just to let you know i,m still around lads ,although still shooting canon  i have just treated myself to a new lens the sigma 150-600mm sport ,what a real beast this is and totally unlike anything from the canon or nikon stable ,as well as being fully weather sealed its super sharp and via a little add on a USB dock you can fully program the lens to do exactly what you want  its arrived by blackfox wildlife and nature imaging, on Flickr |

BF, Do you call that a beast? Wait till you lay eyes on the (elder) Sigma 300-800, grin. http://www.sigmaphoto.com/product/300-800mm-f56-ex-dg-apo-hsm Regards, Gilbert |

Wating for the reviews on how the Tamron 150-600 compares with the Sigma 150-600. |

I´ve had a shot of that Sigma - was very impressed. It´s really sharp and can be hand held easily enough. |

Nice images. Which camera are you using these days? Looks suspiciously like a Canon. No problem with that just the controls dont suit me. |

That's a 1dmk3 its a 1.3 crop sensor only 10 MP but turns out a good image ,I also have a 70d but prefer the other one . The other beauty of that lens is that if at any time in the future I do decide to return to the nikon fold then sigma wiill (for a charge) change the mount ,so you don't lose your favourite lens by switching camera brands |

not done that much for a week or so due to bad weather ,but it did give me time to quietly sit back and analyze what i had been taking and to appraise various aspects ,first off i found that atmospherics played a large part in distortion at full range with the 70d especially over reflective surfaces i.e still water ,roads ,grass lands etc ,possibly due to the finer sensor to . with the 1D3 and its older 10mp sensor i was noticing that close shots were superb but over distance and with cropping detail was being lost even when stopped down . i threw these things around in my head for a week and came to the conclusion that the lens needed more fine tuning ,not just along the lines of M/A but the lens itself ,so yesterday i put in with the USB dock some new settings enabling different focal lengths of focus ,a finer degree of focus on the chosen point/s ,and a what sigma refer to as dynamic image stabiliser ,took it out today and to be honest the results were really good and although i might try tweaking more its definitely helped .the next one to test will be the 20mp 70d .

Nice shot Jeff, looks like its working well. JK. Horn Billies come out eggs! I'll get my coat. |

 I think that the Tamron Adaptall system was great but I guess with modern AF this wont work well as AF tolerances are pretty small. Hence the need for micro-adjustment feature even in factory made lenses. |

Great set of pictures looks like the Sigma is working very well! |

BF Your air pix of birds are spot on I wish I could do that! Just been photographing Godwits in E Anglia with my new Nikon 80-400 lens on ground spot on but keep missing focus when they are in air. The D810 locks on very fast but in air I just keep missing the focusing hot spot. Any tips would be super help please? |

things have actually moved on quiet a bit since my last post ,forgot about this TBH ,although i was getting decent enough shots with the lens i wasn't entirely happy with the end result pictures that much . so i actually sat down a few weeks back and went through loads over a couple of days trying to see what was wrong ,then i took the plunge and decided to fine tune it with the sigma USB DOCK well what a difference it was like someone had stuck a ferrari engine in a mini . there are various settings you can change one governs the way the o.s works /reacts and i have now set mine to DYNAMIC this helps to keep the focus point steady on the eye whilst hand holding and actually works ,the next thing i altered was the lens A/F and i changed this from fast focus to MAIN FOCUS POINT PRIORITY the two changes combined have turned this from a extremely good lens into a superior one a sample since changing is underneath  hard-nut ! by blackfox wildlife and nature imaging, on Flickrand another faster moving one  na ,na,na na by blackfox wildlife and nature imaging, on Flickr |
