I'm fine if Sigma copied the best 50mm lens ever made.
"Imitation is the sincerest form of flattery."

Not only is it flattery, but the modus for most innovations. Innovation through copying :) Most innovations we see today are incrimental. First we copy, and then we add a smart feature. Where would phones be today if it was´nt for iPhone? That was a real innovation, and Samsung and all other touch-devises have been piggybacking on that one innovation.

The Zeiss Otus is nearly 10 inches long, which seems to be what you need to avoid the double gauss design. The new Sigma is an inch longer than the last one, at 4 inches so I highly doubt that it will be any other design, but we don't know for sure.

The Otus is about 6" long, I don't know if I call that "nearly 10 inches".
Sigma seems to have an "enhanced" double gauss design, by the way:

I'm in no way a specialist and I might be wrong, but the 50mm Art design makes me more think it could be a retrofocus design like the Otus 55mm. Maybe someone with better knowledge could confirm or negate this.

I am shure that the new Sigma is a retrofocus design similar to the OTUS and just a little bit of an enhanced double gauss. I tried to list the lens sequency of different lenses/types: + means a convergent lens, - a divergent lens, lens sequences without blanks mean lens groups:

                  +- -+ Doppelgauß type
                + +- -+ + Planar type
            + + - -+ -+ +  EF1.2 50
        + - +-+ + +- -+ +- + Sigma 1.4 50 Art
        - - + + + +- -+ - + + Zeiss OTUS 1.4 55
         + - + - + - + - + +   EF 2.8 24 as another retrofocus design with positive first element


I marked the achromatic doublets red where I think the "Doppelgauß" genes might reside in the newer designs. From that I see that the new Sigma and the OTUS have similar genes and share negative elements in front of the core Doppelgauß which indicates a retrofocus construction.

Just my 2ct.

One is allowed to hope :)

Hey Alex,

It's great your getting the positive feedback for your images.
If I can make a suggestion - if there is an image in your folio of work that you like, trying getting large prints of them.
In my opinion printing photos out at the larger sizes changes how you look at and appreciate your own work. This is something I'm revisiting myself, as I've got too many images that have remained in the digital realm. Keep up the great work!
Second this.  You will see things in print that you might not see on screen as well.  I've had to reprint many times due to some details I missed the first time around.

+1 me too

I had a very nasty experience with this. On one of my first paid photojobs. I took what I thought was a clever group shot (the subjects stood on a bridge approx 100m away from me on a bridge, and me on another bridge with the 70-200L II + 2xIII TC. Well, the problem arised in postproduction. I was fairly new to Photoshop, and unbeknown to me at the time,- quite heavy-handed with the sharpening. It looked great to me on the screen. I did not know that they would expose the picture on a 3m wide and 1.5m height steel plate... The two people in the middle got somewhat of a halo around their heads. Luckily for me, only people who knows pictures and pp sees this, but a great learned lesson for me. Now I always zoom heavily in on the picture whenever making corrections.

The second reason why I agree that you should start printing, is that the choice of paper/material greatly influences the kind of expression that you want for the image. I have a Canon Pixma Pro 1, and it gives me the opportunity to experiment with different paper types (also from different brands). The difference of your moose shot on a matte type from Canson vs. a high gloss one would be considerable. Given the hardness of your light and highlight I would probably opt for a high gloss rendition, as detail are accentuated on this type of paper.

just my 2 cent :)

I think the moose shot is excellent! Love the light in the horn?.. and the lightplay in the water. The first shot looks a bit too HDRish to me, but that might be my screen. You obviously have a great talent for this, and I suspect that you already have familiarized yourself with Lee filters, although I do not see them in the gear list.

Keep up the good work!

While such a move might be good for the overall income of Canon, through tax breaks and the like, I assume that the labor cost of workers in Japan is quite higher than in the countries where they have had outsoured production. Hence, it might be a negative shift in prices from a consumer point of view.

Also, it still does not alter the fact that the chains selling the Canon products, buy in Yen, while they have to sell to the consumers in those countries in their own currency. Large retail chains in Europe are bleeding on Canon products because of the yen, which they again have to push on their consumers. In Norway the 135L could be bought for about 1000USD, while now it has jumped to approx 1300USD after the negative shift in the Yen.

Imho, this whole thread has become like the humorous article posted in Photography Life where there was a fictive discussion between the heart and the mind in regards to the Nikon Df camera. I have a hard time understanding why this should be such a heated discussion where people are getting agitated, and almost resort to namecalling.

