The SMC Pentax-A Zoom 35-70mm 1:4 is the only zoom lens within Pentax's inventory of K-mount lenses that has a fixed aperture. The twin-ring zoom was produced from 1984 to 1985 for the Pentax Series-A and Series-P 35mm SLR film cameras. The A-series lenses, which saw the introduction of 'automatic' aperture settings on K-mount lenses have both an aperture ring that lets the lens aperture be set manually, and also an 'A' setting which allows the aperture to be controlled by the camera automatically.

The solid and well-built lens, with 7 elements in 7 groups and 6 aperture blades, was produced from 1984 to 1985, and came with a minimum focusing distance of 0.25 meters, measures 80mm long with a diameter of 65mm, takes 58mm filter sizes, and weighs 330 grams, The lens weighs 330 grams. Divided between accolades and brickbats, the lens enjoys a Sharpness rating of 8.3, Aberrations at 7.9, Bokeh at 8.1, Handling at 8.5, and Value at 8.9, on PentaxForums.

I took the opportunity of mounting the lens on the 10MP CCD Pentax K-m (Pentax K2000 in the US) recently and took the camera to the community field across from the road to grab these walking-the-zoom shots against the backdrop of the rising sun. The snug-fit lens felt comfortable in the hand, easy to work with, and was flawless with the lens set to the 'A' aperture setting and the camera working in Program mode. On the equally vintage Pentax K-m, the lens is equivalent to a 50-105mm short tele on a 35mm full-frame camera, a good range for snapshots, portraiture, a walk-around lens, and street photography.

Konica II B, Fujifilm Superia X-tra 400, A Belated Update

Analog Diary, film photography favorites, image making with a Konica II B, and an expired roll of Fujifilm Superia X-tra 400, a belated update.

Took these images a while back, a real while back, almost a year ago, on a roll of expired Fujifilm Superia X-tra 400 which I did not have the chance to take to the lab for processing until only recently. While these images from the expired film images were marvelous, this first outing with the Konica II B was a real test of resilience as I was still a complete novice with fully manual exposures. The shoot, though enjoyable, was a real hit-or-miss session where I ended with more under and over-exposed, and a couple that are out of focus, image frames.

The Konica II B, a model from a well-built series of fixed-lens, leaf-shuttered Konica 35mm rangefinder cameras built from 1950 to 1959, with its extremely acknowledged super bright viewfinder, was a joy to use. Its exquisite ornate body shape with a curvaceous body panel design mimics the outline of the hands when the camera is held to the eye, is a hefty body weight of 681 grams without film, and does not have shoulder strap lugs either. Carrying it around is best in the camera's own leather case, or a container pouch.

Konica II B

While I still do relish the moments I spent with a good or an excellent film camera, the ever-increasing cost of film for film photography, and the timeline of its associated services, is the lament that is pushing me more towards the CCD image genre as the new alternative. Digital cameras with CCD sensors do not incur recurring costs or additional charges when acquired, and are readily available at prices for the asking, may, as some are saying, resurrect itself as the new film.

The Olympus SP510UZ, a 7.1MP CCD digital bridge camera, is another interesting low-cost buy for CCD enthusiasts. The SP510UZ, introduced by Olympus in 2005, comes fitted with a 6.3-63mm Olympus ED lens, and it was the last model of the SP-series (Special Performance) that used the 10x optical zoom lens. The model was later succeeded by the SP550UZ, which has a bigger 18x zoom lens, and the SP-590UZ, which features a larger still 26x optical zoom lens. The camera stores images on xD-Picture cards or its own 21MB of internal memory.

The SP510UZ is powered by a set of 4 x AA batteries, features an EV (electronic viewfinder), a 2.5-inch LCD display, a 10x zoom lens (equivalent to 38-380mm in 35mm photography), and 5x digital zoom in a compact and lightweight plastic body. The camera is also capable of capturing images in RAW format and features Olympus's BrightCapture technology with ISO sensitivity ranging from 50 to 4,000 (though at ISO 2,500 and above the camera's resolution drops to 3 megapixels), and a shutter speed range from 15 to 1/1000 second, and Bulb.

In addition to the range of fully automatic settings that include a suite of 21 beginner-friendly scene modes, the camera offers Aperture and Shutter Priority modes for more advanced photographers. While the camera does not have true hardware-based optical image stabilization, it offers a Digital Image Stabilization mode instead. The system uses a gyro sensor to detect the amount of camera shake and then employs software to select a higher ISO and a faster shutter speed while tweaking sharpening to reduce blur.

Creative Arts, Magic Art Filter, People and Places

Image making with the Magic Art Filter in Drawing mode on the 14MP CCD Olympus VR-370.

I was out and about in the city, trying to capture the essence of the city which is ushering in the CNY 2024 spirit, but it looks like I ended up in the wrong location at a place that looked staid and stale with its own itinerary of events and the spirit they are celebrating. Sad, as it all seems unreal that, in these days and times of celebrative entrepreneurship, I could still find such a city spot that could not motivate or incentivize itself to the prospect of having strong economic returns by organizing and promoting recurring celebrative events.

I had fun, though, instead of doing another shoot for the 'Re-Living the CCD Sensor' series, going for the special effect Magic Art Filter, in Drawing mode, on the 2013 vintage point-and-shoot Olympus VR-370, a small and compact 16MP CCD travel zoom category camera. The mode represents an image in a line art or line drawing form against a (usually plain) background without gradations in shade or hue, done usually in monochromatic. The location, just as well, was perfect for the people and place watch.

Olympus VR-370

The VR-370, almost the perfect CCD vintage collectible, is a stand-out with its 12.5x optical zoom lens and a 24mm equivalent super wide-angle start that extends out to a 300mm reach. The camera has iAuto, Scene selections, Face Detection, AF Tracking, Magic Art Filters, and Beauty Mode. The camera is also supported by Shadow Adjustment Technology for a more uniform exposure across the image, and by Dual Image Stabilization that combines Sensor-Shift Image Stabilization with high ISO sensitivity to compensate for the image blurring due to camera shake.
