24-70 II Onion Ring Bokeh

Merry Christmas Everyone.

I've been using my 24-70 II since April. Love it to pieces. Never really paid much attention to the bokeh until I took some photos of the Christmas light. Very very prominent onion ring bokeh. First I thought it might be the filter, but the same thing happened when I took off the filter.

Any thoughts? Is it inherent with this lens design or something is wrong with my specific copy?

Thanks!

ST-E3 RT + 600EX RT + 430EX II??

Hi all-

Just picked up a 600EX RT to go with the ST-E3 RT I had purchased earlier (I ran out of money hence getting the ST first). My question is: Can I mount the ST-E3 RT to my 5DIII and fire the 600EX RT via radio while having the 600 trigger the 430EX II optically?

My hope was to finally have the ability to do 2-light setups, but I can't seem to figure it out. Is there a workaround or should I sell the 430EX II and try to save up the cash to float another 600?

Thanks

200/2 IS Lust

Just wanted to get some opinions on whether to pick up one of these bad boys.

Recently presented with an opportunity to get one for 4450 which to me is a pretty good price. I already have an 85II, 135, and 70-200II which I am happy with for covering all my portraiture needs. However, having a slight case of GAS has me at least playing with the idea of buying the 200. Although I know I don't need it, just wondering if there is in fact something magical about it that I cannot duplicate with what I already have (assuming I don't specifically need F2 at 200mm).

Asahi S-M-C f/1.4 50mm

I saw a previous topic for the Helios 44m-2, so I figured there was some love for the glorious plethora of m42 lenses available, and this particular one - the Asahi S-M-C f/1.4 50mm is my joint favourite lens (along with the Helios!).

Having a Canon f/1.8 50mm and being largely unimpressed, despite it's sharpness, I got this Asahi lens from ebay. Unfortunately it hits the mirror on my 5dmk3, so I have a clear bit of plastic acting as a shim, and the m42 adaptor is now not coming off the lens.

I much prefer this 50mm over the Canon - to me, the sharpness is comparable (if not better), and the out of focus areas are way, way better than the Canon. The Asahi lens cost me about £20 more than the Canon from ebay, which having no autofocus I guess is some sort of testament to the quality of the optics.

Below are a couple of images, the first, Birnbeck pier at Weston-super-Mare, was taken at f/11, ISO 50 with an infrared filter, which resulted in an 8 minute exposure.

The second image was when I took the lens out for a test run at the new Severn crossing; I figured I'd get something to show off the bokeh.

Hopefully it may convince someone to try something different!

What is the deal with the front page? It keeps coming up messed up...

Is there someone messing with the CSS on the front / home page or something? It keeps coming up really borked at times...right now, looks like some sort of custom mobile interface, but I'm on a regular computer with browser....

Seems either someone is messing with the site that shouldn't be, or someone is going testing on the live site rather than a test one??

Two New 24-70's Coming in 2014? [CR1]

<strong>Two new 24-70 lenses coming in 2014?


</strong>We were told a long time ago that IS in the EF 24-70 f/2.8L II wasn’t yet dead, as prototypes do exist with image stabilization.</p>
<p>Canon chose to go the route of smaller size and lighter weight for the EF 24-70 f/2.8L II and created possibly the best performing standard zoom lens on the market.</p>
<p>We’ve been told that two new 24-70 type lenses with IS are a possibility and could appear in mid to late 2014. The first being a non-L 24-70 with IS and STM, along with a variable aperture. This lens would obviously be the least expensive lens of the 24-70 lineup.</p>
<p>The second would be an EF 24-70 f/2.8L IS, which would be larger and have optical performance that rivals the current non IS version. It wouldn’t be a replacement to the current lens, just a very expensive bigger brother.</p>
<p><strong>CR’s Take</strong>

I find all of this plausible, we were told a long time ago that Canon had basic plans in place for 4 different 24-70 lenses for various budgets and needs. If such a lens does appear, It’s going to cost A LOT!</p>
<p>This latest bit of information comes from parts unknown, so take it with a grain of salt.</p>

