I don't know if this topic has been discussed but I am curious for answers so I will start this discussion. I moved this topic, I had it in the wrong forum section.

I am buying the Canon 300mm F2.8 II lens and I saw the Drop-in filter holder at B&H.

http://www.bhphotovideo.com/c/product/763737-REG/Canon_4773B001_52mm_Drop_in_Gelatin_Filter.html

Does anyone use this that owns a large Canon prime ? If yes, what filters do you use in the filter holder ?

I would like to use a 52mm graduated neutral density filter with the 300mm lens and I was talking to a guy at B&H and he said by using a graduated neutral density filter in the filter holder, I wouldn't get the same results as if I were using it on a lens that has screw in threads on the front of the lens. Do you think this is true ?

Has anyone used a gradated neutral density filter in this Drop-in filter holder ? If yes, how were the results ?

Thanks.

The amount of sunny days has been scarce here last months. So have the pretty wonderful sunsets, too.
Now we have to use what we have to employ our expensive photo gear.
So here's the new challenge: How ugly can a landscape be?
Here is my first attempt.

I had saved money for the Sigma 35f/1.4 A, but my tax return was higher than I expected, so I just ordered the Canon 24-70f/2.8 II instead!!! Wish me luck!

Over at Nikonrumors they posted this:

The Tokyo district court ordered Sigma to pay 1.5 billion JPY (around 14.5 million dollars) compensation to Nikon as a result of the patent infringement case for lenses with VR technology that was filed back in 2011. The lawsuit was based on six Sigma lenses with image stabilization technology. Initially Nikon was looking for a compensations of 12 billion yen (around 116 million dollars).

Here is the summary of the judgment:

"Nikon obtained the patent related to VR technology in 2002. The content of the patented invention relates to technology wherein a vibration detection device, which detects the amount of camera vibration at angles around photographic objects, prevents the influence of vibration of a motor for lens and thereby allows more accurate photo shots. Sigma affirms that the scope of the patented invention does not include any functions which reduce the influence of camera shake. However, Mr. Osuga, the Judge in Chief, states that the effects of the invention in Nikon’s specification is described as “it allows image blur to be reduced” and that the specification clears that it includes camera shake. Thus, Mr. Osuga stands for Nikon’s assertion. In addition, Mr. Osuga points out that image blur prevention system requires various control functions, and he states that this patented invention of Nikon’s should be rewarded based on the contribution of the patent to the defendant’s products, that is 15%. Therefore, the Tokyo District Court calculated profits earned by Sigma to be a maximum of 10.1 billion JPY, and found compensation of damages to be 15% of the profits of the accused products earned by Sigma."

I had purchased this lens from my local camera shop and was disappointed when I discovered that it would only focus on my 5D Mark III body. It would stall and quit trying to achieve focus on the 7D if I had focused on a near object, moved to focus on a far object and moved back to a nearer object. I took it back and tried 2 more copies of the lens but all had the same issue. That night after trying to solve it by carefully looking at the 7D setup, I realized that Custom Function III Option 4 was set to stop the lens drive if focus couldn't be achieved. I reset this to "1" and then went back to my camera dealer to try the Tamron again. Problem solved!

I've seen quite a few posts with similar problems on a couple different Canon bodies. I don't know if what I did would fix those issues, but it certainly took care of me problem. I am still just now trying the lens (I just got it today) but so far I am very happy with the focus and speed of focus.

I have an old 17-85 f4-5.6 IS USM that hasn't been used in about 4 years but is still in excellent condition. I've searched around briefly and the most I can get for it seems to be about $100-$150 (originally paid about $600 in 2008). What do other people do with lenses like this that will probably never get used again?

AlanF · Mar 10, 2014

We have an interesting thread of who would prefer a 600mm f/4 II versus 200-400mm f/4. Let's get down to the nitty gritty of who has actually bought or is in the process of buying one or more of the lenses discussed in the thread.

TrabimanUK · Mar 10, 2014

Hi guys,

I appreciate that this is a bit early, and there is still a chance the mythical 7DII might appear, but I'm starting to draw up a list of camera gear for my safari in September.

Last time we took a 7D, 2x60D and a 40D, coupled to a 100-400, 70-200 2.8II and a 24-70 each, giving us wide and reach and no need to change lenses.

