Early Spring is a great time to be out in the woods, especially on a sunny day – the trees may still be bare, but the forest floor is bursting with life… the under-story plants, shrubs and smaller trees rush through their flowering and leafing cycles quickly, to take advantage of the unrestricted sunlight – in a few weeks, once the trees leaf out, the canopy blocks off most of the light, and the small bushes go into the “quiet survival mode” until Fall when they get their chance in the sun again!

I’ve been out with the Sony Alpha 700 and the Tamron 70-300mm f/4-5.6. The choice of lens for woodland photography may seem surprising, but I find that the Tamron is very useful – the extended zoom range (the 70-300mm is equivalent to 105-450mm) on the Sony Alpha provides an useful stand-off distance so one can zoom in on an intresting flower or bud from a distance of at least 5 feet away without having to brave the underbrush and wicked looking brambles – the woods around here are chock full of wild raspberries and dog rose brambles. This also has the advantage of not blocking the light.

Besides, the Tamron 70-300mm is also a 1:3.9 macro, and since can focus down to 5 feet at the extended end of the zoom range, it does a great job. Moreover, I marvel at the fact that the Sony’s built in anti-shake allows me to handhold the 450mm equivalent lens. I would never have been able to do that with my manual Olympus bodies or even the auto focus Minolta 800si.

By the way, I purchased my Tamron lens about 8 years ago, back in June 2000 – I know they still make this lens, but I am not sure how the build quality has changed, or if it is still made made in Japan. I’ve always been very pleased with the Tamron, and even more so now…. with it’s super-zoom length of 450mm f/5.6 and equivalent when mounted on the Sony Alpha 700, it’s a formidable piece of optical engineering, and very cheap at the price. This is a true “cheap awesome lens”.

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
