29TH APR: D7100 First Thoughts
Two months or so back I purchased Nikons D7100 camera, targeted towards the 'enthusiast' photographer I was a little sceptical whether this camera would be up to the job of replacing my Nikon D300s. The camera uses a 23.5mmx15.6mm 24.1 megapixels APS-C sensor with the ability to add another 1.3x crop in camera reducing resolution to 15 megapixels. Well after two months of use its fair to say this little camera is punching well above its weight, since buying the camera I've managed to test it out a couple of times in Wales shooting fast jets in the NWMTA or more commonly known as the Mach Loop and also at some track days I have been covering for MSV and I've been pleasantly surprised.
In fact my D300s hasn't been taken out of the bag since and is now my second camera body, the images from the D7100 are above and beyond those that are from the D300s - not only in terms of resolution and the ability to crop but also the fantastic tonal/dynamic range and sharpness of the images, no doubt down to the lack of an optical low pass filter.
One thing the Nikon D7100 doesn't have going for it is a large buffer, with online tests varying between 5-8 shots depending on memory cards and RAW set-up. Initially this was a little worrying, after a little testing at the race tracks with only a 45mbs write and read Sandisk SD card my worries were cast aside. As long as you aren't a 'spray and pray' kind of photographer this shouldn't even be an issue, up until this date I've only hit the buffer once and that was down to myself machine gunning a Tornado GR4 through Cad.
For me the ultimate test of a camera for my style of shooting and subject is the Mach Loop or LFA7, here you can witness RAF & USAF fast jets operating at 250 feet and between 420-450 knots - a test of both how well the autofocus works, buffer, FPS, exposure and any grain issues from high ISO (although I rarely shoot above ISO 400 if I can help it).
The AF is lighting fast, I haven't yet tried the 3D tracking however as I've essentially set the camera up as my D300s is. As a friend once told me, the more you ask a camera to do the more it slows it down - ie keep it simple. I've found it trying to 'hunt' a couple of times but I've put this down to heat haze and also the bright light on the front of the Hawk T1 which used to confuse my D300s constantly. Initially looking at the images on the back of the camera I wasn't that impressed, they seemed to have a green tint to them but it seems this is more a back screen issue on the D7100 as the WB has been absolutely spot on for the most part apart from some tricky shooting conditions on my first trip to the Loop where the light was incredibly hazy.
Although not a direct replacement for the D300/D300s I couldn't be any happier with the D7100, it is leaps and bounds ahead of the D300 (rightly so) and is so much better than I expected. I really feel the camera has helped to 'up' my photography as I felt I'd reached my limit with the D300s.
I'm really looking forward to giving the camera more of a challenge especially at the air shows this year.
