He once stated;

Tripods are for the weak. I stack the odds in my favor by firing bursts of several shots in the Continuous shutter mode and sorting out the sharpest later

Amongst many other classic quotes and rantings of a madman. He may be entertaining, but for hard facts and unbiased opinions, he is not the man you seek. :)

Its true I think some of the things he says are pure ********.

Is that word allowed?

Well I'm going to get the Nikon 17-55mm, selling my 18-200mm and at a later date get the 70-300mm or even the 80-400mm ;)

Won't that leave a big 50mm focal length gap? The 70-300 is equivalent to 105-450 on a DX camera isn't it?

55-70mm is not much of a gap to worry about.

That range is the dead zone really. Usually you want to be at a wider angle, normal angle, or telephoto rnge

Don't know :p I'm not saying don't do it, just that there'll be a bit of a gap until you get a lens that covers between 55 and 105mm. :)

Its npot 55-105mm Just 55-to 70.

Looking at my statistics from my 18-70 lens I have almost no shots from 55-69mm. 95% of my shots are from 18-35 and 70mm.

But the 70-300 is a full size lens, so on a DX sensor is effectively 105-450. :confused:

Depends what the OP needs really, as with everything.

You do realise that the 1.5 crop factor will apply to all lenses to his 55mm will = fov of 82.5

No :p I'm still trying to get my head round it all!

I thought that all DX lenses are measured for DX cameras, ie the 17-55 is a 17-55 on a DX, but a 28-82.5 lens (roughly) on a full frame, and all non-DX lenses are measured for full frame cameras, ie 70-300 is 70-300 on an FX camera, but 105-450 on a DX camera.

It's all really confusing. :)

Nope. All DSLR lenses are measures in 35mm equivalent. So depending on the make and model of camera you have, multiply the number given by 1.3(Canon 1D), 1.5(Nikon), 1.6 (Canon) or 2(Olympus) to work out the equivalent field of view. The fact that a lens is DX doesn't change anything.

Ahhh, now it all makes sense! Thanks for that Khan, now I can stop trying to work out what the equivalent focal length is referring to!

A 70mm lens is a 70mm lens. DX FX makes no difference to the lens.

I know it's not going to change the lens, but the picture will be more zoomed in on a DX camera. I thought I'd figured it out last night, but I've just seen a review of a 50mm prime and the picture is much more zoomed in on the DX sensor. So confusing... :o

OK, so a DX lens is basically identical to a non DX (FX) lens. The image circle it produces is smaller, so the lens wont work well on a full sized sensor (You get a black circle around the outside).

Therefore on ca DX (crop) sensor, a 50mm on an old 50mm 1.8 prime or a dedicated DX only lens will have an identical magnification. The image produced would be the same (barring optical flaws and minor things that make up image quality).

The difference lies soleyl within the camera's sensor size. Nothing else. The DX crop sensor is like taking the full sized 35mm sensor and cutting away and removing the outside portion. This is equivalent to taking a photo in photoshop and viewing it full screen with it fitting in the window size, a DX crop sensor just takes the middle 2 thirds of that image - so like using the crop tool in photoshop and cutting out the middle image window. Hence why the sensor is called a crop sensor, as for all intents and purposes, you've basically cropped away the rest of the image. If you view the cropped image full screen again in photoshop you seem to have "zoomed in", or magnified the image.


There are some more subtle differences between DX and FX sensor. Such as the equivalent depth of focus, and things like pixel density.

But a DX lens changes nothing.

A 12-24 F4 DX Nikon lens is equivalent to a 18-36mm lens when used on a full sized sensor like a D3.
 
Thanks D.P. I thought that's how it was, but then I saw some pictures and it just confused me more. Sorry to sounds like a complete moron, I only ask so I can get better. :)
 
Well got my new Nikon 17-55mm DX lens today and must say it feels lovely and the focusing is nice and fast. Going out tomorrow for the day to give a proper test.
