Canon ST-E2 use as a Focus Assist only?

you can use the custom flash functions on the camera in menu and enable disable fireing the flash etc I think in there is the AF assist only option thats how it works for 580s anyway the 430 should be identical

Disable flash firing
Enable AF assist

Your camera will not consider the flash when it meters and your images will be exposed only for ambient light. AND, you'll get the benefit of the AF beam. This can be done with the 580EXII, and the ST-E2. Don't know about the 430EXII, since I've never tested it.

justsomedude - Are you saying that the ST-E2 can be used as a focus assist without a flash, and not impact the camera's metering? I can't figure out how to do this, the metering is always expecting that an off-camera flash will be firing.

Nevermind, I figured it out! On a 5d3, there is a "External Speedlite control" menu where you just have to set "Flash firing" to "disable" - with this the AF assist will still fire on an ST-E2 but metering will be unaffected. I should have thought to look in my manual first... :P

EF-S 18-135mm f/3.5-5.6 IS STM Lens availability ?????

EF-S 18-135mm f/3.5-5.6 IS STM Lens (NOW AVAILABLE)

Called Canon yesterday (7/19/12) inquiring about the T4i being bundled with the 18-135 STM lens. Every where I look, it's a "pre-order." The Canon rep said there's no word on when the two would be available together.

BUT, I did notice on the Canon store that the 18-135 STM lens was available to add to cart...so I asked the same rep, "is that real or backordered or....?" She said, no it's not currently available. I said it's on the Canon site right now. She said wait, let me check. And low and behold - she said they literally just got them in that day and yes they're in stock and available for order.

Price is $549.99. So if you need/want one, here's the direct link - http://www.usa.canon.com/cusa/professional/products/lenses/ef_lens_lineup/lens_standard_pro/ef_s_18_135mm_f_3_5_5_6_is_stm

Question...To UV or not to UV...that IS the question!

rahkshi007 said:
I am the one who use UV filter.. but i only use B+W and Hoya HD.. there are a few reason i use UV filter:
1) Those top quality filter has coating which is 10 times easier to clean than the glass of lens, even L lens.
2) I am using Crumpler 7 million on my shooting and traveling, it need to put 4 lens and 1 body and 1 flash: 24-70 2.8L, 17-40 f4L, 85mm f1.2II, 50mmf1.4 5dm2, 600ex-rt .. there is no more space for me to put those hoods, so most of the time i do not use hood..
3) with UV filter, i can switch my lens faster as i don use lens cap anymore, as those high quality filter does not scratch easily: all lens just squeeze into my bag without cap if i having photoshoot with model..

the disadvantage of UV filter : u lost just a little of sharpness and contrast even though it is B+W or Hoya HD.. only noticeable if u compare both image at 100% scale.

Hmmm, I don't think I've ever seen a pic where there was a loss of sharpness and contrast using a B+W UV filter.

GoPro HD Hero 2 for Dogs...Help!

Hi everyone! I'm a big reader, but rare poster, so apologies in advance if this is in the wrong part of the forums. I'm a Canon shooter, own a 5DMkII, 7D, and lots of lenses, which which I have captured some amazing shots of my beautiful German Shepherd and her puppies (she was pregnant when we rescued her). I've increasingly come to want to get a GoPro HD Hero 2, and experiment with getting shots from her POV in the park. I've seen videos online of some other dog owners who've done that, and think it's a really cool idea!

That being said, does anyone from this site have firsthand experience using the HD Hero 2 with animals? Any tips or suggestions? I'm thinking the 'Outdoor Edition' would make more sense to buy than the Motorsports or Surf Edition for my intended purposes...is that correct? Being that I don't own a car (NYC!) or surfboard, I probably wouldn't need those mounts. Would you recommend an accessory like the GoPro chest harness? The guy whose videos I've already seen on Vimeo used strong tape to hold the camera to his dog's harness, he didn't use the GoPro harness...but just cause he's the only one who posted a video, doesn't mean he's the only one who experimented, so I'd love to hear your thoughts!

