Excellent for the money,
Verified Purchase(What is this?)
This review is from: Tamron A005S SP AF 70-300mm F/4-5.6 Di USD Telephoto zoom lens for Sony/Minolta A-Mount (Camera)
I bought this lens as a replacement for the Tamron 70-300mm LD Macro lens that I have had now for about two years. I bought an Alpha 850 a few months ago (full frame) and wanted better glass to make the most of it's potential without being able to afford one of the Sony G series lenses. After reading reviews on this site and others I decided to purchase this lens.
The first thing you notice when you open the box is the size and weight of the thing. It is solid and well made. The zoom and focus rings have good grips on them and there is no play on either ring. They are also impressively smooth in operation.
On the side of the lens there is an AF/MF switch which functions fine and you will see from the picture I have added that there is no vibration control logo or switch on this version as it doesn't need it. The USD motor this lens is fitted with is very quiet and fast. My old Tamron relied on the body's motor and was quite slow and noisy in operation. The AF metering is fast and accurate and works in all but the poorest of light conditions.
One thing to be aware of on the subject of focus is that the manual focus ring is still movable even when the auto focus is in use and if you touch it it will move your focus off. It is not locked off when the AF switch is used so it is something to be aware of when taking a shot. I don't find it a problem though myself.
The hood provided with this lens is deep and does a good job of blocking out stray light. As it is an internal focusing lens it is of the petal variety as it doesn't rotate of course. The one problem with the hood is that it is difficult to replace the lens cap on after you have taken a shot. Also, if you wanted to put a filter on or rotate a polariser that would also require you to take it off first.
I have found the image quality to be good on my full frame camera with only a small amount of vignetting at the the wide open end of the scale. Stopping down soon clears it away and the images are crisp and colourful as you would hope. I also find that CA is well controlled even in pretty harsh conditions.
I feel this is an excellent zoom lens for the money although I can't work out why the Sony version is about £20 more on average (from multiple suppliers) than the Canon and Nikon versions which both have the VC IS system on. Surely it is cheaper to produce the lens without the VC function? Anyway, it is a small thing which you will forget when you start using this lens as it is so good.
Worth every penny.
