This is my first L series lens and it took a couple of days for me to get a handle of it. Once we get used to the weight of the lens and feel comfortable, this glass soon becomes our friend. The AF is very fast and quiet, and the IS is very handy. You can actually see that the IS is operational through the view finder. The image tends to become more stable. There is a slight noise when IS is operational. The IS is still on for about 1-2 seconds after pressing the shutter button completely. This is a good feature when you want to quickly capture another shot of the same scene. I used it mostly for portraits and I am very much satisfied with its performance. At 200 mm and f/8, it gives some amazing results. Additionally, under good lighting conditions, the image quality in terms of colors and sharpness is so great that you cannot stop shooting! Wide open at f/4, with APS-C body, the image is slightly soft, but that is because of very sharp and narrow DOF, and any slight moment will become visible at 100% crop. This is a good lens for landscapes too. The color quality is exceptional. Overall, this lens is a valuable addition, and definitely worth the dollar you invest.
There are way better camera's out there. The big selling point to this camera is it can get wet and that's it. I got this camera for free through a work promotion. I wasn't expecting much from it so I took a chance on it. It says you can take it under water but I doubt I'll risk it. I looked at the reviews online before I got it and the reviews were mixed. Most people by this time use their phone to do photos and videos which are just as good. Pros: 1. Windows 7 discovered it quickly and no software needed to install. You could see the camera right away in Explorer. 2. 20 megapixels is good quality. The AVI videos are 640 x 480 screen size. Not 20 megapixels high quality but aren't too bad. 3. The Selfy option is nice. 4. The Video camera is more useful than the still photos. Cons: 1. Opening the slot to load the batteries and MicroSD card is difficult. I suppose it's because the camera has to be waterproof and air tight? 2. Connecting the camera cable to your pc requires you to open the battery slot. Turning it on while the slot is open is tricky. This is a poor design. Better to remove the Micro SD card and insert that into your laptop IF you pc has that option. 3. No stabilization mode so if you shake you hand when taking a still photo the picture will be very blurry. 4. Requires a MICRO SD card (NOT INCLUDED ) 5. Uses 2 TRIPLE AAA batteries (included) and they get used up quickly. Approximately 30 minutes if left on. 6. A little hard to figure out what button does what, but after you fumble through the options, you'll figure out how to use it. The navigation is clumsy. 7. There's a port on the left side of the camera with no explanation at all in the manual. What's it for? Flower icon is for closeups, the other option is for regualr photos. My camera was set in the middle and I learned this the hard way. KNOW THIS! THIS IS IMPORTANT! 8. The Auto settings are not always right, this is NOT a point a shoot camera. Leaving everything on auto does not give you the best photo results. 9. The flash is WAY TOO POWERFUL! It turns everything white if your too close. DO YOUR HOMEWORK Shop & compare FIRST before you buy anything! KNOW exactly what your needs are and what you want. If your hands shake, they DO make cameras that won't be blurry if you move your hand, this is NOT that kind.
These INSTEN Compatible Decoded Li-Ion LP-E6 batteries work as well as the original Canon battery. Since they are supposedly compatible with the original Canon battery, I charge them with the original Canon Charger. An after successfully charging them, I see they provide battery info when viewing the Battery Info menu on the EOS 7D Mark II. Consequently, just like with a Canon battery, you know the battery status throughout it's charge cycle. In my 7D MKII, they last more than an hour under average shooting conditions. However, after 1-hour, it is my custom to replace them with another fully-charged battery. When using the 7D MKII battery grip, I get 2-hours of shooting. I purchased two of these batteries, just for use in my battery grip. You cannot beat Overstock's price on this Compatible Decoded Li-Ion battery.
Having read many magazine reviews on this product, I bought this liens to go with my 50D especially for very low light shooting. Having had many disappointing results I made some test on the lens. I thought my first set of test was faulty so I repeated the test 3 times to confirm my findings. To do the test I place a wooden metre ruler on a table top with the ruler going away from the camera. The camera was set on a tripod at an angle 45 degrees onto the ruler. The focus was on the centre of the ruler which was 2.5 metres (just under 8 feet) from the camera. A cable release was use to minimise camera shake The test was done under low light as I would normally intend for the lens to be use. The following are the average of the 4 sets of test I made At f1.4 - unsharp results - back focus 1.5 inches At f1.6 - unsharp results - front focus 0.5 inches At f1.8 - better sharp sharpness but still not tack sharp - back focus 1 inch At f2.0 - slightly sharper again - front focus 0.75 inch At f2.2 - tack sharp - focus spot on At f2.5 - sharpness start to deteriorate - back focus 1.5 inch At f2.8 - sharpness gone - back focus 2 inches At f3.2 - back focus 3 inches At f3.5 - back focus 3.5 inches At f4 - back focus 4 inches. Testing was not done on other f-stop. If you were to purchase this lens I would suggest strongly for you to test for the best f-stop for your lens.
