Anyone else see a large disparity in the lens falloff measurements of the Sigma 35mm F/1.4 in the various reviews?

The Digital Picture lists a horrendous 3.5 stops on FF @ F/1.4 and 0.7 @ F/16

Others such as DxO say the vignetting is normal @ around 2 stop wide open.

The copy I had and returned was in the latter camp having average vignetting wide open but nothing that made me notice it.
The front focus problems, yes, but not the vignetting.

Maybe there is a wide variance in samples and the 3.5 is the worst of them?

HERE IS THE REVIEW GUYS... Hope u like them ..Please comment

Canon EOS 6d - A Practical Review

I am new here and have my first question

Is the 5D Mark iii a considerable enough upgrade from the 5D Mark ii?

Considering purchasing a 5D Mark iii and currently I own the 5D Mark ii. So basically I have the money and plenty of great lenses so I would like to upgrade to the 5D Mark iii but I wondering if it is worth the money and is it worth upgrading. I have my opinoins but I would like to hear others on this topic. Going from a 5D Mark ii to a 5D Mark iii will I really be gaining that much? And lastly is it worth it?

Thank you everyone

Coming from a 5Dc with an EE-S focusing screen, I was pretty disappointed that the 5D III didn't have a similar alternative. Doing some searching, it appeared that focusingscreen.com is currently the only option around. In short, a guy in Taiwan gets original Canon screens and modifies them - there are various microprism/grid/etc screens, but since I like the freedom to manual focus anywhere in the frame, I went with the S Type.

It arrived yesterday, meticulously packaged, and I got to work using their online instructions:
http://www.focusingscreen.com/work/5d3en.htm

As I was finishing the installation, I accidentally dropped one of these screws inside the camera, and as luck would have it, it dropped into the hole on the side of the mirror, where I can't see or reach it.


I turned the camera upside down, tilted it, shook it a bit - I could hear the screw rattling around for the first minute, and then it just stopped - I guess it got lodged somewhere.

Thankfully, the part that's held down with the 2 screws seems to be solid enough with just 1, but I'm not really happy about literally having a loose screw inside the camera, just waiting for the right time to break free and go exploring inside a lens... Maybe I should register screwloosephoto.com and capitalize on my mistake.

As for the focusing screen - it works great, same as my previous EE-S screen. To me, it makes the difference between trusting myself with manual focus through the viewfinder, and using it for emergencies only. A bit pricy, but totally worth it in the long term. Despite whatever reason Canon gave for not having swappable screens in the mk III (something about how it's a side effect of their new AF), the various AF modes continue working fine.

If anybody has any ideas on either getting the loose screw out (I was thinking of trying canned air) or at least finding a replacement for it, I'd be eager to hear it.

Hi Folks,

What methods do ya'll use to set the correct white balance for shooting video with your Canon 5D3?

External light meter? You can instictively know what Kelvin temp a room is? AutoWB?

Thanks in advance,

cayenne

A couple of friends and me want to do a video like the "DollarShaveClub" vid.

But how did they do it? A steady-cam and focus puller? A Dolly? What about the light and sound? What lens?

I shoot with a 5D mark III and 50mm.

Thanks

Sad news for it's staff and another blow to the uk high streets. With HMV sure to follow, its only going to be a few years until there is nothing left but coffee shops, eateries and clothes shops in city centres.
I just can't see the old business model of having a big 'bricks and mortar' presence working for a lot of companies now.

It got me thinking of these new 'Canon Stores', obviously it's a take on Apple stores and if it has a technical support area and a sensor cleaning/general servicing area, then cool right? Yeah, but how much revenue would come from people paying for the service as opposed to people using the warranty period? The only way I see them surviving the long run is if the in store prices can match popular online vendors. If a stores that sold a wide range of P&S's, Mirrorless, DSLR's, lenses and accessories from: Canon, Nikon, Sony, Olympus, Samsung and others has gone bust, then what chance does a store chance if they just sell Canon products at max RRP?

Aping Apple is just not a smart move for most companies. If you buy a new mac [not older models] from the Apple store it will cost you 'lets say' '£1,000', if you buy it from the online Apple store it will cost you £1,000, if you buy it from another vendor it will cost you '£1,000'. Therefore, you feel comfortable walking into the store and shelling out the cash, knowing that it's not cheaper elsewhere.
You can still shop around for deals with camera gear and I doubt these Canon stores will offer the best prices.

seems like every sensor maker improves it´s sensors except canon.

the new GH3 shows a big improvement and is as good as APS-C when it comes to noise, not to mention sonys great sensors .. and now RED.

and the 6D or 5D MK3?
marginal better ISO performance but lower spatial resolution and basically the same DR as a 4 year old camera.

With Canon finally making a mirrorless interchangeable lens camera makes you wonder when they will abandon SLRs all together. If I am not mistaken it took Canon 5 years to transition from FD mount to EF mount.

So what do you think? Will we be seeing our beloved gear become yesterday's news or a decades old survivor?

Most photographers, whether professional or hobbyist, are price conscious and want to get the best deal for their money. The best value for some means buying the most inexpensive item. For others it means the best quality no matter the price. I think that most of us fall somewhere in the middle, wanting to balance price with quality.

When it comes to OEM Canon accessories compared to third party options, I'm sure that some have found Canon accessories to be superior in quality, while others have found 3rd party equipment to be sufficient, if not equal in quality for much lower cost. There are also many horror stories of knock off equipment and bad service from third party manufacturers.

