Microfocus adjustment: driving me crazy

Following your 'logic', the 40D also had this magically improved AF code. The 40D does not have MFA, yet it was introduced after Canon had released a camera with MFA.

See the logic in my posting.

If there were any I would.

The 40D isn't a rebel. It was introduced after Canon had developed MFA. These are the two conditions which, according to you, mean that the 60D must have a new, improved AF system. So, according to your 'logic' the same must apply to the 40D.

Just to last, but I wish they put a MFA on all their DSLRs. I have a T3i and saw a great deal in the sell forum but the user stated he had to MA on his camera to get it sharp. I don't want to take a chance on buying and then having to spend more moeny to send it off for calibration which would then make it the cost of new. So in some cases, having that feature would allow you to buy used lenses that others may not want, and it would mean that any used lens purchased would normally not need to be sent for calibration (just in case.)

Someone will have to have a huge pile of very convincing evidence to convince me otherwise.

So you want a huge pile of evidence to prove that what you are saying, without any evidence by the way, is not true? That just does not make any sense to me.

Just because it needed MFA on his camera does not mean it would on yours. Before passing up a good deal on the lens it may be worth your while to find out if the sellers other lens had to have MFA. Atleast it would tell you if his body was way off and not the lens.

That may very well be true. So if it is still up for sale in a week because of the MA comment I will most likely contact the seller. But, the comment was a generality as well. Having the option available does expand options.

I agree with your statement, just trying to help you spend a little bit of your money.

For roughly the same price as the seller is asking, you can get one from Amazon, if the comment concerns you as much as it seems.

(assuming that is the lens you are looking at)

LOL it is, and that is one reason why I am hesitant to buy that used from amazon. I think those are returns that may need to have calibration done. 8 lenses that are all the same condition and same price. based on what I have heard about the lens, once you get a good copy it is fantastic, but getting to that point is a crap shoot.

You are better off buying a new one then, and sending it to Sigma for calibration, if you are that concerned. Much less stress, and you end up with a piece of paper you can send with your lens should you ever sell it, showing that it was calibrated by the manufacturer. I did that with my Sigma 50, and I am quite pleased with it on several cameras now.

Look around. Over 6 billion people on this planet believe is a god (lower case intentional) of some sort. They have even less evidence than I do. THAT does not make any sense. Since I can't prove their is a god, by your logic, there is NOT one. Take that up some of those 6 billion people. Talk about not making sense!

My point was you want a mountain of evidence, but do not have one shred yourself, Although it is funny that you are comparin religious beliefs to a 60d.

I have never needed the jack in my truck, but I am damn glad I have it, regardless of how much better my tire is made then the old model.

Point out the number of complaints about 60D needing MF with Canon lenses. I have 5 Canon lenses, including 2 macros, and haven't seen the need in any of them. I'm not a statistically significant set of data by myself, but you only seem to see those comments about MF from 50D and 7D owners, and those who use 3rd party lenses.

Not sure what your point is, I was questioning him needing a pile of evidence to change his mind, when he has no evidence himself.

Where did I say anything about 50d or 70d's? I have a 50d with Canon and 3 party lenses, never had to adjust any of them, but I like the fact that I could if I needed to. I guess my 50d got the new auto focus too.

I am one of those that swears by it. It is a tool provided by Canon for a reason. I also did a lot of reading on MFA and kind of came up with a way that is cheap, easy, and consistant. I had to adjust nearly all of my lenses. My L lenses not so much maybe 2 or 3 clicks. Other lenses really surprised me how much they were off. I have since dont many friends and family lenses all with positive results. I have attached a link to the post where I explain my method. Give it a try and let me know how it works for you.

I dont bother with it, if I have a lens thats not right it goes to canon.
