Canon General / Re: Spartans, What is your profession?
« on: March 01, 2015, 12:50:50 PM »
Worked as a physicist, systems engineer, and IT and Info Security exec. I lived below my means when working, saved money and retired early with no debts, no mortgage, no car payments. I live well in retirement with my husband who has no GAS of any kind - just give him books and he's happy. We travel several times a year and I satisfy my GAS by saving or forgoing a trip. I go out with my camera several times a week at home to take bird photos but I never sell anything.
Sounds like you got your priorities right and have a good life :) I have the money I need to buy whatever my GAS tells me to, but not enough time to enjoy it, as much as I should. I think I have a thing or two to learn from you ;)

I always wondered which was the first cat image  ;D

I spent quite a bit of time in Silicon Valley in the mid to late eighties (I was an ASIC designer in those days) and remember this era well. Very exiting times.

Who were you designing ASICs for?
I was working for a Norwegian company called Elektrisk Bureau, which a bit later was split and taken over by Ericsson and ABB. In Silicon Valley I primarily worked with ZyMOS and LSI Logic, but we also made some analogue circuits with Hughes in Los Angeles.

Communications research....

First major project that I worked on was Telidon.

The project predated the internet and influenced many aspects of it's design, including the concepts of HTML and the idea that you could connect from anywhere. In 1986, when the internet was officially created, we were part of it.... and here is a picture from 1986.... the first cat picture posted on the internet!

I am running a company delivering communications, navigation, surveillance and automation systems to airports and air navigation service providers across the world. Currently we have systems operating in more than 120 countries, so I get to travel quite a bit and enjoy meeting all the cultures of the world. Except for the US, which is a very protected market, we have about 50% of the global instrument landing system market, so there´s a good chance that when you´re out flying, our systems are bringing you safely to ground and up to gate.

Photography has been one of my main hobbies since the mid seventies (the others are music/hifi, food & wine and flyfishing) and it is occupying more and more of my (limited) spare time. I have absolutely no commercial interest in photography. It is just for fun and that is probably why I enjoy it as much as I do. Maybe I´ll pursue a second career when I retire from my current job  :)

What are people's thoughts on the Otus' switch to a rubber coated focus ring? How does it feel compared to the metal on older lenses?
I think both are good and I live happily with both. But the Otus focusing mechanism is smoother than the others, so that adds to it. If I had to choose I´d pick the Otus, but it might be because of the very smooth and also very precise movement just as much as the rubber coating. i also like the shape of the Otus lenses. They are simply good to hold.

Lenses / Re: Gear for upcoming trip to Italy and Greece

For those who worry about theft. I have travelled extensively over the last 35 years (close to 100 countries). I always bring more camera equipment than I need, which is usually more than anyone else would have carried. I shoot any time of day, any day of the week everywhere I go. I keep my head on my shoulders and use common sense like avoiding dark allies when I am alone etc., but apart from a stolen bag in 1984 here in Oslo (I fell asleep on a train), I have never lost a single piece of equipment to thiefs.

I have spent a lot of time in both Greece and Italy, but never off a cruise ship, so it might be that my experience is a bit off what you´ll meet. I also carry more equipment than most think is fun, so I´m probably not the carry-light-advisor you´re looking for ... But for what it´s worth:

From the lenses you list, I would bring 16-35 f4L IS, 35 1.4 and the 135/2.0. If you´re willing to carry more, you can add the 70-200 and/or the 85. But my experience is that I always use the 70-200 (mine is the 70-200 f2.8L IS II) less than I thought I would. But I use the 135/2.0 a lot (used to be the 135/2.0L, but I now use the Zeiss 135/2.0). I always carry the 24-70 f2.8L II, so that would have given you a fair focal range coverage, but in your case I would be worried about the big gap from 35 to 135, so that points towards bringing either the 85 or 70-200 also.

In any daylight shooting you´ll have more light than you need (want) and can use any of your lenses (I´d bring circular polarising and ND filters!). But my favourite time of day to shoot, especially when you´re out on the Greek islands, is just before and after sunrise and sunset, when the special Mediterranean light is at its best. So to shoot anything with people in it, you´ll be glad to have the fast primes. And, even though you have not asked for it, I´d recommend a tripod, even if it was just a Gorilla variant.

Bags are difficult. I have lots of them, because I always struggle to find the right one for That special trip. But for your use, I have recently used the Lowepro Classified Sling 220 AW, which I am growing more and more fond of. It is comfortable on the shoulder, big enough for a 1DX or 5DIII, 16-35, 35/1.4, 135/2.0 and the 70-200/2.8L. It is also big enough for filters, a flash, charger and a 15" MacBook Pro. The big advantage with the sling bags is that they are out of the way when you don´t need them and gives you very handy access to all your gear when you want it, by just pulling it around from the back. This bag is probably my best value for money alternative ($54.95 at B&H).

Enjoy your trip and share some pictures when you return!

