Roger has posted his test and the results are pretty interesting - be sure to read down to the 23mm test portion:

EOS Bodies / Magnifier MG-Eb/MG-Ef
« on: February 16, 2015, 03:28:25 PM »
As I trolled (think fishing, not flaming posts) the Internet, I found this press release and an overlooked item - Canon announced the Magnifier MG-Eb/MG-Ef for EOS bodies:

http://www.canon.com.hk/en/corporate/press_release/downloadFile.do?filePath=pressrelease/2015/10998/New_Product_pr_eng.pdf

I'm curious about this and the fact that they announced it with the 5Ds/R:

Lenses / TS-E 17 f/4L vs TS-E 24 f/3.5L II
« on: February 13, 2015, 09:36:21 AM »
I had to take my wife to the local University last night so I thought I'd take out the T/S lenses to take a couple of photos of Doak Campbell Stadium at Florida State and the Unconquered statue in front of it.  I ended up having very little time and didn't have a flashlight which made leveling the tripod tough.  I forgot to take off the UV filter on the 24mm so there's flare and worse flare (with the 1.4x III). 

 All shots are f/16, 100s, ISO 100, Shift +4 (I think, it was dark), no Tilt.  The idea was to frame the whole stadium each time and these are very lightly edited with minor cropping and no retouching.  I'll probably edit out the stars and flare at some point.  Also, note that this isn't vignetting - it's the glow of the stadium lights, which were turned on inside the stadium.

Hopefully this will give people a little better idea of the different looks of these lenses based on focal length.

TS-E 17 f/4L about 4ft/1.2m from the pedestal:


TS-E 24 f/3.5 II about 50ft/15m from the pedestal:


TS-E 24 f/3.5 II + 1.4x III extender about 120ft/37m from the pedestal:

Lenses / Rear Gelatin Filter Questions
« on: February 11, 2015, 11:46:55 AM »
With a 11-24 f/4 on pre-order, I was thinking about getting some gelatin film(s) for the rear holder.  If I remember, the holder on the existing lenses (14L, 8-15L, 17-40L, etc.) are all the same size.  Can anyone confirm?  If so, then it's probably pretty safe to assume Canon will stick with the same size.  Also, does anyone know the approximate dimensions of the gelatin that fits?  I thought Canon had a template in the manual or on a sheet of paper, but I can't seem to find that online - maybe it was from another manufacturer.

EOS Bodies - For Stills / CLDC: Introducing EOS 5DS & EOS 5DS R

Here's a nearly 15 minute video from Canon's CLDC on the 5Ds/R.  I'm off to watch it:

Lenses / CPN: David Noton on the new EF11-24mm lens
« on: February 06, 2015, 09:35:24 AM »
It looks like CPN has added the 11-24 to their site updates, including an article:

EOS Bodies / EOS M3 - Will it be Available Outside of Japan?
« on: February 05, 2015, 09:31:30 AM »
I know most are excited about the new 5Ds/R and 11-24 f/4, but I'm interested in the M3 as well, especially with the rumor that it will be sold in a kit with the EVF.

Are there any rumors/news about geographic availability?  Since this is a Japanese trade show, it could very well be that they are only announcing it for Japan.

Lenses / Who is going to buy the 11-24 f/4L?
« on: February 04, 2015, 03:16:11 PM »
Since we have one for the 5Ds bodies, why not one have one for the lens.

I'm planning to stay up tomorrow night just so I can be one of the first to preorder this badboy.  I can see myself making good money with one of my clients who always loved my Sigma 12-24 II work.

Anyone else plan to buy one?

EOS Bodies / Best Lenses for the Canon 5Ds
« on: February 03, 2015, 02:36:37 PM »
I remember this being a very hot topic in the Nikon world, so let's get things started.

