Who can clean and repair an old 28-70 2.8?

I have a 28-70 2.8 that is likely close to 15 years old. Looking through it now is almost like looking through fog.
It's still usable, and AF operates normally, but besides the fog issues I don't feel the images produced are tack sharp.
I would like to get it cleaned, checked, and calibrated and if possible be put back in serviceable condition.
Canon no longer offers support for this older model lens.
Anyone here know of a shop that can get this lens back to decent shape?

Replacement 400d - 650d vs. 6d

Hi everyone,
been a lurker for some time, great forum, would love to get your advice.

I've been shooting with a 400d (Rebel XTi?) since 2007 and have been happy enough with the size, handling and IQ outdoors. I have an EF 28-135 IS and an EF 50 1.4 and a Speed Lite 580.
I feel like it's time for an update. The things I'm missing most are low-light capabilities (I try not to go over ISO 400 and only use ISO 800 when REALLY needed), so I'm often stuck with my 50 mm lens indoors. I love that little lens, but on a crop body I would just need something wider. Would also love a better auto-focus since currently 90 % of the pics I take are of my toddler, second one on the way.

Now there are two possibilities I thought of:
Get a 6d, that way my lenses would be more wide-angle, I'd have amazing low light possibilities and an improved auto focus. Might want to add a 100 mm Macro (non-L) since I'd like a Macro lens anyways and I could use it for portraits as well. Cons: Size (quite happy only shlepping a Rebel around), price. Not sure how much better the auto focus would do. Otoh would focus in low light.

The alternative would be 650d/700d or 100d. Pro: Somewhat improved light sensitivity, the question is just how much compared to what I currently have. Also smaller size compared to a 6d. Would have money left over to buy new lenses. As an extreme example 600€ for a 650d plus 2100€ for a 24-70 2.8 Lii is the same as a 1800€ 6d plus a 900€ 24-105 4L :)

The other question would be whether it would make sense to still use my 28-135? I'm happy with the image quality but would it be the same on a FF sensor? (On the one hand bigger pixels, but on the other hand more vignetting?) The other question would be how much IQ I would give up on on a 6D. If not: What replacement to get? What "resolution" would that lense have? When I replace in a couple of years, would I have to buy new again?

Money is a factor, I would not be making any money with that equipment and in all likelihood won't in the future. The question is therefore more how much more light sensitivity, IQ and auto focus improvement I would get in a 6D, and whether it's worth the extra cash.

Thanks a lot

Can you use the ST-E3 or 600ex-rt triggering on a non-Canon camera?

Hi all. I generally shoot Canon, and own a kit with six 600s and an ST-E3. I have a job coming up in which I'll be shooting on Mamiya / Phase One, and am wondering if there's a way to use the radio triggering for the 600s. Any chance that the ST-E3 works to send out a manual "fire" command if it's on the off-brand hot shoe, or connected to pc cord?

Been searching and can't find an answer online. And ironically don't have an off-brand camera here to test with. Thanks for any insight. John

6D viewfinder too big ?

Hi

New to this forum :)

I just got my new canon 6d and I simply love it. Before, I had the canon XSi. One thing that I noticed is that when I look in the 6d viewfinder, it is very big. It nearly impossible to see it all. With the XSI, the visible square was smaller and I could easily see the image I was going to take. But with the 6d, I cant see the edges all at once. I have to move my head a bit from left t right to see it all. And if I waer my glasses, its even worst since my eyes are a bit farther.

Is is due to the full frame sensor? Anyone else noticed this ?

<p><strong>The lens that will never be…. it seems

</strong>Juza from <a href="http://www.juzaphoto.com" target="_blank">JuzaPhoto.com</a> had a chance to play with the upcoming, but yet-to-be-officially-announced EF 200-400 f/4L IS 1.4x. As with most previews, he was not allowed to post any images taken with the lens.</p>
<p>The interesting part of the article is at the end where he claims the lens will be available in mid 2014. That’s still a pretty long wait!</p>
<p><em>“One last thought is about price and availability. Canon has not said anything about price, but it won’t be cheap – my bet is between $9000 and $10000; availability is expected in mid 2014.

