Hi guys,

Had my Nikon D3200 for a few months now and slowly getting the hang of it.

I went to an airshow on Sunday and tested some shots with fast shutter speeds, worked out okay but I found the stock lense didn't zoom close enough and I lost details cropping them in light room.

What would be a good zoom lense for a beginner like me? Seen some tamron 300mm ones on Amazon around the £90 mark but as a newbie, I'd prefer to have some experienced advice first.

Many thanks all, I'll post a few snaps tomorrow!!
 
I don't mind spending more, couldn't afford much more than £200 though.

I'll have a look at those two lenses in a sec!
 
another vote for the nikon 70-300 vr. can say what the cheaper ones are like but the 70-300 is a cracking lens for the money.

if you can hold off and save the money go for it.
 
Seems £290 is the cheapest I can find the nikon 70-300 VR.

Looking at the flickr images taken and YouTube reviews I think I'll hold off and save for this lense! Looks mega sharp to :)
 
so it doesnt act as a 105/450 then on a crop camera ? if so iv been getting that wrong for a long time after reading waaay to many forum posts who says it does.

On a FF camera you would need a 105-450mm lens to get the same angle of view, so that part is correct.

However, you seemed to think that because the lens was designed for FF then it had this property but if it was design fro crop it would. A 300mm lens is a 300mm lens whatever the sensor size it is designed for, you will get the same field of view at the same focal lengths.


300mm just means the front element is 300mm from the sensor. It is a physical measurement that doesn't change with the underlying sensor.

Therefore the Nikon 55-300mm DX lens designed for crop sensors gives the same field of view and subject magnification as the 300mm end o fhte 70-300, or 300mm /f2.8 designed for FF sensors.
 
ok i was talking about the zoom so on a crop it would be like a 450mm rather than the 300mm that it is. or have i got that mixed up.

It is like a 300m lens being used on a crop, not a 450mm lens.

Every 300m lens will give you the same image when used on the same camera, irrespective of what sensor size that lens was designed for.

That's correct. I think you and DP are talking about different things. Bottom line, a 70-300mm lens on an APS-C crop sensor (1.6x crop) has the effective focal length as 110-480mm lens would. You'll also see different depth of field at comparative focal lengths depending on whether it's mounted on a full frame or crop sensor.

Actual 50mm on a full frame vs. effective 50mm (30mm lens at 1.6x crop) on APS-C crop will produce different DoF.

Actual 50mm lens on APS-C gives equal fov to an 80mm lens on a full frame.