Looking at DxOMark's Sharpness scores, it seems that the best lenses assuming optimal aperture and perfect technique are going to be assuming Sharpness of 18+ on the 5DIII and 12+ on the 70D (no data for 7DII yet).  I have also color coded the Top 10 on FF to see where they land on a crop sensor, which will probably be a better representation given the pixel density, which I'm guessing (I haven't done the math) will be diffraction limited around f/5.6:

EOS Bodies - For Stills / The Canon EOS-7D Mark II AF Grid Void
« on: January 27, 2015, 10:29:46 AM »
I have my eye on getting a 7DII at some point, so I wanted to know if any of you have run into the issue that Arthur Morris is talking about:

The Canon EOS-7D Mark II AF Grid Void

I just read this new article on the Canon's DLC Site and I'm itching to try it now, given how cool some of his shots turned out.  I haven't done this since my film days.  Has anyone else used this feature much?  If so, any shots and/or tips you want to share?

Canon General / New Gear Resolutions for 2015
« on: January 09, 2015, 01:03:38 PM »
Does anyone else have any New Year's Gear Resolutions for 2015?

I've decided to make up some - I wonder how many I will stick with:

1. I will only buy a new lens if it covers a focal length (or lengths) that I don't already have covered unless it is a upgraded or special lens (i.e. TS-E 45L II)
2. I won't pre-order every new Canon EOS / EF product that is announced (again)
3. I will stop buying new memory cards - I'm starting to exceed my hard drive space with CF & SD cards ;)
4. I will keep using my beat up old aluminum tripod until it dies (or RRS finally has a genuine sale)
5. I will only order a full Lee Filters kit if I can find all of the required components from no more than 3 retailers (wish me luck)
6. I will wait for new camera bodies to go refurb before buying them

What are yours?

Third Party Manufacturers / New Nikon 300mm f/4 - with DO-like optics?
« on: January 06, 2015, 12:34:18 PM »
Like most Canon guys, I read the Nikon press release with a bit of yawn, but then I saw this:

Smaller, Lighter, Faster Telephoto

Nikon has also introduced the AF-S NIKKOR 300mm f/4E PF ED VR, the world’s lightest 300mm full-frame fixed focal length AF lens2, which is nearly 30% shorter and 1.5 lbs. lighter than its predecessor. Extremely easy to handle and built to suit the needs of serious photographers in the field, the new 300mm f/4 lens utilizes Phase Fresnel optical technology to help correct chromatic aberration and reduce the overall size and weight of the lens, making it easy to pack for any assignment. Capable of producing tack-sharp images and beautiful background blur at a distance, Nikon’s newest FX-format lens also features four and a half stops of VR image stabilization3, a VR Sport mode, VR tripod detection as well as several of the latest NIKKOR optical technologies including electromagnetic aperture control, a Silent Wave Motor for quiet AF operation, ED glass for further controlling chromatic aberrations and Nano Crystal Coat for superior image quality.

It sure sounds like a DO or DO-like lens.

Update: Yes, it is - here's the description from Nikon's lens page:

Phase Fresnel
Phase Fresnel (PF) lens elements effectively compensate for chromatic aberration and ghosting when combined with ordinary glass lens elements. The PF lens element is based upon the Phase Fresnel lens, which appears to have a series of concentric circles engraved onto it. Utilizing a Phase Fresnel lens element allows Nikon engineers to use fewer lens elements, resulting in a more compact and lightweight lens. Due to the characteristics of a PF (Phase Fresnel) lens that utilizes the photo diffraction phenomenon, when there is a strong light source within the frame or when light enters the lens from outside of the frame, ring-shaped colored flare may occur according to shooting conditions. This phenomenon can be minimized with “PF Flare Control” to be included in Capture NX-D (ver.1.1.0 or later). For more information, see software Help/manual. Capture NX-D is available from the Nikon website. Be sure to keep your software up to date.

It's interesting to see that they are using software to tame the flare issues.

Technical Support / Repair or Return?
« on: December 16, 2014, 11:21:11 PM »
I got a pretty good deal on a refurb 8-15 fisheye during Canon's recent sale, but the stupid lens has some sort of washer/spacer right over one of the lens elements (see attached photo).  I can either return it for a refund (no exchange is possible as it's out of stock) or use the 1-year warranty and send it in for repair.  I'm sad as I have had about 6 great refurb experiences in a row

I'm really torn on what to do as I think it should have not have been this way when I received it, but then again, I can deal with the repair too as it was a refurb anyways.

What would you do?
