Don't sweat it over the cost of the 400 f/2.8isII. This one checks out at over $2 million.

Of course, it's a Leica...

so its been boggling my mind lately as to why there have not been more reviews of the new Sigma 50-150 2.8 OS.. this lens is some serious piece of kit that rivals the image quality of canons flag ship lens that cost more then twice as much.

i think for anyone who uses a crop cameras that this lens is a no brainier over the canon lens especially if you don't need the extra 50mm reach of the canon.

I recently sold my 70-200 2.8 is II and bought both the Sigma 50-150 2.8 OS and the Sigma 17-50 2.8 OS ... both which are fantastic lenses with basically L quality glass. This makes me think that sigma is finally starting to come into its own... it also shows how over priced the canon lenses really are... after selling the canon 70-200 and buying the Sigma lenses i was still left with close to $400 lol.

does anyone else have any other input on this matter?

Shot in available light on tripod with 7D and 100mm f/2.8L macro. ISO 100, f/32, 1.3 sec,

Ok All, I just got my 70-200 2.8 II and so far it's awesome! I had a chance to shoot a few portraits in natural light, when sun is almost setting and the lens just blows me away.

However, when I was indoor and had my aperture wide open at 2.8 and tried to shoot a couple zoomed in, the picture was focused on only 1 of the couple...the other person was out of focus.

I had my camera set at Evaluative Metering & chose Center Point focus. What settings should I set it if I desire to shoot at f2.8 but have all parties, be it a couple or a group of people, focused? What methods do you suggest?

Thanks for your input!

Just a question for owner's of this lens - I just got mine today from BHphoto and I noticed that the HIS system sounds kinda odd. Maybe I'm just not used to it - as most lenses I've owned haven't had IS/HIS - so it's just a new sound but it just seemed weird.

Turned it off too to make sure it wasn't the af system or anything else and it's only present when HIS is enabled.

Thanks!

Instead of buying a 600EX-RT flash + an ST-E3-RT transmitter, for my 5D Mark III, suppose I buy two 600EX-RT
The master will sit on the hotshoe, and the other will be used as a slave

Question
Apart from the price difference , size and weight penalty, what functions wil be missing from the flash, that I would be getting from a dedicated ST-E3-RT transmitter?

Thanks, and apologies if this was already discussed elsewhere

Hi,

I am still trying to master speedlight/night portrait photography, and ever since I upgraded to 5D3 with no built in flash, I am having difficulties using my 430EXII to get the correct exposure for night photography.

The usual setting would be trying to take pictures of people standing in front of a background scene at night. Whenever I try to use my speed light, the subject would turn out too bright and the background went completely dark.

I have read many forums and they all discussed different methods to achieve balance between nicely lit subject and visible background night scape.

So my question is, what is the correct settings for taking such pictures? I want to be able to use my 430EXII as my primary light for family vacation pictures, giving enough lightning to the subject as well as capturing the background night scape.

Any help is much appreciated, and yes, I am just starting to learn more about night photography with external flash

I was thinking I need upgrade to get higher iso on newer body.
I was going to get a refurbed, but is the extra 300+ worth it for 7d?
I have 17-40L and 70-200 2.8 is lenses.

I guess my action pictures will be of marching band in HS.
I am weary of 60d focusing if it behaves like the 10d focusing, where it is zoomed out,
it picks wrong object?

I have limited mobility and can handle moderate terrain and no strenuous or steep trails. I can probably handle a mile or two each way with several breaks. If anyone has any suggestions for good photo ops in Mt Rainier and Olympic National Parks as well as places to stay, I'd appreciate the help. If there is a better forum, please let me know. Is Mt St Helens a doable day trip from Mt Rainier or should I spend at least a day or so to do it justice? I'm planning on mid-July, early August 2013.

Given that I've definetely decided to buy the Canon 70-200 2.8, what would be the reason for me NOT to buy a 2x teleconverter to cover the up to 400mm range instead of Canon 100-400, apart from the slight aperture advantage at shorter range?

The flat lens eliminates optical aberrations such as the “fish-eye” effect that results from conventional wide-angle lenses. Astigmatism and coma aberrations also do not occur with the flat lens, so the resulting image or signal is completely accurate and does not require any complex corrective techniques.

It looks basically like a diffractive optical element taken to it's logical, nanoscale, conclusion. Very interesting.

Edit... I should probably note this isn't currently suitable for visible light (THz through near IR), so your 70-200/2.8 pancake will have to wait.

The title says it all.
I was delighted by the news of the revised 24/2.8 and 28/2.8 (except for price), but what about the 20/2.8 which is long past its sell-by-date, with its weak edge and corner performance.

Hi there,

I'm strongly considering buying a 5dii, but I'm wondering if it would be wise to wait until photokina and see if prize goes down.

What do you think? will the prize of the 5dii change if a new entry full frame is introduced?

Cheers

Does anyboby out there know where I can find a screen protector for a Canon 1DX camera?
Thanks.

