The Kitstar 200mm is a lens that I acquired very cheaply on Ebay last year – it was an impulse purchase, really, since I knew very little about the lens other than it had a OM mount, and I was intrigued by its unusual maximum aperture. My intention was to compare it with my much smaller and lighter Olympus OM 200 f/4 prime lens, which I absolutely love. I had used this lens on a OM body last spring, and then put it away, meaning to get back to it sometime.

The Kitstar 200mm is a distinctive lens, easy to recognize. It’s all metal and the rubber covering of the focusing rings is reticulated, instead of being checkered as is usual. Kitstar was the in-house brand of Kit’s Camera and they had their lenses made on contract by various manufacturers, so its hard to tell who the original maker is. The lens is solidly built and comes with a built in hood.

I dont know of any lens makers such as Sigma, Tokina or Tamron who made a f/3.3 200mm prime lens, so who knows? Maybe its a f/3.5 rebadged as f/3.3. Kits Cameras was bought by Ritz Camera, and is part of their family of stores. Since Ritz has it’s own in-house camera brand (Quantaray), the Kitstar lenses are no more.

On the Sony Alpha 700, the 200mm f/3.3 lens becomes equivalent to a 300mm f/3.3 lens – that is really fast for a 300mm, and considering the price I paid for it, about $25 or so, it is a bargain. The weight of the lens makes it tricky to handhold, compared with the Sony 18-200mm (also equivalent to 27-300mm, but much slower, since it only goes to f/6.3 at the 200mm focal length).

Anyway, I could easily mount the lens on the Sony Alpha 700 with the Bower-made Minolta AF to OM adapter and took the lens for a spin. Here are the results. The Alpha 700’s anti-shake capabilites makes hand-holding easier, but it was still a challenge to avoid blurring. The Kitstar 200mm (apparent 300mm lens) has nice bokeh.

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.

Ever since the first signs of Spring, I’ve been out with my cameras, not wishing to lose any of the magic of the Great Annual Awakening of Nature. Maryland’s topography is so varied that even though it is such a small state, Spring arrives early in the southern part of the State, especially around Chesapeake Bay and the lower Potomac – almost a full month before it arrives at the Northern regions – near the Pennsylvania border. The rolling hills and valleys of Carroll county are decidedly cooler than DC and the annual cherry flowering takes place almost a week after the Tidal basin flowering

This year (2008) the the Cherry Blossom Festival kicked off on Saturday, March 29 – the flowers began blooming a couple of days before that, and on the 29th, it was close to approaching the peak – and it was 50 degree weather the next few days are likely to be cold and rainy, and we’ll lose a lot of the blossoms. I’m hoping that the flowers last until next weekend. The Festival itself runs until April 13th – but I’m afraid the flowers may be all gone by then. Here are the flowers.. as usual, it was a family trip, but we got separated looking for parking, and never caught up with the other car (which, incidentally, had our picnic lunch). My group ended up snacking at the refreshment stall behind the Jefferson Monument. I was able to walk around a bit under the trees, and here are the pictures. The crowd was very heavy on Saturday.

Anyone ever hear of D.O. Industries? I had never come across any lenses from them until I suddenly ran into this little beauty on EBay, going really cheap. It seemed to be an enlarger lens, but it had what appeared to be a T-mount type threaded mount. A quick email ( an even quicker response from the seller) confirmed that the diameter of the threaded end was indeed 42mm, so I took a chance on it and picked it up, since I was looking for a 135mm lens that would fit on my Spiratone Bellowscope.

I already have a nice Spiratone 150mm f/4.5 bellows lens, but I’m the curious type, and more than that, the name of the 135mm lens intrigued me. The lens itself is small, and solidly built – probably 4 element (maybe 6). Not sure if it is coated. The body looks old and appears to have seen much use, and the paint has faded, but nice glass. It was probably a workhorse lens on someone’s enlarger for many years. It even came with the retaining ring, which is rare these days.

I did a little bit of research on D.O. Industries, and here’s what I came up. Apparently they were an importer and distributor for Fujinon lenses, and they also sold lenses under their own name (rumor has it that D.O lenses are made by Fuji. The optical quality certainly seems to bear that out).

D.O. Industries was started by a gentleman by name David Goldstein in 1972. The company is still around. They are now called Navitar, and you can read their timeline here. I’m glad they’re still around. They seem to be doing well in the current digital era with new imaging products. Innovate, Evolve or Die, right? The photography marketplace is pretty ruthless, with old-timer companies closing down almost every day.

In case no one’s noticed, practically every 3rd party lens company had names ending with –AR. It seems to have been vogue with photographic companies back in the day. You see products with names such as Vivitar, Albinar, Astranar, Rokunar, Lentar, Kitstar, Macrotar and so on. I’ve often wondered why.

When I tried to fit the lens to a T-mount, I noticed that the thread, while being very close, was just not right. It seemed to be more like 41mm, but the pitch was OK. I got around this by wrapping a piece of light cotton sewing thread on the lens thread, and it works just fine. Curious. As long as it works, I am happy.

The advantage of using a longer focal length lens on the bellows is that it permits a longer “stand-off” distance. A short focal length lens (35mm, 40mm or 50mm) can give greater magnification, but the focusing distance is very short, which means that the light is cut off drastically, and one has to use supplemental lighting. The longer focal length bellows lenses (75mm, 135mm and 150mm) can focus from 18 inches to as far as 3 feet away, which lets a lot of ambient light get to the subject. Besides, there’s room for the tripod legs if the subject is 24 inches or more away.

Since I was trying out this lens indoors, I just used a pedestal lamp with the Sony’s WB setting to Tungsten lamp. I used a Auto ISO setting. The exposure was 1/5 to 1/8 second, and I was able to stop down to f/8 to increase the depth of field. If I were outdoors in natural sunlight, I would have used 100 ISO and a smaller aperture.

The tripod permits the longer exposure without shake. To avoid inadvertent camera shake during release, I used the Sony’s self timer setting (Drive Mode button, and then select self timer 10 seconds). This ensures that there is minimal shake. The Sony doesn’t have mirror lock-up, but it’s superbly damped. The mirror return ‘snap’ doesn’t seem to affect the image in any way.

For subjects, I used some of my wife’s traditional jewelry. Without more ado, here are the pictures

The Bellows mounts to my Sony Alpha 700 with a standard Minolta AF-T mount adapter, and the whole thing goes on a cheap Velbon tripod. Nothing special. Here’s the setup.
