Comment on Canon 60D, 1Ds MKIV and More by Chris Wawro

Let me add that I own a 1Ds MkII, 1Ds MkIII, & 5D MkII. Of the three, the 1Ds MkII has been problem free and the one I can count on to deliver sharp AF performance 99% of the time.

The 1Ds MkIII & 5D MkII have both been to Canon Factory Service for adjustments and service program.

My 1Ds MkII came out of the box screaming on Dec 29th 2004 and has been ever since, not a hiccup.

So, if one were to ask me what I feel is most important in the next 1Ds model, it would be a a glitch free AF system. The rest will be a bonus.

More resolution, more bells and whistles will get no one anywhere if the camera’s AF system works less than perfect. Bottom line.

If focus fails, all else fails.

That’s what I want to see, an AF system that locks on consistently and is tac sharp.

Comment on Sigma 120-400mm OS f/4.5-5.6 Lens Review by Neil Fiertel

This review is the first one of the 120-400 Sigma that totally agrees with my excellent results with the same combo. I noted falloff in the corners of course wide open but overall it is a fine piece of glass.When someone complains about a AF that is hunting or is slow…I think..hmm. likely the camera body. I also use the same Canon 5D mk2 and the combo is fantastic. I built from an old Vivitar flash grip a heavy but perfect anatomical device to fit on the tripod mount of this lens and can consistently shoot at 1/25th of a second at 400 mm using the OS. I am not exaggerating. It is worth finding one of those bakelite grips and stripping off the junk, make a threaded shaft for it and bolt it to this lens. It works a treat together if you have some muscles to hold the whole combo up, that is. In any case the only thing that I noted with this lens is that it is somewhat flare prone in back lighted circumstances such as very brightly lighted objects against a black background resulted in a pleasant dreamlike quality but obviously one must call this a flaw but one that is unavoidable with all the elements in this monster. It is a gem of a lens and my experience with it surpasses my less than enthusiastic tryout with the 100-400 Canon which is frankly outdated now.

After reading this review (and others) I purchased this tripod from Amazon.com. After free shipping, my total cost was under $45. It is very well made; I am amazed at the quality especially considering the low cost. I’m using a Canon SX10 now and may buy a DSLR at some point. This is my first “real” tripod and is just what I needed. I highly recommend it.

Nice features,i suspect it might beat the K7 in terms of high ISO noise,i might get one to go along with my K7 if this is the case.
