Reviews / Re: Review: EOS M System
« on: November 28, 2013, 11:10:13 AM »
I took my M on a recent trip to Kyoto as my second camera. I have to admit the images turned out alright, better than I expected. It works well in combo with my Mk II + 135L. Sometimes you just want something wide just incase, for a quick snap etc. couldn't be dealing with switching the 17-40L every time.

Here's a link to one with the 22mm. I'm at work and can't download and downsize etc.

Very nice shot.  Great colors and textures.  I too took the M on a recent trip to Israel and Italy as a back-up/light option to my bigger kit.  It is a great tool for that type of use, and I even carried it in a jacket pocket on one day in Rome when I didn't want to carry my larger setup.

Epic by Thousand Word Images by Dustin Abbott, on Flickr


Very nice, Dustin. Beautiful clouds and sunset. What is that bluish-green aquamarine ;) stuff in the foreground?


That was part of what caught my eye, too.  I think it was some kind of foam from the water.  It looks like bits of ice, but it wasn't yet that cold when I took the shot.

LOL!!! (Once again....What kind of hood do you have on that $3000 lens?). Funny post!

The attached is the "Dumb assed end"

I must admit I didn't research enough before I purchased, the Images from this Lens are 2nd to none among my ultra WA lenses, of which I own several, Canon 14f/2.8L II, Canon 8-15f/4, canon 17TSE, 14-24f/2.8 Nikon, Canon 15f/2.8.

With the exception of the 17TSE, all my WA lenses are purchased first for Underwater WA, secondary function, Landscape, but I sort of suck at Landscape.

I just couldn't imagine anyone handicapping a Lens by having a fixed Lens Hood like the Zeiss 15, in my view, "Dumb Assed".

And, after trying several Circular Polariser Filters it wasn't until I found the Heliopan Slim that I found a Polariser that didn't cause Vignetting, but that Heliopan cost $500 bucks.

So, amazingly sharp, beautiful contrast, smoothest Manual Focussing system I've experienced, but a dumb assed Lens Hood system.

Yes, as has been shown by others you can remove it, but after laying out 3k for a Lens anyone that brings a spanner or a screwdriver within 3 metres of this Lens while on my Camera, is a dead man, or women.

This post cracked me up.

I'm generally a Zeiss fan myself but the Nikon 14-24 (w/adapter) represents a much better value and is sharper across the frame when stopped down vs the Zeiss.

I have both,, the Zeiss is sharper and has better colour and contrast (although at certain apertures the Nikkor is better at the edges.. but not by much),it also has no problems with focus shift,the same can't be said about the nikkor..
+1. I have the Zeiss 15mm and did a fair amount of testing against a couple of UWA Canon lenses and found the Zeiss to be unmatched. The testing process for me was using stars, as they tend to show coma/CA/spherical aberrations very clearly. The benefits of the Zeiss for me were:
- Sharp at f2.8 as I don't have the luxury of stopping down for star pic's (a slight amount of coma in the extreme corners).
- A hard infinity stop. Much easier to use when fumbling around in the dark.

Coma, in terrestrial use, translates as image softness. But, as has been pointed out, stopping down will reduce that.

This is one significant advantage for the Zeiss.  The Rokinon/Samyang is incredible in the coma department (a lot of "star guys" use it for that reason), but the distance scale is lousy on the Rokinon, and the lens focuses WAY beyond infinity.  I essentially prefocus before I go out to do nightscapes.

Here is a comparison to the Rokinon/Samyang.

The Zeiss is a tad sharper at 2.8, but they are equal by f/4. Though this could be due to TDP having a bad copy.

The Zeiss also has a bit less distortion, but it's also 7% less wide so it's not apple to apples.

I definitely don't see $2,600 worth of improvement.


