Exposure


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.

A couple of weeks ago, I had posted a series of photographs I made with a Sigma 24mm f/2.8 in a little park in Westminster, at the intersection of Bond Street and Green Street. The Sigma 24mm is an effective 36mm lens on the Sony Alpha 700. I wanted to try a 28mm lens (42mm on A700). I took along my lightweight Sigma 28-80mm (42mm-120mm in 35mm format) and shot from the same locations as with the 24mm, and a few others. It wasn’t as cold as the last time, and I could loiter a little while longer without freezing my poor hands.

When I left the park, I turned onto Green Street and photographed a couple of the historic homes. I ended up close to McDaniel College, so I grabbed a few shots of the school buildings, as well as the corner of Main and Union Street. Here are the pictures with the Sigma lens set up – these were taken on Wednesday morning with the same lens.

The Sigma is truly a versatile lens, and has a macro capability down to 1:2 as well in case you need it. It’s one of those lenses that you tend to ‘fit and forget’ since it seems to feel so natural.

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.

I finally got around to visiting the GW Masonic temple in Alexandria – it’s a shame that I haven’t been able to get over there, since I work close by – but DC traffic is hard to deal with on any given day. I visited on Martin Luther King Day – since it’s a Holiday, there was very light traffic. However, it was COLD!

It was about 28 F at about 4 pm on Jan 21 – the wind chill must have been much lower, but I was inspired by the previous night’s game between the Giants and the Packers playing in -3F, -24 wind chill. If they can play in such severe weather, I should be able to get out and take a few photographs, right? After all, it would only take about 15 minutes. Brrrr.

This monument has been getting a lot of interest from the tourist crowd since it featured prominently in Nicholas’ Cages thriller “National Treasure” – since then, people have been adding it their itinerary when visiting DC, even though it’s a few miles away. On the bright side, they get to visit old town Alexandria and the cool shops on King Street.

I was using the Zuiko 35-70mm f/4 lens on the Sony A700 with the Bower Minolta AF-OM adapter – The lens is an apparent 52mm-105mm lens on the Sony Alpha, and it’s great for general photography and portraits. It’s also a good lens for Architecture as well – but only if you are able to stand back a reasonable distance.

For street architectural photography, I’d still recommend a 35mm lens ( in the case of the A700, it would have to be a 24mm lens to get the apparent 36mm equivalent). In this case, I lucked out since the temple has a lot of open space around it, even beyond the parking lot. It’s easy enough to get far enough back to get a decent full length shot.

At 4pm however, the front of the Masonic Temple is in shade. The rear and side were nicely illuminated. It’s advisable to go there in the morning hours to get a well illuminated front elevation shot.

In an earlier post discussing the DSLR crop factor, I had mentioned that if you really need to shoot really-wide angles, just use your film camera – because ultra wide-angle PRIME lenses (24mm equivalent or better) for DSLRs are still prohibitively expensive. The Kit zoom lens that Sony bundles (18-70mm) and the other lenses such as the 18-200mm and 18-250mm are all equivalent to 27mm at the wide end.

The Sony 16-105mm Zeiss zoom is equivalent to 24mm at the wide end, but markedly more expensive than the other lenses. So if we need 24mm and better, it’s either shelling out the big bucks for the Sony 16-105, and if choosing a prime, there’s not many choices. It’s one area where a film 35mm camera like my Minolta 800si still has an edge especially if you currently own a 24mm lens.

However, if a moderate wide angle is fine, the fine Sigma 24mm f/2.8 AF is still widely available at a reasonable price. On the Sony Alpha DSLR, the Sigma 24 is an apparent 36mm focal length with a 63 degree view angle. A true 24mm has a view angle of 74 degrees.

The Sigma 24mm AF Super-wide II is a particularly good deal, since it is available at a reasonable price. One of the reasons (other than that it’s a 3rd party prime) was that the lens came with a matte black “Zen” finish that tended to flake off easily, giving even well cared for lenses a used and battered appearance. This means the prices are often substantially marked down.

My recommendation? Don’t be afraid – unless you are a stickler for cosmetic appearances, the external finish does not affect the lens performance at all. It is an excellent lens by all accounts, and I can vouch for that.