Lenses / Re: Which Lens to buy for Portraits

How about a comparison between 85 L I and 85 L II.  opinions?  I have the opportunity to purchase at 85 L I at a good price.  How much better is the II?
This is from memory, since it is quite a while since I had the version I and I have not used them on the same body, so I do not have any objective material to look at. I don´t have any of them now, because I sold it when I got the 85mm Otus.

(From memory) I don´t believe the 85 1.2L II is optically better than version I. I´m sure there are people out there who have done side by side comparisons and may be able to tell the differences, but I cannot. They both suffer from CA, but apart from that, I loved the IQ both lenses produced. Bokeh is beautiful on both. AF is a bit slow on vII, but even slower on vI. DOF @f1.2 can be quite challenging, but rewarding when you nail it. For the kind of use I had, AF speed was not a real issue. AF is a bit faster on a 1D body than any of the others.

A version I for a good price is well worth it, in my view.

EOS Bodies / Re: POLL: Are Zeiss lens users more likely to get a 5dS/R?
« on: February 19, 2015, 04:29:07 PM »
It will be interesting to hear from users as to how good of a manual focus they can achieve thru the viewfinder.  I'd suspect that getting better manual focus to match the resolution of the sensor is going to take some pretty careful work.  Just the vibration from having your hand on the focus ring might make it difficult to get the very finest focus. 

I used 5 different Zeiss / Hasselblad lenses adapted to my 5D MK II, and got a low percentage of sharply focused images using a sturdy tripod and live view.  I struggle with my vision, so I am probably a poor example. 

When I mounted the combination to a strong tripod head that was literally bolted to a heavy and sturdy light table, and viewed the image at 5X tethered to my 24 inch monitor, I could manually focus to near perfection.  I loved the smooth long throw focus, and wished I could do better.  I even bought a split prism focus screen for my 1D MK III, and tried that, but it was not accurate enough to get the sharpest focus.

Most Zeiss users already know this, so they certainly will not get results that are poorer than what they get now, and will almost certainly notice the improvement, its just a question of how close they can get to perfect focus on a regular basis.
I use my Zeiss lenses a lot and both the Otus lenses (55/1.4 and 85/1.4) and the 135/2.0 are very often (most of the time) used wide open. I only focus through the viewfinder, with an Ec-S screen in the 1DX and a custom made S-screen in the 5DIII. It takes a bit of practice, but I have very high keeper rates (well, at least from a focusing perspective), even in rather poor light. I´m not sure how much worse it would be to shoot with a 50MP camera, but I suppose we will find out in due time. For the moment I am still on the fence regarding the 5Ds/5DsR. 

This is shot handheld, focused through the viewfinder at f1.4. I used 2 soft boxes, so the light I had to focus in was fairly dim. But with the S screens (this is with the custom made screen from Focusing Screens for the 5DIII) it is pretty easy to see when the eye is in focus or not.

Lenses / Re: 16-35F4 L IS, Any good?

I have had a couple of 17-40 copies and I have had several of both the 16-35 f2.8L vI and vII. I never liked any of them. But the 16-35 f4L IS I have is simply brilliant. I actually sold my Zeiss 21mm f2.8, because the 16-35 f4L IS made it redundant. I have not heard anything but praise for this lens, so if you're not happy with the two copies you have seen, it must be something wrong somewhere in the chain.

Leaked from Zeiss says 24/1.4 (but you never know until you know :))

There are lots of birds in Cyprus. But the majority of them are wearing bikinis and I suppose that´s not the kind you were thinking of  ::)

Chinese Goose... For some reason it looks like crap unless you click on it.
I had the same issue. I changed to sRGB and then it worked.

I inquired with Canon via e-mail on the focusing screen issue, and they could not tell either way. The 5dmkIII focussing screen is also indicated as "fixed", but can be changed by removing a couple of screws, so I suspect it will be the same for the 5dS. Re getting focus right, I don't think I have a lot of problems with that. Between focus confirm with specific AF point highlighting, and live view with magnifier function, I'm pretty happy. I currently have a Haoda screen in my 5dmkii, but may go for the Ee-S to avoid metering problems. I guess you are aware of the 0.15 mm difference in thickness of the focusing screens for the 5d and the 1d. On my microscopes I also use over-under-middle focus, and that works very well. Same on LF with loupe on ground glass. Focus creep with stopped down lens should be minimal.

Re vibrations, except for macro work >1:1, I see no problems. The vibrations themselves do not change the focus, and long lenses are collar mounted. Vibration during exposure is critical re sharpness, of course. I usually use live view and remote shutter release. In the field my backpack hangs from the platform and is resting on the ground.

I guess someone has to be the guinea pig, and I'll gladly be it. I also preordered the Otus 55 back then in anticipation of the 5dS, and many were skeptical. I haven't heard too many complaints since (except for price).
Yes, changing the focusing screen on the 5DIII is less difficult than most people think. But you can´t do it in the field and you have some hassle with the EC. But, since I also use f4 lenses, I want to be able to swap screens in the field, because the S-screen is too dark.

I have tried the Ec-S screen in the 5DIII and that does not work well. It does not fit mechanically and I got some strange optical phenomena, which made it totally useless. The Focusing Screen version works OK though.