"The Zeiss is a tad sharper"....LOL..based on the corner resolution in The Digital Picture comparison tool,   I would think that you may be able to shoot sharper with a plastic lens rather than the SamYang...at ALL apertures... I don't think it is worth $359.  ...but hey whatever makes you happy...you are smiling!!!! Maybe around f/8 the SamYang is tolerable.  :P


I don't know what to make of Bryan's review and/or charts (he has never actually reviewed the lens), although I have been told that there are two variations/optical formulas (older and newer) of this lens, but my own review along with that of others say that the new version is in fact basically as sharp as the Canon 14L and is one of the sharpest wide angle optics available for a Canon lens. 

http://www.photozone.de/canon_eos_ff/532-samyang14f28eosff
Roger here at Lens Rentals says that he is a big fan of the lens and that it compares favorably with the 14L.

I've used about five different wide angle options, and the copy of the Rokinon that I have is so much sharper at all apertures than anything that I have used before that there is no comparison.  I have no doubt that the Zeiss is better still, but as it is about 10x the price...

P.S.  The Rokinon blows the Canon "L" wide angle zooms away in sharpness in every detail.


So Dustin...I believe you...do you think that The Digital Picture is using the same lens that you have or something different???? I  also, really respect Roger at Lens Rental...Did you pay $359 for your lens? ....and it is sharper than the Canon???? REALLY?


I have been told since doing my review that there was an earlier version of the lens that lacked the UMC element as a part of the optical formula and was significantly inferior to the newer version optically.  That being said, I went and checked Bryan's lens sharpness tool again and his does say UMC.  His chart shows a significant difference between the 14L and the Samyang, particularly in the corners.  But his results don't seem to match that of other very reliable reviewers, and doesn't agree with my own results, either.

I don't know how to account for his results.  I think Bryan is a great reviewer, but I don't feel like his chart results reflect my own experience.  His results show that the 17-40L is sharper at equal apertures, but I just dumped my own 17-40L because the results were so inferior to my Rokinon.

Look at these two links from ePhotozine:

http://www.ephotozine.com/article/samyang-14mm-f-2-8-ed-as-if-umc-lens-review-19621
http://www.ephotozine.com/article/canon-ef-14mm-f-2-8l-ii-usm-lens-review-23412

Of particular interest in their sharpness testing; it unquestionably shows the Samyang as sharper (than the 14LII), even in the corners.  Anyway, I can only chart it up to either sample variation or reviewing differences (which illustrates why it is important to read multiple reviews and then form your own conclusions).

« on: November 14, 2013, 08:50:03 AM »
Hey guys, I just got my 6D and I have a 85mm Jupiter 9 M42 lens. I was reading about the adapters with AF confirm, but also they said not all of them compatible with the 6D? Can you guys help me out and tell me where to buy, and which one?

I'm not aware of any adapters with focus confirm chip not working with the 6D so long as it is a Canon mount.  I've used multiple ones off Ebay (usually around $10) in both M42 and K-Mount and haven't had any issues.

« on: November 14, 2013, 08:47:46 AM »
For this shot I used an old Contax 50/1.9. It was quite hard to take because I had to focus before taking the shot and the camera was almost touching the water, so I couldn't see where I was focusing nor where was I framing. What do you guys think?

The full version is here http://500px.com/photo/52039064


Nicely done.  I find some of the vintage glass (Helios and Takumars are mostly what I use) have really beautiful color rendering.  Less clinical than modern lenses.  Focus looks pretty good for the scenario that were describing (which is, by the way, why I wish that Canon had included the articulating screen with the 6D).

I'm happy to confirm that I will have my hands on a pre-production copy sometime over the next month or so.  I'll let you know everything that I'm allowed to share during my review process.

Well, Dustin, anytime you're in the Brighton, Michigan, area, you're welcome to borrow it!

That's very kind :)

Here's a sunrise over Glen Lake, Glen Arbor, Michigan, shot with a 6D and a Zeiss Distagon 21mm lens.

Great colors.  I'd love to give the Zeiss a test drive :)
