The Nikon D7200

Is the D7200 good enough?

The Nikon D7200 is now a ten year old camera, is it still good enough for aviation photography? In my opinion it definately is and it offers quite a few surprises, especially when it comes to taking aircraft photographs. If you don’t want to go for the latest D7500 or the upscalled D500, the D7200 is a reasonably priced option on the scond user or refurbished market. You can buy a D7200 kit with an 18-140mm lense fully renewed on Amazon for a reasonable price.

The image quality is excellent, as is the auto focus. And with a battery life of over 1100 shots, there’s enough capacity for a full days shooting at an air show. The camera is no slouch, running at a full 6 frames per second. The camera can shoot in NEF or JPG, if your shooting JPG – the buffer can handle 100 shots or 16 seconds of continuos shooting.

There are a couple of other nice features, the additional 1.3 crop mode can effectively double the focal lenth of your lense. And the in built flash is great for inside shots, for a nearly 10 year old camera the ISO performance is outstanding. The image below was taken using the 1.3 crop mode, it was taken from the same location as the header photograph using a standard Nikkor 18-200mm lense. Both images at the same focal lenth, exposure, apature and ISO settings – it wasn’t a great day and my photographic skills leave somethong to be desired.

Anyway, I’d say that the Nikon D7200 is a more than capable camera for aviation photography – it is certainly in my bag.

 

I’d say that the Nikon D7200 is more than adequate for most photography needs, with it’s 6 frames a second, large buffer and the additional 1.3 crop factore I think that it is great. It is in my bag and it will remain there for the forseeable future.

It does take some time and effort to create these downloads, also there are a number of costs associated with running the site. So if you can consider supporting this site with a donation it would be helpful, if you find the site useful then why not treat me to a doughnut – or even a doughnut and a coffee if you’re feeling really flush.

Or if you are thinking of ordering something from Amazon then you could click the link to get there, it doesn’t actually cost you anything. And it will help me to pay for the site hosting, which is getting more expensive like everything else.

But regardless of whether you donate or not, I hope that the contents of the files are of some use, also bear in mind that the files are as dated in the bar graph on the down load page – I will try and produce a new data set every month or more frequently if time allows.

The Crop Factor

What is the Crop Factor?

The crop factor is effectively a focal length multiplier, but that isn’t as described. It basically relates to the ratio of the diagonals of the sensors within the camera, the standard full frame sensor is the same size as 35mm film. With most other sensors being smaller by what we term the crop factor, using Nikon as an example. \the diagonal of the crop sensor DX format, will fit into the diagonal of the FX sensor 1.5 times.

There is an excellent description here with some very good image examples. It is worth checking out this page, to gain a better understanding. If you would like to check out your camera and lense combination, there are a number of crop factor calculator sites.

What does it mean to the photographer, well in ordinary terms not that much. Pretty much what you see through the viewfinder is what you get. Where it becomes problematic is when you use cfop format lenses on full frame camera’s, as the image can be dark at the corners.

What are the benefits?

In essence the 1.5 crop factor a Nikon camera is applied to the focal lenth of the lense, making a 200mm lense apear to be a 300mm lense. This is due to the camera discarding a larger portion of the image, when compared in area of the DX sensor is less than half that of the FX sensor. This provides what is effectively an increas in focal lenth, it is also worth noting the crop sensor cameras and lenses are less costly than full frame cameras.

What are the drawbacks?

For a given resolution say 24Mp, the photo sites on the sensor are much smaller. Which means it is generally less sensitive to light and less tolerant of movement, although with image stabilisation this is not so much of a problem in modern cameras. The differenced between the capabilities of DX and FX formats, has over the years narrowed. Both formats are capable of producing outstanding images in the right hand.

A recommendation!

Im not in a position to say buy one or the other, I use both formats in my Nikon DSLR’s. I would however say, that the DX format cameras have done the job equally as well as the FX format cameras. I would suggest that buying a camera like these is a big ticket item, do your homework before parting with the cash. Also, there are a number of photographic companies that hire cameras in both formats. It is worth hiring the equipment to test, although with the more advanced models there can be a steep learning curve.

