Of the dozens of Canon EF lenses I've owned and tested since Canon introduced the MA feature, I have yet to find a single lens that has needed *any* MA adjustment.

Lucky you! May I ask...how have you confirmed that no adjustment was needed?

I find most Zoom Lenses need adjustments... (Near and Far) I used a LensAlign Target with Ruler but found it to be long and subjective to my analysis, I've since invested in a great program called Reikan Focal which takes the guess work and time out of aligning my lenses.

Guessing your alignment is not the way to go... there's a huge difference in clarity and crispness with just +1 .. also when using this software or a LensAlign Target, Canon suggest 50x the focal distance I find 25-30x gives better results. A good rule would also be to test 50x if you shoot far from your subject and 25x if you shoot close to your subject.

Lasers Can Damage Your Sensor

AAPhotog said:
This has been known about for quite sometime. I believe it has to be in liveview as well when the laser hits it.

Im just curious how canon would handle a warranty repair on such instance as there is certainly no warnings from them about the possibility of this happening. So would it be user area and no free fix/replacement from canon?

Yes, the topic is two years old, and someone just now resructed it. Maybe CR should lock all the old topics?

Choice of compact: OM-D em5 vs Sony RX 100

Besides the Canon G series, would you consider the S series?

Gman said:
Interesting reading. Especially as I am stuck in the need to get a new camera to travel with, within the month. The G11 has reached the end of it's useful life for me, there's no point in buying a G12 if there's a suspected G13/14 on the horizon. I'd kick myself silly if while waiting for the Gxx to come along I settled for the G12. So I have been looking around, like many I have a good dslr an Oly E410 with kit lenses and a great 12 -60mm Zuiko lens but it's too heavy for me to travel with (no silly remarks please).

The Canon EOS M wont be available until mid October when I will already be away. So what do I get in the meantime. No excuses that it's for the wife, it's for me. My wife never touches a camera unless I put it in her hands.

Anyway I dont want to travel with loads of lenses and so the RX100 looks very tasty to me too, I looked around for competition I couldn't see anything near it. Pity about the restricted zoom but it does seem to get good write ups around the groups. let's face it I wouldn't even be talking Sony if Canon got their act together and announced the G13 or 14 or whatever they or going to call it, bet they announce it at Photokina available........ xmas! Just like the EOS M announced recently not available till mid October, is that just to get us salivating or to make sure we dont wander off to the competition in the meantime?

By the way, I looked at an OMD body and compared it to my G11, it's fine until you start putting lenses on it, it will be the same with the EOS M but at least the OMD has a swivel screen (I think).

The one waiting the new version of 100-400 IS, investegation

I might have the funds from a tax refund around may/june of next year, if by then it's available, then for (almost*) sure I'll get one, if not, I'll have a tougher time deciding between the existing 100-400 which I have actually used and I'm in love with, and the 70-300 L which I have not used but I would believe might be an excellent choice given the advancement in technology when compared to the 100-400, but I certainly don't have any hardcore data to support such statement.

*almost in reference to a potentially obscene increment in price, like going from $1600 US to $3,000 US. In such case I would think, darn you Canon!

Powershot Gx? [CR1]

Curious how in the light of things that this topic was highjacked with the intro of the G1X which turned out not to be a Gx machine, bearing in mind that the original intention of the author of the subject heading was a CR1 on the introduction of a Gxx camera which so far has not materialised.
Just shows how long this subject has been simmering for, as a Google search will show.
Sorry for resurrecting this subject, just feeling let down and frustrated especially after two new Powershot models were promised this month neither of which turned out to be a Gxx model after all.
I wonder what happened to the source of the original CR1?

Autofocus of 50D/7D with 2x III TC and 70-200 2.8 IS II for sports

Nate said:
Which has better IQ the 7D+70-200+1.4 TC III or the 5D3+70-200+2 TC III?
How much faster would be the auto focus for the 7D setup?
The 7D has a higher pixel density and the 1.4 TC has better contrast and higher F-stop, so that would mean sharper pictures. I don't know about noise though but i guess after all it will be better than the 5D setup.

Focusing with the 1.4x should take two times as long as without TC and with the 2x it should take four times as long. (from heresay) I have never seen actual measurements on that though. Both setups still might be fast enough for you. If you can pre-focus it's no big issue but if you need focusing shot for shot in a series it might be just too slow.

Possible to connect 1Dx direct to laptop without needing a router/switch?

I had connected two of my computers with a crossover cable and no router. That was about 8 years back. If you have connected, try to PING 192.168.1.3 from your computer...

Does the cable work if you connect some other computer to your laptop?

These days 4 and 8 port switches are small. You can easily lug one. They are not expensive either...

Edit: is your wireless on? If so, is there an IP conflict with another 1.3? Turn wireless off...

24-105 damaged. Advice needed

Depends on how much you like that lens. If you want it repaired I'd only have Canon do this. Probably safer to unload for cheap and buy a refurbished from Canon or authorized dealer.

If it was mine I'd probably take it as an opportunity to buy something different. It's a nice enough lens optically but it's pretty flimsy for the money and for the "L" designation. Not saying that ANY lens would survive a drop in a fountain like this, but chances are that there are lenses that are more rugged and easier to repair. I'm thinking of the original 24-70. Me personally I'd probably chuck it and buy another nice prime instead. I don't trust any of this IS business to last for more than a few years.
