Posts Tagged ‘Christman Park’

Christman Park is located on West Deer Park Road in Gaithersburg, MD set in a residential neighborhood, surrounded by a couple of large apartment complexes. Deer Park Road connects MD 355 (Frederick Road) to Muddy Branch Road and it’s a quiet and very serene. There’s a small pond, a few benches and a stand of fine old trees. The Park honors a young officer killed in action during the Vietnam war, and there is a plaque with a citation for his bravery under fire and his heroic action against heavy odds. I was at the park a couple of months ago when it was still cold and frozen and haven’t been able to get around to posting these pictures until now.

I used the Sony A700 with the Sony 18-200 lens, but I also had an old M42 screw mount 50mm f/1.4 lens from the Yashica TL Super that I wanted to test.

These are the pictures taken with the Sony 18-200 lens.

The Yashinon 50mm f/1.4 is a fine old lens, and I mounted it on the Sony A700 using a Minolta AF-M42 adapter. The adapter doesn’t push the pin at the back of the lens down, so the lens doesn’t stop down on the A700. I was shooting wide open – at f/1.4. On a bright and sunny afternoon, it requires a shutter speeds of 1/5000 second just to be able to get the shot. I’ll have to figure out some way to keep the stop down pin pushed in – perhaps some super glue or maybe some mastic gum. The wide open aperture meant a shallow depth of field with some interesting bokeh. Here are the pictures.

I’ve been so busy testing all my Olympus mount Zuiko and Kirons and Vivitars as well as the Minolta AF, Sigma, Tamron and Phoenix lenses on the Sony Alpha 700 that I feel that I haven’t really had a chance to use the Sony lens that I bought along with the Sony A700 body. It’s the Sony 18-200mm f/3.5-6.3 lens, officially named the SAL18200.

Coming from the manual lenses world, I originally had some trepidation with regards to the extended 1:11 zoom ratio, but I have been pleasantly surprised. Prior to this, the largest zoom ratio lens I owned is the Kiron 28-210mm super-zoom (1:7.5 zoom ratio) for Olympus mount. The Kiron is an awesome lens, but it’s bulky and heavy.

There used to be a time when designing lenses with such large zoom ratios used to mean accepting that there would have to be a compromise in the performance, particularly at the shorter end of the zoom, but Sony has some how managed to make it work. Sony even has a lens with an even larger zoom ratio, the SAL18250 (18-250mm) which has a mind boggling 1:13.9 or 1:14 zoom ratio.

In 35mm format terms, this 18-200mm lens is equivalent to a 27mm-300mm zoom lens, which pretty much covers every shooting situation that one is likely to encounter in casual photography. It’s a very well built lens, but I admit I’d have been happier if the lens had a metal mount like all my beautiful Minolta AF lenses instead of a cheesy hard plastic mount. But such is life. Industrial plastics get tougher, lighter and stronger every year, so I’m not complaining too much, though.

The one thing I am really happy about is that the SAL18200 a Sony “Made in Japan” lens – I expect that the production will soon shift to their Chinese or Malaysian plant. The fact that the China plant didn’t pass the official Chinese quality inspection doesn’t leave me with a lot of confidence in the facility, so I was happy to pony up the few extra dollars for the Japan made label. Maybe I’m just being paranoid, but that’s me. Don’t get me wrong, I’m no China snob, I buy my share of stuff from Walmart and other stores, but I’m particular about my lenses.

The brochure states that the lens has a close focus of about 18 inches, but I have found in practice that it can focus as close as 12 inches at full extension – that’s at the 200mm focal length (300mm) so it’s very useful for close-ups as well as any general photography.

The lens is short – about 4 inches or so, with a 62mm filter, so its about 3 inches thick at its widest point. It’s short enough that the lens barrel doesn’t obstruct the on-board flash even when focusing close. The lens gave me a petal hood as well, which mounts very easily, and I reverse the hood on the lens body for easy transport.

The lens has focal length markings at 18mm, 35mm, 50mm, 75mm, 100mm, 135mm and 200mm (APS format) which correspond to 27mm, 52mm, 75mm, 112.5mm, 150mm, 202.5 and 300mm in 35mm format.

Here’s a series of photographs taken at each focal length detent mark. These pictures were taken at Christman Park in Gaithersburg.
