Buff Einsteins can use any Balcar accessory?

I have to add that being able to run a head way down to that lowest setting with just a rocker switch is a powerful capability for location or even product photography. Food photos come to mind, real estate. With the big Normans (admittedly the old series 2000d packs) we were adding heads just to split power, or madly swapping connectors to move ratios around. Sometimes if an assistant moved too fast through that process there would be a loud bang and we'd have to pick the guy off the floor <grin>.

Ah, the good old days...

Poll: Most Wanted New Lenses of 2013.

RMC33 said:
I would LOVE to see the return of DO lenses, Got to use a 400 f/4 DO today and it was a joy, the contrast/color is a bit off but super easy to fix in post.
+100000 !!!!

I would be interested but this lens' IQ has been controversial.

Some say it is very good, some not (some determine 2003 as the make year that made the difference.

I remember correctly at the-digital-picture site the 400DO didn't take the teleconverters well (IQ wise).

+18 AFMA out of the box....return?

cervantes said:
Sorry jdramirez, that doesn't really make sense to me.

AFMA is used to correct for manufacturing tolerances. Tolerance means that nothing can be made to an exact value but it can be made for sure within certain boundaries. Canon knows these boundaries for their lenses and cameras. I believe when they allow AFMA to be set from -20 to +20 it should be enough to correct worst case scenario. I don't know that for sure but it would be logical from my point of view.

E.g: The maximum amount a camera can be "off" would be +/-10 and the maximum amount a lens can be "off" would be +/-10 so a correction of +/-20 would be sufficient.

In this case the lens is probably off -9 and the body -9 (so they are both around their extremes) but you can correct it by using +18. Due to the known tolerances your next body will not be off more than -10 so correction should always be possible.

That would be true if manufacturing process was perfect. It's not. Tolerances aren't absolute, to make them so would be prohibitively expensive. A common manufacturing practice is 3σ, which basically means ~3 out of every 1000 products that leave the factory will not fall within the tolerance range. Of course, if you get one of those you may not even notice it, but if you've got a lens on the other extreme, you might. If you do notice it (in time), Canon will fix it under warranty - doing so is cheaper than tighter adherence to tolerances in manufacturing.

It annoys me when camera phones try to take credit for professional level gear.

trojdor said:
the photoshopper got the reflection angle in the glass completely wrong on the second image (Sony). That's the kind of stuff that drives me crazy.

Set a product at the same angle on a reflective surface, and you'll find the reflection goes in the opposite direction they show. That's just lazy.

Hmm, I read it as the phone is sitting perpendicular to the surface, and the whole image is just tilted. Maybe because it didn't make sense any other way.

New Tilt-Shift Lenses in the Wild [CR2]

I'm not too fussed with a pair of new longer TS-e lenses. The original TS-e lenses were better, the longer they were. The worse one was the TS-e 24mm L, which optically was the weakest of the bunch. The TS-e 45 and 90 were / are optically very good. When Canon realeased the new TS-e 17L and TS-e 24IIL, they created two stellar lenses and turned the tide of Canon weak wide lenses. Sure, there were a lot of new improvements too, like newer coating and a far better movement system (which allows tilt and shift in every possible combination at a flick of a switch). But the longer lenses don't need the same optical improvement, they are already very good. Sure, they could do with an improvement in their movement mechanism and newer coatings but I question the diffenence that a double in retail price will do to the final images. Sure a newer lens will be better, but probably not observable in the final photographic output. I have a TS-e 45mm and it's a very low use lens for me and not one I use THAT often...in fact I don't know anyone who makes a lot of use for this niche lens.
I just get a feeling that Canon look at their lens portfolio and someone noticed that these two old lenses stick out a bit as old and legacy.

Who has pre-ordered or will order 200-400

I would get this lens to just have the ability to move within the 200-400 range without having to change lenses or switch between camera bodies. It's just something less to carry (or more) around at the football games. Just a thought but I'm probably going to stick with the 400mm 2.8 II since I've been saving up towards that goal. I'll try to rent the 200-400 when it becomes available before I make my purchase just to be sure. Or I'll see if I can borrow one from CPS for a test drive.

Urgent Help Please Elinchrom Flash lights

dont the Rx units have build in recievers to work with skyports?
so not sure why you are using seperate recievers

the elinchrom have 4 channels (selectable on the dip switches on the transmitter)
you need to make sure all recievers are on the same channel as the transmitter
might search youtube for a tutorial on how to change the channel for the built in recievers

to enable optical slaves make sure the button with the picture of the eye is on

The OP has titled the thread "SL1 sensor a step back?" ... clearly he is comparing the sensors here.

He is only comparing them in the title

Not really, the OP even goes on to say that -

What the heck? I hope this is not the 70D sensor.

my new 24-105

AZRAE1 said:
i have just bought myself a new 24-105mm lens and was thinking of buying the Lens Extension Tube EF 12 II and was wondering how much difference this will make etc; how close i can expect to get before the picture goes blurry im sorry if this is a stupid question im new to photography :-[

Extension tubes work just fine with that lens. I would recommend getting a set rather than just one so you have more choice. There are many cheap sets out there. As long as they work with AF they should be fine. But you will MF or live view focus much of the time anyway.

I seem to remember the max focus distance will be the focal length over the ET length.

40D vs. 6D AF

On face recognition - I had the 6D sitting on a bench as I played with the Wifi and there is absolutely no doubt it recognizes and refocuses on a face. I was moving my head all around and watching the camera's behavior on my computer monitor.

These camera discussions always represent opinions that are personal and I wouldn't push a 6D over a 5D3 unless money was an issue. However, I really wanted WiFi for remote shooting and the 5D3 didn't have it, so that finally made the difference for me. I was very apprehensive about the AF and decided that I was OK with recomposing at least until the next "has it all" crop camera hits the shelves. Getting the 24-70 F4, and the 300 F2.8 with both extenders was a killer on the pocket book! Also I didn't like the extra size and weight of the 5D3.

Todays shot 6D 300 2.8 II 2X III 1000th F5.6 ISO 1600 late evening

5D Mark III focus points off center

Martin said:
I had exactly the same problem and it was real. After three service visits they exchanged the mirror box. Atfer that repair the AF points' misplacement was corrected however since then I struggle with AF system. Since almost a year from purchase the camera is being serviced all the time without any good solution. My guaranty is almost over and the camera is like piece of crap. I can only suggest you to push the store to exchange it as probably any service will not fix that. I checked 3 canon services and every time if one thing was corrected the other one was not working properly. Right now center and left points are backfocusing and right points are focusing in opposite direction. One year of frustration without taking photos. Unfortunately IMHO if you think your AF points are misplaced-you are probably right. In my camera when I focused on the edge of any target it focused far away. And it was obvious that it happened only in one edge of focus point. It is normal that the real focus point has more area than its layout in viewfinder however not only in one direction. As I said-they fix this but camera probably lost all factory tolerances and now AF is just useless.

Sounds scary. I guess I'll have to discuss the issue once again with the service. They suggested that they'd move the viewfinder inside the body so that the points get aligned. To me this sounds like fixing a problem with another one and most likely doing more damage than anything else. If they mess up the AF, a serious problem is created to replace the possibly cosmetic one.

Now that I checked the issue again, I can also see (with the grid on) that the grid lines are longer on the right than on the left side of the frame. This tells me that the viewfinder might actually be in place but the indicated points are off center. ... Well, I don't know. I use cameras to take photos. Someone else can repair these things, but I hope that the someone also knows what he/she is doing while at it.
