Back to the topic.
Rainer I’ve pulled the trigger to buy Tamron 70-300 4.0..5,6 VC for my APS-c Cammeras.
Positive point.
1. Good IQ
- In development announce Tamron mention that will deliver class leading IQ.
- MTF chart on Tamron site seems to be good.
- Internet reviews confirm that too.
- Local Dutch photo magazine confirms that too.
- It seems that sigmas FLD and tamrons XLD glass redefines the lens IQ standards. Probably this glass is coming from Hoya.
2. Good Build quality
– BQ looks better that canon 70-300 IS.
- I like the tamron SP finish.
- acceptable weight – for 400Euro I can get second hand Sigma/Tamron 70-200/2,8 for 400Euro but they are twice as heavy.
3. AF
- it allows MF at any time.
- AF ring works fine. Personally I find it even better that Canon 70-200 IS 4.0. It rotates more degree then canon 70-200 is and 70-300.
- USD works just fine. I’ve compared this lens with canon 70-300 IS usm. Tamrom seems to be a little bit faster but it shakes around settling AF distance.
3. VC is OK.
Limitations
1. No AF limiter – eg. 1,5m…Infinity and 3….Inf. Even that USD and MF works just fine
2. VC has only one mode. I don’t know how this lens will perform by panning. E.g. Birth in fly photography.
Warnings!
- The MTF charts show lower IQ at extreme corners by FF.
