Lighting / Re: Compact Manual Flash?

Yes, that is what I thought @private wanted to suggest.

I am sorry, I do not know anymore than this. My knowledge goes to using two/three nikon flashes with canon camera. I attach one flash with the camera with a PC sync cable. I attach the other flash with another PC sync cable with a hotshoe mount (which has a pc sync port). I attach the third flash with one of the off camera flashes with another pc sync cable. So a quite complicated but inexpensive system works for me to take all my three flashes off camera.

Just use one 270EX II on an ETTL II cord to master for the other one via the camera menu. I thought I read the 270EX II could be a master if it was attached to a camera with the flash menus.

Hm..., I do not quite get it. Flash 1 is on the camera or attached via an ETTL cord. What do I do with Flash 2?

I think what @private wanted to mean is put the ETTL on the hotshoe. Then put flash 1 on the "immediate" hotshoe of the ETTL cord. The part of the ETTLII cord that fits into camera's hotshoe has another hotshoe on top of it to fit a flash - I am calling it the immediate hotshoe. Google for the picture of an ETTL II cord. The other end of the cord is still open, put flash 2 on that "corded" hotshoe of the ETTL cord.

If you are not afraid of the "dark" side, then older Nikon flashes are pretty good and affordable too in the second hand market. They are all manual (I mean can be controlled manually without the loss of any essential functionality with canon cameras). I myself use three of those (canon flashes like 430EX are too costly for me right now). I bought two preowned Nikon SB 28DX and one Nikon SB 28. Even SB 26 is supposed to be a good flash.

This new revolutionary technology traces its origin to the recent semi-proof of the existence of the God Particle. Now the camera can capture the light originating in any period of time. Does not matter if the time was long in the past or yet to come to pass.

Lenses / Re: What lenses should I take to India?

Take 24-105 and the 16-35.... With a fullframe sensor I guess you will be using the 24-105 most of the time. It will let you cover almost everything you want to cover. Many parts of South India (even with the reverse monsoon coming from the north) will be very dry during winter. So changing lenses on the street or location is not something I would do (I am Indian).

I hope all the glues will hold (not trying to be sarcastic).

A cheaper but almost as good as alternative to the Canon MK II is always very lucrative for photographically-non-earning enthusiasts like me...

OP, Seems you flushed out the liberals on this forum better than the toad in your photo.

Took me 5 minutes of painful eye squinting to be able to see the toad.

This could be one of those fun "what is it?" pics.

I am not liberal, not even American, just a photo enthusiast.

It might have been counted as a humor if it was properly executed.

I do not know who will win, but this photograph and the associated humor surely wouldn't......

OP you have a long way to go buddy. First if you are trying to take photograph of toads then make sure that you actually take good photos of that toad - not like paparazzi from behind shrubs and leaves. Second, the EF 85mm 1.8 is not that good a lens when used wide open at f/1.8. So learn to stop it down a little. Then learn that for portrait photography you need to make the subject the most visible and most distinct in the photograph - that is the main and most basic principle of portraiture. Then once you have learned all these stuff, and many more, and practiced a lot, and become a good portrait photographer only then and then only try your hand at political satire and caricature. Good luck on your steep learning curve.

By the way the comparable Sigma is pretty fantastic (QC issues aside) too.

     How do you think the new Tamron 70-200 2.8 zoom might compare to the venerable Canon Mk II?  I have a T1i and am currently using the Canon 135 f2 for indoor sports.
     Thanks.

The price will be definitely around half. But that does not mean image quality will be half. Quality control may be an issue. So if you are not an early adopter and wait till all the initial issues are sorted out then it should be good, very good in fact. For non-earning (from Photography) photographers I believe this will give good value for money. There will of course be some compromise at either the 70 mm end or the 200mm end. But, if their 70-300 is something to go by, this lens should also be pretty good for non-earning photogs (again emphasis on non-earning)

Comparing canon Mark II with this lens is like comparing the First Class of a plane with its economy class. If the passenger wants the facilities of First Class he/she has to be ready to pay for it. Otherwise, economy class will also take the passenger to the destination just fine.

Technical Support / AF Confirm. Chips and Camera Auto Focus System

« on: October 14, 2012, 08:11:49 PM »

I was thinking about this issue. What does the AF confirm chip do in conjunction with the camera AF system?

This is what I understand: When I am mounting an EF mount lens (from any manufacturer) on my canon camera, the processor of the lens lets the processor in the camera know, through the electrical contacts on the mount that a specific lens (focal length, max aperture, and lens ID) has been mounted on the camera. The programmable AF confirm chips also probably do the same thing (at least upto this point). Let's call it the lens id stage.

Now, when I am trying to Autofocus an EF lens, there is again an information exchange between the camera and the lens, which activates the lens AF motor to engage the focus elements of the lens (let's say we have chosen the center focus point only). When the split image on the focusing sensor at the base of the camera reaches a certain level of phase based difference/clarity (or whatever that is called technically) the AF point inside the viewfinder lights up and beeps. So my lens has acquired focus. The same thing happens while manually focusing the lens, except that the lens motor does not operate. Let's call it the focusing stage.

Now, then, what does the AF confirm chips do for non-EF lenses during this focusing stage? The chip has electrical contacts to complete the lens ID stage, but in the focusing stage it has nowhere to take the focusing information to take (as there is no focus motor in the lens). But still the focus points light up and beep when we gain focus. If the mount for the non-EF lens does not have any focus confirm chip then this beeping and lighting up does not happen. Does that mean, for the focus system inside the camera to work, we just need the camera to know that there is some "particular" lens mounted on the camera? So we just need to complete the lens ID stage. For non-chipped mounts the camera does not know that there is any lens at all on the camera and so the focus system keeps on "sleeping". Is that how the thing works? Any clarification is welcome.
