Micro Four Thirds mirrorless camera systems promised us lenses that are more compact but fully featured. That promise has finally been fulfilled—and it took Tamron, the master of the All-in-One Zoom, to make it happen.

Starting with the 2014 CES trade show, held at the turn of the year, and continuing through press time for this issue, we’ve seen a goodly number of new products come to the fore. All this is only the start—this being a photokina year we’ll see a whole new round of products, including CMOS-sensor medium formats, with prices to match, coming our way. I trust that this report will give you a good sense of what’s here and what’s coming down the pike. So, here are my quick picks of those products that caught my eye, plus a snapshot of some of the trends.

If a visitor from another planet arrived on Earth and asked to see the perfect specimen of what a digital camera and lens should look like, this combination might be the best choice. In terms of design and construction, fit and feel, the Leica M with 50mm APO Summicron is nearly perfect.

Misprint? No. The latest “all-in-one” zoom lens from Tamron ranges from 16mm to 300mm, the equivalent of 24mm to 450mm on my Nikon D300s (with APS-C size sensor). Add Vibration Compensation (VC), excellent Macro focusing and PZD Piezo Drive for quiet and blazing-fast autofocus and you’ve got “Lensational.”

Sigma’s 18-35mm f/1.8 DC HSM is part of their DC series of lenses designed for APS-C-sized sensors so the imaging circle is matched to the size of the sensor. For this assignment, I used a Canon EOS 60D with a 22.3x14.9mm sensor, producing an equivalent angle of view of a 28-56mm lens. Shooters of Nikon, Pentax, Sigma, and Sony cameras, the other mounts for which the lens is available, will achieve an angle of view equivalent to 27-52mm. Unlike other lens manufacturers, Sigma priced the different mounts the same ($799) so don’t feel you’re going to be paying a premium for your camera choice. Bucking a trend with camera manufacturers’ lenses, the Sigma 18-35mm f/1.8 DC HSM includes a lens hood at no extra charge.

A tilt-shift lens can be thought of as a flexible visual tool in the many ways it allows you to image the world. Unlike a standard lens, even a zoom, with a set point of view enforced by stance, elevation, focal length, and, within certain limits, depth of field, the tilt-shift lens opens visual doors a “fixed” lens will not. By tilting the lens within the mount you can enhance or greatly diminish depth of field beyond the “normal” abilities of the focal length and aperture setting. By shifting the lens you can “fix” perspective distortion or exaggerate it for “trick” effects.

The 70-200mm focal length has been the standard tele-zoom choice for many years, offering near normal to a good tele range that suits many practical purposes. Yet, quite a few stock-in-trade 70-200mm lenses had been slow or lost significant aperture as soon as you left the shortest zoom setting, making them a real challenge for handheld, low-light, or even max focal length shooting. Certainly, improvements in sensors and processors in terms of the high ISO/image quality ratio have helped. If you’re too slow on shutter speed with a variable aperture zoom you can always jack up the sensitivity. But that’s not always a great choice and it seems to force you to compromise image quality just to make up for the lens losing “speed” just when you need it most.
