Is 70-210 Lens Enough?

Wed May 31, 2006 2:50 am

I'm a starter in spotting, and I'm planning to buy a digital SLR camera. Since I have an old analogic Nikon camera at home an lenses for it, I decided to buy the Nikon D50, instead of Canon EOS 350D or Nikon D70s (D50 is cheaper  Wink), supposing the lenses fit in the new one (I still have to check that, but that's not the point). The thing is that the lens I have at home is a Nikkor AF 70-210. But as far as I have seen, most of the people uses lenses of 300-400 mm(?) focal length. If what I need is bigger lenses, shouldn't I rethink my purchase? Because if I have to buy a 300 mm lens, maybe it's better to buy one for a Canon, since in the (distant) future I may switch to the Canon EOS 30D (it's widely used by people here, isn't it?). So, is 70-210 lens enough for spotting? Thanks for your help!  Smile

Only you can answer that! It all depends on how close you are to the aircraft.

Well, my main place for spotting will be MAD. I've been only once spotting there, and in only one place, but I guess planes will be passing at about 500-1000 metres from me. Maybe less in some cases.

Nikkor AF 70-210.

Keta,

I think I read a very positive review about that lens.
If it's long enough really depends on the airport.
Maybe you should have a look at photos from MAD on the site, and contact the photographers.

If this is the lens I am thinking of then no reason it shouldn't work on a D50 and like Peter mentioned it gets good reviews. I started off with a D70 and a 70-200mm lens and it's been a great combo.

Roughly

A 210 mm lens has a picture angle of around 11 deg, so half angle of 5.5deg.

To fill the frame at that angle an object at 500m will need to be

2*(500*tan(5.5) ) m long, so around 100m long (96.25m)

B747 is 70m long, so in rough terms you'll only be filling 2/3 of the frame with a B747.

At 1000m you'll only fill 1/3 of the frame with a B747.

So, with a 210mm lens I'd get closer to the action.

Or go for a 300/400mm.

The problem with a longer lens in MAD, especially in the summer, is likely to be heat distortion and haze.

A Sigma 70 - 300 f4 - 5.6 telephoto zoom costs about £115 (160 euros) in the UK. I have one and am very pleased with it. It will give you just that little bit more flexibility.

Given that we are taxed to hell and beyond  Angry I'm sure you could get a better price.

All depends upon the airport, but IMHO it's one of the best quality zooms on the market. I love my Canon 70-200, and the Nikkor model is awesome!
Respected users.... If my replies are useful, then by all means...

Do get a real dramatic shot 200mm is a little on the short end but you still have some MP to play around with (cropping the image later on) even though this should not be your main technique, rather get closer to the airplane or buy a bigger lens.

I think we are talking about 2 different things here.....you are talking about the f2.8 version and he might use this one: "Nikon AF Nikkor 70-210mm f/4-5.6D"

Quite a different league......