Seeking 1D(S) Mark III owners experience with using new battery LP-E4N

I recently bought the LP-E4N battery pack to replace the original (LP-E4) I got with the 1DS Mark III. According to Canon, this new battery pack is compatible with the 1D Mark III and IV cameras models:

http://www.learn.usa.canon.com/resources/articles/2013/lp-e4n_battery_pack.shtml

I would like to hear from people that are using this battery with these cameras if anyone have experienced the same issue that I am having. I have bought 2 LPE-4N's (new, manufactured in July 2012), and with both batteries the camera will occasionally lock-up. The power will stay on, but the camera is completely freezed and the only way to shot it down is to pull out the battery.When I the insert the battery again it will work as normal for a while. I have had never experienced a similar issue with the LP-E4.

The issue happens sporadically and appears to be completely erratic, at least I have no idea what causes it and I can't reproduce it at will. I have tried different shooting modes (one-shot and AI servo) and drive modes and even lenses.

I made a complete calibration and recharge of the batteries when I bought them on my LC-E4 charger. I am starting to wonder if issue with the new battery pack could somehow be caused by the higher capacity or safety changes to comply with the Japanese standards... At this point it seems to me that it must be a compatibility issue with the new battery, as I have never experienced any issue with my original LP-E4.

Thanks in advance for your feedback to anyone using this camera/battery combination!

<p><strong>MELVILLE, N.Y., April 22, 2013</strong> – Canon Inc., today announced that the company’s EOS line of interchangeable-lens digital cameras (Digital SLR and compact-system cameras) have consistently maintained the No. 1 share worldwide in terms of volume within the interchangeable-lens digital camera market for the 10-year period from 2003 to 2012.*1</p>
<p>In addition to interchangeable lenses, Canon also develops its own key components – the CMOS image sensors and image processors – employed in the company’s interchangeable-lens cameras, incorporating the most advanced of these technologies in its flagship EOS-1D series. By applying these technologies to other models as well, Canon has successfully created a powerful product lineup that effectively responds to the needs of a wide range of users, from professionals to entry-level users, which has enabled the company to maintain the top global share.</p>
<p>In 2003, the dawn of Digital SLR cameras, Canon introduced its breakthrough EOS Digital Rebel, a compact and lightweight user-friendly camera that set the stage for growth in the Digital SLR market while, at the same time, captured the top share of the global market. Since that time, Canon, in the company’s ongoing pursuit of high image quality, has launched a number of models targeting advanced-amateur users that offer among the highest levels of performance for their class, including the EOS 5D series, which paved the way for Digital SLR video recording.</p>
<p>In 2012, Canon celebrated the 25th anniversary of the introduction of the EOS camera system and marked its 10th consecutive year as the market’s world leader. During the year, Canon launched the compact-system EOS M, aimed at expanding the company’s entry-level user base, along with the EOS 6D, the world’s smallest and lightest*2 Digital SLR camera equipped with a 35mm full-frame CMOS sensor, which contributed to the growth of the advanced-amateur user segment.</p>
<p>This year, Canon introduced the EOS Rebel SL1, the world’s smallest and lightest*2 Digital SLR camera equipped with an APS-C-size sensor, bolstering its product lineup with a model befitting the industry’s top brand while targeting its 11th straight year as the world’s market leader.</p>
<p>With a history of producing cameras that dates back to the company’s founding in 1937, Canon will continue refining its diverse imaging technologies based on its core optical technologies, striving to produce exceptional and reliable lenses and cameras that cater to the varying needs of photographers-from first-time users to advanced amateurs and professionals-while contributing to expanding the photographic and video imaging culture.</p>

<p><strong>April 23, 2013

</strong>Normally, if you don’t see press invites about a week before, there’s nothing in the pipeline as far EOS goes. An example would be <a href="http://www.canonrumors.com/2013/03/announcements-on-march-22-2013-cr1/" target="_blank">these</a>. Lenses can sometimes be announced without any press event, as was the case with the EF 24-70 f/4L IS.</p>
<p>I do believe there is some truth to the delays <a href="http://www.canonrumors.com/2013/04/21mp-sensor-in-the-7d-mark-ii-cr1/" target="_blank">mentioned in this post</a>.</p>

5dmk3 freezes up

Only a week old, and after i take a photo sometimes it completely freezes. Even if i turn it off it still frozen. This happens straight after i take the picture and the preview is showed on LCD. On top of the camera screen it says " error " So my only solution is to take out the battery and back in.

Any thoughts?

9500 Printer showing Error code 9100 HELP HELP HELP

Does any one know what error code 9100 is & how to reset it on a canon 9500 printer. It took the paper in to the printer on the single sheet tray & started to print & then the blue on/off light flashed twice along with the orange light which flashes 10 or 12 times & then goes throughout the same sequence again. I've tried truing it off and unplugged it from the mains supply but it still does the same. The paper is locked down in the printer like its ready to print.
any ideas & help would be appreciated. THANKS

85mm f/1.2L II soft touch.

