Macro Photography – Tamron 60mm Macro Lens

Discover the Tamron 60mm macro lens. Close Up images just got a increase in quality. You can now buy a Tamron SP AF 60mm F/2 Di II LD[IF] Macro 1:1 lens. Check out that lens title. I mean what are all those letters – are they important?

Here’s the break down: SP = High performance specifications (I know, pretty vague) AF = stands for auto focus F/2 = f/2 is the largest aperture for this lens Di II = created for digital SLR cameras only (cannot be used on a film camera) LD = Low Dispersion glass IF = Internal focusing As you can see, the letters indicate lots of technical jargon. Are they required? Totally. Since the letters stand for the lens specifications, they allow us to know exactly what goes in to the Tamron 60mm Macro lens. In spite of the long list, there are a couple of “letters” that could make this an even sweeter lens – VC and USD. Those are the indicators for Vibration Compensation (anti-shake) and Ultrasonic Silent Drive (fast focus). In spite of being excellent additions to the technology of the lens, they would add lots to the price tag, making it too expensive for the many intended users. Exactly who are we talking about when we say “intended users?” It’s intended for those who have APS-C cameras… Oh, no, not more letters. Are you an APS-C camera owner? You are if you own a digital SLR cameras with a modified sensor that is less than “full frame”. APS-C cameras include the likes of the Digital Rebels in the Canon line and the D5000 in the Nikon line. This is a good thing, because the Tamron engineers have focused on a single type of camera rather than trying to make a lens that will be perfect for every camera. There are two features, in particular, that have been mentioned in each review of the Tamron 60mm Macro lens. 1. Super quality images. The excellent image quality was acknowledged, and a few even mentioned that the image quality was a pleasant surprise to them. It must be mentioned that using a prime (or single focal length) lens does give a much better chance for high image quality than a zoom lens. 2. Depth of Field. Bokeh is a term bandied about by photographers referring to the blurring of the background of a photograph. It happens when the depth of the focal plane is not very deep. This is true of this macro lens. It has a very shallow focal plane allowing for a nice blurring effect that helps the main part of the photo stand out even more. This declaration by the manufacturer is significant: The Tamron 60mm Macro lens is the only lens in the World that can boast an F/2.0 aperture at that focal length. The closest competitor has as its largest aperture F/2.8. While the top billing for the lens is for Macro photography, it can be employed for other types of photography. A 60mm lens with a fast aperture such as this one is well suited for portraits. Many photographers use a 50mm lens for portraits, but this one performed admirably for taking sharp portraits. Much has been mentioned in favor of the Tamron 60mm Macro lens. But are there any concerns? Most of the reviews have agreed that there is one negative factor that they observed in their use of the lens. The lens has auto focus with a manual override. That means that you can use the camera to get the focus automatically, but if you feel that you can tweak the focus manually to get it sharper, you can do that. The reviewing photographers seemed to have trouble with this feature, because the lens would try to auto focus while they were using the manual override. This is not an uncommon problem with macro photo lenses. The problem is a result of the very nature of macro photography. The camera is so close to the subject that it tends to have trouble finding the focal point. With the Tamron 60mm Macro lens, the testers agreed that they were able to master this problem, but it was somewhat of a negative in their evaluation. All in all this is a really great lens for entry level to mid level digital slr cameras. This lens offers photographers a reasonably priced macro lens that provides great image quality. The Tamron 60mm macro lens has gotten this comment from every reviewer, “This lens produces great images.”
