Hi everybody,

I have 7D + EF-S 10-22mm & i plan to buy the new EF 24-70 F/2.8L II USM, but im not sure this lens can give the top IQ on crop sensor like 7D.

Anybody 7D owner have this lens? maybe you can share your photo/review about this lens.

Thanks.

Hi. I was wondering if there were any rumblings about a Canon lens with similar specs?

Fyi: http://www.lensrentals.com/blog/2012/11/canon-24-70-mk-ii-variation

I think this is really interesting and deserves a post over here, because Roger comes to the conclusion that even though the data shows a large variation, the real world difference (well, with the current mp count on Canon) is very small - though shows when pixel peeping or comparing a "good" 24-70 against a "bad" 70-200 or vice versa.

I think most people realize there is sample variation. But this provides a nice illustration showing just how random a test report comparing just one copy of each lens can be. Don’t get me wrong; those reports are totally worthwhile.

But we have to be really careful splitting hairs with camera lenses. With 70 copies tested, I’m comfortable the average (mean) resolution of the 24-70 Mk II is slightly higher than the 70-200 f/2.8 IS II at 70mm. But that difference is much less than the sample variation

Click to expand...

I'm wondering how much the difference between lenses will show up when used on the upcoming high mp ff sensors, or when being (dual-)used on crop with higher pixel density?

I see BHPhoto and Amazon have the Canon SX260 for quite cheap at $199. Any thoughts on if that is an Xmas discount or inventory clearing price, preparing for an update?

I'm mostly curious if people think the successor in the ultra-zoom point-and-shoot category will just have some marginal improvements here and there ... say 14 or 16MP, or something more revolutionary [touch screen interface? controls revamped, appreciably bigger sensor/better ISO?].

At $199/small size, I'm ok buying/carrying it as a one-trick-pony ... 500mm zoom. Eventhough I'm pretty confident I'll feel the pictures will look very flat ... they're better than nothing. But I'd also be fine spending $300-$350 for something tangibly better.

Also, is it easy to do exposure compensation on this camera? I hate not having EV control on a dial. That and Aperture priority + easy to change f-stop are my two key control concerns.


[context: I often carry around my trusty G10. I have some mid-level Nikon SLRs/lenses but am looking at the D600 once the dust/oil issue is resolved ... I've been interested in something with more tele- than the G10 I can use casually ... small/cheap and can keep in the backpack permanently. It looks like it also uses the same battery as my PowerShot D10, another "one trick pony" ... that's also a benefit.]


Thanks for any thoughts or feedback.

I know this is an old topic but I was wondering if anyone has figured out a "fix" or anything. Maybe the soft images are the result of 18mp crammed into a small APS-C sensor. Sometimes I get tack sharp pictures, but usually I just get average pictures, not as sharp as would be expected. Ive played around with the micro adjustment and it didn't seem to help. Main lenses I use are the 18-135, 50mm 1.8, and 70-200 f4 is usm.

I took this picture a few weeks ago. I am using a 7D with a 70-200 II @ 70mm. 1/125, F/9, ISO 125

Here's a link to the color version: http://www.flickr.com/photos/s3r3n1ty/8156729456/#

BTW, I know the power lines take away from the photo, but there isn't much I can do about that. The spot where I took the pic is the only spot I can get it from without trespassing. How about the rest of the image? You like?

I don't want to invest in a lot of money in glass until I hear from other photographers. I do a lot of photography in the streets with my canon 5D mark ii ( got from eBay at a amazing price!) . I don't have any lens at the moment. I'm thinking about the 24-70 mark 2 or should I just go for some primes for my work? What do you recommend me?

The question is phrased with few options on purpose. Did you use a UV/haze protective filter on your EF 70-200 f2.8L IS (I or II) during its most recent use?

The aim here is to assess filter use among a narrowly defined group. I have avoided asking do you "generally" use filters as this can lead to subjective "calibration" of the response to suit attitudes that are deeply held but not practiced.

