Bird of prey eyeball and megapixels

F
I went to a talk recently about birds of prey, and in it he had a model of a raptor eyeball. Unfortunately I can't find a picture online to show you, but the interesting thing was that the back of the eyeball had something like twice the surface area of the front. Imagine a truncated cone, with the top smaller part being the front eyeball and the base being the back, to give you an idea. The lecturer talked about how the reason for that was that they could pack so many more rods and cones on that eye, which the birds used to see prey from 3000 feet up. What he was talking about was evolutionary zoom.

Of course I related this to cameras. Whenever a rumor comes in for a big pixel camera somebody lectures us on how unnecessary that is, it would just clog our disks, and so forth. But with more pixels you can crop and zoom and still keep detail. With enough pixels, and a high enough resolution 50mm lens I can see a case where lugging around a lot of zooms diminishes.

Anyhow an improved autofocus from my 5DMKII, such as in the 5DMKIII is all I really need, but I'm hoping they do release a big megapixel camera, preferably in a 1D body. I'd buy it.

Leaked 6D Image?

Photoshopped from a 7D body? Not convincing that Canon will release both the 6D and 9D. Plus the two looks exactly the same, including lighting and shadows. However, notice the mic input has 5 pinholes instead of 4 on the 7D. The numbers '6' and '9' seems to blend quite well and real as well. Interesting...

edit: 9D pic is fake as noted that it is a joke by the poster at Weibo, discuss about the 6D pic instead

Canon 400/4 DO - why no upgrade?

With all the big Canons having been re-designed with improved optical performance and IS - the DO stands out for its neglect.

Have Canon come to the end of the line with this particular lens? Is DO a dead end anyway - even though Canon regularly leak hints of "possible" new DOs to come. Or is that all a sham to keep the 400/4 production line open?

Clearly optically inferior to the 300/2.8 nevertheless it is mechanically well made and a comparative lightweight and still has a good following.

Surprised that Nikon haven't introduced their own sharp 400/4 to fill the void.

(Apologies if this topic has already been covered)

Verifying USM / Af noise in Canon 24-105 L

candyman
I just bought a 24-105L
I notice a sound when pressing the shutter to AF. It is difficult to describe the sound but I don't hear this kind of sound on my 70-300L
Now I know the 70-300L is much newer and may have a more advanced mechanism.

I am just not used to this kind of sound and wonder if it is normal. I just like to hear your experiences before going back to the store.

Thanks

Lens recommendation to replace 18-135mm IS

Hey everyone,

My first post here, been reading and researching a lot and I really can't make up my mind, so I thought I'd throw the question out there and see what the response is.

I want to replace my kit 18-135mm IS lens with something that is better quality optically. Ever since I bought my 100mm L Macro, I've been spoiled by the sharpness, even for portraits and short telephoto shots.

I've been looking at lots of different lenses to upgrade to, since I will be selling the 18-135 shortly to help fund the new purchase. I've been looking at the following lenses:

1. Canon EF 24-105mm f/4L IS USM
2. Canon EF 17-40mm f/4L USM
3. Canon EF-S 15-85mm f/3.5-5.6 IS USM
4. Canon EF-S 17-55mm f/2.8 IS USM

Outside of macro shooting, which is so far my favorite, I want to get into street and short range photography, as well as landscape (not as often though). My current camera is a 60D, so I realize that the first option will be the tightest on the short end since it isn't so wide on a crop sensor. That's why I was looking at the other three. From your guys' experience, which would be the best all around lens? Or heck, should I be looking at prime lenses? I've been thinking of getting the new 40mm pancake just to see what a standard prime would be like since it's pretty cheap.

Help me out!

Thanks

Portrait of my nan, help!

C
Hey guys,

I know this is a bit cheesy but I have a huge family and we all love our nan so much. I want to get an amazing portrait of her sometime soon. Shes getting pretty old and I really want to capture what an amazing person she is. This is my first go with almost zero post processing.Hopefully I will have many more opportunities to re shoot, but what could I do better? Im going to her 87th bday party in 2 weeks :) Composition, posing, post processing our all things im thinking of. Im thinking i need a nicer back drop?

Craigslist 5D3 for 2900, good deal or buy 5d2 or 6d?

