That is, it might do fine for a sport like baseball, where the action frequently happens at certain well-defined locations (the bases), but would likely struggle with a sport with wide-ranging action like soccer or football. My guess is that some electrical connection inside the lens looses contact in some mechanical situations, maybe getting stretched when going beyond 200mm focal length. Di III has 15 optical elements in 10 groups including one special dispersion element but no aspherical elements.I took pics at a house concert and the combination never refused to focus and it was really dark there.

As with all the other lenses in Tamron’s E-mount stable, the 70-300mm has a 67mm filter thread, enabling you to use the same screw-in filters across the range.Further out from the centre, sharpness is a little lacklustre at wide apertures, and is relatively disappointing towards the edges and corners of the frame. The larger pixels of our full-frame Canon EOS-5D test bed make for somewhat better blur performance. This lens has been available for the Sony E mount since 2020, and Tamron announced Z-mount compatibility in August 2022. In August of 2010 Tamron released an updated version of its 70-300mm telephoto zoom lens, with a few notable improvements.

IF-ED, it's fast, ultra-quiet and comes complete with full-time manual override in single or 'one-shot' autofocus mode. IS II causes Err 01 only when zoomed beyond 135mm I suspect it could very well be a similar problem with my lens.On the Tamron 70-300 the focus ring turns the way Nikon users are used to and it has the non-linear gearing which most lenses for mirrorless cameras offer.
