    Upgrading to the NX1 from Canon, ideas?

    In: Cameras

    Posted

    ​As I said, I'm personally using the Sigma 10-20 on a dumb adapter. It focuses manually fine.  

    I also have a Canon EF 24-70mm f/2.8L USM.  I've had the 50 mm - F/1.8 - Canon EF.  The 50 mm - F/1.4 - Canon EF.  The 40 mm - F/2.8 - Canon EF.  As well as a Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM Zoom Lens for Canon EOS Digital SLR Cameras.

    Never had an issue grabbing manual focus with any of that.  It's not as elegant as mechanical, but it can be done.  You can't rig some of 'em up with a focus rig, but ultimately you can focus.   

    If you're shooting video should you really use auto focusing anyway?  My opinion is that you should not. ...and with a wide 10mm focal length @f4.5, it really shouldn't be a trouble.

    And again, my posts on this thread have been qualified from the perspective of using glass for cinema/video, which is what the OP was asking about.

    He already has a piece of wide angle glass, why consider buying another one?  This is not a snarky question.  I really am interested in his opinion of why he wants to do so.

     

    Well I'm not interested in autofocus... if I can control aperture manually from the adapter then no... I don't need to buy a new lens since I only care about manual focus and  aperture! I thought that on digital lenses you're stuck at full aperture.

     Also will ef-s lenses cover the entire NX1 frame?

    ​Lovely and 10mm aren't two things I'd put in the same sentence, but that's just me.  FWIW, I have a Sigma 10-20mm I mount on my s35 sensor-sized cams all the time.  Works fine.  

    And I'm confused.  

    In your post you say you already have a 10-18mm, so what would you be unable to match?  You already have the lens and can keep using it.  My understanding is that the NX1 and the t2i are essentially the same sized sensor...

    ​Yeah but I can't use the Canon EF-S lens (10-18mm) on the NX1!

    Thanks guys.
    that's what I thought... I wasn't aware of any EF-S adapter, that's why I asked about buying new lenses. It really saddens me leaving the 10mm look, also even If I used it on the Samsung with no aperture control (not a funny way to shoot videos) will the EF-S lens cover all the sensor size on the NX1?

    Even the 12-24mm is not as wide :(

    Hello,

    I'm an old Canon 550D/T2i and now I'm sick of its old image quality, fake HD etc.

    I need to upgrade to a new camera also an investment and I was thinking about the NX1, do you think will I regret it? What are the main cons I could experience with this camera coming from the Canon world? What worries me is lenses quality and cinematic look overall.
    The lenses I use right now with the 550d are the 18-55mm (kit lens), 10-18mm, Nikkor 35mm and various 50mm primes (which I rarely use for video). I would need to have at least this range covered, so I was thinking of getting the body only with 18-55mm (the 16-50 is pretty amazing but I can't afford it right now :( ) and still use the Nikkor 35mm with an adapter.
    Problem is: I'm really loving the wide shots I get with the 10-18mm on the Canon, how do I get the same look of the NX1 without getting a fish lens and spending a fortune? The Canon 10-18mm was pretty cheap! Also Samsung in Italy is currently running a promotion where you can get a free 16mm 2.4 or 30mm f2 or 45mm 1.8 or 50-200mm with the body so I don't know if I can temporarily use the 16mm as a wide lens until I find a good substitute..
    Do you think the 18-55mm is any good for video, or at least on par the Canon counterpart? 

    Thanks for any advice :)

    Hi,

    is there a way to use EF-S lenses on the NX1 and control the aperture? Also how does it work for the focal distance, what lenses cannot be mounted on the NX1 also due to the covering area?

    Big news - Samsung NX1 with 4K, 24p and **H.265 HVEC codec**

    What happened to this camera? No samples, no reviews, no production camera tests...nothing!

     

    update: well the pictures are starting to appear. I still see that weird digital overcompressed look at high ISO, doesn't this look awful coming from DSRL sensor of that power? https://s3.amazonaws.com/masters.galleries.dpreview.com/3067188.jpg?X-Amz-Expires=3600&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAIWXD4UV3FXMIDQLQ/20141112/us-east-1/s3/aws4_request&X-Amz-Date=20141112T210321Z&X-Amz-SignedHeaders=host&X-Amz-Signature=af8011a01c58ad3753a07d0e78ee8dc8d0c3c9a5f51cc5d1a51216e3a1567fb3

    Samsung must be doing some weird processing.

     

    Even this at ISO400 looks pretty messed up https://s3.amazonaws.com/masters.galleries.dpreview.com/3067175.jpg?X-Amz-Expires=3600&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAIWXD4UV3FXMIDQLQ/20141112/us-east-1/s3/aws4_request&X-Amz-Date=20141112T210503Z&X-Amz-SignedHeaders=host&X-Amz-Signature=bc5984b3c3e1a32463b1f0deec2120cc334d025e43e1e01f00fc8c776e586e8c

     

    How would this translate to the video part? Mhmm

    I find the 28 megapixel readout at 240 fps a bit hard to believe. Imagine the ammount of raw data this would give. A lot of processing power would be needed to compress this to a usable format. The image processor would be unbelievably overcapacitated if actually possible. Why would Samsung use an expensive powerfull chip like that when not using it? It's just a marketing manager saying it, wouldn't believe it so easily.

    Compare it to Canon raw, 1080p (2 megapixels) @ 24 fps is something like 100MB/s. 28 MP is 14 times the data = 1400MB/s, times ten (240fps) = almost 14GB/second. What kind of supercomputer is going to compress this real time into a codec?

    Maybe the chip can do it in theory, but the whole processing chain in the actual camera? Find it hard to believe.

     

    Maybe they just mean they could successfully record that to the RAM but of course nothing would be able to store it. Just what the system is capable of. Now I just raw footage from the camera.
