Form the very first time I picked up a digital camera I saw the potential for using manual focus lenses with these new systems. Of course it took a few years for things to really become more viable with the introduction of mirror-less. I started off using m43 (Olympus then Panasonic), moved to NEX, Fuji and now back to NEX. Although I wasn't really pining for a Leica. What I wanted was something to recreate the experience I had shooting film when I started using compact RF cameras like the Konica Auto S2, S3 and Olympus 35RC as well as my all time favorite SLR the Olympus OM1n. Those cameras were small, fast, light and easy to focus (the OM1n had a enormous OVF). That brings me to the Leica...I've had the opportunity to use an M8 not that long ago and while i liked the lens (a CV 40/1.4) I wasn't overly impressed with the camera. It was well built but it seemed outdated even back then. I did however find that cameras like the Fuji and Sony struck a really nice balance allowing me to use my old lenses and still have a modern experience. After all digital has a lot of advantages over film and if I wanted a pure analog experience I would still shoot film. I still have a closet full of film bodies. I use the term "Poor Man's Leica" to mean a digital back that supports my use of old school manual focus lenses (why I prefer 40 year old lenses to native ones is a whole different post). The Poor Man's part of it is pretty obvious because I think shelling out $10K for a body and lens is ridiculous. Even if I had the income to support that kind of hobby I wouldn't. If I was staring at 10K that I could spend on camera gear I would immediately go out and book some travel. Life is made up of experiences and that's what I choose to spend money on. Recently I made the switch to Fuji. I really hadn't had any issues with the NEX I had been using for the three years prior but I was drawn to the idea using a camera that promised better image quality and a MORE analog experience while still being a modern digital back. The Fuji bodies even actively evoke the Leica M look with their industrial design. But, what I found is that for my purposes the Fuji didn't quite hit the mark. It's a fine camera to be sure but at the current time it doesn't do a great job of being a digital back for analog lenses. So is the NEX/Alpha platform really the Poor Man's Leica? No, it's not. It's not because the Leica is a system and it includes lenses as well as a body. It's a true rangefinder with one of the finest available stable of lenses. It also includes the M, R as well as myriad of digital offerings using everything from FF to m43 sensors. The Sony is also a system and it has the distinction of being affordable, very high quality, easy/cheap to adapt to use just about any lens out there (including Leica) and great focus peaking makes it a boon to folks wanting resurrect their old lenses. That position will only get stronger if/when we see the Olympus designed 5 axis IBIS makes it's way down from the FF A7 bodies to the APS-C models. So why come back to Sony? Well, it may not be an affordable Leica but it is one hell of a camera. For me it delivers exactly what I wanted. It's small, fast, light and easy to manually focus. It also delivers great results. it's not the BEST camera. I don't believe there is such a thing but it has proven to be the best camera for ME.
