre-order your Scarlet yet?

I'm DPing a web-series and was originally going to shoot it on the 5D until I discovered right before the first shot that the mirror in my camera broke. Luckily I had my NEX-5N with me for some slow motion stuff, and I ended up using it for the whole thing. The director is in love with the footage and I'm pretty happy with it myself. I'll post some footage at some point.

Glad to hear you got to shoot with the NEX5N and the director loves the image. I love it too....amazing how many GREAT options we have right now.

As for my Scarlet, selling some gear off as we speak. I'm hoping to make the Dec. 31 deadline, but if not, ....no biggie, its only a matter of time. (Having to wait a couple of months won't kill me) ...and as much as we'd all like to think that Sony, Canon, and Panny are "hot on Red's heels"...I think that's wishful thinking. I'll bet it will be another 3 years before one of them has RAW in a camera at this price range. RAW is the reason I'm in.....4K (or greater than 1080)....that's fine, but RAW is the deal for me.

The NEX5N is a wicked little cam....you bet I'm in love. I can't believe the photos and vids that this thing is capable of. And for the clothes I wear, it is pocketable, no problem at all. Cheers Cory!
 
A music video I shot with the NEX-5N and Leica glass. Graded in Magic Bullet Looks. 60p 1080p conformed to 24p

Good stuff! Too bad the VG20 (the just released camcorder w/ the same sensor) was intentionally crippled by Sony - it lacks the color presets and ability to reduce sharpening that the 5n has...

Which is really strange, 'cause the VG20 cost 3x's as much. Worse, Sony is still advertising the features as being on the VG20.

Still, nice work with the 5n - it's certainly an interesting camera.