So I just picked up this lens. Um, it is sick.

My point of posting is to just bring up an aspect of the lens' design. The underside of the lens has like a soft-touch coating on it. I was just surprised when I first held it because no other Canon lens I have ever used had this finish. And I have never read about it in any reviews on the interwebs. Any other Canon lenses have this finish?

Also- is there a way to disable full-time manual focus on a 5DII?

I'll post some first shots from this new guy on the coming days. I have a feeling it is gonna stay stuck to one of my bodies for a long while :)

Canon 100-400mm L EF mount alignment question

Good afternoon, I have a question for the group regarding the EF mount on the 100-400mm L. I just received the lens on Saturday and tested it out this weekend. I am very impressed with the optical performance of the copy I received. Will enjoy having the extra reach on my 5D3.

However, one issue that I noticed immediately is the difficulty in getting the proper alignment when mounting this lens to the camera. For a pretty simple system (align the red dots, insert lens to mount, rotate clockwise) this lens required 5 or 6 attempts to get aligned and mounted each time I put it on the camera. The lens hardware seemed to want to go in the mount in a non-normal orientation. I've never experienced this with any other lens on this or previous cameras I've owned.

Looking at the bayonet mount, I could not detect anything different than my other lenses which would cause these alignment issues - but I'll look closer again today after work.

My question to the brain trust is this: Has anyone else had issues with the EF mount on this specific lens (or specifically with a 5D Mark iii)? I hate to send back a lens which is optically good if this is a universal attribute of this specific lens. However, I don't want to keep it if this is not a common issue and risk damaging the mount on my 5D3.

Thanks in advance for any experience you all can share.

What's in my bag (and what I should removed/condense).

Hey all,

First time poster here, but I have been a lurker for a while now. I have been dealing with the internal debate about my current lenses, and if I should try to condense my set into 2-3 lenses.

What I shoot:
-Portraits (mostly animal)
-Landscapes/nature
-Macro
-Street

My bag:

Canon 7d
Canon 70-200m F/4L IS
Canon 50mm F/1.8
Canon 40mm F/2.8 STM
Canon 10-22mm F3.5-4.5 USM

I mostly use my 70-200 and my 40, but it is nice to have the 10-22 around every once in a while. I have had a hard time getting results that I like with a wide-angle, but that is more than likely because I am just using it poorly.

My question is: sell the 50, 40 and 10-22 and put that toward a 24-70(or anything else in that range)??

I love my primes. I hate having so many lenses to choose from when I go out.

Thoughts?

TS-E 17mm or 24mm

I have been dreaming of a TS-E lens ever since I discovered they exist. I guess I am going to get one for my travel next month to Venice, Florence, Siena. I would probably opt for the 17mm version. So far I have been using my 16-35mm II when inside towns to do 'architecture' photography. What do you guys think 17mm or 24mm - both would be a bit cheeky...

Trouble mounting a new 24-70 II

Hi,

My new 24-70 II arrived today. However, I am less than pleased with the difficulty I am having mounting the lens. The lens seems to require more effort while mounting it onto both the 5D3 as well as the 6D. While turning the lens I am almost feel a slight grinding while turning the lens to lock it in.

I've never faced any such problem with any of my other lenses ... this doesn't seem to be a perfect fit for the cameras somehow. Anybody else face a similar problem? Suggestions ....

Thanks in advance ... J.R.

PS: I do have the option to return the lens if it doesn't work out. I'm kinda scared it'll mess up the bodies. I've just left it on the 5D3 for now (it is working fine).

Best smartphone for use with Canon DSLR?

I am about to "invest" in a new smartphone, and one of only reasons for going with a smartphone instead of a "phone-phone" is the aspect of using it to control my 5D mk3.
I am interested in both tethered and wireless options, but I am only finding sparse information pertaining to the options available to the different platforms ie. IOS, Android and windows phone 8
Any advice?
I am especially interested in finding out more about windows phone capabilities as I really like the Nokia Lumia (when actually using it as a phone) and find the apple to expensive :)
In the end, Android may be the way to go...

Panning shot - settings on 1dx case

Good day,

I have a question. Mainly I did some panning shots (car in motion type of thing) using 1dx + 24-70II. Overall it was ok...but really had to try more than once before getting something usable and focus speed was somehow not "responsive" (don't want to start a debate, but I was Nikon D4 ...and these are the kind of issues I never had).

