I like, or would like, this lens a lot too if it didn't cause banding with my E-M5 (also on several other m4/3 bodies). Did all those reviews mention that? If not then I suppose one must take *everyone's* review with a bit of salt since all reviews miss some things or choose not to mention them.

I trust professional reviews, and I'm very critical to all these "findings" and "apparent issues" here, on the forum.

Banding of 1.7/20 is a .. well... myth, non-existing issue. Sure, you have all your rights to think differently, but. please, use your own experience.

Olympus acknowledges E-M5 / 20mm banding and is working on fix

http://www.dpreview.com/news/2012/06/12/Olympus-acknowledges-OM-D-E-M5-banding-with-panasonic-20mm-f1-7-lens

'After checking every possible combination of a body and a lens, we found the phenomena only with this combination (OM-D, E-M5 coupled with the Panasonic 20mm pancake lens). We are continuing to study how we can eliminate this and we recommend for our customers using E-M5 with Panasonic 20mm pancake lens to keep a low ISO to avoid this problem for the time being.'

Believe some anonymous poster who goes by s_grins or believe the engineers at Olympus. Hmm, simple.

1. Based on my personal experience 1.7/20 has nothing to do with banding

Why would anyone be interested in your personal experience? What we should care about is proper evidence and you have never provided any.

2. What is your personal experience? What camera do you use? what lenses do you use? What samples of your photos show banding?

1. I do have this lens. You can find some shots checking this thread

Please don't confuse personal ownership with having proper knowledge or evidence.

2. It is true that I can't prove that 1.7/20 has banding problems, and you know why. If you do not know, the is a simple reason - I've never had any banding problems.

I don't know why I or anyone else would be interested in what you personally think you can prove or not.

Personal experience is a cornerstone of any contemplations and conclusions.

Controlled tests rather than "personal experience" is the cornerstone of conclusions about objective facts.

For reasons already indicated, "personal experience" is irrelevant. What matters is proper evidence, such as that provided, for example, in this thread:

3. Stop BS

Since it is logically impossible to stop doing what one has not been doing, this piece of advice can only apply to yourself, not to Henry.
