It's a "Walking Review" because it's a "Let's do it" review. First some details; but, in awhile, results from the field. I'll add things as we go walking with the camera, and it gives us its best shots.
With her Canon SX200 showing a few ruinous light bars across pictures, mi esposa kept the faith and purchased an SX710 from BestBuy.ca last evening. She could have saved a few bucks by getting the "safer" SX700 from Amazon, but she managed a $30 savings from BB and return is simple if the camera doesn't perform.
By "safer" I meant the SX710's 20.3mp on its 1/2.3-inch type CMOS chip, versus last year's SX700's resolution of 16 megapixels. I'll let you know/see some results, especially photos taken in poor light.
megapixels
All I had seen myself so far were "can't be done" comments from experts who had never held the camera in their hands. Such comments themselves "can't be done" in my opinion; they are garbage. The "sensors" I grew up with were 35mm film.
On the other hand, I've previously returned two cameras—a Sony DSC HX30v and a Canon SX60—which in my opinion were stumbling over their megapixels. I was pleased to go back to a Canon SX50, returning from 16.1 to 12.1mp. Now we'll be playing with 20.3mp, which will shine on a sunny day, but which will have their work cut out for them in less ideal circumstances. Jenny accompanies me into Costa Rican cloudforests, and we encounter oodless of unideal circumstances in those Edens.
battery charger
In helping her with the camera's setup, so far I've noticed the battery charger is identical to Canon's battery charger for the earlier SX270, which I own. All the math is the same, with output: 4.2V, 0.7A. Not only can you interchange chargers, but their only difference is in their serial numbers.
batteries
My SX270 did well with its NB-6L batteries. And whereas Sony's HX30 refused to accept superior Amazonics (superior because their performance was the same and better, at a quarter the cost), the Canon had no such snobbery. That was another reason I so gladly went over to Canon, generally, after Sony.
But the later Canon SX280, so I've read, devoured its batteries. Now the SX710 has a battery to handle the load; NB-6LH. H for hefty, maybe. $45-$75, mas o menos, on Amazon; versus a mere smidgen of that price for NB-6L un-hefties.
The camera accepts both NB-6L and NB-6LH batteries. The manual lists only NB-6LH. Let's see how well the NB-6L batteries do, along the way.
custom settings
I've become used to having C-1 and C-2 settings on my Canon SX50. I love those two customize-and-save personal settings categories. On the littler SX710, they don't exist, so we'll have to see how useful the P category is. The myriad possible settings on the SX710's DIGIC 6 Image Processor are way, way too intricate to fool with in the moment; it is essential that the photographer can pre-set his best-guess settings well in advance.
60p video (…is for the birds)
I also notice the camera is coy about its important 1920 x 1080 (full HD) video resolution available at 60p. It is available, but not amongst the standard listing of settings. You have to turn the dial to the movie icon, as though the camera is reluctant to do that dance. Why? I guess Canon wants to keep this highly compact camera's functions—which might well make it a superb little camera for bird-watchers—secret. The camera can do 25-750mm, that 750mm max tele being about 15X (750÷50) max (equivalent to your binocular power of likely 8X). Of course, binoculars are brighter and faster, but the camera's max 15X is nothing to sneeze at. My SX50 goes out to a max equivalent telephoto of 24X, and has an eyepiece to greatly help finding a moving bird so the picture is possible. But the SX710 might make an excellent more compact camera, and, for birds that move in split seconds, 60p video is far better than 24p or 30p.
(Canon, please take note; and my apologies for giving out the true power ratings for your maximum telephotos, rather than staying with the conventional lies used by marketing the unimportant zoom extremes, intentionally wrongly, as if they were telephoto reach.)
okay, let's take some pictures
Her camera is pretty much all set to go, now. I am a bit nervous about those P-settings staying empowered, but I hope they do. Today hopefully we'll get some pictures, and we'll begin to see whether the little SX710 can handle those 20mps—basically, we'll see if the camera is a keeper or not.
