The Canon 28 135 IS USM lens is an upper/mid-grade lens that can produce quality photos at a very cost effective price. One of the best things about this product is that it has a great focal length range and it produces sharp images and IS. But if you want to try it out, it is still necessary that you consider some of its features so that you can be certain if it is the right fit for your needs. When it comes to its performance, this product is pretty much in league with the other consumer zooms. However, when using the two-part extension of the plastic barrel, you should expect some slight play. You should also not be surprised if you find that the focus and zoom rings are not that smooth. The focus is pretty impressive as well as pretty fast. It can also vary without any noise as it utilizes a Ring Ultrasonic Motor AF. You can also control the focus ring so that it will not rotate during AF. You can do so if you will enable the Full Time manual or the FTM. Another great thing about this is that you can also view some details about the focusing. The only problem is that the manual focus ring is very small and you might have a hard time in controlling it if you have large fingers or hands. The Canon 28 135 IS USM lens can also control flares which can range from moderate to good. Specifically, it can control flares from 28mm to 135mm. This is very helpful especially when used outdoors during sun glare or midday light conditions It also has a strong barrel distortion feature that can be noticed even at a 1.6x FOVCF body. On the other hand, the pincushion distortion effect is also good. It can go strong until it reaches 135mm. However, a balance can be found between the distortion effects at 40mm. As mentioned, the focal range is great up to 135mm. This can be very helpful if you want to have a wider field at a relatively short distance. But you should also know that this feature is rated depending on the infinity focus distance. Furthermore, it also has a very impressive Image Stabilization feature which is very useful especially if your subject is not moving. This can be activated by just turning the IS switch on. Press the shutter and release half way. The maximum magnification is rather low as it can only take about .195x at 135mm. Anyway, this is really not a big problem especially if your subject is medium-sized. You can also add some extension tubes so that you can shorten the closest focusing distance. In general, the Canon 28 135 IS USM lens has a great focal length and impressive images and Image Stabilization (IS). With a very affordable selling price, this is certainly good for enthusiasts and part-time pros alike.
