I got one as a second body as also in my case i am having often a very good use for the highest possible MP count for the subject and conditions i am shooting (while my opinion is that good quality 6mp are absolutely enough for general photography). The only thing that made me speculating was buffer performance as my main interest is aviation.
Nikon D3200 Continuous shooting
The D3200 has extended the continuous shooting capabilities of its predecessor from 3fps to 4fps. The drive mode selection lever has been replaced with a more conventional button on the rear panel which activates a menu with the continuous shooting mode alongside self timer and remote options. There's only one 4fps mode with focus locked on the first frame but exposure metered between shots.
To test the D3200's continuous shooting I fitted it with a freshly formatted Sandisk Extreme Pro UHS-1 card. With the D3200 set to Large Fine JPEG mode, I fired-off 100 frames in exactly 25 seconds with no sign of the camera slowing - this corresponds to a rate of exactly 4fps. Set to RAW, I managed 14 frames in 3.4 seconds before the camera stalled, which corresponds to 4.1fps. Finally in RAW + Fine JPEG I fired-off 9 frames in just over two seconds, again corresponding to a fraction over 4fps. In each case I shot at 100 ISO and the buffer took around 12 seconds to completely clear. Swapping the UHS-1 card for a Sandisk Extreme card with a speed class 10 rating made no difference to the buffer write times, so although you can use UHS-1 cards in the D3200, there's no speed advantage to be gained.
Î—mmmm .... The tests i did, with a Samsung Class 10 SDHC (which i think though has a write speed of 13mb/s) with Auto-ISO, Noise Reduction, Distortion Correction, D-lighting, all OFF, gave me these frame numbers before the camera halted shooting untill the buffer was empty :
NEF : 8
JPG Large Fine : 14
JPG Large Normal : 19
Which numbers showed on viewfinder and are indeed aligned with my test shooting and they are far from both the nikon manual and the Camera Labs review. Even if i supposedly used a SanDisk Extreme Class 10 which has a ~30Mb/s , that would probably only speed up the buffer emptying process , it wouldn't affect the number of frames stored in buffer before the camera stops shooting or i am getting it wrong? What factors define the [r] number in viewfinder ? (number of frames stored in buffer), is the card speed amongst them ? (can the camera know the card write speed and include it in its calculations?)
Even in the case that card write speed affects buffer capacity, in this case with the buffer performance i got the increase for JPG FINE LARGE would be from 19 to around 60 maximum and not 100 as stated from Camera Labs and Nikon manual ?
Also in no case i was able to shoot continuously for 25 seconds as Camera Labs stated. Even with JPG Normal Medium
What am i missing here?
