Sharpness: Comparison Canon EF 70-210 4.0 Macro vs. Canon EF 70-200 4.0 L IS
Ok, may be this not really fair ... because the old 70- 210 is about 20 years old now and available for about 100 € (used), where the 70- 200 4.0 L IS is relative new belongs to the profi line "L" and costs about 10 times more (about 1.000 €).
I bought the old tele lens first, because I read, that it should have a really good optical performance. After taking some pictures I was some what unsurprised because of missing sharpness. Especially when using 4.0 and looking at the corners ...
After a while I saved enough bugs to buy my first L lens and I decided for the 70-200 4.0 IS. Now I was interrested in a comparison between those two lenses. There is a huge difference, as you will see on the pictures below. In my opinion the old 70-210 is far away from razor sharp, while you can produce sharp images, but not at the corners and starting with aperture 6,7.
How did I take these pictures? I used the M setting of the camera and a tripod and took a picture of the newspaper. I decided for the small font page of stocks. I didn't used sharpening of Photoshop or some thing.
Here is a overview image.
As you can see I chose the upper left corner of the image for the 100% crop below. All shot are made at 70mm ... I am told, that things don't improve, if you use 210mm.
Here you go:
- Aperture f4
- Aperture f8
