Sigma 150-600 Sport

[Kayaker72]

So, I am off on a work/play trip. The work part will be in the LA area and then I am swinging back through Idaho to see family. I am going to take the 150-600S along with me. This will be the final test for it. Weather and wildlife permitting, I'll get to shoot eagles in Idaho and whatever I find near a beach in CA.

But, after a few times shooting rosebuds, mailboxes, birds around my house, and a few quick test chart shots these are my impressions:

• 600 mm...the focal length. It does not feel like as much reach as I had hoped for especially when downsizing samples to 1000 x 600 pixels, but it is noticeably more than 400 mm and is helping get shots. I say this as it is obvious, but at least I sometimes get caught up in "needing" longer focal lengths when much can be done with 400 mm or less focal lengths. The biggest difference I am noticing is that the reach helps with AF. I went back and tested the similar shots where I had trouble with the 100-400L and 150-600 @400 had similar focus issues.
• I am pleased with the IQ coming off the 150-600S. It is sharper than my 100-400L but not as sharp at the 70-200 II. Generally, the bokeh is pleasing. There are a few issues, but generally good.
• No issues to report with AF. Very good thus far.
• The OS is legit 2-2.5 stops (I've had a few sharp photos taken at 600 mm 1/100).
• Size weight. It is in an odd range. I am physically capable of hand holding it, even for extended periods of time. All of my shots have been hand held. I could go on hikes with it. But I would not necessarily enjoy the size and weight of the lens during those times. I am altering my thinking a bit to that this lens has crossed the line to join "Big Whites" that are typically going to be shot off of supports. It is a tweener, a bit small to "need" support but a bit big to just walk around with and enjoy it.

Thanks....Brant
