Dreadful move by Canon. This was a barely mid-level slightly large compact in a world where only the lowest level offerings typically feature AA batteries. Those who cherish the inconvenient Li-Ion power source are showered with options, have been for years and are more so in the last 3-4 as just about every manufacturer surrenders to complaints of 350 instead of 380 pics on a charge despite the considerable tradeoff to get those extra minutes.
The scarcity of AA cameras and abundance of lithium means Canon simply threw away a huge market by pitting themselves against an entirely new group of contenders for the small number of alluring items now left to talk about with the SX170.
Let's see,
1. Manual control for $200 or so: Panasonic, Sony, Fuji, Nikon and others.
2. 16x zoom: Everybody, and plenty further in even smaller bodies.
3. No tilting or articulating monitor with that moderate zoom, no AA batteries: Everybody.
4. Lack of a viewfinder: Yeah, everybody.
I guess that's why the price has been lowered. They destroyed this line altogether, leaving no reason other than saving a few dollars to buy. At $140 (it was $170 last time checked), it fits okay above the Canon A1400 with its 5x zoom and AA batteries, going for $90.
As for me, I am clinging to my Canon Powershot SX10. It operates terrifically on AA batteries, an option killed with the SX30 and all of them (SX40-50) since. The viewfinder experience was also effectively destroyed on the SX30, which has kept me waiting and waiting for anybody to whoop the SX10 with enough features to surrender my precious $2-each rechargeable AA batteries.
Panasonic came close with the fz200, though reports about slight softness of images speared that route. The Canon SX50 has that massive zoom, though a deplorable viewfinder down HALF the size of my SX10, it's uglier, the dreaded Li-Ion requirement and some other failing that is escaping me at the moment.
Anyway, if I had frequent need of a largish compact with manual controls, count me as one who would MUCH rather grab an SX160 (used or new) for the better battery choice than a newer SX170 even at a $20-30 dropped price. Who needs more things sitting around in a drawer that would cost $35 dollars JUST TO TURN ON one more time? Since I already have a stack of AA and AAA batteries (plus a charger in the van), an old camera in the drawer can be pulled out 10 years later and be used for free. Yup.
Oh yeah, failing to use the Li-Ion things is the surest way to kill the battery. So laying the camera into storage for a while is the surest way to place it on the probably never to be operated again shelf.
Let's take stock of what Canon has murdered recently by designing down:
1. The G12 died, I guess becoming a more limited G15 worthless nothing, no moveable back screen, no zoom improvement, the WORST viewfinder in modern history during the entire run.
2. Powershot SX20 was the last worthy offering in the line. Mine is the SX10, though the 20 was still okay despite losing a couple of cool items. The SX30 got dumbed down in vital ways while merely increasing zoom.
3. Powershot SX160 - No useful feature improvement, just the dopey battery change, a wee amount smaller. Don't they already have one in that category, an SX280 or something?
It seems that Sony has an interest in producing enthusiast level cameras that use common sense design. I am expecting professionals before long to be shifting in that direction. Nikon is at least competing. We shall see if Panasonic bothers with a successor to the FZ200. A recent dumbing down of that series is foreboding though. Then there's Fuji, offering really innovative stuff, yet failing to get the pictures sharp enough to match the features.
My rating of the Canon SX170: If free as a gift, nah, sell on eBay for a used or new SX160. The thing has no purpose on this planet. And for that reason, it warrants zero stars. I am giving half a star in order to keep anyone from thinking that part got overlooked.
Oh, I should add that the SX60 I tried took decent pictures, even at night. The SX170 might also. The problem being the aforementioned lack of measuring up to the competition in the category Canon dropped it into by removing the lone distinction from that pack.
