I bought my STM lens used, if I were to buy new, I would go with the USM version. Not a big difference in price. It feels well balanced for me on a 7D

Hi - I don't find the SL1/18-135 unbalanced at all. It hangs downwards when round your neck, but that's no issue. I've carried it on cycling trips, hiking trips, skiing, around cities, through the jungle and in temples. It's the ideal combination for me. Everyone is different, of course. You shouldn't worry about the balance. Just hold one hand under the lens when shooting - you need to do that anyway to operate the zoom ring. Now if you put it on an EOS M series body, that would be unbalanced!

Hope that helps!

The previous version before the STM had a slow, noisy AF motor, and considerably less good optics. Avoid it.

When folks talk about balance, I think they mean visual balance. How does it look? The 18-55mm on a 7D or 7D II looks unbalanced, visually. The lens looks too small. But it balances fine weightwise.

Similarly with the 18-135mm. Put it on an SL1 and the lens looks too big, out of balance you might say - visually. Hold it under the lens and it balances the weight fine.

So don't worry about the balance. :-)

I have the 18-135 USM and it is a wonderful general-purpose zoom. It is sharp enough for bird photography at the long end IMO.

You must be mis-remeberifying this lens, or all STM lenses for that matter. The ENTIRE point of STM focus is that it is super-QUIET.

No, they are correct, you even said there were 3 versions in a previous post of yours, You may have misread their post.

The previous version before the STM was the IS which was released in 2009 and had a Micro motor which was noisy and not as accurate and optics that are not very good at the longer end of the zoom. They are best avoided.

The STM from 2012 onwards is quiet and fairly fast as well as accurate with its focus and with better optics. The Nano USM from 2016 has the same optical specification as the STM but slightly quicker focus and some say a slightly better build quality (that is subjective however, the STM build quality is quite good).

Regards

My bad for the mistake. You are correct. Thank you for the correction.

I like the way you say the Nano USM has “slightly quicker focus”. My STM version has incredibly fast, almost instantaneous AF and I can’t understand how some people say the Nano USM is so much faster.

EDIT: I just bought the 18-135 Nano USM and it is quite a bit faster. Here is a video I made comparing the STM and USM.

Here's a good review I found on the Nano USM:

He does mention how fast, quiet and stealthy the focus is.

I have both the STM and USM. Both are great lenses. Very versatile, very sharp. The STM seems to focus better when shooting video. And is quieter. I use the USM on my 7D and the STM on my 7D Mark II. I have not used a stop watch to compare focus speed and probably won't as either is acceptable to me. I don't know about the Nano. Hope this helps.

Mike

Nano is the new type of USM used in the new 18-135 USM.