Vote for T1i, SL1 or 6D

I'm paralyzed with indecision on whether to keep my T1i, "upgrade" to an SL1 or upgrade to a 6D. My lenses are the 35 2.0 IS, 100 2.0 and 200 2.8II.
My primary doodie is indoor volleyball (my daughter's in 11th grade and is on a seriously crazy club team through to June), but I do it all and can really notice differences in image quality. For example - people say that zooms are as good as primes and I say "not" - I can tell and appreciate the difference.
Figured that if I were to go to full frame that I'd stick with my current lenses and add as appropriate (if even needed).
I do also very much appreciate simplicity and don't like articulating screens, don't use video and don't shoot Continuous. And I use LR4.
So, clearly, I'm unable to make a decision without anonymous guidance on the internet. I'm pleased with my T1i, but ready to be more pleased. My course is in your hands, I'll tally the responses and then do that.

How do you deal with lens reviews...

you read on the internet about lenses?

I am/was considering a UWA for my 5DmkII and have read reviews of the 17-40 (nice priced) and the 16-35II. Just for fun. I'm not a pro so spending my money is not based on earning money with the lenses.

When I read them, I get into doubts about to spend money on the lenses. Why.. well if I read the reviews on photozone, for both lenses they complain for ex. about corner sharpness. The 16-35 wide open should be also worse etc etc... There is always something worse.

Just thinking, how do you deal with...
believe...
what ever
those reviews?

teleconverters and resolving power

What does a teleconverter do for you if you wish to resolve fine details on a distant object?

The point that I am trying to make is that unless you have a really sharp lens, you are better without teleconverters.

My past experience is that using a crop body, if you have an ultra-sharp lens (like the series 2 big whites) a teleconverter will improve your resolving power, if you have a sharp lens (quality of 70-200F4) it is neutral, and if you have a soft lens it will hurt you.

The test is to capture photos of a small bird from 25 feet away. Since I can not get a bird to pose for me as I change lenses, I substituted a bird sized stuffed animal. All shots were cropped to the same portion of the bird's head and all images resampled to 500 pixels wide. unfortunately, I do not have a "big white" at home so that part of the test is left out... so the sharp lens used is a 70-200F4 and the soft lens is a Sigma 120-400F5.6. To make things interesting, a SX50 was thrown in as well.

The first pair of pictures is the SX50 at 50X zoom and then at 200X zoom (digital zoom enabled).
The second trio of pictures is of the 70-200 at 200mm, with a 1.4X teleconverter, and then with a 2X teleconverter. The third trio of pictures is of the 120-400 at 400mm, with a 1.4X teleconverter, and then with a 2X teleconverter.

In the first set, we find the image with digital zoom turned on is better than without. This came as a surprise to me as I had always assumed that digital zoom was an evil to be avoided......

In the second set, we see that the addition of the 1.4X teleconverter makes the image slightly better and that the 2X teleconverter makes things worse.

In the third set the teleconverters just degrade the images.

Something particularly important here is that a sharp 200mm lens provides more detail of that distant object than the soft 400mm lens.... but the most shocking conclusion is that a p/s camera (the SX50) can out-resolve both.

The last picture is the SX50 at 200X on the left and the 70-200 at 200mm on the right....

<strong>The future of the SX line?


</strong>Canon has patented a 100x zoom lens for compact cameras. It has a focal range of 3.6mm to 340mm. With the crop factor of 5.2 for a 1/2.3″ sensor, that’s about an 18mm-1768mm lens!</p>
<p>I’ve always thought 50x zoom wasnt enough in my bag, this is going to solve those issues! I expect to see a new SX series camera or two announced for CES 2014 in Las Vegas next month.</p>

Kilve Shoot

I did a shoot on Saturday at one of my landscape photography haunts. I've wanted to do some portraits there for a while. The lighting wasn't the best and the wind prevented off-camera flash, so I opted for natural light (even though the woodland shots needed ISO 6400). Here is a selection from the shoot.

