Last week, Belabor MMA 131 took place at the Valley View Casino Center and I was there as the house photographer. Now, in the past when the Strikeforce MMA fights took place at the venue, I was allowed a cage side shooting position. This time, that did not happen. I had the run of the building, but not close enough to the cage to shoot through the fence so I went up high and shot over the fence.
If I was shooting cage side, I would have used the Nikon D4 and 24-70mm f/2.8 lens but since I was at a much greater distance I went with he D750 and the 70-200mm f/2.8. The reason for this was simple, I was going to have to crop the images a lot and wanted as many pixels as possible. The Nikon D4 is a 16.2 Megapixel camera which creates file that is 4928 x 3280 while the D750 is a 24.3 Megapixel creating a file that is 6016 x 4016. So the D750 just gives me more image to work with when I know I have to crop a lot the image. Why, if everything was equal, I would prefer to just shoot closer of have a longer lens but since neither of those options was available at the time I had top come up with a different plan.
In the past, I would have just continued to shoot using the full frame and then crop later, but due to the distance I was shooting from, every frame was going to have to be cropped. So I set the D750 to use of its crop modes. The D750 can be set to only use part of the sensor, either as a 1.2 crop or a 1.5 crop. All that happened is that the camera only uses the middle part of the sensor. Lets look at the numbers for a minute. When using the 1.5x crop the camera acts as a DX sized sensor and creates a file 3936 x 2624. in the 1.2 crop mode, the camera records a file that is 5008 x 3336 which is actually bigger than the file from the D4.
As you can see here, the area of the image that will be cropped is not needed at all. It’s not difficult to crop the images later but why record a ton of data that is just going to take up place on the card and the hard drives just to be cropped later. As an added bonus, since the files are smaller, the clear out of the buffer faster. It does nothing to the images quality.
The more I shoot the D750, the more I like it.
