Reviews / Re: Review - Sigma 24-105mm f/4 DG OS
« on: February 17, 2014, 10:21:36 AM »
For me the lens is just too heavy. I'm sure it would make an ideal lens for a lot of people though its just not really a travel lens, is it?

I also don't like the way it zooms, it looks weird.

I've only had my 24-105L for less than a year but it's already my most used lens. Yeah it has it's faults but damn that thing is just so useful. Kudos to Sigma for making a cracking lens though.

Exactly. A friend of mine *really* wanted to like it, but they wanted it as a sort of travel/backup kit lens. Too heavy for his work. I think there's a good reason that Canon is such a well travelled and sold lens: it meets a very good quality/weight/versatility balance.

Ugg. Focus shift.

Yeah, there's a term for that right? "Non-parfocal" but neither is the Canon... for what that's worth.

Why are there two threads for this story??

Compare this review with photozone's:
http://www.photozone.de/canon_eos_ff/864-sigma24105f4eos

All images from www.photozone.de

Maybe someone started one up unrelated to our review? Their own take?

charts *eyes glaze over*

But thanks for those, if I'm reading them right they confirm what I saw with my eyes, but with math.

Nobody tell my wife I posted high res photos of my dusty and messy bookshelf okay?  :-X
It can be worse: We can tell her that you posted high res photos of your dusty and messy bookshelf with a fresh new expensive lens  ;D

I'm surprised that there wasn't more difference on the samples posted in the review at f4. Maybe there is more obvious visual benefit at other focal lengths.

If people howl about the price difference between the 24-105 and 24-70 IS not being worth it I can't see that this would stack up for those people either when you can buy the Canon version so cheap.

I stick to what I thought when I first heard the rumour; this lens is targeted at Nikon / Sony users. However anything that keeps Canon on their toes is good for Canon users.

I agree, there wasn't a huge difference until I started pixel peeping. Corners were a big difference and that's even a highlight in Sigma's own marketing material. Without being too detail focused, the Sigma seemed to perform better at 50mm than the Canon, but I don't measure this stuff *too* much. At SRP, the Sigma is cheaper than the Canon, but we all know how to get the Canon for less these days... still, holding the Sigma mattered, it's a lovely lens even for a little bit more (but not a lot).

Why do people insist on posting images of bookshelves to demonstrate how "sharp" a lens is? There was not one detail in those images that was resolved differently by either lens, mainly due to the dearth of any high frequency detail that might show up resolution differences. If it wasn't for the distortion differences, I might have actually thought that they were samples from the same lens.

I think I'll wait for the results from Roger Cicala to decide whether the Sigma is a worthwhile upgrade. I would recommend that in future, you either do reviews properly or stop publishing this rubbish as CR's "official" review.

Out of 23 "reviews" this is the first and *only* time we posted photos of my dusty bookshelves. I certainly don't insist on it, or like it, but it does show difference of detail in the corners, vignetting and other real-world variables.

Roger is an incredible technical reviewer with all the right tools to measure and analyze lenses and I too look forward to his reviews and articles. I just pay less attention to the charts and more to how it works for me professionally. The final image is what matters to me and my clients.  I'm also open to hearing your take on what entails a "proper" review for my future rubbish.

Canon General / Re: Review: Canon Speedlite Transmitter ST-E3-RT
« on: January 30, 2014, 11:17:38 AM »
The YN-E3-RT from Yongnuo is every bit as good, cost over a hundred dollars less and gives you Group mode with pre 2012 Canon cameras, and adjustable M mode in five groups with almost any camera make, even you Fuji owners, plus a very useful AF assist lamp. So far the only thing I have found the Yongnuo doesn't do is work properly for pre 2012 cameras in Remote Shooting Mode, it doesn't fire the flashes but does release the shutter. But considering the positives far outweigh that one minor negative it is tough to not highly recommend the Yongnuo YN-E3-RT over the Canon ST-E3-RT.

I just picked up the YN-e3-RT as well and am working on my review. So far: I agree with you completely (And I didn't know about the remote shooting issue, so thanks for that tip). But, and you know this is the case too, some people will only *ever* buy proprietary first party gear, full warranty, local sellers etc. Thankfully the rest of us who are a bit more adventurous get the benefits.

