Polar F2 Heart Rate Monitor Manual

This watch has some many useful function including calling for help if you fall, heart rate monitor and other health app. I feel like Dick Tracy when I speak into my watch using the intercom or answering a phone call.

Great that he can monitor his heart for afib and take an EKG whenever he wants.

This is the third Apple watch I've owned. It seems that this watch works a little faster than the others. I use it as much for health issues. The Heart Rate monitor picks up the same as my belt. This is an improvement over the past watches. The Blood O2 is good, particularly now with Covid as lung function is an indication of the virus. All in all it's a worthwhile purchase.

This watch is absolutely perfect for my husband and I. We aren't sports fanatics but need to keep track of heart rate. We walk, ride bicycle, and treadmill. This watch tracks it all. Best of all, we only have to charge once every 3-4 weeks. Just wish I could get another one in the white rock color.

I love this monitor. It was easy to set up and the instructions were prefect. I'd buy another one in a heart beat!

Pocketability. Manual control. Great bokeh @ F2. I needed a “little camera” that gave me the ability to capture moments w/out lugging equipment. I’m still getting used to the Fujifilm menus and controls (used to Canon), but has been exactly what I wanted so far. Would love to see it come with a charger, but I get it, gotta keep prices low.

This is my first all manual lens in over 25 years so I had some concerns on how it would work on my new Sony a6300. In summary I am very pleased with the lens. It looks and feels very well made. I like the feel of the focus ring and am able to really fine tune the focus. A few positive surprises. The first is manual focus is easy for what I use this for (astrophotography and landscapes/buildings). It is easy to focus and with the focus zoom feature on the a6300 it can done very accurately. The second is the lens is very sharp in the middle 80% of the photo. I would say it is as sharp as any of the L Series lens (mostly zooms) I have for my Canon 5DM3 and sharper than my 17-40 F4 L even wide open at f2. Yes it is a fixed vs. zoom for the others but it also costs only a fraction as much. It does get a bit soft in the corners/edges but that is expected. Lastly, though manual it does NOT communicate at all with my a6300 (which at first really bummed me out), however, because the a6300 is mirrorless pretty much what you see through the viewfinder (or on the rear display) is what you will get for an exposure. So you can play around with the f stop or shutter speed and pretty much know what you will get. This is was quite a bonus for me and very helpful in the kind of work I do. On the negative there is some chromatic aberration in the usual high contrast bright areas but it was not excessive and I was able to adequately deal with it in Lightroom. Also, the cheap cloth pouch that came with it is not protective so I bought the an OP/TECH USA Fold-Over Pouch #253 which is the perfect size, easy to cover the lens (without the lens hood). The lens cap is a bit loose on it as I bought a B+W 67mm Xs-Pro Uv Haze Mrc-Nano 010m filter to protect the lens. I rarely use lens caps anyway in favor of always keeping my lens in the case when not in use Overall it is still early but I am very happy with the lens, it's wide f2 aperture, apparent quality and sharpness.

- very sharp across field at f2, - manual focus with focus peaking is quick and accurate, - at f5.6 most everything is in focus, - no hard stop for infinity, However, the infinity mark is right on, - chromatic aberration easily managed in Lightroom, - being an ultra-wide the results are dramatic and pleasing, - small, light and inconspicuous, - looks great on A6000. I am really happy with this lens!

i use this as a second monitor and couldnt be happier. tHIS MONITOR PERFORMS JUST AS YOU WOULD EXPECT IT TO. THE REFRESH RATE IS INSANCE AS WELL. VERY GOOD PRICE

Amazing monitor! Refresh rate and clarity is incredible
