Tamron Di-II 18-250 - first tests
September 27, 2007
You might remember my previous posts about Tamron, so, time came for the first results.
My first photos taken with the new lens are already online. So far I like it, the only disadvantages I came across are:
1. Slight barrel distortion at 18mm - easy to eliminate in Photoshop.
2. Vignetting, probably due to the polarizer I have on the lens, also easy to eliminate in PS
3. When shooting straight down or up, the lens can extend or shorten because of its weight. Not that I shoot straight up and down much, but...
But! : I took some test with and without the polarizer, number 2 and 3 were not occuring - it seems the lens is precisely balansed, but if you put on the lens's end some more weight, number 3 may occur. Vignetting is also almost unnoticeble without filter.
Apart from that, it is a fine lens, I love the quality and fine color aberrations control. AF also seems to work flawlessly.
Here are some examples: long 250mm (wall), 250mm macro (fruit), middle range (chips and crisps)
