They are cheap.  I don't know of anyone who has tested them for distortion, but I doubt if they cause any big issues.  I've had a couple for several years, but don't use them, prefering B&W or Heliopan instead.
Canon certainly has plenty of glass expertise, the question is, do they use any of it in the filters or just rebrand tiffen?

Welcome.  Nice to see a new poster's first contribution be a photo rather than a whining troll.

Yet another supurb site for information.  You will see it quoted often around here.  Read it all, there is a huge amount of technical information there.

So contrast AF is more accurate than phase AF ?

Yes, but slower.  Phase detect uses a separate sensor, and if that sensor or the optics in front of it are misaligned relative to the image sensor, focus will be off (and that why there's AFMA - to correct that misalignment).  Contrast detect uses the image sensor itself to determine focus - nothing to misalign.
Contrast detect is not perfect, but so close that it doesn't matter.  Its just slow.  You can also chose the area you want to focus on by moving the white rectangle with your joystick (if there is one).
It is a good way to check your phase detect AF, if live AF is sharp and phase detect is not, you need a adjustment.  If neither are sharp, the issue might be more serious than a simple adjustment.

Third Party Manufacturers / Re: Recommend me a m42->EF adapter
« on: October 16, 2012, 04:35:15 PM »
The guy had a spare 'dump' adapter which works great. Since it's a Macro lens (55mm f/2. 8) , I probably won't really care about the AF confirm unless I'm actually shooting someone. Oh, and it came with an m42 bellows as well :)  Too bad it'll have to wait for a couple of weekends before I'll have time to start really playing with Macro.
That sounds good.   Just because 99 of 100 of the cheap chips work fine, does not mean its worth risking a $500 repair bill to save $20.
Its like the guys who got third party Li-on batteries and they did not catch fire.  Therefore, everyone is safe from buying them.  Tell that to the guys who died on the 747 brought down by Li-on batteries on fire.

I also prefer the twilight feel of the first (original) picture. 

The digital conundrum...because it can be changed, does that mean it SHOULD be changed?

Its up to the original shooter.  If he wants to use PP to change the image to look like what he remembers, he should.  The camera is merely guessing at the colors and other parameters based on mathematical algorithms and can be way off of what the scene actually looked like.  It is not necessary to keep a photo in its out of the camera state.

Lenses / Re: Can a refurbished lens be backordered?
« on: October 16, 2012, 04:22:25 PM »
Thanks for the quick reply. Last night a lot of refurbished lenses came back in stock, the 70-300L amongst them. Why should that one show up by mistake (happened twice already)? Isn't it a lot more likely that someone else just pulled the trigger and that is why it is out of stock again? This lense seems to be selling very well...

The 100-300mmL doews not sell quickly, even at 20% off, it did not sell out for 5 days.  When they add new stock, its not just one or two.

I'd take the lens to a local repair shop and have it cleaned.  If its not a expensive lens, just get another one.
Older FD lenses have sometimes been left in the trunk of a car, and the heat liquifies the grease, or the lubricant jusp plain separates and runs into everything.  This happens to all older lenses, its the lubricants available at the time.  Cleaning and relubing with a modern lube will fix it for another 50 years or more.

Hi all,

first post, driven by frustration... But I love this forum!

Did anyone receive their "backordered" refurbished lense, yet? I ordered mine (70-300L) during the 20% off sale and it is still on backorder even though it showed up as in stock twice already (10/8, and last night). Canon service keeps telling me they had no idea why it showed up and they would absolutely serve existing orders prior to putting items in the online store. I feel like they prefer selling it for the regular price than to me.

What is your experience?

Sometimes the lens shows up and then disappears right away when they recognize the error.  They have access to the stock inventory when you call, and if it shows zero, they can't send you one, no matter how much you want to make it read somethinng else.

You should be able to mount your camera on a tripod and look thru the viewfinder.  Thats without any elevated center column.  Never raise the center column, you might as well hand hold the camera, the shaking will be similar.

That means I don't have a choice but to buy
That would be fun. :D

What tripod do guys around 6 and more foot use? I guess most of them bend and so will I.

I have a couple of Benro C428 tripods.  I'm 6"2 and have to partially collapse the legs or its too high.  I happened to get them when B&H was closing them out for $180.  They still sell them imported from China on ebay.
They are 67 inches without the center column being up.  Thats probably good for someone 6-4 to 6-6.
Don't forget that the head and the QR plate and camera body add several inches to the height of the legs, so one that is 67 inches will be 72 inches or more, and your eye is 2 or more inches lower, so you do not need legs that extend 72 inches.  Look out for specs, they may include the center post all the way up. Benro specs both.

Also waiting for the new (440EX-RT) to pop up.  I'm sure its just a matter of time.   My guess is Canon wants to sell more 600s first or maybe its production capacity problems (6D production consuming all the resources...that damn 6D).
I doubt if they compete for resources at all.  If there is one coming out, it might be in January when they tend to introduce the less expensive equipment.  Just don't hold your breath.

Lenses / Re: Kenko TC and AF at F8
« on: October 15, 2012, 10:48:18 PM »'s definitely PRO DGX with the green (or was it blue) dot on the box (I don't have the box handy).  Actually. just remembered my wife has one, too, so I'll try hers, too, and see if it's any different.

I checked my box, its still laying here.  It has a blue dot.  That usually means some sort of rework or upgrade has been incorporated.
I do set the 100-400Lfocus distance limiter to the 6.5m - infinity setting and then the lens does not run thru its entire AF range.  That makes a huge difference in time to find focus.

While you retest on a stable tripod, don't raise the center column! I learnt the hard way about this no-no...
=1.  You can't be too stable for critical tests like this.  I get much better results in bright light and on concrete with my very heavy tripod and never extend the center column.  I could have added weight to the under hook, but my results were fine.
I'd not worry about a difference of 1 or 2 points unless the shape of the curve is very peaked.
Check the camera in good light tripod, and live AF.  If its not sharp, no amount of AFMA will fix that, the lens needs to be exchanged.

I'd Skip the PW.  Too many issues with a third party unit.  With the Canon 580EXII, for example, it has a range of 40 ft max, unless you put the weird RF sock on it or pay to have the flash modified.
Other triggers do not have the issue, but still seem to break with every new generation of camera bodies.  At some point, they will not update them any longer and you will have to buy new.
If you need a flash, get one, don't wait for a rumor to materialize.  Some have been waiting 7 years for a new 100-400L.  However, it currently had no real competition, its the best of its kind.
