Paul's daughter dropped her Sony A6000 camera lens into the sand and the repair facility wants $141. She can get a new one for that, which is "bulk international lens." Leo says that chances are it's a grey market item, which comes with no warranty. If that was a camera, Leo would say no. But with a Lens, it's less of an issue. One thing she'll have to be careful of is that more than half the stuff sold on Amazon isn't sold by Amazon, it's just fulfilled by Amazon. So she does run a risk if Amazon doesn't ship it. If it's a reputable company with decent ratings, it should be OK.
Chris has a SONY credit card and he has amassed a bunch of points to use to get a camera. Is the Sony A7 good? Leo loves his Sony A7R II. Great camera. But if you're just a hobbyist who loves to take snapshots, the Sony RX100 is a great point and shoot camera, but it isn't cheap at $1200. And if you have a ton of points, then the RX100 Mk. V is last year's model and it's still a great camera. It really comes down to just how much you want. Since Chris already has an Alpha camera, using the Sony A6000 would probably be a good choice as well.
Alexia wants a better camera to shoot pictures in low light. Leo recommends the Canon PowerShot. They're inexpensive, work great in low light, have a higher resolution and it's very compact. Several have 10x zooms and are very compact.
Doug just got the Sony A6000 camera with a kit lens and he thinks it's a great entry level camera. Amazing camera, especially with video. It shoots though in AVCHD, which is new to him. Leo says it's a very standard format. It's essentially Sony's own version of MPEG4. But don't worry, every editor can import it. If he wants to convert it to a more familiar format, he can try Handbrake.
Bob is going to Africa in September and wants to know of a good camera to get. Leo says that the Sony NEX-5 is a great traveling camera because it's micro four thirds, offers great lenses, and is incredibly light. Leo gave his son an NEX 6 for graduation. It shoots spectacular images, and they shoot terrific video as well.