We have recently purchased a 5D2, which was at a bargain price, so that is on the cards for taking this time, thogh is a bit slow for wildlife. We are looking to upgade some the kit this time (at least the 40D), and within the budget limit of about £1800, the following cameras fall out with good fps and at least good(ish) IQ:

1D IV
5D III
7D (mark 1)
70D

I know the 1DX is a killer, having played with one, but it is way unaffordable, and I have no intention to hire, as I can always sell the camera when get back to the UK (it's what we do with the Canon 100-400), so that it effectvely becomes a "free" hire.

So the question is, with a budget of £1800, what would be the best camera to go for, assumning tht the 7Dii doesn't appear, or should I go for e.g. 2 more 7D?

Huge thanks in advance,

Grant

pierceography · Mar 9, 2014

Hello all,
It's been awhile since I've posted here, but I have a fairly cliche question: What lenses do I take for a vacation? My wife and I are heading to Paris for a week in a few days, and I'm having a harder time than I would have thought picking the lenses I want to take with me. Here's what I've got:

Sigma 12-24mm
Canon TS-E 24mm f/3.5L II (*)
Canon 24-70mm f/2.8L II (*)
Sigma 35mm f/1.4
Sigma 50mm f/1.4
Canon 70-200mm f/2.8L II
Canon 85mm f/1.2L II
Canon 100mm f/2.8L (+)
Canon 135mm f/2L

(*) = Definitely taking, (+) = Not taking.

I'm fairly certain I'm going to take the 70-200mm for some people shots, as well as the 35mm for some evening photos after the sun has set. Otherwise, I'm pretty up in the air. I'm mostly interested in photographing the architecture and museums.

I'd like to keep it to six lenses, but I could conceivably take them all since my carryon will be a pelican case.

As a side question, I've already covered the red lines on all my lenses with gaffers tape. I realize I'm probably being a little paranoid, but does anyone have other suggestions for protecting my gear? I'm planning on using a messenger bag instead of a backpack and keeping it buckled.

Thanks, everyone!

** EDIT: I'll be shooting with my 5Dm3 **

milkrocks · Mar 9, 2014

Evening,

Thanks to everyone who provided advice about putting together a kit for a new baby. The gear I ended up with has been perfect thus far.

Current Kit:
6D & EOS 3
24-105L
Sigma 105 Macro (not as good as the canon but i picked up a used copy for $450 - well worth it)
50 F1.8, 40 2.8
EOS M, 18-55 & 22 f2

So I'm thinking I'll want a telephoto at some point for the 6D. In a perfect world I'd get a 70-200 F2.8L IS II and a 1.4X and 2X teleconverter kit. The $3000+ that this would cost however isn't possible now and won't be anytime soon.

The 70-200 F2.8L is part of the group buy on canonpricewatch for $1079. This seems like a great deal. The 70-200 F4L IS is also available at a great price, but I'm definitely less interested as I think if i was going to buy an F4+ tele zoom I'd either buy the 70-300 non-L to save cash or the 70-300L for its versatility and size.

Thoughts on the Non-IS 70-200 f2.8? Could it be a lens i have and use for a long time? I'm thinking I'd add at least the 1.4 at some point. This would primarily be for outdoor portrait situations, for when the kid starts running around a bit more and eventually for some youth sports action.

Thanks everyone,

Christian

se7en · Mar 9, 2014

For the sake of discussion, and pure speculation. I have frequently wondered if Sigma will be or is developing a 70-200mm f2.8 to compete with Canon's beloved L. I opted for the Sigma 35mm 1.4 A when it was just released over the Canon 35L and have been very impressed. I will likely buy the 50mm.

So, what do you think?

Steve Todd · Mar 9, 2014

Having used the back button AF method for several years, I thought I would try the dual back button feature made possible by the recent 2.0.3 firmware update. Until the new firmware update, I separated the AF Start function from the Shutter Button using the normal back button method. My focusing method was to have the AF-ON button set for AI-Servo AF. If I wanted to quickly lock the focus, I would simply focus using AI-Servo AF, release my thumb from the button, reframe the subject and shoot. I could have just switched between the two modes by pressing the AF Drive button on the top deck and use the Main Dial to switch between One-Shot AF and AI Servo AF. However, that just wasen't quick enough for my shoot style.

