I don't have the 18-35mm so I can't say whether or not it will function properly with the R7. But based on my use of other Sigma lenses on my R7, one of which is quite old, I would venture that ...

Add me to th list.  I got mine years ago as part of a new SD1M kit.

In the UK, is a building not considered public property even though it is paid for by the public?

I was speaking in terms of photographing in a place that the public is allowed to be in, within a public building. This seems to be a point of contention to the centre since they consider their ...

This is interesting. Am I reading your comment correctly that, to paraphrase, "it is legal but not allowed"? It sounds like this means that it is legal to do so but the policy of the centre is ...

I agree, good use of the controller ring.  I don't have an adapter with a controller ring but if I did, this is what I would use it for.

I have the Sigma 70-200mm EX DG APO HSM II Macro lens (original production around 2007 or 2008, don't know if mine was made in a subsequent year). It works fine on my R and R7 with the OEM adapter ...

Ive used various methods over the years - blower, brush, viscous, wet. I always first try a rocket blower and if that doesn't work I progress to the other methods in this order: brush>viscous>wet

I've wondered why there is a lack of buttons on Sigma's grips. Someone mentioned in this forum that it might be a patent issue? But there are many 3rd party grips for other brands that have all ...

IIRC, someone else on the forum reported the same issue with his grip some time ago.

My grip doesn't work properly with two batteries in it, I get a few shots only. With one battery it works.

Kudos! Very well played!

Very intersting!  Thanks for your post!

Reverse-engineering does not violate a patent. Sigma reverse-engineers their lenses, whether for Canon, Nikon, Olympus, etc. Sigma has never had any agreement with Canon that allows Sigma to make ...

My favorite sling bags are the Kata 3in1 series bags. I have the smallest and largest ones they made, the smallest being the 3in1-20. Kata has been bought out by Manfrotto who now makes the 3in1 ...

Sigma has not had a licensing agreement with Canon. Canon does not license their lens mount protocols. Sigma reverse-engineers the mounts for the lenses they make. I would have thought by now that ...

As much as that may hurt, the miscreant who broke his wrist will suffer far, far more than you.

I had the fortune to meet Laurence more than a few times, including at his home in Vermont where I got to see first-hand how he intently processed a panorama he shot. He was always gracious and ...

Happy to hear you are on the mend.  My prayers are with you for a full and quick recovery, I've added you to my prayer list.

You're not as ignorant as you might think. It means the same thing here in the USA.