Surprising Development

Unexpected Development.

I have decided to update the Plane Spotting Guide, it has come as a surprise to see that this was the most popular download of the last three months. The original guide was quite terse, with just a few pointers – I’ve enlarged it. Adding a few more sections and quite a few links that I hope will be useful.

 The whole guide has been updated, hopefully it will be of some use in its revised form.

Register Downloads – 24/10/2024

So no sooner had I updated the last set of files and the Australian data set was updated, that is released again by the Austalian Government Civil Aviation Safety Authority. That is why there has been a slight delay in publishing them, as usual there have been more records added by all the respective authorities.

The total record count now sits at 732,954 records, quite a number. I’m sure that there will be another update soon, so keep watching the blog. I’ll be following with an update of the spotting guide, as surprisingly it has proved to be the most popular download and to be truthful I’m not sure why.

The updated files are;

  • The Australian Civil Aircraft Register
  • The Canadian Civil Aircraft Register
  • The Current United States Civil Aircraft Register
  • The De-Registered United States Civil Aircraft Register

There should be a November update soon, as usual this depends on the Australians. A final thought is that I’d like to possibly convert these to a Portable Document Format (PDF), these can be opened with adobe. It is however a little bit more work, as such I’m considering making these downloads available to only people registered with the site – any feed back would be welcome.

Keeping this site running.

Site Costs

Although not a massive expense, keeping this site running does cost a bit. I’ve had the occassional donation – but they are occassional and I drink a lot of coffee along with eating the odd dohnut. So as an additional cost covering stream I’ve started an Amazon Associate account, just to try and defray the costs for the site a bit more. This means that there will be Amazon links in some posts, there will also be reviews of any spotting related products that I buy.

 The site used to carry links to aviation stuff on Amazon, usually books that I thought would be suitable for people interested in aircraft and their histories. So the site will not look that different, but if you are thinking of buying something from Amazon – coming here and clicking through on a link would help – it also doesn’t cost you any more for the product.

What does it mean for the site, well it should hopefully mean that I will be less out of pocket than I am. And I may be able to find more interesting things to post about, anyway that is the gist of it.

How can I identify a PIA aircraft?

Well this is a bit of a conundrum, you see a plane look it up on one of the tracking sites and all there is is a ICAO code and a call sign. Everything else, registration, type, origin, destination and many other spotter friendly features are not displayed.

How then do you find out the actual identity of the aircraft and whatever other information that you like to collect?

Well the truth is you won’t get the information without some effort, it’s unlikely that you’ll find out the information without the help of other spotters. The only certain way of identifying these aircraft is a physical sighting, at either end of the flight – so if you can’t be at the airport when it lands then other spotter groups would probably be the place to start.

Typically a week day view of US air space will show thousands of aircraft, and the vast majority of these are readily identifiable using applications or web sites like flightradar24 or in this case globe.adsbexchange.com.

So in most cases looking up and seeing an aircraft, will if you know where you are – make the identification fairly straight forward, a quick look at the app or website and you have everything you need.

In the begining tracking flights was more technical, there were tools like ACARS – but you needed certain technical skills to use that to track aircraft. But along came flightradar24, this was an absolute boon to the spotters.

Lack of privacy was seen to be a problem, so along came the FAA’s LADD (Limiting Aircraft Data Displayed) – which is a filter that the FAA puts in place for anyone taking a data feed from them – the image is LADD subscribed aircraft.

Just to be clear, these three screen shots were taken within a few minutes of each other the bottom shot is filtered by PIA subscribed aircraft.

As you can see, there aren’t that many aircraft in the view. But what I can say is that there is literally no information that would interest a spotter, the navigational information is there but little else is available.

In the next post I’ll go over the options and list some of the ways that you can try and find out the aircraft identity. But in the mean time consider this, both the LADD and the PIA services are free – so it’s likely that people using the LADD service will move to the PIA service.
