I cannot speak for the Canon, but I did note a few days ago the Fuji 12x28 IS for sale on Amazon. Used very good was the description. Small mark on body up front missing strap & belt clip. Comes in original packaging. Three hundred und seventy simoleons. Why not, eh? Price seemed right as new goes for 549 USD.
They came in today. They never came w\belt clip and the strap along w\everything that was supposed to be supplied arrived. Lens cloth, warranty card, ocular covers, owners manual, nylon "case" & CR2 battery already installed.
SN 00399XX. Focus close to infinity CW. That's a plus. Colour, esp from a 12x28, isn't going to wow anyone, but the detail w\IS is spectacular. The CR2 is old tech & it would've been nice had they incorporated the slightly longer\larger, 60% more capacity & far more readily available CR123.
The little Fujinon is light w\small FOV & smaller EP. You can view\focus w\o IS activated. In holding the bin your index finger manipulates the IS on\off whilst middle finger works focus.
Low & fast tight turning swallows were a challenge; not only to follow but also in focusing as they can cover a lot of territory quickly.
I generally use Nikon MONARCH 5 16x56 to peek inside the mailbox, from the comfort of the house, to check for mail. It always amazed me how I could see inside of the dark box and recognize the back panel. At 4x and 1.2mm EP less the IS did not disappoint.
I scrutinized the wood detail in the stub left of a splintered limb high in an old oak. As if tripod mounted though less than a pound in weight.
It doesn't have that dripping w\colour saturated Kodachrome feeling and I didn't expect as much. [when I bought the last model Conquest w\Abbe-Koenig prisms the hue to me seemed artificially enhanced compared to less expensive bins w\which I was familiar]
Did I mention how much it kicks arse on detail?
The Nikons also were from beyond the great red wall of China. I picked then up from O.P. for not much more than I paid for these.
So far so good.
ETA: Star test didn't wow me either, but I didn't expect that to be a strong suite for the little bins. Looking as straight up as possible the view was stabilised though I could not balance less than a pound of optics at that angle. Due in part to being a product of the 50's and not a contortionist. Muscles in the back of me neck are killin' me this morn.
Anywho that attempt left me w\drunken sailor\guy on a small boat entire view rolling movement though w\o tremor. I've been switching IS on as needed, off when not. It's my way of saying the battery. I'm the guy that fills up the tank w\petrol leaving the engine running. In the ninth yr, at over 100K mi, that equates to many saved turns on the starter.
I decided to hold the bins upside down as I've yet to mount the strap. Within a few minutes they powered down. However, they do not power up when I bring them back up to bear. Why would they when not powered except that entails turning then off then back on, two-step back\forth movement, to come back online. Of course I'd rather power up\down manual I only worry about the life cycle of the switch.
For an entry level terrestrial viewing IS bin that is very compact lightweight middle of the road 12X it would appear to be a winner. Any less power wouldn't be appreciated by most. You need the 12X viewed w\IS off then on to see the diff in detail. Likewise the 28mm objectives are small, yet if you go for better view\more EP you sacrifice portability.
The view is very relaxing. The one thing I noticed were heat waves. Temps have been low as of late combined w\uncharacteristically low humidity. Viewing w\IS off I didn't notice light-moderate heat waves looking across the street. When I kicked the IS on they were very noticeable. Unstabalised I could not see them.
I'd like to see the price at 450USD ...
ETA II: To be fair I have railed against IS in the past. I felt the cost exorbonate and w\early Canons anyway once the IS is on the fritz the bin is naught save paperweight. [under the assumption that cost of repair if available could not justify compared to new replacement monetarily] Time will tell on the modest Fuji. At least if IS fails the Fuji can still be employed as a relatively compact 12x28.
Used battery slipped into sleep mode at 4:45. Perhaps that is an indication of remaining battery reserve. W\eye cups fully extended I can rest the bin on brow, have edge of cups on face or back up a mite more for comfortable view. I do not wear spectacles.
I approve of the body w\focus as separate from IP adjustment. No pressure from hands, when securing bins, on setting. Since eye placement is premium on small EP it is mandatory to have a secured setting.
