Casio Exilim EX-S12 - Test Shots - ISO Performance

By Cliff Smith



Our Score:


Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality. These pictures were taken indoors using reflected natural light


This is the full frame at 64 ISO.


At the lowest ISO setting the image quality is very good, with no noise.


Much the same at 100 ISO.


Still no problems at 200 ISO.


400 ISO and still looking good.


Still far from terrible at 800 ISO. although noise reduction is visible.


1600 ISO is looking a bit ropey though.


And as for 3200 ISO....


This is the full frame at 3200 ISO.

Am a beginner with this camera. Just gotten. Why? Having had a Casio EX-ES770 for over two year, it gave me fine service, but offered only "SD" quality video. Mr. Smith above gives a fine mini-review. We cannot expect true "HD" or perfection from these minicams, but I do a great deal of YT docuumentation. See " reidwelch" channel for samples of Canon HV30 "near pro" "HD", and then the old Casio 770, and now, the latest: this beginner's first trials with the Ex E12: essentially similar to the older Casio, but HD and with improved audio and video quality. It is not an equal to a dedicated camcorder such as the Canon HV30/40, etc, but =it fits in the pocket= and can be whipped out at a moment's notice (see my video at YT, "Miami Gas Station Robbery"...that was a shock-situation, and I had only the old EX ES770. Now, I can do higher definition if wanted, PLUS, this compression format is compatible with plain, old Windows Movie Maker. It is easy to edit even "HD" footage. See latest, first real test (imperfect as it is) of THE FOUNTAIN, video #17 at both the reidwelch channel, and at the TZ5A channel (same video maker). It will not equal a true "HD" high-price camera: but it works =better than it predecessors, and uses a simple, old-school compression scheme that is easy to edit on WMM that most Vista PC computers have as standard. It is simple, neat, and imperfect...but careful learning of its limitations, should give me in time, exactly enough quality to make quick and superior YT videos for my many YT general and specific documentary accounts. "HD" is now the thing for YT. "SD" is...last year. And, again: you get what you pay for. For the best YT "HD" video, you'd buy a relatively large, higher-bit-rate dedicated camcorder. That's all for now. More impromtu reviews will come for both here and to share at YT. Thanks, all, and Mr. Smith, in particular.

All is changing so rapidly: what's "good" today will seem laughably inadequate in a few years...but, for well under $200US, delivered, this old friend's (the 770) baby brother is just fine. I am happy with it, withal.

I bought my Exilim EX-S12 in Munich an year ago for 150 Euros. It is a wonderful piece of camera and I love it.Video quality is excellent for this price. Unfortunately, my grand daughter ran across the cable when it was connected to my TV and dashed it against the wall. At first nothing seemed to have happened and from outside everything looked fine, not a single scratch. Any other camera would have gone to pieces.Later I noticed the flash and the zoom didn't work. Otherwise I can take photos as usual. Is it possible to repair it? I am in Colombo, Sri Lanka
