I haven’t used neither the Canon 70-200mm f/2.8 or Nikon 80-200mm f/2.8, so I can’t comment on how well they perform wide open, but like I said, most of the lenses benefit from being stepped down a bit and there is nothing wrong with that, especially if your not paying thousands of $/£ for a lens.
Anything I don’t like about the lens, or the images it produces? Well, I’m not too keen on the pull-push zoom design, which makes it almost impossible to zoom in or out smoothly during the recording. With DSLRs I don’t tend to do that anyway, so not a big problem. A bigger problem for me is the presence for the chromatic aberration, definitely not as much as in some other lenses I’ve tested, but it’s almost always there, mostly in out-of-focus highlights and extreme light spots of the image. The bad thing is that it doesn’t really go away completely even when the lens is stepped down to something like f/5.6, so that is my biggest problem.
Nevertheless at this price the images are still mind blowing and this is one of these great lenses that are only cheap because majority are not aware of their existence and this is exactly what the budgetfilmmkaer.co.uk mentality is about; it’s about finding good stuff that is affordable and is good value for money, not about crap stuff that is cheap to buy or even worse, expensive, so I highly recommend this lens, just make sure you buy the one which compatible with your camera, preferably without any adapters that contain glass in them because it’s likely to affect the performance of the lens, softening the image at very least, which would make the whole thing a bit pointless.
Hope this info is useful to you guys and it will help save you some money on your future lenses. Stay tuned for many more lens tests and my future lens giveaways.
