10mm-420mm

Ever wondered what the different field of view is between a 10mm ultra-wide lens, and a 420mm lens on a Canon APS-C sized sensor camera is ?

There you go, both shot from the same spot (cliffs above the river at Fortitude Valley). The shot on the right is the Raperian Plaza which can be seen on the left as the tall building with the spire on top to the left side of the city.

    are they both un-cropped images scaled down? 420mm is crazy
  • David de Groot said:
    Sure are. All I did was convert them from RAW in Lightroom, export and combine with DipStych.

    On a 1.6x crop body (like a Canon 400D/30D, etc), 10mm gives you the field of view of a 16mm lens on a film camera, and 420mm gives you 672mm.

    Kick arse lens!
  • David de Groot said:
    I'll say :)
  • ronnietan said:
    but isnt your 10mm lens EF-S or DC mount? which means it will give true 10mm on your 400D, while the tele gives you 672mm
  • David de Groot said:
    EF-S just means the lens can be smaller and cheaper (usually) than EF, but you still need to multiply out by the crop factor. So my 10mm gives 16mm equivalent FoV.

    Great comparison, David.
  • David de Groot said:
    Definitely stands out when you see them side by side like this.

    wow !
  • David de Groot said:
    To be fair, it's two ends of the extreme. 10mm is very wide, and 420mm is well, quite long. Still neat eh ?
  • ronnietan said:
    ah i see, i always thought it gave the true width

    so basically 10mm DC/EF-S on 400D replicates what a 10mm lens would on a 400D. so, what would a 10mm DC lens show on a full frame body? it cant be 10mm because its not showing true 10mm width?
  • David de Groot said:
    A 10mm DC/EF-S lens on a 400d replicates what a 16mm lens on a full-frame body would give you. This if you put a 10mm DC/EF-S lens on a full-frame body, you get 10mm, but due to the way the DC-EF-S image projection works, you'll get massive black vignetting on the edges (like this)

    Yes, I've always wondered that. :p That is an impressive range...like a television camera range (ok, TV camera's probably don't go that wide, but their tele is amazing).

    Thanks for mentioning DipStych - got to be quicker than doing ...tychs in Photoshop!
  • David de Groot said:
    Well a TV camera is all built-in, whereas I used two different lenses. :)

    On Windows, there's little reason to use anything else than DipStych :)
  • KennyWP said:
    Hmmm now that is a big difference! Now all I need to do is see the difference between 10mm and 1200mm for fun :)
  • David de Groot said:
    I'll tell you what, you buy me an EF 1200 lens, and I'll do the comparison for you ;-)
  • KennyWP said:
    Sure right after I buy myself one :P
  • David de Groot said:
    Ah well get to it man ;-)
  • theurbannexus said:
    Haha great diptych. Dramatic difference in what you see with each. Does the 400 hurt to carry?

    I am always drawn to -tychs :)

    That 300/2.8 is so tempting.

    Seems super flexible when you add the 1.4x. And if you're shooting a cropped sensor the extra reach can be handy. For example straight out of the box it's 480/2.8 on a 1.6 crop! Which means it would be cheaper to buy a cropped body, full frame body and a 300/2.8 than a single full fram body and the 300/2.8 and 400/2.8. Add in a 24-70/2.8 and a 70-200/2.8 and you'd be set for much less $ :)

    I may be posting some 300/2.8 unboxing/uncrating photos sooner than I expect :)
  • David de Groot said:
    Indeed it's a sweeeeet lens. Very very sharp, quite versatile as you've noticed. The only downsides are price and weight.
  • Roving Rob said:
    Need a 50mm shot in between them to show approximately what the human eye sees from that vantage point as well :)
  • David de Groot said:
    Or a 30mm on a crop body... ;-)

    You know what i mean :P
