The Lumix 45-200mm lens is not so sharp

A week ago, I shot several photos using a Lumix GH-4 and the Lumix 45-200mm lens, and then shot the same photos using a Nikon 1 J1 with the 1 Nikkor 30-110mm lens. Much to my surprise, the Nikon 1 photos were consistently sharper and better looking! That’s a surprise because the Nikon 1 has a 10.1 megapixel Super16mm film sized sensor while the Lumix GH-4 is 14-16 megapixels on a 4/3ds sensor!

The problem turns out to be the lens differences.

I did some testing and the Lumix 45-200mm lens is not so sharp at the long end. When I replaced that lens with the Lumix 20mm f/1.7  – or even an ancient Vivitar 135mm Minolta MD/MC mount lens – I obtained sharper results in my test photos. I also found my old Sigma 28-70mm Minolta mount lens, and the Minolta 50mm f/1.4 lens (at f/2.8) were all sharper.

The positives for the Lumix 45-200mm are its inexpensive price and its the optical image stabilization, for which their is none on the old manual lenses. The GH-4 has a far better auto focus mechanism than did the GH-2 and does a great job of auto focus with the 45-200mm lens.

Update: Early version of the lens firmware had a soft focus problem at the long end; this was fixed with a subsequent firmware upgrade.

On the other hand, the Nikon 1 cameras and the 1 Nikkor lenses are amazingly sharp with excellent contrast.

Will VR be the next step beyond 3D?

The need for special, sometimes-expensive, glasses to view TV in 3D is the most-often-cited reason for its failure in the market. Lack of source material has also been a major issue. Ironically, the companies pouring billions of dollars into various not-quite-ready or on-the-drawing-board VR products have doubled down on the need for glasses — their solutions all require even more onerous and expensive goggles. Beyond hard-core gamers, many of whom will put up with ungainly VR headsets to get the benefit of immersive gaming, it’s not clear how many users will put up with the inconvenience of headgear — although much like the IMAX franchise, there will be a niche market in immersive experiences using those same headsets.

Emphasis added by me. The same reporters babbling about the alleged inconvenience of 3D “goggles” for 3D TVs at CES went into hyperdrive of excitement over virtual reality (VR) helmets.

Glasses were not the problem: the problem was lack of compelling 3D content. I am guessing that glasses free displays delivering 3D gaming content on phones and tablets might make a resurgence. Games provide immediately available 3D content.