I have been holding off on purchasing the 5d MkIII as I wanted the 24-70 f2.8 II as well (hopefully in a kit with the 5d), but the production delays for the lens are making things a bit interesting. I have a 65th Anniversary shoot (just family not for $) at the beginning of September and then a vacation to a spectacular nature and wildlife area afterwards. The price has dropped making it more appealing to purchase now. My dilemma is: should I get the 5d MkIII now or wait until the 24-70 II is available and with any luck bundled with the 5d? I currently have a 60d, EF-S 18-200mm kit lens (obviously doesn’t work on FF), 70-200 f/2.8 MkII, 100-400mm f/4.5-5.6L IS, 580 EXII Speedlight, EF 1.4 III extender. I can make do with this gear for September, but the 5d would be a nice addition, although with no FF lens to cover 24-70mm that is another problem. The 35mm f/1.4L would be one solution, but I was planning on the 24-70 before I moved into any primes. As well, the 35mm is due for an upgrade (although still highly regarded). Also there is the inexpensive 35mm f/2.

Any advice would be much appreciated.

Like title says, any low iso comparisons? Like side by side same image with both cameras? I've seen some comparisons in videos, but its hard to really appreciate quality in a youtube vid. I'm trying to decide if I should start lusting after the 1dx, or just be happy with my 5d3. I've always liked the idea of the 1d body style and durability, but i need some more info. Does the 1dx have more DR at iso 100? Is the banding any better?

I have discovered a focusing phenomenon with my 60d during a manual focus session with my 24-105L. Normally I use this lens on full auto but in manual focus a number of shots where out of focus despite being dead sharp in the view finder. I immediately thought of the infamous front or back focus problems associated with dslr's but after tests discovered a different kind of problem.

The following steps provide the basis of the test, best done with a medium telephoto lens.

1. Put camera on tripod and set Av for fastest aperture of lens. Set an object with fine detail or small text about 4 metres from the camera. Set lens to manual focus and move focus ring from a completely out of focus to the point of perfect focus on the object through view finder.

2. Take shot.

3. Do not touch the lens. Without moving anything, activate LiveView and activate the 10x screen zoom to see detail. In my tests this was slightly out of focus and the lens needed slightly re-focused to restore the sharp detail.

At face value this would suggest a front or back focus issue. However, when LiveView is then deactivated and the new focus checked through the viewfinder it was perfect and the resulting shot would be in perfect focus. It seemed as if the functioning of the mirror after LiveView somehow brought it back to a better seating. This is not the same as a consistent front or back focus problem. If the manual focus ring is then moved from one extreme to the other as in step 1 the problem would occur all over again for the next shot. This does not seem to happen for shots taken in auto focus.

I am convinced that extensive movement of the manual focus ring resulting in the movement of the internal structure of the lens causes tiny air pressure changes inside the camera which in turn cause microscopic movements of the mirror or screen out of position. I did tests with other lenses in manual focus and discovered the same effect. Has anyone else come across this with the 60d or other cameras in the range.

Hi,

I just bought a used lens (35L). It was in great condition, I checked pretty much everything and looked great. This is my fault that I did not check carefully but when I got home I found a tiny hair or dust inside of lens. I was not so happy. As I said I really should have been more careful, but at same time seller should have mentioned it.

Well, My questions is that how can I take care of this problem? Send it to Canon? How much would it cost? If you have suggestion or recommendation I truly appreciated.

Thanks!!

Camera Canada lists the canon 500mm f4 IS II at $8,999 vs others at $10,999, will accept pre-order. Has anyone bought high end equipment from this merchant before? Is the lens under warranty by Canon?

Hi, how likely is it, that Canon would release a 14-24 2.8 in the near future? Did Canon ever mention anything?
Cheers, Peter

anyone have any suggestions for good photo ops in Mt Rainier and Olympic National Parks as well as places to stay. If there is a better forum, please let me know. Is Mt St Helens a doable day trip from Mt Rainier or should I spend at least a day or so to do it justice? I'm planning on mid-July, early August 2013.

I forgot to add that my mobility is limited. I can handle moderate terrain but not strenuous climbing or steep trails.

Hi

I have a 40D-camera and the following lenses - Sigma 18-200 DC OS, Sigma 10-20DC HSM, Sigma 150-500 APPO DG HSM, Tamron 90/2.8.

My problem is that the noise-level is very high, even at ISO as low as 640.
I am thinking about an upgrade and are looking at 7D.

I have 2 questions :
Should wait a little longer for the 7D mark II (if it comes) or go for the current 7D?
or Should I start upgrading my lenses?

Most of my photos are macro-, landscape- or bird-photos.

I'm planning on going on a safari later this year and was wondering what lenses other people would take along. I plan to rent the 5d Mark III - I have tried it before and liked it, but am waiting on buying it until the "big megapixel" camera comes out.

I was wondering what people thought between the 100-400 zoom versus the 70-200 f2.8 with the extender. I figured the second option may be more versatile, but was wondering if using the teleconverter resulted in much less image quality at 400mm.

One last question - anyone have any thoughts about the 400mm DO lens?

Thanks.

Anyone have any tips that work for speeding up focus lock in low light situations (in my case wedding receptions)? I was hopeful that the 1DX would lock focus faster than the 5DMk3 bit alas it doesn't seem to. I love the camera after a half dozen weddings with it, and about 15 with the Mk3, but the extremely slow time to lock is killing me. Both the 5D1 and 5D2 did WAY better, which boggles my mind! If there are AF configurations I can try to speed things up I am eager to learn. Thanks all!