Today I was at something like ISO 100; shutter speed: 1/40; aperture f16 (naturally depending on available light).
In terms of focus, I put it to servo (continuous) + 1 focus point + (+2 on sensitivity tracking).


What kind of settings would you guys recommend in terms of Focus point and Focus CASE ? and any other thing to watch out for ?.

thx

canon 5d mk3 what lens ?

Hi Guys,

Thank you for your attention.

I have a query. I have a canon 60D with Canon 10-22mm , Canon 50mm 1.8ii, Tamron 17-50 OS VC 2.8 and Canon 100mm 2.8 macro, i have recently purchased the Canon 5d mk 3. Now my ideal setup would be to get a 17-40mmL , 24-70L 2.8 ii, 70-200L 2.8 ii and possibly a 50mm 1.4 however all i can afford is the 1 lens for now. Which would be more ideal and i plan on shooting events , engagements , family portraits both indoors and outdoors but mainly people. could you advise on the next choice on lens as i am torn between the 24-70 or the 70-200. I know i have the middle range covered on the crop sensor however thinking of the 24-70 on a full frame could that be doubling up and just go with the 70-200 ? Your thoughts are much appreciated thank you !

Lens cleaning

I pulled my 100 mm f2.8 out and was trying some new ideas about work related macros and found little dots on the front lens. I used "breath" and a micro fiber but couldn't get them off. Must be more than 40 I can see and sprinkled liberally around my lens. The shot shows some of them in the red circles. I ordered Zeiss LIQUID CLEANER and that hasn't arrived yet. I've been known to stick that lens in close but I can't remember what could have caused the spots. None-the-less they're there. Should I send this off to canon to clean or try the zeiss cleaner first? I'm worried about removing the coatings on the lens with the cleaner. The cleaner is from B&H and it was recommended. Any thoughts about having canon cleaning it and secondly, using the zeiss cleaner? I've ordered a B+W 67mm XS-Pro Clear UV Haze with Multi-Resistant Nano Coating in the interim which was recommended on the forums.

Thanks for any input.

photographing paintings that have thick paint

I just moved this thread, because i had previously posted it in the wrong forum.

I am trying to build the ultimate setup for photographing a collection of art. Mostly large oil paintings (3feet x 4feet +/-) with significant impasto (thickly applied paint that has depth and 3D shape). There is also hand painted dinner and dessert plates that are glossy.

After much research and trail runs my list of goals are as follows:

1) Maximize sharpness
2) Maximize contrast
3) Maximize resolution
4) minimize vignetting
5) minimize distortion
6) minimize chromatic aberration
7) minimize out of focus fringing
8 ) minimize camera shake AND camera vibration
9) minimize glare,
10) reproduce accurate color
11) maximize uniformity

unknowns:
what is the best angles to put lights so that the paintings self shadowing looks the best (45, 45 copy table style is often recomended, but i think it produces unnatural looking shadows on the paint structure)
should lights be large or small ( soft shadows or sharp shadows )


so far this is the setup that I am thinking will produce the best results:

CAMERA: Canon 5DMK3 (currently owned) on a sturdy tripod or copy table
Set to mirror lockup and shooting raw

Lens: I have been using a Canon 50mm MK2 1.8 lens with great results but I am considering upgrading to 100mm 2.8L macro IS, or 100mm 2.8 macro, or 135mm 2.8L. Obviously in this situation a "flat field" prime lens will produce the best results. I am expecting something like a 5.6 or so aperture will be the best.

Color treatment: xrite color checker passport <- for color calibration (highly recommended). Use color calibration to get color correct, and don't do any other tweaks.

LIGHTING:
Currently this is the most nagging question for me. i am using lowelpro continuous lights which have a high color rendering index. I am experimenting with one or two set with a diffusion umbrella at about 45 degrees. And one or two lights without diffusion to produce sharper soft shadowing. But im worried that the shutter speed is just too long and also it produces uneven lighting and camera vibration is still present even on a tripod. I am thinking that possibly i could switch to using strobes witch would reduce vibration. I am also considering the wesscot grid flash modifier for creating highly directional and uniform lighting or moving the strobes very far away and not using any modifiers.

ALSO, i am wondering if i should be shooting in a black room or white room.

I am also doing what I can to reduce flare by looking at the histogram and goboing the lights just to make sure i am not getting any issues from off frame lights spilling into the lens.

Do any of the canon rumor members have any advice or experience to share for photographing paintings that have thick paint?
