Leaf Valeo 22 medium format digital camera backs

A 22-megapixel digital camera is enough to make even Nicholas smile. The camera was picked up at Parrot Digigraphic (imaging@parrotcolor.com) on Monday, and was at work in Guatemala, Central America on Tuesday. We do most of our test photography in Guatemala because of all the photogenic opportunitities here.

Leaf has a long history of digital cameras and scanners as well. The Leaf 4x5 and other dedicated toaster-shaped slide scanners were way ahead of the day both in hardware and software many years ago. However these scanners did not survive the takeover by Scitex. Leaf was bought by Creo, and Creo was bought by Kodak.

The Leaf Volare, Cantare XY, and Leaf C-Most are earlier models. Some of the Leaf backs were the original backs for the Sinar cameras. For several years Sinar sold its own branded backs. But the development costs were so high, and the Sinar backs were not portable. So Sinar dropped out and now uses backs from Jenoptik.

The Leaf Aptus 17 and Leaf Aptus 22 are the new models to replace the Leaf Valeo 17 and Leaf Valeo 22.

The exposure metering tools and gray balance capabilities strike me as precisely what is missing in the Kodak system. So far I would rate the Leaf Aptus and Leaf Valeo as one of the better semi-tethered portable systems yet designed. This statement is made before our upcoming test drive of the MegaVision E5 22 megapixel camera back with OQO monitor/computer.

An 11 megapixel image is plenty for basic portrait photography, publication, product shots, and 90% of what a normal photographer shoots. 17 megapixels is even better. But downside of these chips is their lens reduction factor (we explain this in Nicholas Hellmuth's popular course on digital photography, DP 201 ).

In the meantime, if you need a portable system that may actually function outside, take a Leaf for a test drive.

In nature photography a tripod is essential: here we are using a Bogen carbon fiber tripod with either a Gitzo or Manfrotto ballhead. Camera is Mamiya 645 ADF, macro lens, and Leaf Valeo 22 digital back. If you take a FLAAR course, or order the FLAAR Reports on digital cameras, you can learn the differences between the Mamiya and the Hasselblad H1 (we have used both).

Once Kodak took over Leaf our demo Valeo 22 unit was withdrawn. Thus we are not able to comment on the Leaf Aptus 17 or Leaf Aptus 22 because we have never had one available.

We are comparing the results of the Leaf Valeo 22, a Nikon D100, and an 8-megapixel Sony F828. The quality of the Leaf is superb but you have to see the original prints rather than 72 dpi JPEGs where you can't appreciate the quality. FLAAR has a long range project to compare medium format cameras with other formats to assist photographers who come to us to ask which format they should buy for their work. We find that medium format has many advantages. Later this autumn we will be issuing our findings in PDF format.

Professor Hellmuth also teaches medium format digital photography via the Internet, so you can take this course anywhere in the world . This course also includes large format digital photography and 35mm, so you can learn the pros and cons of each format.

Medium Format Digital Camera Initiative For over 30 years Nicholas Hellmuth has used Rolleiflex and Hasselblad cameras to record the flora, fauna, and Maya archaeology of Belize, Guatemala, Honduras, and Mexico. Now, for the last six years, he is extending his medium format experience to digital photography. Since FLAAR works both in a studio as well as out on location, we are an ideal focus for judging portability. We have experience with large format digital scan backs (the excellent BetterLight) and we also use Nikon (D300) and Canon (EOS 5D) digital cameras. A full-service digital pro should have at least one medium format digital system and should consider large format digital options as well. FLAAR also has an 80-megapixel large format camera (yes, they do exist, we have a Cruse). Although we started with a Leaf Valeo 22 coupled with a Mamiya 645 AFD body and lenses, we are open to showcasing all bodies as well as other digital backs. Indeed we tested an Imacon 4-shot back on a Hasselblad H1 body. For a month (February 2006) it was possible to evaluate a MegaVision black-and-white dedicated back for fine art photography. We are also considering the Rolleiflex 6008 AF, one of the outstanding medium format cameras that still offers European precision. However in the last 40 years we have not received any Rollei (or Franke & Heidecke) equipment for evaluation, so we can comment only on the Hasselblad and Mamiya (loaned briefly two years ago by Mamiya America). Camera resellers or manufacturers who wish to have their cameras, lenses, and backs included in the digital photography evaluation initiative are welcome to send their equipment for evaluation. Curently all the medium format backs are coming from Global Imaging Inc, Greg Lamb, CEO (contact 800 787-9802, press 4, fax 212 722-0988). This is one of the few camera stores in the entire US or Canada that offers ALL major brands of medium format (so they have no incentive to push one brand over the other). However we are also open to receiving medium format backs directly from the manufacturer. Over 381,154 visitors came to this www.digital-photography.org web site to learn which cameras, lighting, tripods, and accessories have proven themselves during evaluation by FLAAR. Since we deliberately do not review low-end cameras, our reviews attract a sophisticated audience. The total "visit" count is 791.562 during 2007, but we prefer to use the visitor count, 381.154 as being more realistic. FLAAR is the de facto source of information on medium format digital cameras because we are university based, independent, blunt, and we are one of the few review sources that dares to review advertising specs, advertising claims, and advertising hype. We can afford to reveal all the pros and cons because FLAAR is a research institute. Photographers feel they can trust a university research professor who has devoted years to understanding the pros and cons of each aspect of a digital camera system and workflow. You can download our colorful FLAAR Reports on our medium format digital camera initiative.