Why does Focal tell users to use 1-Point instead of Spot AF?

I've been doing AFMA tests using Spot AF. I recently read through Focal's documentation (I haven't bought a license but am considering it) and it says that specifically for Canon bodies that testers should be using 1-Point AF and not Spot AF. I've always used Spot AF before because I somehow thought that the more precise focus area would be more appropriate for AFMA tests, but Focal's directions make me wonder if I've been doing it wrong this whole time. For example, if I use the LensAlign ruler, should I be shooting the target in 1-Point and not Spot?

If it's the case that using one is "correct" and using the other is "incorrect", I would greatly appreciate if someone could clarify me how the incorrect might might skew or even corrupt AFMA/focus tests.

As a related question, in the 5DM3 manual, the section titled "Manual Focusing" (p. 112), it says "with 61-point automatic selection, when the center AF point achieves focus, the focus light [dot] will light up." I'm a little confused as to what they are saying. When a lens is set on Manual focusing mode, Spot vs 1-Point vs Area vs etc. is irrelevant right? Perhaps I'm reading the sentence wrong but I'm wondering why they are mentioning "automatic selection" at all when talking about Manual focusing. Perhaps someone could clarify.

Thanks!

Best lightweight crop lens for SL1 & hiking

I have lots of photo gear. Lots of Canon bodies. Lots of lenses, mostly L. I have both Canon rugged P&S cams, the D10 and D20. (I took the D20 to Philmont in 2012 and carried it on the trail for 10 days.)

I'll go to Philmont again in 2014 and I want to try to take a DSLR this time for better pics and just suck up the added weight. I'll likely still take the D20 again, it was nice and handy to have hanging on my backpack strap at shoulder height while hiking. But when we are stopped at the camps or on side hikes, the DSLR would come out, that's where the best pictures happen anyway.

Just so you know, living on the trail for 10 days out of a pack, weight is the #1 concern. I've considered investing in a Pentax K-3 DSLR with a tough weather resistant general purpose lens. That would be around $1700 online. Not a deal breaker but it's spending close to $2000 if I ever bought a Pentax flash to own a whole other system. It would be more durable and less worry and who knows, I might love it so much that someday I would sell everything and just keep the Pentax. (Wow, I said that?!) But I digress..

I just bought the SL1 Rebel body for $349 (great price) figuring I would keep it in my pack while on the trail and use the D20 on my pack strap. The question is.....

Which lightweight lens to use so I only have to take one? I might take the 40mm pancake I have for low light and maybe a TC (if it fits the lens I choose) for more reach but in general, I figured I would take the DSLR+lens+simple strap as a unit, extra batteries and that's about it. I don't mind using a non-Canon lens. I don't mind just using the STM kit lens but I figured I would get everyone's opinion before I jumped. It's not a huge rush at this point.

While on the subject of hiking photography, check out this independent filmmaker's great movie all about Philmont. The movie trailer and documentary DVD is very well done. Gives me chills every time I see it! If you love the outdoors, you should love this. If you have young sons, join Boy Scouts. If you have tomboy daughters, join Venturing and go to Philmont if you can. Also, check out his website, he's done some great work!

<strong>What’s coming in 2014?


</strong>We’ve already been told that 2014 is going to be the “<a href="http://www.canonrumors.com/2013/11/more-mentions-of-2014-being-the-year-of-the-lens-cr1/" target="_blank">year of the lens</a>” from Canon. Some lenses are getting replaced, while there will be new ones added to the already impressive number of options.</p>
<p>Camera bodies are also going to be front and center. I have received word from a CR3 level source that there will in fact be a 7D Mark II equivalent. The prosumer APS-C camera will live on for at least another generation. The timeframe for an announcement wasn’t given.</p>
<p>More to come once we confirm a few more things.</p>
