published Framed: The Leica Q2,
One Year Later. This article, part field report and part
is based on my field testing of the Q2 in 2019 and 2020 but also looks at the broader subject of framing and
at some of the ways in which the edges of a picture affect the way it is structured (composed) in drawing,
painting and photography.

looks at my impressions of the camera having worked with it in the field this fall.
writer naturally brings his or her own experience and
perspective to the articles he or she writes. My
writing is heavily influenced by my experience working as a
professional photographer for more than thirty-five
years. I'm primarily interested in cameras and
lenses as tools for drawing, as I believe that photography
really is a branch of drawing. As the photographer Henri
Cartier-Bresson once said in an interview, "My
photography is just an instant drawing...I never quit
drawing. The camera is a way of drawing."
I'm also guided by the photographer Andre Kertesz's observation, "I see the thing, I feel the thing, I make the thing". So when I review a camera or a lens, I look primarily at how it presents the world to the photographer (via the finder), how it works as a tool in the hands, and how it draws the kind of picture we call a photograph.
"Quite simply, I think your sections on 'drawing' and and on 'sunny day lenses' are the best writing about photographic lenses that I have read - whether in magazines, journals, books or the various sources online. Few professional writers about photography ever attempt such a full consideration of the range of lens performance characteristics and the different ways in which they are photographically significant. Some discussions in photographic communities online circle around the subject, but don't achieve the focus, rigour and articulacy that you have managed here. Your article is what all writing about photographic lenses ought to be like, yet it's astonishing that next to none of it is. Interesting though Irwin Puts Leica lens book is, it would have been so much more interesting, and so much more appropriate to its subject matter, if it had been written as you have written here...I found the article incredibly useful and interesting. A great help in clarifying and firming up what I have experienced and half-understood about how different lenses work."
Simon Pulman-Jones, England
"We all owe you a vote of thanks for such a massive and thorough piece of work. What a concept-- a "lens test" that is really about the pictorial effect of how lenses draw their images. Lines per millimeter and MTF graphs have their place, but your article really gets to the heart of the matter in the way that photographers can relate to instantly."
- Peter Klein, USA
- Jim Watts, USA
Mikiro Mori, Japan
"...a very informative, even enlightening, work. It not only provides visual evidence of comparative lenses' performance, it also gets right to the most important factor of lens evaluation - how the image looks to the photographer. Long ago I stopped reading test charts of lenses since none of my clients ever published any. It is always the look of the finished image that counts."
Richard Weisgrau, USA
"I hope your tests become a benchmark for other reviewers to pay more attention to the real needs of photographers..."
- Phil Fogle, USA

Reid Reviews is a high-bandwidth site full of high quality JPEGs that, intentionally, are saved with minimal compression so each picture file is quite large (given its dimensions). Preserving the thoroughness and technical picture quality of the reviews requires that the included JPEGs be only lightly compressed.

PayPal, however, this sometimes does not happen for a small
percentage of new subscriptions. The most common reason
for Paypal subscription problems is entering a subscription

When you subscribe, please enter your name exactly as it appears on your PayPal account (if you have one) or credit card (if paying without a Paypal account). Doing so can help to prevent problems with a subscription starting automatically. Name mismatches are the primary reason new subscriptions do not activate automatically.
