Input:
Question: Is there a document that details the exact SD cards that are compatible with the dmc-zs40.  Page 25 on the directions is general / link not better
Document: I'll test out sending Multiple pics when I have a SD card.
It's really disappointing. Also, I have yet to get this to connect to my wifi, and its been difficult to locate a compatible replacement cable on amazon.Dont let this deter you, though, if you want a solid pocket camera with amazing zoom and some other nifty features.
Amusingly they do surveys after support chat/call with the former just redirecting to the home page, and the latter not recognising the numbers you type 3 questions in if you are giving dissatisfied answers!
I was really disappointed.the image quality deteriorates fast when using zoom. too much noise. my old Samsung WB650 did a better job than that in terms of image quality. also it's not comfortable holding it.
I bought this Lumix ZS40 camera very recently. I like all the features in it and its compact size. I was using a Lumix ZS20 which had its limitations, but I liked its versatility. Hope this ZS40 will perform better than that.
Yes there is noise at higher ISOs (above 400), but I expected that and it seems very good to excellent for this class of camera. FYI, [...] has sample shots and nice review of the Canon sx700 with a comparison to Panasonic zs40.
The &#34;built in memory&#34; of the camera only supports one photo. I don't understand why, since the built in memory is supposed to be 12 MG. So until I can purchase an SD card, I can only take one photo at a time when I'm trying out the different camera modes.I love the ability to send photos via WiFi to my SmartPhone (I have an iPhone 5).
We do apologize for your inconvenience but unfortunately the software that was provided with the camera is not compatible with MAC at all and as a result we recommend using Imovie 11' or higher as well as Iphoto in order to transfer your videos and pictures.We hope this information is helpful to you. Thank you for contacting Panasonic.On their suggestion, I tried iPhoto (I could not however imagine why Apple's lesser product would support something that the superior product did not).
In low light, not so much. It's not that it performs poorly, it just performs like a small sensor digital camera with a relatively slow lens should perform. Flash pictures are better than on previous models, but if you try to take advantage of the zoom in low light, the flash won't be much help at that distance. (Flash photos are much better at the short end of the zoom range.)
I just returned from two weeks in the Arctic where weight limits on gear is limiting. I kept saying " this camera can't be as good as it is"  The optical zoom to 720mm is amazing. I wish I had a tripod with me as the results would have been even better than there are. The zoom movies I took were great, but annoying sound from zoom gears is very evident on the video.
Answer: I've found that ALL "SD" cards will work.  SD is a standard for the card size and performance.  Even though all SD cards are the same size and will fit and function in any device with an SD reader, the performance can vary.  I use the medium to high grade (fast) ones for the best performance.  If you are going to shoot HD video you really should use the higher grade SD's as they are faster and will give you a higher quality final image.  Research it some more by "Googleing" SD standards to learn more about SD standards of performance.  You can usually find the higher grade ones on sale somewhere, just make sure the speed is adequate for your needs. Good luck!