K
I have the cash, I want full frame very badly. I don't need that much camera as I'm not professional but 2900 for 7k shutter sounds like a good deal. There's a big camera sale coming this weekend locally I wonder if they might have 5d2s cheaper? Obviously the 5d3 is a heck of a lot more camera than 5d2(5d2 im sure would be amazing) and heck the rumored 6d might be more than 5d2(5d2 still prolly way awesome?). I just don't want to miss a potential good deal, unless you guys think prices on 5d3 an 5d2 may drop a bit after a potential 6d comes out? I have a 40d and 50d with a few efs lenses but I don't mind selling them, I would sell the 17-55 and 40d most likely. I can be very impulsive so I'm looking for grounded people to give me better advice. And if I go with 5d2 I want to buy the kit new. Thanks everyone I know I'm not the first one to make a thread like this!!

Lens Filters etc.

jasonmillard81
Good Morning,

I have the following lenses for my 60D:

Tokinon 17-55 (2.8)
Canon 50 (1.8)
Sigma 85 (1.4)

I was curious on a few things (i've used google but haven't found a centralized easy read on these questions):

1. What is the main purpose of filters etc. for lenses
2. Will adding a filter, etc., help bring clarity/sharpness to my focused images in video mode?
3. How best should they be applied (indoor vs. outdoor)

Best,

Jason

Basic Workflow?

jasonmillard81
Greetings all,

I am a 60D owner and use a Mac Laptop.

I use Magic Bullet Grinder to turn my files into ProRes LT (with 1080p proxie files) but not sure exactly how to use these files in FCPX.

There are some stunning videos done in post production with the same equipment.

Was curious on a simpler linear (step 1,2,3,4) process from importing video, converting it, using proxies, adding effects/corrections, exporting for both DVD & Vimeo/YouTube.

Thanks in advance (yes i used google but have yet to find a clear coherent and simple linear workflow process)

Best,

Jason

Canon 60D Video Images look SOFT!

jasonmillard81
Later this evening or tomorrow I will post footage showing that my video footage looks soft on my Canon 60D. Even compared to the same model the video looks soft relative to video clips on Vimeo & YouTube of other users.

I use:

Tokina 17-55 (2.8)
Canon 50 (1.8)
Sigma 85 (1.4)

Regardless of the lens i use my images seem "soft" and not "sharp/clear" I could try correcting it in post production but doubt that would be the issue.

thoughts/experiences/comments?

Best,

Jason! ;D

Canon EOS 6D in October? [CR1]

<strong>Not for Photokina?


</strong>Over at [<a href="http://www.northlight-images.co.uk/cameras/Canon_6d.html" target="_blank">NL</a>], they mention that the next full frame DSLR from Canon won’t come until October. That camera will be the EOS 6D, a smaller full frame camera that looks like the 7D at first glance. The camera is reported to come in at 22mp, the same as the current 5D Mark III.</p>
<p>As we’ve mentioned before, with the brisk sales of the <a href="http://www.bhphotovideo.com/c/product/583953-REG/Canon_2764B003_EOS_5D_Mark_II.html/BI/2466/kbid/3296" target="_blank">5D Mark II</a>, Canon is already the number 1 seller in the $2000 full frame camera market.</p>
<p>No DSLR for Photokina? It’s possible. The last time I was there, Canon was only showing off the 60D. A solid camera, but hardly a show stopper.</p>

5D MKII Shutter Sound

C
Not sure if this is normal but i picked up my new 5D2 yesterday, threw on my 70-200 after the battery had charged up and started taking pics.

The shutter sounds alot 'heavier' than the ones on my previous Canon camera's which is fine, but right at the end of process it almost sounds like the shutter is groaning if that makes any sense ? First noise when button is pressed is the clunk and immediately following that is the slight 'groan' ???

Is this how the shutter is supposed to sound or should I look at taking it back as the store offers a 14 day exchange period ?

First Time Flash Test

W
Hey all im renting the 600 EXRT for some group family shots this weekend so tested it out on my dog. this is all just on camera trying to bounce it different ways. Any tips would be great i really dont have much idea what i am doing. i have the 5d Mark iii. Also why would there not be a built in transmitter in the mark iii to the 600 ex? technology is definitely there to have the flash off the camera and release it without having to buy a $150 transmitter.
