1st Time Out In The Field With Sigma 150-600 Sport

The first decent day since the new lens arrived so I took myself off to Bossenden Woods, I have not made any AFMA adjustments to the Sigma as I wanted to see how it performed straight out of the box.
Compared to my Canon EF 500mm L IS the Sigma is a light weight, having said that it is very well built, I have changed the tripod mount from the one supplied with the sigma to funnily enough the one I had on my 500mm, Sunway Foto LF-C1 fits perfectly.
I changed it for two reasons:

1. The one supplied does not give sufficient clearance between the foot and lens barrel to carry the lens comfortably, there simply isn't enough clearance to get my dainty little mits in there without gloves on, with gloves no chance.
2.  The new foot is an Arca Swiss compatible so fits straight onto my Gimbal Head.

The Clearance between foot and barrel on the original mount is 15mm with the new foot it is 40mm which is more than enough and makes it easy to carry by the foot, (Sigma take note!!).

 First impressions go along way, the results I have from this Sigma lens on its first outing to me easily match my old Canon EF 500mm L IS output and as I said I have yet to set the AFMA so it can only improve a little !
The background bokeh doesn't look quite as nice as the Canon 500 but that is a small price to pay when saving £5000 or there abouts and there was a 2 stop difference in the pictures below so again the bokeh could improve when the same stop is used.

One might ask is it fair to compare a prime lens to a zoom lens, well in this case I think so as the zoom lens was purchased to replace the prime lens.

Next job is to check the AF accuracy but that will be another post.
