Brightcolours, thanks for coming to my defence, but:



-I am not French, althought I live in France

- I speak French about as well as English (I have lived and worked in English for 30 years)



I do not understand what either of you speak about <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />

I was referring to the word 'piqué'. The thing about parallel cords was wrong the Wikipedia article about the words. I gather it's something about detail/microcontrast/overall feel, but can you define piqué a little more precisely?



Thanks,

Why did you not say that right away <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' /> Yes, piqué quite simply means sharpness! My apologies, I should have used the English word right away! Kindly Vieux Loup

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.

My tamron 70-300vc seems to be well centred and AF is spot on at all FL and up until 10meters distance.

My lens is a little bit soft at center and corners wide open at 100mm but at 280mm seems to be a decent performer even at 5,6.'Since my living room is only 11 meters I had troubles to do target tests at 300mm. Tomorrow I'll do some outdoor shoots.

Probably I'll keep this lens.
