Sony includes a limited one-year warranty on parts and 90 days on labor, but offers extended service plans. Considering this is an expensive first-gen product, you may want to add one if the budget allows.

    Main control ring not as precise, Sun washes out LCD, Complicated onscreen info, Touchscreen can be unresponsive

A compact camcorder offering high quality at a reasonable price is hard to find, but the AX100 delivers. The 1 CMOS sensor is larger than most in cameras of this size along with a prosumer interface many Sony users are familiar with.

I bought this camera to replace an older Canon HD camera I picked up in 2012. I mostly do still photography with Nikon DSLR's, but I like to have a good video camera lying around to shoot with occasionally.

Over cautious I always research as much as possible before purchasing anything. This video camera met all of my criteria and exceeded my expectations . Twice I have let independent film producers use this video camera when we were on film location scouting trips and they were very impressed with the...

This camera blows the Canon HF G30 away. As soon as my Sony AX100 arrived I did side by side testing between the 2 cameras. Even with the Canon 20x zoom the Sony blew it away in long range closeups. I sold the Canon immediately. There is no better small form factor video camera on the market today.

    Solid Built Great pro-level features Video quality is beyond amazing

    Like most cameras it hunts for focus in certain low light conditions. The location of the focus assist button is next to impossible to reach while recording. Whoever designed that location should be fired. Still waiting for Sony's promised firmware update that will enable 100mb/s recording.

Easy to use, some funny button position lit the focus magifiier but an amazing picture and in low light as well. better that the AX33 I have although the AX33 has a better stabilisation system. Took a bit of menus could be better i.e. have user designed shortcuts to make navigation easier.

I bought the AX100 as a replacement for my very trustworthy Sony HDR-XR550 which is still going strong. I have only used my new AX100 a couple of times so far and tested all the recording modes and the results are great and processing is good in both Adobe Premier Pro and Elements my PC handles...
