Tamron AF28-300mm (F/3.5-6.3 XR Di MACRO) Sharpness Test

- 1/800 F8.0 - 50mm - View @ 100%
- 1/800 F8.0 - 70mm - View @ 100%
- 1/800 F8.0 - 100mm - View @ 100%
- 1/1000 F9.0 - 130mm - View @ 100%
- 1/640 F11 - 200mm - View @ 100%
- 1/640 F11 - 300mm - View @ 100%
In reality, I wouldn't stand this far back to take a picture of the clock. In fact, I would get a lot closer. The point of this test is to see how far I can push this lens.
At 200mm and 300mm, the image is a bit softer than the rest hence required a little more sharpening and chromatic aberration is really bad though easily removed. I think shooting at these two focal lengths, the images are still presentable with some help from Photoshop.
Below is another shot I took last week. It was shot at 1/1250s F8.0 100mm (ISO 400) with AI Servo AF mode. You can see full frame and close-up at 100%.

Canon EOS 5D and Tamron 28-300mm Lens


I went out to test my camera again this afternoon. Above are examples of my test. I shot in raw mode, which allows you to have greater flexibility during editing. I used Canon Digital Photo Professional, though I prefer C1 Pro, to process my raw images. I then used Photoshop for further editing such as cropping, removing dust (on sensor), sharpening, density and color correcting.
In this test, I used the Tamron 28-300mm lens. The reason I chose this lens because of it practicality (no need to change lenses), cost and small size. In this case, smaller is better which is great; especially when you're traveling. I wish I have the money to buy Canon L lenses. Right now, Tamron is all I could afford. Based on the tests done in the last few days, I am confident that images produced, so far, from this Tamron lens are acceptable by photo agencies' standard.
So why not buy a cheaper camera with high quality lens? Well, as of now, cheaper cameras such as Nikon D70, Canon EOS 10D etc. means dealing with APS sized sensor. Shooting with a full-frame sensor not only gives you more resolution but also less noise than APS sized sensor cameras would.

Some Pix From Last Weekend




Went to N.J. last weekend. It was nice to get away for a few days: went to a birthday party, had some pho, took a tour on the battleship USS New Jersey and had some Polish food. Click here to see pix. I've also tested my first D-SLR, Canon EOS 5D (no pix posted yet) for my Prague trip in May.
This camera burned a hole in my wallet. I have been trying to bring lunch to work...doing whatever to save some cash for the trip. I need to do some booking on hostelworld.com soon. At least I got the plane tickets out of the way.
Dinner tonight: Hot dogs.
