Mid-April is the time for flowering dogwoods and vast expanses of wild mustard growing in the fields all over Carroll County… later in the year, these fields will be planted with Soya beans or Corn, but for now, they are just a golden mass of flowers, gently swaying in the slightest breeze. The dogwoods are something to look forward to, as they appear just as the Cherry Blossoms and Magnolias are fading, and they are much more durable blossoms. April is also the time of heavy rainfall here in Maryland, and delicate blossoms like the cherry don’t hold up well. Here are some of the pictures I took in Gaithersburg, and along Rte 27 north of Mount Airy, on the road to Westminster, MD. Mostly flowering dogwoods and fields of mustard blossoms – and a few redbuds.

It was unseasonably warm last week, with temperatures in the upper 50’s and even 60’s. Tuesday morning was unusual, with moderately heavy fog all along Rte 27 running North towards Westminster. The mist changes the appearance of the familiar landscape, and the soft morning light makes for some excellent photographic opportunities.

As I drove along Rte 27, the mist slowly lightened until it was completely burnt off by the time I got to work. I stopped at several familiar spots along the way to take these pictures. I had the Sony A700, of course – with the Sigma 28-80mm still on it from last weekend’s hike along the Great Falls towpath.

The Sigma is an unusually light lens, and perfect for hiking. It’s no slouch when it comes to landscape and architectural photography either. On the Sony Alpha, the lens becomes a 42mm-120mm, which gives me enough flexibility for most landscape and architectural applications. Although I’d preferred top have a 35mm for street photography, 42mm is acceptable. Besides, a 42mm lens presents the world with a slightly better perspective than a 50mm, with no distortion at all.

The 2 close-up’s are included to show the macro capabilities of the Sigma 28-80mm.

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.

I headed off to the Great Falls park last Saturday (02/02/08) to hike along the river and photograph the falls. It was beautiful out there… about 50 degrees – perfect hiking weather, although the trails and towpath were still muddy. I was carrying my Sony Alpha 700 and 2 lenses – a Sigma AF 28-80mm and the Tamron 70-300mm. The Tamron was for closeup views of the raging waters. The Sigma is a recent acquisition, and I was trying it out.

It’s still early in February, and we’ve already had a lot of rain in Montgomery county – the average rainfall for February is about 2.85 inches here, and by the 2nd, we already had about 3 inches…. Which means, every stream in the county is overflowing and that the Potomac is running full already. Normally, we’d have to wait until the Spring thaws.

Since my intent was to photograph the falls, I did not mind lugging along the heavy Tamron, but on my way over there, I was thinking about the most desirable characteristics for a hiking lens – good zoom range, rugged, light, cheap, close up capability etc. At the same time, the optical characteristics of the lens should be good enough that you don’t regret the quality of the pictures when you get back.

The more I thought about it, the Sigma I was carrying seemed to be the perfect fit. After all, it had a zoom range of 28-80mm, which is a 42-120mm on the Sony A700. Besides, it has a plastic body, which makes it lightweight. Great optical quality with multicoated aspherical lenses, very cheap so it would not matter if it was damaged or lost – and it has a 1:2 Macro capability, for those occasional very close-up shots of interesting grass or moss or little critters that I might come across.

I would have liked at least 35mm at the wide-angle, but I’ve found that in the open woodlands and hilly areas of Maryland , even a 50mm is sufficiently wide, since one can always step back a few paces to include more of the scene. The Sigma 28-80mm definitely qualified as a Cheap Awesome Lens. Some may complain about the “cheap” build quality – it’s plasticky – but one can’t fault it optically for the price.

The 1:2 macro capability is only at 80mm f/5.6 (120mm f/5.6 on the Sony Alpha 700) and is is a matter of moving a switch on the lens from Normal to Macro position to lock it. Now, f/5.8 is pretty slow, I was able to get decent images even at 100 ISO. I’m not complaining, since I can always increase the ISO to compensate. However, in Winter, with no overhead tree canopy and bright sunlight, it beats carrying an extra lens for the rare occasion one might want to take a real close up.
Here are some of the pictures at the Falls and along the Towpath. The river is very impressive this week.


The Tamron is a beast on the Sony Alpha 700 – it’s equivalent to 105mm-450mm and fairly fast for such a large focal length f/3.5 at the shorter end, and f/5.6 at the 450mm end. Fast enough to handhold at 100 ISO on a bright day. It’s a macro lens as well, and goes to 1:4 along the entire focal length range, which is pretty impressive. This is another Cheap Awesome Lens.Tamron 70-300mm– Potomac River and Towpath