Prior to the new firmware update, you could program one of the programable buttons to toggle between AI-Servo AF and One-Shot AF. However, that required me to press the button set to toggle between the two AF modes (I used the Multi-function 2 button), with my second finger (middle finger) while using my thumb to press the AF-ON button to focus and my index finger (pointing finger) to release the shutter. That's not good either. Sure, I could have also left the shutter button to the default setting (AF and Metering Start-Shutter Release), but I still like separating those functions.

With the new firmware update, you can now program the AF-ON button to AI-Servo and the AE lock button to One-Shot AF. Once set, they are then dedicated to perform those functions when pressed and held in regardless of what is set on the top LCD panel. Having used this now for a few weeks, I find it the perfect match for my style of shooting.

To program these functions, use page 343 of the updated EOS-1D X Manual (downloadable from the Canon USA website). Simply use Custon Function 5 (Operation, Custom Controls) To make the programming changes to the buttons.

BTW, I programed the MF2 button for Spot AF and the DOF button for AE Lock, as I rarely use the DOF button anyway. I also program the M-Fn button next to the shutter button for the Viewfinder electronic level function.

Using the two back buttons for instant AF selection and activation, together with the Shutter button only used for metering and shutter release, add a great new operational capability to the already wonderful camera. I just wish I could setup my 1D4 to do the same!

I realize this was a rather lengthy explanation, but I know I like it spelled out fully when someone suggests a new method to me! Hope this helps! It is definitely worth trying!

mcragg9 · Mar 9, 2014

I am getting more into photography and am purchasing more gear. I have a T3i and a couple lenses that came with it which are nothing special. Plus the cheapest canon 40 mm. I am wondering if I should invest toward a flash, some external flashes and wireless receivers or save up for a nicer lens. Any advice or thoughts would be helpful.

Videoshooter · Mar 8, 2014

Hi All,

Just wanted to check if anybody has experienced the below problem before. I purchased the lens 2nd hand but the seller denies any knowledge of the problem (yeah, right!). I suspect a trip to Canon is in order for this lens but thought I'd run it by everyone here first in case there is some simple solution I've overlooked like shaking it vigorously or perhaps performing a rain dance.

My 24-105 f/4L is having problems with the aperture behaving erratically. When the camera is set to any aperture other than f/4, the iris will constantly change between several different settings. When zooming in, it gets darker (ie the lens doesn't compensate by widening the iris at longer focal lengths as it should to maintain the same aperture ratio. I'm not talking about a flicker, I'm talking about an obvious ~2-stop darkening of the image through the viewfinder) but when zooming out again it stays dark still.

The aperture setting in the camera is not reflective of what the lens iris is actually set to. Eg: the camera might read f/4 while the lens is actually at f/22. Changing the aperture does sometimes cause the iris to adjust, but only within the range of the camera - ie: if the camera reads f/5.6 but the lens is actually at f/22, I can only open up by one stop, because even though the lens is now only at f/16, the camera now thinks it is at it's limit of f/4 and so will not adjust it any further.

And as a precursor to all the usual generic responses, so far I've tried the following: same lens on multiple cameras, different lenses on same cameras, every combination of IS/AF on/off, cleaning the contacts on both the lens and cameras, camera powered by a fully-charged battery, in M mode, live view/movie mode and regular stills, and played around with the DOF preview button. Curiously, the DOF preview does not do anything but when using live-view AF via a half shutter press it does open the iris up to brighten the image, but only temporarlily. And yes, it is definitely the iris and not the shutterspeed/ISO messing up because a) it's in M mode with nothing on auto, and b) because I can see the iris blades flickering erratically through the front of the lens.

Thanks in advance for any help you can give me.... even if that help might be to tell me where my nearest Canon repair centre is!

One 6d owner got his 6d back from service with the new fw, but we don't know what's changed yet (see http://www.magiclantern.fm/forum/index.php?topic=5530.msg105576#msg105576).

