Today I tried a 10x42SF at my local optics store, and I thought, why not share my findings here?
It's my personal opinion, so please don't shoot me for it.
First impression, it is very light! About the looks, that's not really my cup of tea. The grey color looks very cheap, and I wonder how they will look after a couple of years of field use....
Ergonomically I think it's very nice. Holds comfortable, and gives a nice relaxed, easy view.
Optics:
The SF provides a nice image, sharp, bright, nice contrast, wide FOV, but it has a bit softer edges than an SV.
CA is very well controlled. Colors seemed to be at the colder side compared to an SV, more clinic, and a bit "emotionless"
What immediately caught my attention, the field seems not very flat! It has a fair amount of pincusion distortion, in such a way I wouldn't actually consider it a flat field.
When panning across the bell tower of the church, I could actually see it "bending". The SV also shows a bit of pincusion distortion, but this seems to be a lot less than the SF. Too bad I didn't have a SV next to it, I'll try to do a side by side comparison as well.
This makes me wonder about some people who find the SF to have more RB effect than the SV. Theoretically the SV should have more RB effect because of the apparent flatter field, but I'm no expert regarding to this, so I could be wrong here.
Another thing what caught my attention, I wouldn't say the "S" in "SmartFocus" of this particular sample is standing for "smart", but something else...... Uneven feel with some heavier turning spots when focusing, and not smooth at all. It likely is exemplary for this sample, but you see it's not Swarovski onky, but happens with other brands too.
Conclusion, Very nice bin without a doubt, I can understand that people are falling for it, but it's not my personal taste.
It should be considered the opponent of the SV, but to me they actually are 2 rather different binoculars. It all comes down to a matter of taste.There are no "best binoculars", it's about which one suits a person best.
Cheers,
