Software & Accessories / Re: problems after installing magic lantern

It should be pretty easy to test, just remove it and see if the problem still exists.
BTW, some of the third party grips have been noted to cause similar issues.

Occasionally, someone who is banned gets another IP, user name, and e-mail and starts posting again, however, a range of IP's can be banned as well.
I do not agree that a web site should just ignore abusers, spammers, etc because they occasionally come back with a new account.

Agreed.  Glad someone who knows about IP address filtering entered the room.
There are issues with IP filtering, I just do not mention them, enough trolls know how to work the system already without giving a tutorial.

IMHO, they do not ban enough users.  Some still post there that are banned here.
 

how long are you on the internet?   ;D
if someone is banned from a website he has a new account in 2 minutes.

it´s useless.

they should learn to live with criticism.
I started using the Internet in about 1985.  Long before there was a world wide web. , I There wasn't much but news groups and Gopher then, and we used Unix Commands on our Vax.
 When the world wide web became available in 1992, I was a early adopter.

I think I read this somewhere one time that some people set their cameras to 0 for sharpness to make it easier to tell if the shot is actually in focus or not on the LCD. Similar to how you get a focussing screen without the tiny micro lenses which make it look sharper than it really is. Is there any weight to this at all? Of course in post you can set it to whatever you actually want.
Never heard that one.  I use 5X or 10X and live view and am pretty confident in the focus adjustment.  However, except for special conditions, I have never been able to focus more accurately than a properly adjusted AF system.
I think that my vision might not be as good as some.

dpreview is a POS.


and they delete comments like mad.
say something negative at dpreview about dpreview and you have a good chance it will be removed and you be banned (for "trolling").

I am concerned about the quality of the lens testing, and, in particular, how it is presented.  The testing itself, is likely to be done carefully, but the most careful testing is not worth much if a lens is not properly adjusted, or is just exceptionaslly good (or bad).
This is a chance for them to hire a couple of good lens technicians who can adjust the lenses to remove and obvious QA issues so that we at least get values from a properly adjusted lens.  That does not answer the concern over sample variation though.

Lenses / Re: Canon EF 28-135 / EF-S 17-85 / EF-S 15-85
« on: October 02, 2012, 07:37:14 PM »
When Canon has the refurbished 15-85 on their 20% off sale like they did last weekend, its a bargain.  Buyers of 5D Mark II bodies are getting 24-105mm L lenses for $700.  That is also a steal.
I've had several 28-135 lenses that were kit lenses bought with new 40D's.  I never really liked them.  They are totally the wrong focal length to use as a standard zoom for a crop camera.
My 15-85 is much better than the 28-135.  As far as value to the buyer, that can be argued according to what you use it for.  The 17-55mm EF-S is the best, but you are not considering it.

Thats where a fast frame rate as well as focus stacking might be handy.  Focus stacking software can usually handle slight frame registration issues. 
I keep intending to try the feature in Magic Lantern.  I have used third party software with Breeze DSLR Capture to take images for focus stacking and it works well.

Lenses / Re: 85mm f1.8 or 100mm f2.0 ???
« on: October 02, 2012, 11:44:50 AM »
What you guys think about the  85mm f1.8 and 100mm f2.0 ???

THey are as close a pair of cousins as lenses get.  Do you want a little wider or a little narrower AoV?  If for APS-C, I'd get the 85/1.8.
Same lens formula and design, just different focal lengths.  Get the focal length you need.   Never select a lens because you think its the best, select one that you will use.

One of the big issues with mirror lenses is the background.  The subject may be sharp enough, but out of focus areas are horrible.  For astronomy, thats likely no issue, but otherwise, the 300mm f/4 might produce a nicer lookiing image.
600mm Sigma Mirror lens (one of the best)  Only the center is sharp, Notice the background!

 
500mm Nikon mirror lens (Also one of the best)  Notice the weird background)
 

 
 
300mm f/4L - None of the weird background stuff and very sharp.
 

 
 
 
 
300mm f/4L 100 % crop still sharp!

You are better off resizing to the max size you want displayed.  Monitors use about 96 dpi, so don't upload 300 dpi.

EOS Bodies / Re: 5D MKII Used?
« on: October 02, 2012, 11:17:36 AM »
I paid $1407 thru the Canon refurb program for a virtually ned camera that had under 300 actuations and a 90 day waranty.  The price went up $100, but I suspect it will drop back to $1400 or lower as Canon inventory of refurbs will build rapidly with new ones going for $1799.
I'd likely not want to save a few hundred dollars on a used one.  Just one trip to Canon for a minor repair would eatup most or all of the savings.  If the original batteries are used, they may soon need replacement, and if it comes with third party junk batteries, you will need to spend $100 on a good one to get reliability.
Make sure that the batteries are genuine Canon and that they have three bars when viewed in the battery window of setup.

One reason might be all the OS failures on the Sigma 120-300.  It seems to be carrying on the Sigma penchant for unreliable OS.  Everyone is hoping that the newer version beefs up some of the weak points.  I will not be wanting to buy one just to see.

For a crop camera, the Sigma is very good.  It falls down on FF a to where even the Canon 50mm f/1.4 beats it.
