I just bought a D70 kit a couple of weeks ago and I also just bought a Nikon 50mm1.8. There is quite a bit of difference between the kit lens and the 50mm regarding the sound of the auto-focus. Is this normal or do you think there is something wrong with the lens. I bought it from B&H as new.

Any help will be greatly appreciated.

Thanks in advance,

tho I cant see the dif in the pics. It slams back and forth from close to infinity too if it cant focus lock.
The 50 is not an Af-s like the kit lens.
Af-s means that it has SWM (SILENT Wave Motor) that is a lot faster
and quiter than conventional lenses.

I think that is pretty common for AF lenses to do when they can't focus (because of light or too close). The lens is searching for something in focus and when it can't find it goes back and forth from close to inf. On the other hand hearing you guys call that lens loud has me excited to try out an AF-S lens.
thanks for your quick reply. i'm glad it isn't a defected product
but sad that it is so loud.
 
... in that situation? If there's nothing to focus on theres nothing to focus on. Should it cycle twice and then throw an error message? Thould it just stop in the middle (out of focus) and let you shoot? Then folks would complain about that!

When this happens to me I point at something that it can focus on in the desired depth of field (like the profile of someone's face), lock the focus, recompose, and shoot. In other words, basic photography skills.

Please don't take offense, but Sheesh, the camera and lens can't do everything for you! Am I missing something?

I realize it needs a contrast to focus, just commenting on the noise and slamming action. Does kent need a nap?

...that with Nikon, non-AFS lenses use a mechanical linkage from the focus motor that is built into the body. This motor is louder and with certain lenses can sound even louder with the gearing.

Kent,

I'm very new to SLR cameras and I was simply observing the performance of the D70 kit lens with the 50mm 1.8. A couple of things I noticed between the two lenses are:

1. The 50mm is a lot louder than the kit lens. I've never purchased any lenses before except for the kit lens on the D70. I have learned now that this is probably normal and the kit lens was made to operate with less noise (AF-S).

2. I have noticed that the focusing on the 50mm is slower to focus then the kit lens. As Kurt Meyer best described in his previous thread ... searching for something in focus and when it can't find it goes back and forth from close to inf. This happens when I'm focusing on a face or when I'm focusing on an a person 4 feet away.

Anyway, I was just curious if this is normal for the lens compared to the kit lens. I think it is normal based on some of the comments and realizing that the kit lens was just recently developed and the 50mm has been around for ages.

Regards,

If you point the kit lens at a white wall, it will also go to infinity and back (or beyond...:).

See my post below about the noise and speed.

Please accept my apologies for being so lame!

My 50mm f/1.4 also is "noisy" compared to the modern 12-24mm DX but I believe this is normal. It is slightly louder than my 35mm f/2 which is also much noisier than newer models.

Kent
