chris i think its pretty obvious ,both shots are wide open at f6.3 ,i don't think theres a lens made that performs at optimum sharpness without being stopped down ,and also the fact that i shot wide open should tell you about the light on that particular day .there also shot hand held at close range so any problems will show up more .and also cropped in from the full image .
if i had used a tripod i would more than likely got the focus point dead on the birds eye ,but looking at the raw files shows it to be middle of the breast in both shots
I can't really see what your trying to say ,yes the linked one was taken at f8. but also at different times of the year and different light ,the shots from the other day where taken in dull sunlight and I played with the settings to see if it was sharp wide open if needed ,it worked for me .Do you know if this was taken wide open then, because this seems a lot sharper (albeit downsized more?) so that's why I wondered: https://www.talkphotography.co.uk/t...orts-owners-thread.577088/page-4#post-6778023

I personally love my lens it does a job that equals imho lenses that cost many thousands of pounds more .not much else to say but that it works for me
no problem ,as i said you have to take everything into account ,even my own stress levels and interest levels at the time of processing ,if my memory serves me rightly the linnet was shot using a bean bag support and the starling was hand held ,but saying that one was f8 and the other f6.3 .heres one from yesterday taken in gale force winds at a marine lake open to the full force of wind blowing in off the irish sea ,large whitecaps on the sea etc hand held shot once again .That's fine I just need to convince myself that I'll be happy with this lens and I'm basically using the images in this thread as my basis. Your previous shot was pin sharp and I was 100% convinced that I was going to get the lens. But then you posted the starling and I started to doubt my decision. I was just trying to acertain if for example the starlings were shot on a lower quality body and the previous shot was on a really high end body with many more MP. I wasn't critising your shot/technique so I apologise if it sounded like that.
Interestingly, when I posted about the starlings being slightly soft, I was viewing on my decent calibrated screen. I'm now viewing at home and it looks sharp and I can't see the softness I was seeing at work!. The strange thing is that it's the exact same screen! So basically ignore everything I said - I'm now 100% sure about this lens again!
oh yes most definitely ,although you do have to be a bit more careful with available light ,raising the iso levels is not a real issue ,its more flexible than the 400 prime ,focuses a lot closer ,is hand holdable on walkabout as long as you use a black rapid or similar shoulder strap ,the image stabiliser is to die for (check out shutter speeds on some of my pics )i very rarely use a tripod and its a hefty weight with a 1d3 so work it out for yourself .Hi jeff are you still happy with the sigma and are glad you passed on your canon 400mm 5.6 Prime

the main advantage of this lens is the USB hub as you can alter the parameters to suit how you shoot ,and as i have recently found out its still sharp even wide open
just tried it for you ,at just over 300mm ,there is short phase from f5 to f5.6 then f6.3I don't think anybody gave an answer to my previous question: at what focal length does the lens change from f5? Does it go directly from f5 to 6.3 or are there steps inbetween and if so, at what focal length does it change? Thanks

not yet managed to find one though I believe the think tank glass limousine will do the jobAny suggestions for a camera bag to hold this lens, mounted on a 5d2/7d and with the hood fitted ?
My tamrac 6x and kata 3n1 33pl are too short.