Because ultimately, actions speak louder than well thought out intentions. We all know the usual arguments for and against using UV filters that proponents use to support claims. Some fall back on specific lenses, where IQ may suffer vs. need to protect the front element, and needing it to complete weather sealing etc etc...it is frequently a slew of compromise explanations.

Let us try and gauge what we actually do in practice by taking a lens owned by good many, granted not all; and of 'relatively' decent $ value; with consensus on high IQ (that could arguably be degraded by a haze filter). To increase the sample size, either of the 2.8L IS versions are ok. This lens choice also hopefully ensures we aren't sampling exorbitant superteles or the lower price range lenses; but, something narrowly defined, commonly possessed, yet valuable.

In voting, please let only your actions speak. No "oh I could have" or "oh I wish I had" answers... No fudging...simple question: did you have it on during its most recent use?

If you had to start all over and have only one camera and one lens, what would it be?
I'm selling my:
5d mkii
24-70 2.8
70-200 2.8
and my 580ex
and using as little of that money to reduce my gear.

My family comes first and life isnt free, but i dont want to give up on photography, which has been my life since i was 17.

I know the overall "profit" ill make wont be a huge amount, but im 25 with a 9 month old and every penny counts right now.

I picked my current gear for landscapes and portraits. So that's what im looking to still be able to do. I probably cant have the best of both worlds, and something that does both, isnt likely to do it as well as what i have. but downgrading for money is looking to be my only option right now.

I am using 5D bodies at present & am looking at upgrading to the 5Dmk111 to provide a better viewing screen for checking exposures & better quality files with upgraded digi 5 processor ,even though my 3x 5D are working perfectly& I'm very happy with results.
Understanding that if I want to use a CF & SD card to record Full RAW files simultaneously for back up purposes for wedding photography & that the write speed is governed by the slower write speed of the SD card internal canon connection. Does anyone know the resulting frame rate available? & is it really aproblem if I'm not shooting multiple frames.
Also I'm considering purchasing a "quantum blade battery" for those bright Australian summer beach shoots which drain AA batteries quickly so the flash keeps fully charged while being used heavily for fill flash. I think I prefer the blade to clip on & cable styles so the camera remains unattached to me . I have heard the blade causes interference on the 5D & I heard rumors some folks have had flash failures/burnout due to the constant power causing overheating ext, any opinions or experiences would be much welcomed B4 I spend any money. Thanks Pete

I switched from Nikon to Canon (am I the only one doing this too LOL) last spring before wedding season and did some research online... Really dug the specs on the 5D3 as well as the 600EX-RT flash system.

I made the jump and sold my Nikon kit which consisted of a D3s, D700, 3x SB-900, 24-70G, 70-200VR1, 14-24, and 50 1.4 I ended up buying a 5D2, 5D3, 5x 600 EX-RT, 35L, 85 1.8, 135L, 70-200L IS1, and 17-40. I really haven't looked back since and shoot 85% of the time wielding two bodies with the 35L and 85 1.8.

Here is what I love about the 5D3

The 600 EX flash system has changed the way I shoot, at any point during the day of a wedding I will have at least one additional light firing off-camera. What a wonderful system. It works flawlessly in group mode when I want to light up a reception hall with 2-3 lights. My only gripe is that it doesn't work the same with the 5D2. Canon claims it is the processor, but I think they just want to sell more new cameras

The 5D3 files I have shot look indistinguishable if not slightly better than my old D3s as well, which is a blessing given the smaller size. The ability to shoot smaller RAW files has also been a charm. During the reception and other boring parts of the day, I shoot away in mRAW as very few wedding clients need a 22MP file. Despite a smaller file size, I like to perfect WB and exposure (which usually needs very little tweaking)...

