M100 Posted May 29, 2015 Share Posted May 29, 2015 NX500:+ codec ( but how does it really compare to G7? anyone? )- hdmi output, lensesG7:+ lenses, hdmi- codecLX7:+ lens- hdmi output, no lens changeAll cost about the same.Question: What is the true lens resolution possibility ~ 1000 USD ?1. Is it true that in m4/3 we can't really use practically more than the lens resolution of LX7 and 12Mpx, because there isn't a enough sharp lens ( > 10Mpx ) to use with G7 ( m4/3 or with adapter ) which costs less then 1000USD? 14-140 is only 6P-MPix ( dxomark ) and 14-42 is 7P-MPix. 2. Maybe the NX500 has a 28MPx sensor, but is there any lens configuration to use 15,20 or 25 MPx on NX500?3. Is it true, that when we want to go for a true 25-30Mpx resolution, we have to buy at least D600/700/800 with a good lens?At last ... what do you think about lens res?

Guest Ebrahim Saadawi Posted May 29, 2015 Share Posted May 29, 2015 No such thing as lens absolute resolution. And a tiny 1" size sensor and a 1" lens can be higher resolving that a FF sensor and a FF lens. It's not relevant to sensor size, just the resolving power of the sensor, and the resolving power of the lens. Quote Link to comment Share on other sites More sharing options...

M100 Posted May 30, 2015 Author Share Posted May 30, 2015 M100, first say what your needs are. 1. Achieve the highest possible sharpness and image quality, using the camera body <> lens kit2. Find out if the lens sharpness matters - ie. what criteria to consider when choosing a good lens Quote Link to comment Share on other sites More sharing options...

Those DXOmark sharpness ratings are heavily related to the camera megapixel count. For example, Nikon's 50mm f1.8 has a 10mpx rating on the Nikon D7000 (16.2 megapixel) and 14mpx on the D7100 (24 megapixels). So don't use them to judge overall lens qualities for a camera system. In fact I've found my Olympus 17mm f1.8 to be sharper wide open than a lot of other glass I've used for other systems.2. Dunno3. For 1080p video it doesn't matter so much Quote Link to comment Share on other sites More sharing options...
Marco Tecno Posted May 30, 2015 Share Posted May 30, 2015 Considering that the nx 45mm can do 12mp on a 20mp old camera (nx20), I wouldn't be surprised if it could resolve 16+ mp on the 28mp sensor. The 16-50s zoom is very sharp and the 50-150s is as sharp or even sharper. Quote Link to comment Share on other sites More sharing options...
M100 Posted May 31, 2015 Author Share Posted May 31, 2015 Thanks,I've tried to find tests with specifc lens and camera, but they haven't tested it yet - so I've tried similar sensors like GH4 > GX7.We're talking about 4K UHD and thats ~8MPx.Marco, are you talking about the Samsung NX500 kit 16-50?Looking for Samsung 18-200mm f/3.5-6.3 ED OIS Lens test with NX500.

Marco Tecno Posted May 31, 2015 Share Posted May 31, 2015 Nope, I was referring to the expensive S lenses. The pz kit is good, but far from the S. Quote Link to comment Share on other sites More sharing options...
