My Canon lens 75 - 300 mm (not usm) is a bit too noisy...

My Canon lens 75 - 300 mm (not usm) is a bit too noisy. Is it

normal? The engine of the AF makes awful sound

(aaaagggggggggrrrrrrrrhhhhh). If anybody who has the same lens has

the same problem?

 

Merry Christmas, Michael

We have two of these one USM one not USM. The USM is quieter

than the other one and definitely focuses faster. Yours may

have a problem if it is that loud. Go to a photo store and

try one there to see how it sounds. Maybe you never used the

old AFD Canon EOS lenses. Those were loud!

Thanks for answering I just didn't think about going to the shop and trying another lens. (Why didn't I think about it earlier... Maybe becaus of Chistmas:) One more question can I make from normal lens USM? If yes how much doest it cost?

 

Merry Christmas and a happy NEW YEAR - Michael.

<p>You can't modify the non-USM lens to make it USM. You'd have to take it back to the store and see if they would let you exchange it (and pay a bit more, since the USM model costs a bit more).</p>

[rob_murray]

No they cant be modified. The glass is the same in both lenses

only the motor is different. There is a big difference in focus

speed. If you can get the USM model. Or the 100-300 USM model.

I haven't tried the USM version of the 75-300, but I've read many times that it's micro USM, not "real" USM and so the difference is barely noticeable. The 100-300 has "true" USM, but it's more expensive as a result.

[j_smith6]

If I can't change it for USM I'll just see can it be more quiet.

 

Greetings, Michael.

I've owned/used several of these over the years including the first non usm model ,later usm versions and non usm's plus the 100-300 USM lens

<BR>All the 75-300 lenses are rather quiet.The usm versions are kind of like a soft hissing noise,not like a motor sound at all and very easy to not hear .

<BR>The non usm versions are still very quiet but sound slightly motor-like.They certainly couldn't be considered noisy by any means!

<br>I'd say you definitely have a problem with yours

<P>Canon did make noisey lenses but that was back in the days of AFD motors-they sound abit like a dentist drill! ! :)

 

<P>By the way-i must dissagree that the usm versions of the 75-300 lenses are much faster at focussing.I'd guess they focus about 30-40%(?)faster...but the point is that ALL versions of this lens focus too slow for fast action

<BR>Don't get me wrong,these lenses are quite good for a cheapie-i currently have the IS version.But if you need fast focus for sports,etc,buy the excellent 100-300/4.5-5.6 USM.It's <a href="http://members.dodo.net.au/~l8r_ron/index_2.html">abit sharper</a> ,better built and has the genuine ring type usm motor

[j_smith6]

In new year I'll go to canon service and ask about it. I'll try to send on your e-mail the sound of engine. Thank you for writing and giving so good answer.

 

Happy new year, Michael.

I've just tried my 75-300 and I can hear it with a TV at normal listening loudnes in the background, but it is not loud.

A bit more than the 35/2 and on par with a Sigma 28-70 EX.

 

And a lot louder than the 24-85!

[j_smith6]

It was broken, but in canon service I could took it back after one day.
