I couldn't decide between submitting a photo of my Canon glassware or my whisky glassware, so I decided to do both. Here's my Highland Park decanter, a Highland Park shot glass seen through my EF 85mm f/1.2
L II USM lens, and a bottle of finest 30 year old single malt. I think this represents some of the best glass available anywhere!
5D Mark II, EF24-70mm f/2.8
L USM @ 70mm, f/11, 1/10s, ISO 400, 580 EX II flash bounced off ceiling.
In case you're wondering why there isn't any whisky in the shot glass, I had to turn it upside down to get this image.
