AF Speed - Tamron SP AF17-50mm F/2.8

[joecess08]

guyz, would you like to tell, why my 7D with lens tamron 17-50mm 2,8.

sometime cant capture the picture?

it is because of what ?



[ptys007]

@joecess08 How does it fail? Does it not focus and you can't take the picture? Or does it take a picture but there is something wrong with it?

[DrumManiak11111]

Do you knoq if it has a built in motor or was that the cameras because is seemed really quiet?

[ptys007]

@DrumManiak11111 It does have a built in motor. Canons don't have a motor in the body.

[iPhoneNinja14]

Please can yyou tell me what setting did you use shuter and f point

[ptys007]

@iPhoneNinja14 I don't remember! But the fstop wouldn't have made a difference in the view finder. Whatever the setting, it's always wide open between snaps.

[LaczupakabraPL]

[chumacprachu]

thaks for this video !! im buying VC version

[flo1970]

I think I'll buy it! Good work :D

[acousticwie]

Hey man this is very useful. I'm planning to get one. Thank you.

[ptys007]

glad I could help

[prmass1]

When it comes down to is are you willing to hear the noise when focusing.

[MonsterHorrorBoy]

watching this video I see that this focuses as fast if not a little faster than my 28-135mm USM. Like i stated in my other post this would be awesome with VC.

[navymmw]

how do you like this lens? Does it perfom well in low light? Im looking into buying a new lense mainly for aviation photography.

[ptys007]

I like it. I think this is the best option for canon crop cameras. 17-55IS may be better in some respects but

- it's much more expensive

- much larger, heavier and longer (can't use built-in flash on wide end)

- flares and ghosts more (shooting towards light sources). Tamron is very good in this dept.

The lens is sharp from f2.8 on the wide end. On my copy image quality starts to deteriorate towards the longer end (35-50mm) but it's till acceptable in my opinion.

I would buy it again.

[JereHakala]

Cute sound.

[roxynmusicto]

yes this is really a fast focusing lens.

[HiAdrian]

Very useful, will likely be my next lens. Thanks!

Does every Canon mount version have a built-in motor?

[ptys007]

I believe all the EF-mount lenses have motors in them. Canon doesn't have a motor in the camera body like some other mounts, so there is no other way for AF.

[Giardintek]

My Sigma 17-70 sounds about the same, No biggie.

[mixmaxdix]

is that a canon 40d?

[ptys007]

Canon XTI

[jacobnyborg]

Isn't it faster at autofocusing, than the ones in the other 17-50 videos in here?

[ptys007]

The other video I posted here shows the same lens. I don't know how fast AF is for this lens in other mounts, esp. without a built-in motor.

[IonVersion]

i guess this one isnt with built-in motor(a16n2)for nikon ?

[ptys007]

This is the canon version (with built-in motor).

[niburu2012]

The Nikon version with build in AF motor is much slower than this one!!

[CaesarRex]

My Nikon-mount Tamron 17-50 is just as fast as this vid.
