EOS Bodies / Re: NAB 2015: Cinema EOS C500 Mark II Confirmed

One area Canon can win is price. The Alexa Mini is Euro 32.5K body only, Viewfinder (Same as Amira) adds Euro 6K, Raw license (yes that right) another Euro 3K, want to go 4:3 for anamorphic that will be another license for Euro 3K all totalling Euro 44.5K. Oh and fully camera control is via the WDS which will set you back a further Euro 6K Arri certainly know how to skin their clients alive. Arri are over-pricing themselves on a sensor thats 3.2K

How many C500 MKII will that get you?
Lenses / Re: Canon ef-s 17-55mm 2.8 is usm GONE
« Last post by photonius on Today at 08:49:59 AM »
Has anybody seen that the 17-55 is completely gone from the product page from canon usa? I noticed yesterday that the price was missing and if you clicked on it that you got redirected to the home page. Now it's completely missing from their product page.

Well, as we know, CANON USA has its own idea what to sell and what not (see EOS-M).
Presumably they want to keep flogging the  EF 28-135 on crop instead of the 17-55, maybe more profitable...   ;D

Works great, IMO.  You need a stable tripod, and give it lots of light, ideally >10 EV (it reports light level) from an incandescent source or direct sun (not fluorescent or LED).
I have question regarding light source. 
Is one halogen lamp 150W is sufficient to properly illuminate  the target? I find it difficult to acquire incandescent lamp ( in my country of residence) with powerful bulb. Mostly LED or Fluorescent with max power 60W and those are not recommended for Test
I hope you don't mind asking me this question in your post gqllc007
Canon EF Zoom Lenses / Re: Canon EF 11-24mm f/4L USM

I've added a few more pics to

They look at distortion (the real sort, not just the effect of a wide rectilinear projection ;-) ) and flare.

Also the problem that sometimes comes as a surprise to landscape photographers not used to wide views when you move the horizon down - trees leaning inwards...

I'm not selling lenses, so I'm always going to include examples of what can go wrong if you're not careful, in any review. I've no interest in buying into the myth that just getting the latest wonderful new lens will massively improve your photos - that takes hard work and skill ;-)

However when i take a photo from my t4i, only the flash 600ex attached on my camera fires and not the Yongnuo YN-565EX.

Because the sync port on the 600EX is input only, it can't send a signal.

best solution ?

Hope this is okay to post here but I thought the audience of this thread would appreciate this . . .

Anyone got anything similar???  I've never seen anything quite like it.
Chromatic aberration and sharpness are worse in 50L. See this comparison with 60D and 1DS Mark iii, which should be very similar to the result of 70D and 6D.

How do I make a colorchecker passport photo if my Field Of View equals 1.20 mm x 0.90 mm?  :P

Hat doffed sir!  I've only seen one once myself and have nothing but a streak of blue and orange to show for the encounter!
Lenses / Re: Lens suggestions for trip to Grand Canyon
« Last post by danski0224 on Today at 07:31:26 AM »
I am going to Sedona and the Grand Canyon (south rim) next week and am trying to decide on which of my lenses to bring, and better yet, which lenses I should rent. I am very interested in landscape shots, dessert foliage shots, as well as trying out some night shots.  We will also be taking a helicopter tour over the canyon.

I have a 50D and the following lenses:
   > EF 28-135mm f/3.5-5.6 USM IS
   > EF 50mm f/1.4 USM
   > EF 70-300mm f/4-5.6 USM IS

I love my 70-300 lens, which is great for wildlife shots; but not so great for wide landscapes. While the 28-135 kit lens is ok, I think I want something wider.  I was thinking about renting the EF 16-35 or the EF 24-70, as well as the EF-S 10-22.  Any thoughts or suggestions? 

Also, would any of these lenses also be good for night landscapes or should I be renting another lens for that? 

I really appreciate any suggestions you might have on what lenses would be best to bring on this trip.


Good thing you didn't wait until next week to ask.... :)

When I took a van tour of the Grand Canyon, my 16-35II was by far, the most used lens on the 7D that I had. 

I didn't own the 10-22.

My biggest regret for the trip was not taking more panoramics. At the distances of the Grand Canyon, a handheld panoramic stitch can work rather well. I tried one for grins and was disappointed that I didn't do more when that series turned out OK. If you attempt some panoramics, you have to keep the exposure for each shot the same and turn off the autofocus (or do back-button AF lock so the shutter half press doesn't change the focus).

Many measurebators poo-poo the 16-35II, but nothing else does what it can.

The 16-35 f/4 IS is supposed to be a stellar lens if the f/4 works for you.

A CPL filter would probably help to bring out the colors.

Your 50mm f/1.4 would be the obvious choice for night work.

If I'm not mistaken, the 50D and 7D share the same sensor. I was not particularly happy with the 7D output in less than very good light.

If you are open to renting gear, I'd look at the 70D or even better- a 6D, especially if this is one of those "once in a lifetime" trips. I would rent the camera before renting the 10-22.

The wide lenses are tempting, but trying to capture the field of view with the 10-22 isn't the same as putting together a stitch at say 35mm taken in portrait orientation.