Drizzt321 · Mar 7, 2014

So, since there's no real buy/sell forum, I'm putting a shout out here that I'm looking to buy a Pentax 645N. Preferably with 120 back & lens. Right now things are a bit pricey on ebay (along with the potential risk) and Keh.com doesn't have really much in the way of bodies & B&H has them, but at even a small premium over Ebay I'm still hoping to find something cheaper. Anyone?

cr1122 · Mar 7, 2014

Based on a thread at a popular macro photography forum, the unique Canon MP-E 65 1-5x macro lens is no longer manufactured and is not repairable long-term due to a lack of parts. A letter from Canon-UK is posted at this link, lending credibility to this rumor:

http://photography-on-the.net/forum/showthread.php?t=1362660

However, the various Canon regions do not seem to have the same information. However, Canon USA is apparently telling US customers that all is well and the lens continues in production. At least one of these sources of information is mistaken!

This is very confusing to us hard-core macro enthusiasts since many of us would purchase a spare MP-E 65 lens as a backup if the lens is truly no longer manufactured and is not repairable. I don't personally have the money to buy a $1050 backup lens unless it is really essential.

One longs for the truth about these issues. I wish Canon would issue an official statement worldwide so we'd know the truth with certainty. On the other hand, if they announced the lens being discontinued, I fear that the worldwide stock of new lenses would quickly disappear!

Does anyone know how to get an official statement out of Canon? Can the legendary Chuck Westfall help?

sagittariansrock · Mar 7, 2014

I have seen speculations and rumors on this forum since a year back regarding replacements to the 430EX II, but nothing has materialized. On the other hand, there are significant rebates on the 600EX-RT, which makes me wonder if Canon wants to abolish this second line of Speedlites altogether? What do you guys think? What are the relative merits of having a cheaper 600EX-RT vs a smaller 430EX replacement.

jeff92k7 · Mar 7, 2014

I was watching Top Gear's Sunday show (UK version, US airing is this coming Monday, I believe) and in one shot, I could very clearly see a typical Canon white lens attached to a pretty fancy rig. I couldn't get a good view of the camera body, but it appeared to be some sort of video camera body and not a typical DSLR body.

Does anyone here know what kind of camera that was? Is that typical of what they're using to film most of their segments with now?

I must say, I am very impressed with the very cinematic look of a couple of their recent stories. I noticed it a week or so ago, and then again in this episode - specifically where Richard is driving the Porsche Hybrid around the racetrac. Some of the shots look very, very nice. They look much nicer than I'm used to seeing on most TV shows. They almost look like film with the dynamic range in them, but I seriously doubt they are shooting film.

fluter · Mar 7, 2014

Hi guys,

I just got my brand-spanking-new 85L II in the mail. It works great, but there's a slight problem with the feel that I don't know how to react to. The focusing ring feels somewhat wobbly - every time I grab it, it shifts sideways, not catastrophically, but noticeably. I googled the issue and saw one review that talks about this wobble, but since there wasn't much else I could find, I'm looking for a second opinion here. Is this something that I should report to the seller and should I have them replace the lens? How many of you 85L users did this happen to?

Thank you very much.

<p>CPN has posted an article explaining the dual pixel technology upgrade for the <a href="http://www.bhphotovideo.com/c/product/889545-REG/Canon_EOS_C100_EF_Cinema.html/bi/2466/kbid/3296" target="_blank">Cinema EOS C100 camera</a>.</p>
<p><strong>How does dual pixel CMOS AF work?

</strong>Dual Pixel CMOS AF is a sensor-based, phase-detection autofocus (AF) technology that’s designed to provide smooth, high-performance continuous focus in movies. It is a unique, Canon-developed technology, ideal for fast and accurate autofocus, helping filmmakers to create stunning footage which maximises the creative options offered by fast lenses and shallow depth-of-field.</p>
<p>The EOS C100 camera with Dual Pixel CMOS AF technology features a CMOS sensor that consists of an array of pixels that each feature two separate photodiodes. By continuously comparing their outputs during AF Mode, phase-difference autofocus helps to ensure non-blurred images and smooth focus transitions even when the subjects and/or camera are moving. The new feature places a high priority on maintaining sharp focus while, providing a natural, smooth autofocus movement with selected Canon EF lenses that offer even smoother and quieter operation.</p>
<p>After this modification, the EOS C100 camera’s Continuous AF function active area represents 20% of the image vertically and 25% horizontally, yielding a very large, centrally located autofocus zone. The AF Lock mode allows you to set focus and hold it, allowing you to change framing while maintaining the original point of focus.</p>