The focusing system is incredible in my opinion. People complain about it being confusing, but once you sit down and really put all the different focusing patterns and modes into practice, I rarely get an OOF shot even with a prime at ~f/2. Granted my keeper rate is much higher with the 70-200 f/2.8 IS, but I think that is just a function of focus speed with primes vs zooms, not anything to do with the camera. I did notice the camera focused a little slower with the 600EX AF assist beam, so I did a little test. I have my DOF preview button set to switch between SERVO>ONESHOT when I hold it down. I noticed that the camera focused much faster in SERVO mode without the AF assist beam (which it doesn't use anyway) even in very dim lighting. Now even in ONE SHOT, I only use the AF assist beam when it is absolutely pitch black which is almost never these days since video guys always have their annoying video lights on heh. From my experience using zone focusing/tracking, the 5D3 tends to get "thrown off" by objects in the background much less than any of my Nikons, even the D3s.

Perhaps the one "awful" thing about the 5D3 is the dark AF points in low light. My Nikon cameras always had a red square and it made moving AF points around in low light a breeze. I have learned to adapt to how my 5D3 works in this regard, but I am hoping for a FW update to remedy this at some point. Not keeping my hopes up, but it would be nice.

As far as dynamic range, maybe my exposures are just really nicely lit because of how often I use the off camera flash system. I don't really ever need to push or pull my RAW files more than 1EV, so maybe I'm not seeing this lack of dynamic range so many people have complained about. There are certainly merits to having more dynamic range, heck I wouldn't argue against it. For landscape and studio shooters, I'm sure the D800 is a better choice, but right now the 5D3 is the best camera I have ever used for a wedding, right ahead of the D3s.

So overall I really have nothing bad to say about the 5D3. I view it as a baby D3s. I shot just over 35 weddings this past season and it took only a couple jobs (second shooting for another studio in April) to get fully accustomed to the Canon controls. I actually prefer how ISO is changed on Canon bodies and I never even have to take my eye away from the finder. Despite some minor quirks here and there, the overall value of the 600EX-RT system more than makes up for anything I could complain about.

Am I just oblivious to problems or a lot of people just suffering from "the grass is always greener" syndrome because of the rave reviews the D800 gets on websites like DXO?

I can't find any company with more than 500$ insurance on camera(electronic) stuff around the globe (I will travel to Europe) (theft,loss etc ).. I'm kind of worried about this because I will bring for about 6000$ in gear . Is there someone who can help me with this? Thank you
I'm from Quebec, Canada so I don't think a USA insurance can cover me..

My wife was lost for a gift to for me this Christmas, after a discussion over lunch, we went and ordered a Lensbaby Composer for me...

Any users out there, any tips for a beginner ?

I see that hardly anyone is posting in the macro topic. Thought I would liven it up with a few water drop shots from the last week.

Hi all, i am new to photography and this site. I have some questions that i would need some help with and hopefully some of you might be able to help me with. Please bear with me.

-am i right to say that the EF-S lenses do not work on the fullframe cameras
-What kind of difference are we talking about when we mount a regular EF lens as compared to a L lens on a fullframe camera
-Do the EF lenses maximize the full capacity of a fullframe camera as it does with the L lenses?
-How do i know what kind of third party manufacturer lens is compatible with a fullframe camera?

Thank you in advance!

Hi, I am putting together my upgraded camera kit for a trip to Antarctica and I have a 5D3 with 24-105 at the moment.

I feel this kit would be suitable: -

1. 5D3 with either Zeiss 21mm f2.8 OR Zeiss 18mm f3.5 OR PUSH IT TO Canon 14mm f2.8 ii ?
2. 100-400mm - maybe use a 7D for focal length?

Any thoughts at all from experienced people, especially Antarctica travellers/cold weather travellers but everyone's welcome

Thanks in advance.

Hi Folks,

I've seen some threads here recommending books on Flash/Lighting by Syl Arena.