Is this not a really simple matter? Nikon is releasing a new camera to the joy, indifference, or agony of their existing base or potential users. Their success depends on if these people find it to be a worthy upgrade, and not other brand users who seem to be involving in heavy post-purchase rationalization.

277
What I do love about this anouncement is the audacity! Sigma is shameless. They should be content with their inferior position in the market place, but no, - for the couple of last years they have gone hunting :) It reminds me of a classic ad for a US car rental company in the eighties... "We know we are number two, therefore we try harder"

VERY interesting. Something has to happen in the Canon camp!

How so for you?:) You have pretty much all of the goodies Canon has to offer and then some. If you want to develop further, I would expect you to turn your attention towards Hasselblad? and not bother what Nikon does... imho :)

I think that your question probably is part how you take the picture and partly how you PP it afterwards. I have spent a great deal of time reading on a astrophotography thread today. I would post your question and your beautiful picture in this thread, as Jrista and Don Haines and others there would probably be able to answer it in detail :)

This is imho the most inspirational thread I have read in this forum for quite a while!

I have never tried astrophoto myself (except when I was lucky to borrow the 800/5.6 with a 2xIII TC to take picture of the moon, but that would hardly count as the moon is very bright so the exposure time is very short).

I have been reading this whole thread on my ipad retina, and it has quite good resolution. However, due to the restrictions on image size here in CR, I would have loved to see full resolution images of your beautiful pictures if you guys have posted them somewhere else? :)

I always enjoy reading his articles, and this one had quite a bit of humor in it as well :)

This coming from a guy who works with marketing, and is the first to fall for marketing catch words :)

Canon General / Re: Review - Canon EF 85mm f/1.8
« on: December 30, 2013, 11:02:44 AM »
Wish my 85L II has same AF speed as f1.8

I was a little surprised that AF speed difference was not mentioned. Being able to focus quickly in low light was a major point to chew on when I was looking at the 85mm 1.8, and it has a lot to do with why I am keeping it. Well, that, and the focal length plays well with what I do, it doubles as a portrait lens on FF, and the results are very useable wide open.

I agree totally, the AF speed is non-surpassed of the 85 for Canon I have tried. It is actually super fast. Mine, the Sigma 1.4 is not that quick, and I quite like it. However, after having borrowed the 1.2 for quite a while, I have to say that I regret using it, as it made my Siggy 1.4 less of a lens afterwards....

Interestingly, the comments about the chromatic abborations are true, but what he fails to mention is that (although not as prominent as the 1.8) the 1.2 also has its fair share of CA.

Photography Technique / Re: Perspective correction
« on: December 29, 2013, 03:20:57 AM »
I'd only recommend DxO if you shoot a lot of UWA shots that you don't wat to look like UWA shots, otherwise everybody else is pretty much as good for regular perspective and distortion corrections.

With emphasis on the results and with practice that might be true, but at least as LR/ACR is concerned (I don't know about PS) DxO has a very nice and quick visual user interface which makes the correction a breeze.

In LR you can either have Adobe's upright have a go and if this fails have to tune the sliders for ages until you get what you want... at least I'm still struggling to do proper corrections that aren't minor, somehow it always ends up looking a tad wrong unlike with DxO. Having said that, spending the €€€ on DxO might not be necessary if already owning LR, gift horse and so on.

I much prefer PS, over the Lightroom and ACR adjustments particularly now they have the three auto options, they are trying to be too clever, and, as you say, if you go into manual they can take forever to fiddle this way and that. The actual lens corrections, the profiled auto settings for lens induced distortions, CA, and vignetting are very very good in LR/ACR.

As for perspective "corrections"/adjustments, I find PS to be very simple, but you do need to understand what you want the image to look like and which direction to move it in to get it there, a couple of keyboard shortcuts don't hurt either. Rather than try to explain the way I do it, I thought a video would better illustrate the method, so I made one, here, forgive the questionable production quality, I only ever did one of these before.

I am very impressed that you went and made a video to share on how to perform this operation in PS! This is such an act that makes this a great community. As for the actual distortion correction, I used to make them in Photoshop Elements and I loved that function. However, once my job installed the full PS version, I was not able to keep it, hence I learned to do the transform in PS.

PS. I would not mind if you had some time one day to make a video (in the other thread on group portraits (where you commented on my picture)) on an easy way to whithen out parts of the backdrop that was not strongly enough lit, hence you still see the structure of the backdrop. Up until now I have used the Clone Stamp tool, but it is tedious and easy to miss out on. Also another turorial if you have any good tip...? I have seen the professional graphic designers at work remake a white background to whatever color they want, without altering the subject/person in front..