I have the 600ex and the ST-E3…. its pretty good in close range and the config options of groups and so on are really useful.

However…. the range outside…. left me wanting.

Maybe I was expecting too much (ie. didn't read the bloody manual :D), but I was doing this beach shoot and was around 70 metres away from the flash. It would only fire every second time and lost connection a couple of times.

But apart from that it's great value!

I did the same thing, except at an indoor *huge* wedding venue and, well, I paid the price for not backing it up with pocket wizards for the range ;)

Canon General / Review: Canon Speedlite Transmitter ST-E3-RT
« on: January 30, 2014, 10:21:11 AM »

Bryan over at The-Digital-Picture has completed his review of the ST-E3-RT remote for Canon’s 600EX-RT flash system.


From his review:


“If you are a professional or serious amateur photographer and have the ability to choose the Canon’s radio wireless system for your uses, the decision to get one or more ST-E3-RT remote transmitters makes a lot of sense.”


Our reviewer, Justin, didn’t weigh in on the ST-E3-RT but did have high praise for Canon’s 600EX-RT system in our review. The bottom line is that Canon has a real winner with their RT system and all the components of it make for an incredible setup for anyone interested in off-camera flash.


You can purchase the ST-E3-RT from B&H on it’s own, from Adorama or save by buying it as part of a 2 speedlight, 1 ST-E3-RT set.

Lenses / Review: Canon EOS 100-400 f/4.5-5.6 L IS USM by DxO Mark
« on: January 29, 2014, 09:30:15 AM »

DxO labs has tested and reviewed the Canon EOS 100-400 f/4.5-5.6L IS.


From their review:


“Without doubt this lens is a popular model and it’s not difficult to see why. It has pretty good image quality throughout the range.”


Their own title to the review really sums it up “Still a good all-round choice.” It’s not a glowing review, but this has been a strong staple lens for pro photographers for many years. While an updated lens is certainly on the horizon, there is a lot of value left in this quality lens considering the pricier first-party alternatives. Of course, there are some choice third party lenses on the market too.

Canon General / Canon's Fiscal Year 2013 Financial Results Released
« on: January 29, 2014, 08:57:58 AM »

Canon’s a very large company, often we forget that consumer cameras and lenses are just a small fraction of that, to get an idea of the scope have a look at their financial results for 2013 (if you’re into looking at other people’s money.) Links are PDF’s



An excerpt on digital cameras:

“Within the Imaging System Business Unit, interchangeable-lens digital cameras maintained their top market share despite the challenging environment, which was marked by a drop in demand in Europe and China due to the economic downturn, although demand in Japan continued to expand. In particular, the EOS 5D Mark III and 70D advanced-amateur-model digital SLR cameras continued to realize healthy growth. Furthermore, in Japan, the new entry-level EOS Digital Rebel SL1 and T5i cameras proved popular. As for digital compact cameras, although total sales volume declined due to the market slowdown and the increasing popularity of smartphones, sales volume increased from the previous year for high-added-value models incorporating features that differentiate them from smartphones, such as large-size image sensors and models like the PowerShot SX50 HS and SX510 HS, which feature high-magnification zoom lenses.”


With almost no mention of mirrorless and it’s impact on the DSLR or compact market.

    EOS Bodies / Patent: Canon Curved Aperture Diaphragm
    « on: January 27, 2014, 09:56:24 AM »

    Here’s another patent filing picked up by egami:


    (translated)

    Patent Publication No. 2014-13363,2014-13365


  • Publication date 2014.1.23

  • Filing date 2012.6.6




  • Canon patents


  • The iris of the dome-shaped



  • If I’m reading this correctly, if the aperture follows the curvature of the glass you end up by saving some space which can lead to more compact lenses, if not for the M line, than perhaps we’ll see some smaller EF-S lenses.

    We heard rumour that some folk in the video world are selling off gear in anticipation of a global shutter capable of 2.5k video being made available on an, as of yet, unnamed DSLR. While the wording is hearsay, A global shutter DSLR would definitely be an advancement in film-making tech.


    Canon’s been pushing the threshold of video DSLR’s since the launch of the 5DMKII, so there’s no surprise that they would be working to incorporate even more “pro” level video tech in their cameras. It has been their push but, as this is from an unconfirmed source, be sure to sprinkle salt liberally with what you read.
