By far the easiest electronic video device I’ve set up and I’ve worked in the industry for years. Glad that it has a direct connection and doesn’t require a connection to home WiFi and therefore Russians spies. I recommend this, even though this is just the first day, and the wide angle lens which you need to buy extra. It would be great if the wide angle lens was the default one but I won’t dock them any stars because it works well so far.

First off, it's a nice looking adapter that serves the purpose of connecting your SATA and IDE drives to your PC, or maybe smartphone. The adapter housing is plastic but is well built. The data port to the adapter is USB-C. It comes with two cables that will connect from USB-C to USB-C or USB-C to USB-A. It also comes with a 12V power cable that you'll need when connecting a 3.5 inch IDE/SATA drive to the device that requires the 4-pin PWR connector. The device can be turned on and off with a small switch and it has a blue LED indicator when activity it taking place.The description, in my opinion, is a bit misleading. It tells you that it's USB 3.2 Gen1 (Older 3.0 designation at 5Mbps) and that may very well be true about the USB-C port, but the SATA connector is for sure SATA II based on my speed tests. Reference the attached pictures that show the speed tests. To be fair, it doesn't say anywhere that that adapter is SATA III, but it does mention 5Gbps speeds, which you aren't going to obtain using a SATA II connection. I ran a separate test with another SATA III adapter using the same drive and got very different results for read/write. You can also reference that in the attached pics.All of my tests were done with a KingSpec 512GB SSD with SATA connection. I didn't have any other drives laying around to test so I'm hoping that the other adapter connections are working fine when I need them later on.Overall, this a decent adapter but I would recommended it for data recovery and not for daily use, substituting this for an external enclosure that supports SATA III speeds. When I come across old (maybe even newer) legacy drives that I need to recover data from, this adapter will be very useful and is why I got it. Speeds won't necessarily be high priority in that situation. But, I feel as though it should support faster speeds as it makes reference to 5Gbps and that's why I have to take a star away. Decent product but know what you're buying before you do. 4 stars.

this lens is attached at all times. even with the mark iii extenders this lens is amazin'. seriously, you will love it. DO IT... DO IT!

After shooting with my older EF 70-200mm 1:2.8 L IS USM for years, I started to notice that my images were softer than those taken with my other (newer) Canon lenses. I had it cleaned and recalibrated and while the results were better, I realized that it was probably time to replace it with the most current version.The new Canon EF 70-200mm f/2.8L IS III USM Lens is somewhat lighter and MUCH sharper. I just returned from an out of state nature shoot where I used this lens extensively hand holding it mostly at 200mm. All the images are tack sharp with excellent colour and detail.The 70-200 has always been my 'go-to' lens for many situations... I love the flexibility to choose either lovely bokeh backgrounds or excellent depth of field depending on the situation and the results I'm trying to achieve. This is a GREAT lens and although it's a bit pricy, it has already proven to be a professional tool that does exactly what it's supposed to.I'm really loving my new Canon EF 70-200mm f/2.8L IS III USM Lens and am glad that I didn't 'cheap out' with a less expensive competitors product.

Quality lens for the money. Works great on my 5d mark III.

Great lens for the price! I had a little trouble fitting the 2x converter onto the lens. I sent an email to Big Mike's Electronic's and they responded promptly. I spoke with one of their support reps and he was very helpful. After I attached the 2x converter I took some shots and they are fantastic. This lens is the way to go if you are on a limited budget. Amazon great, check. Lens great, check. Big Mike's Electronic's great, check. Overall a great deal and fantastic customer support.

This head is rock solid! It holds my 5D Mark iii with a 24-70mm lens in portrait mode with no problems.

I use this extender with my 70-200/2.8, 300, 400, and 500mm tele lenses for wildlife shooting (hobby). My cameras: 7D, now upgraded to a 7D II, and a 5D III. Important in particular for 2x TC users: both latter cameras still provide an active center field autofocus with lens+TC combos that have an F/8 initial aperture. In particular every birder knows: you can't get enough focal length. And if you don't want to invest in - and carry - a super huge & heavy 800mm lens, you have to have TC's in your backpack. I use Canon's very good 1.4x MK III TC frequently, and less frequently this 2x TC. Many reviewer's here explained already the 2x TC's technical pros and cons in detail. In real life, according to my experience, you can break it down to those three items that really count:(1) images lose visibly sharpness and get softer, in particular in the edges (full frame) but with re-sharpening during post-processing (or sharper pre-settings in your camera) you can get acceptably good results (= you still can see feather/fur textures) IF...(2)... there is enough light available (!!) for a - with many lenses - quite slow combo AND...(3)... the object does not move too fast and unpredictable, because AF will work as sluggish as an old digital compact camera (but accurate with a carefully micro adjusted camera).This may also be important for you:- Oh no, you can't combine Canon's Mark III 1.4x with 2x TC's to shoot man's first footsteps on Moon from Earth. Canon prevented this mechanically, not only by some sort of pins (you could easily remove): the whole TC's do fit because their lens systems extend from their bodies and would collide before their bayonets snap together. Don't complain, be sure that the image quality of such combos would be too lousy anyway for modern high res sensors. If you need extreme focal lengths check if digiscoping (mostly without AF) would be the better solution for you.- Some lenses do not fit with Canon's Mark III TC's because, again, their extended lens systems would literally collide with the back lenses too close to the bayonet. The example in Canon's lens line that I presume is most prone to such a disappointment is the macro lens EF 100mm/2.8 L IS USM. So check the TC's compatibility with the lenses you want to use it with before you hit the order button. Btw you can pimp your macro's magnification by using extension tubes, plenty of good ones with full electronic supply of AF and aperture are available.Final word(s):Given the fact that a 2x TC is always a quite extreme optical compromise, the Canon engineers did a decent job with the Mk III version. But do not expect any wonders. An EF 400/5.6 lens will always be much sharper at 400mm - and focus much quicker - than a 70-200/2.8 II + 2x TC III combo, I can tell from my own experience.Those who just start with the TC business, I'd highly recommend to go first for Canon's 1.4x TC Mk III. It provides less reach but much better optical and AF performance. In practice you can use it much more frequently and get good results.
