"Replacement for my old D300"


Virginia Beach, US
          

I am going to Tanzania in late September and want a lighter faster camera to take. When I got my 18-300 lens B & H suggested I get the D7100 body as it is faster and would be a good move as I still wanted a DX camera not a full frame. What do you think?

I'm not sure what they meant by faster.. but the D7100 is a great option. With its 1.3x crop mode your 18-300 becomes a ~600mm f/5.6 lens. While it won't be the best in sharpness... it will be lighter and more compact!

I would think that is not really the case, to me, crop factor is only applicable to the entire sensor - for instance the 1.5 crop factor of an APS sensor as compared to full frame. For instance - 70-300mm vr on my D600 gives me a crop factor of 1 which is 300mm for 24.5 mpixels. Put it on the the D7100, I get the same mpixels at the 450mm equivalent FOV - it makes sense that I now get equivalent megapixels per sensor size and know I will get as detailed an image.

If we start applying crop factor to actual image crops, whether performed in-camera or post processing, it seems to me that muddies the concept. For instance, I could say I get a crop factor on my D600 of 1.5 if I set it to DX mode and shoot my FX lenses. But in fact, I get a 10.5 mpixel image - I could do better with a D90 or more so with a D7000.

Just a perspective,

David

It was pretty much correct - in a way

Using a 300mm lens on a D7100 in its 1.3x crop mode gives you a 15MP (approx) image with the same field of view that you would get from a 600mm lens on FX.

Indeed, but I think he was saying that he has the option in post processing anyway, so building it into the camera doesn't give him any additional capability. What it does do is shrink the file size and save time, CPU cycles, and storage space if he knows he is going to crop anyway.

Brian,

I get that about the 1.3 crop factor, but to me, it is just marketing speak to sell what is going to be a really good camera anyway.

Just my opinion, but we can do this calculation for any camera, but it is just a calculation that leads to less image resolution than the native sensor size of the given format. So more math - using my D70s at a 1.5 crop factor yields a 2.66MP image at 600mm FX equivalent.

The only real crop factor advantage here is that one gets the same 24.5 mpixel at 1.5 times the FOV with a D7100 over either a D3x or D600. And that is a very real advantage in certain situations.

Again, just my perspective,

David

I intend to try to use the 1.3x crop mode for birds in flight with my 300 f2.8 VR. I most often currently shoot birds in flight with my D300s, 300 f2.8 VR and TC-14E. I will attempt to do this because the 300 f2.8 VR autofocuses faster without a TC. Assuming I use lossless 12 bit, the D7100 frame rate increases from 6 fps to 7 fps in crop mode - but far more importantly the buffer goes from 7 shots to 12 shots. This is still far short of what I'd like - I often fill the buffer of the D300s when shooting birds in flight. Anyway, yes it is the pixel density of the (whole) sensor that suports this capability, but it isn't quite true that it is just marketing.

Jim

Good points Jim, I had not thought of it so much about increasing frame throughput and buffer.

Well, I see it as a useful option (in some circumstances), and not just a marketing gimmick. As Jim points out, using the crop mode makes a difference to the file size, frame rate and buffer depth.

Rest assured that this conversation has been held many times, going back at least to the D2X with its "High-Speed Crop Mode"

Brian,

>the crop mode makes a difference to the file size, frame rate and buffer depth

The only advantage I see, is the ability to have the smaller size files. The issue for me is that the crop box lines, like my D600 has when I use a DX lens, interferes with my multi-decade use of framing within the entire viewfinder of an SLR-like device.

If you go to Tanzania every year or so and you have the possibility to return easily, I might take the D7100 BUT, as with most of new cameras, it might have some "particularities" (like in the d600) that may ruin you chance for a beautiful and unforgettable trip. If you would have to sell the D300 in order to buy a new camera, I believe that the D7000 will give you all you need and all you want in a very trusted body capable of excellent photography. The D7000 is a non issue camera !!!

Otherwise, I would take the D7000 as your everyday use camera and would take the D300 as a solid back up that you already know very well how to use (so the reports say. I don't have it and have never used it.) All the crop arguments are fine and very important IF, and only IF, the d7100 does not fluke your way and sour your trip to Tanzania.

Have a nice and unforgettable trip to such and exotic country.

Carlos