If anyone has a recommendation on a third party accessory (battery, grip, flash, caps, hoods, etc.) that you have found to be a good value and good quality, I'd like to hear it. If there are any ones that are better off avoided, I'd like to hear that too.

For you all curious people.

I have to put this up in 3 parts.

Enjoy!

Just got this as a backup body. paid 200. came with battery grip good deal?

Say I have about $2700 to spend. Two things that are of the utmost and equal importance to me:

• Having a full frame sensor with great high-ISO performance in a modern body
• Having the sharpest, widest aperture standard zoom on the market

It seems I cannot get both without spending more money. If I must compromise, should I sacrifice the sensor or the glass? Discuss.

Note: I don't care that the 24-70 is not wide on the T4i, as I would eventually sell the crop body and move up to full frame anyway. Just assume that image quality and light transmission are the most important features of the lenses to me.

looks like a very good lens

so i am looking for a speedlite for general use that woke hurt my wallet much.

Look at Youngnuo high end ETTL flash, 565, 568, which guide number is rated at 58, but i do see some post claiming a test shows similar output to the 430EXII.

so my question is, what do i get from the higher end Younguo that i don't get from the Canon? pros & cons? the 430EXII is roughly $250.

i understand the 565 has external battery pack option, which the 430 don't.

Camera would be 5Dc, currently with YN-465 which i don't put on top of my hotshoe.

If you have an Sony NEX camera and a bag of EF lenses this metabones adaptor makes some startling claims...
An EOS M killer?
Primarily for video use, why not stills too though?

I think the 40mm f2.8 pancake is the lens of the year due to its amazing value for money and versitility
what is your opinion on the best lens released in 2012? (let me know if I forgot any)

What would be your favorite lens? The one you'd say you took your best shots with?

So where do I start...I have been a longtime photographic amateur and owner of many Canon bodies/lenses. I have progressed up through 350, 450, 550 APS-C bodies until I finally got a 5D2. The 5D2 was working fine for indoor kid things like dance, choir and plays. It even covered soccer good enough. And then the girl starts playing volleyball. At that point the AF was done and beyond it's ability. While I was able to get some good shots I ended up throwing so many away that I started to get mad.

Gym lit soccer is just *terrible*. The lighting is trash and you really have to pull out the big gun lenses to stop the motion. I never could see getting a 70-200 f/2.8 and instead went for some primes. I switch between a 85 f/1.8 and the 135 f/2.0 and work around the court as I can.

After getting fed up with the 5D2 AF I waited until Christmas brought out sales for the 5D3. I was thinking about the 6D and its "super sensitive" center point but kept thinking that every body I went through was an upgrade, but a minor one at that. The 5D3 hit a low enough price point and I jumped on it.

I could not be happier. I had been reading about the AF and all its settings but was not prepared for everything in the menu. For a novice it's quite complicated...or can be. I spent a few days getting everything set in C1-3 for a few different setups that I thought might work. In the end I have gone with case 4, tracking turned down a notch. I have played with the expanded 4 AF points and pure all points. They both work well for 12 years olds. The only time I have OOF shots is because I was not aiming at the right thing. It's amazing to watch it track a player and just not let go.

But what has really turned me is the low light and metering ability. I was able to shoot my 70-200 f/4 , 1/640 and let the ISO do as it pleases. I ended up with shots at 12,800 that look great. If you have just enough light you can really quit using the heavy 2.8 zooms. The build quality is also much better and the CF door no longer feels like a toy. The silent mode is also amazing. When I go into a church or play I no longer have to feel bad for the family in front of me. It really is a game changer. And I sold my 5D2 in just 2 days!

So I had 1 problem. Out of 2 days I took ~1200 pictures. Just 1 of them resulted in the mirror seeming to get hung. The CF light just kept flashing and I saw "err" in the viewfinder. I either didn't notice or see the error number at the time...I have never seen an error in my cameras before.

These are just the ramblings of a photo idiot. I don't make a living with a camera, but I feel good for you guys that are shooting a 5D3....it feels special to me.

Here is the original article from January 4.

Very Interesting!

I'm getting a 6D this week, moving from my Canon XS. I'm 41 and am not a pro, but w/ 2 boys in scouts/soccer/choir/skiing and a lot of travel out West and in the Catskills I have an eclectic mix of photo opportunities, I don't want to miss anything.
I love the photo-journalistic style of photography. Over the last year, I've shot exclusively the Sigma 30mm f1.4 (50mm equivalent) on my crop camera to better learn this science/art. What I learned best was that I love shooting w/o a flash, but that the 50mm equiv. is often not wide enough, and that I need more iso, hence full frame.
I can do the 6D and starter lenses now to get a feel for what I really like in Ff, and can do a serious lens @ 1x per year thereafter. I'm thinking about starting w/ 6D and 40mm 2.8 STM, and Tamron 70-300 now, then moving to 70-40 and a 35mm f1.4 the next year. Followed in year 3 by a 70-200L 2.8 IS, year 4 w/ a 24-70 2.8. Somewhere in there getting a 135 F2 as well for indoor events.
What I could really use is some input on whether this is the right game-plan, or whether I should just get a 24-70 2.8 now, and fill in from there (only hesitation is IS)?
Thanks for any productive input from a first time poster on this great site!

Hello. I have just brought the canon speedlite 430ex ii and I am wanting to get the flash off camera. I know there are many ways of doing this but many of them are expensive. So can someone recommend a way of doing this at a decent price?

I have come across these two options, could someone also explain what the main differences are between the two of them and if they are any good?