I know the earlier GoPro models are fine for my intended use, but I'm pretty set on the HD Hero 2. Does anyone know if and when GoPro would release a successor? I don't want to get the HD Hero 2 only to hear the HD Hero 3 came out the next day :-)

What Ever Happened to the Major 5D3 Firmware Upgrade?

Another off-topic comments... sorry :P

The new version of EOS Utility includes the support for 7D firmware 2.0, but no mention of 5D3's firmware:-

"EOS Utility 2.11.4 Updater for Windows:
Supports EOS Kiss X6i / EOS REBEL T4i / EOS 650D, EOS 5D Mark III, EOS-1D X.
Supports EOS 7D Firmware Version 2.0.0. (For EOS 7D updated to Version 2.0.0, use EOS Utility 2.11.4 or later.)
The HDR (High Dynamic Range) function used during Remote Live View shooting has been added."

Gray vs Authorized Resellers

"Authorized Dealer" is the key. B&H sells gray markey, and since they are a authorized dealer, Canon will reluctantly (so far) repair it. Nikon is much tougher, and if you have noted that recently, Canon has been setting similar policies as Nikon. So they might start refusing Gray market from unathorized sellers any time.
Don't count on others ancedotal experiences as being true for any other than their own cases.

Should I get the 5dmk3 now or wait for possible unannounced 24-70mk2 kit

squarebox said:
Thanx for all the feedback. After hearing everyone's suggestions, I decided to get the 5dmk3 now with the 16-35L, the 24-105L, and with the savings and double rebate i'll get the 100L macro, or stretch and get the 70-200LIS.

What nailed it for me was that the 24-105L in the kit in the u.s. is 1/3 the cost of the 24-70mk2 here in japan. I could also probably sell the kit lens here in Japan for a profit. I was worried about the 24-70 being out in time for my trip to Hawaii in Oct..

You might need polarizer filter + nd 10stop filter for waterfall:

Upgrade 300 F4 IS with 300 f2.8 IS

IIIHobbs said:
It'e here and it's raining :-\

Looks like I will have to wait until the weekend to give a go. I tried a few test shots inside, but the 8' minimum focus distance was limiting my success a bit.

Not as big and head as I expected reading about it. The lens feels good in my hand, solid, I like it.

It is heavy, but that problem will be ignored once you test it out. I use one on a monopod for football and track and love it. Glad to hear you got it!

40mm Pancake Killed the 50mm??

This is why there is a 50macro, 100 macro and a 180 macro. They take different perspectives of the same objects

There is more - 35macro, 60macro, 70macro, 90macro ... 150macro was my choice and I'm still saving for MP-E 65 :).
I think that at 1:1 or higher magnifications the perspective is not that important (if at all). What matters is the lens working distance.

DOF is though - and the focal length impacts that when getting the 1:1

Lens to take to Kruger National Park South Africa

I was there last October.
If you are in the public part of the park, you need to have 300 or 400 mm at least (on a crop body) to capture
lions, rhino's and leopards.
If you are on a private lodge in kruger park, your 70-200 will do. These guys are driving you right next to the animals...
Really cool 8)
Had some lion cubs in about 15 metros distance and a leopard just 10 metros from the car !
Anyway, if you are into birds, better bring your big lenses (as usual....).

Regardless, what option you are going for, it is really worthwhile !

Canon 50D vs 7D

bklein61 said:
I currently own

Canon 50D
Canon 70-300L is
Sigma 17-50 2.8
Canon 50 1.8
Canon 580 EX II

I am thinking of upgrading to a Canon 7D. Part of the reason is for the much better focusing system for action shots of wildlife.

I am also wondering if there will be any significant improvement in ISO performance from the 50D, or would a better option would be to invest in glass.

Thank you for any advice.

Yes its worth the upgrade to the 7D, because you can down-sample the 18mp files and reduce the grain tremendously for decent sized prints.
