Randy these aren't with a TC but with a D300 if you're shooting with a FX it'll be close.
nice work Eugene
I have the 150 and since I am now shooting it on my d3 I am considering the sigma 1.4 tc
FL of the 1.4TC would be like the D300. It was really good to work with, I could easily keep my distance from some bugs as well as get up close and personal.
I don't know how the TC will affect AF distance, unless you want to shoot at f2.8 you won't really miss it. I don't know enough to comment on loss of IQ due to the TC.
I know there was a fellow cafe member selling both his 150mm and 1.4 TC, I'm sure he'll see this thread and chime in.
But that being said I'm very interested in acquiring this lens again.
I'd get the TC, Randy. With your hand holding abilities I don't think you'll have any issues with the working distance.
I just purchased one from a Cafe member but the weather has been lousy so no good tripod work to show yet. But I gotta say that DOF sure gets shallow quickly with the TC mounted!
Here's a quick snap I made under poor light at 1/200s, hand-held, ISO 1600:
Randy - how about these?
AF or MF
how close were you ?
I was approximately 15" from her (lens to subject), bracing against the side of a tool shed.
I used AF but had to touch it up to get the focus point where I wanted... or at least tried to do so
Not much experience yet with the TC but I haven't noticed any AF issues such as increased hunting and the like. Just the inherently thinner DOF with the increased focal length when working close.
BTW, my TC is the older version, APO EX non-DG.