The Sigma lens was also re-badged and sold by Ritz Camera as a house-brand Quantaray 24mm lens, but with a different, more durable, though cheesy finish, gold line and all. It’s still the same optics, though. Don’t be fooled by the appearance – this is a very high quality lens. Besides, the Sigma 24mm can be used as a 36mm normal lens, since many photographers prefer a 35mm lens as their standard lens.

The 24mm has well corrected distortions and moderate wide-angle allows us to include more of the subject, having the effect of ‘getting into the picture’ . We’d pay hundreds more to get a similar “designed for digital” Sony (or any other OEM) lens. High-priced lenses are an anathema for the thrifty amateur, of course.

These pictures are from Westminster, MD – the little park at the intersection of Green Street and Ridge Road (MD Rte 27) looking towards St. Paul’s Church and Green Street. I used the Sigma 24mm AF lens on the Sony Alpha 700 – the 1.5x digital crop gives me an apparent focal length of 36mm. The soft morning light with a light overcast sky was just right.

I was up in Westminster again a couple of days ago, and on the way back, I drove out towards New Windsor. I took the old winding Wakefield road to the Strawbridge Shrine – it’s been a while since I stopped there, there have been some changes – first, they finally erected a second life size granite statue – of Elizabeth Strawbridge, the good pastor’s wife and companion.

I wish they had placed the statues lower – more eye-level, so to speak. The pedestals somehow seem too much. These were simple farming folk who were called to spread the word of God. Robert Strawbridge was never ordained, and thus faced a lot of criticism and censure for daring to preach. When called upon to defend himself and his actions, he is said to have replied “No right but that of the Divine. The Need creates the Grant”. The good Bishop Francis Asbury of Baltimore wasn’t having any of that, though. Apparently, he gave him a really tough time.

In spite of all that, Robert Strawbridge’s ministry thrived, and grew. That whole part of Carroll County – New Windsor to Sam’s Creek is called ‘Strawbridge Country’. It’s bounded by Rte 27 to the East, Rte 140 to the North, Rte 407 to the South and Rte 31 to the West. The area is very rural and picturesque. Archaeological opinion is that the site may not be authentic, and that Strawbridge may never have lived there.

Be that as it may.. .it does not matter in the least. There is a sense of peace and serenity at the Strawbridge shrine that whether or not the good man actually lived and preached in that spot, you understand the spirit that drove him. It’s a shame that he never made it into the Heroes of Methodism book (published in the mid-1800’s) along with other primitive preachers like Bishop Asbury and others. Guess you had to be an ordained minister, or a Bishop. The irony of it all is that the museum at the Shrine is named after Francis Asbury, the very man who tried to put poor Robert and Elizabeth out of business.Correction: David Bearr wrote to let me know that the Visitor center is actually named after a Asbury Smith, a Methodist minister who helped develop the site. I apologize for the error.

It was almost sunset when I got there, and very cold. The light was fading fast, and I just managed to get some photographs. Unlike my previous visits, where I was using film, this time I had the Sony Alpha 700, so I could switch ISO’s quickly to accommodate the fading light.

I switched between a couple of lenses as well. Most of the pictures were made with the Minolta 35-105mm (52-157.5mm eq. 35mm format) and the rest with the Sigma 24mm wide angle (36 mm eq).

I even had a chance to chat with the site curator for a few minutes. Rev. Laura Apostol lives right next door and offers guided tours from April onwards.

I mounted the Soligor 500mm mirror on the Sony A700 using the Minolta AF-Olympus OM Bower adapter. The Soligor is a T-mount lens, but I’ve been using it with an Olympus T-mount for so long, the ring is hard to get off. I just mounted the Minolta AF mount adapter right on to the lens and then mounted it on the A700.

The light was poor, and since I was shooting in Manual Mode, I was using ISO 200. The slow shutter speed I was using was no help. Even though the image stabilization helps out, I’d recommend that with the 500mm lens, a shutter speed of at least 1/250, even with the anti-shake.

The bokeh from the lens did not show the characteristic mirror lens “donut” shape, but that’s probably because the diffuse light from the overcast sky did not cause any bright spots or highlights.

The pictures aren’t great, but I hope to do better the next time. Keeping in mind that the Soligor C/D 500mm behaves like an apparent 750mm lens, the possibility of being able to hand-hold the camera is in itself pretty remarkable.