I see two of them on Amazon:
Speedliter's Handbook: Learning to Craft Light with Canon Speedlites
http://www.amazon.com/Speedliters-Handbook-Learning-Craft-Speedlites/dp/032171105X/ref=wl_it_dp_o_pdT1_nS_nC?ie=UTF8&colid=3V9PVCC4ABLEP&coliid=I17E21C6P3BT9O

and

Lighting for Digital Photography: From Snapshots to Great Shots (Using Flash and Natural Light for Portrait, Still Life, Action, and Product Photography)
http://www.amazon.com/Lighting-Digital-Photography-Snapshots-Portrait/dp/0321832752/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=3V9PVCC4ABLEP&coliid=I5H7D2FEKICZ7

Which of these would be best to read starting off? I'm thinking before the Canon incentives go away, before EOY...I might get one of the 600EX-RT's.....so, thought I'd read up on flash and general lighting (wanting to do a family portrait while home for xmas)....I'd do a little readin up on this subject before heading home, and even while at home during the down times...

Any other books/resources you think might be better? Especially if specific to Canon equipment?

Thanks in advance,

Hello everyone,

This is my first time posting to the Canon Rumors forum, and I had an issue with a lens that I wanted to get some insight into and some advice on.

I purchased a refurbished EF-S 10-22mm wide angle lens a year or two ago from the Canon Refurbished store. I've been using the lens pretty regularly since I bought it. Recently I've noticed that the left side of pictures taken with the lens are really very soft, even stopped down (f 8 or 11 or so), and even when objects on the right sight of the picture (that are within the same plane) are sharper and in focus. I don't see the problem in earlier photos taken with the lens, and it does not require pixel-peeping to see the problem in the more recent pictures. I have never dropped the lens, and generally keep it stored in my camera bag, so if some sort of damage did occur I'm not sure what it would have been.

I know that wide angle lenses tend to lose resolution towards the edges and corners of the frame, but it is really the difference between the two sides of the images that leads me to believe it may be some sort of other problem.

Anyway, to get to the point, I was wondering: 1. What sort of defect or damage causes the sort of problem I'm describing? and 2. Has anyone sent a lens with a problem such as this to Canon and had it successfully repaired (and if so, do you recall about how much the repair cost)?

Thank you all for your help and advice!

Colleagues: I would request your advice on a 35 mm prime for Canon . I shoot 5DMkIII's and 1D Mark IV in challenging outdoor environments--dust, rain, sand--but am also a bug on sharp and contrasty lenses. Your thoughts on Canon's 35 L 1.4 vs. Sigma's 35 1.4? Thank you for your time.

My name is Maciej I not represent any company
I'm not spammer -

I wait for Canon company ( I need support engineer and tool ) I started in October

first 24 h test ( 6 oclock ,12:00 ,18:00, 24o)

first I made Earth's speed around sun 30 km/s ( 2.5 miles / sec ) = 30 000 000 mm /s

led move with Earth but light signal that "WAS SENT ! WAS ! " Not move with Earth around Sun

( light has zero mass or small mass )

Luminous Intensity is different when You make picture 30 km/s
compare to 220 km/s - Earth and Sun around galactica center

( the same led - the same energy but not the same distance in the same time )

dark filtre is very important


I would like to start cooperate with Canon ( my first picture I made Nikon 5000 but I'm open for better
test with Canon

On page I also show link to up sky automotive light system ( patent link )

( I also want to test my own new laser
system - we will be able use up sky signal in day )

all info about my discovery ( and why I call it discovery )

My Canon EOS 650D (T4i) with 18-135 mm 1:3.5-5.6 IS STM lens, a few months old, sometimes does not shut down - approximately once in 500 switchings off. The camera continues to show on the LCD screen what was there before the shutting down attempt. In the picture, look at the position of the video-on-off switch and at the LCD screen - the screen should show nothing.

In this mode, camera does not respond to controls. The way around is to pull out the battery. And it looks like in this mode the battery power is consumed at a high rate.

Does anybody know whether a firmware update is coming? There is none on Canon's web site.

Remember this lens? I was wondering how it fares against the current 70-200 f2.8L. Just curious about the image quality of this lens. Anyone had experience with this lens please chime in. I wish Canon made their teles black >_<
