Minolta AF 100-400mm F4.5-6.7 APO A-mount lens review by WestCoastCannuck
|WestCoastCannuck#44222 date: Feb-2-2019|
flare control: 4
|ownership:||I own this lens|
|compared to:||Sony 70-400G, Minolta 400/4.5|
|positive:||Its a surprisingly sharp lens. I would have to guess that it is very close to the 70-400G even wide open. One of these days I will do a comparison. See some of my samples. Colour seem nice to my eyes. Bokeh not bad for a zoom.|
|negative:||This lens hunts. A lot. With a contrasty subject in decent to good light.... no problem. In less than ideal light it will often hunt - especially with center point focus. "Expand Flexible Spot" works better... and the zone options also work well enough. |
At first I thought the lens was only sharp closer in and weak at infinity.... but then when I manually locked focus I got super sharp images. Though I did not notice, I think the blurring may be a result of micro hunting - anyways, when I locked the focus on my landscapes they got sharp.
It seems to have more distortion than the 70-400G... I could not stitch longer focal length shots without applying some correction first - I found the profile setting for the "Canon 100-400" worked well enough with some occasional tweaking.
Fairly heavy vignetting at the long end - corrects easy enough.
Worst zoom creep ever. Drops like a stone if you let it.
|comment:||I ended up with a well used (glass perfect) copy of this lens by accident at a price that was almost a gift. After using it for a week or so I can say I will be keeping it for hiking and travel when I want the smallest and lightest long zoom I have. |
Handled with care it certainly does not embarrass for results! I plan on testing and using it some more first before it goes on the shelf waiting to be needed. ;)
