carl zeiss is the only lens company that can make a wide angle lens

Canon L wide angles are pathetic
In reply to JackM • Sep 15, 2008
Let's face it, Canon cant design a wide angle lens while Zeiss rules.. Zeiss needs to get that 21mm converted to Canon asap.
I agree, does the market need an $800 50mm? Or a $1400 85mm?

german camera leica is the best camera in the world

Re: Is Zeiss better than Canon L?
Zeiss and Leica are in such a league of their own that any discriminating viewer of photographic art will know not only what camera and lens you took to make the photo, but that you are a very awesome photographer.
Yes. That's just the ticket. Isn't it? Er, maybe not.
The Zeiss lenses people are drooling over are made in Japan by Cosina, not in Germany by Zeiss.
Optical glass comes predominantly from China these days. Everyone uses it, even three letter agencies in the USofA. Optical glass from other countries is simply more expensive and are dying industries. China roars on, however, and this is where manufacturers have to go to get their materials.
The Zeiss designs you see for Canon, Nikon, and M42 Pentax all come from the time when Contax offered 35mm SLRs. They were/are good designs. But I have seen variability in implementation. From any manufacturer.
Its this variability in manufacturing that seems to get some of you guys all lathered up over which toy is better than another. Modern DSLR lenses are hideously complex. A few lenses make it to the street that should not have passed QA.
The manual focus Zeiss lenses are less complex. Yes, optics still need to be properly ground, centered, and assembled. Yes, Zeiss can specify the level of QA they want before Cosina can slap the word "Zeiss" on something. I'm sure its all in the contract.
From one perspective, its a matter of money. Have the money? Spend it. However, I doubt new Zeiss user's "art" will be any better than it already is today, pre-Zeiss and all that.

federer beat nadal in austrailian open 2017 with injury and hurt leg

Federer said: "I explained myself a couple of days ago after the Stan [Wawrinka semi-final] match. My leg has been hurting me since the [Noah] Rubin match [in the second round].

"I was happy that I was able to navigate through the pain. For some reason against Stan I had it from the start on both sides of the groin.

"After he took a medical timeout, I thought I could also take one for a change and see if actually something like a massage during the match is actually going to help me. It did a little bit potentially. I'm not sure.

"And then today after probably - well, I felt my quad midway through the second set already, and the groin started to hurt midway through the third set.

I get 51MPG on my diesel BMW. Car is 13 (2001) years old. It is faster. It has more room. It is cheaper.

+Arnis Tarassu To be honest i think you MPG numbers are incorrect, since BMW best MPG 2015 model 2015 BMW 328d  gets only 37 MPG combined. Also, it would be great if diesel vapors  were not highly carcinogenic.
Harmful emissions are far greater on diesel than on gasoline cars.
So to make things short, you are comparing apples and oranges...

+vladabas I'm not sure about MPG conversation  but I can drive exactly 1250km (sometimes 1210, sometimes 1280) on 69 litres of fuel. I use GPS for distance measurement and receipt for paying for fuel is amount measurement. Using  google converter I get 51mpg. Also it is European vehicle, 4-cylinder diesel.
My vehicle does not make "diesel vapors". CO2, N2, H2O mainly. Also I don't start the engine cold in winter as vehicle is equipped with fuel preheater.

This MPG rating is exactly why Prius is not common in Europe.

How is it possible to have a diesel car that is not producing diesel exhaust?!?!?!
International Agency for Research on Cancer (IARC) – part of the World Health Organisation – announced that it had reclassified diesel exhaust as a ‘definite carcinogen’ – putting it in its highest category (Category 1).
My Prius is currently at 48 MPG, so for that small amount of difference in fuel consumption i will gladly trade for a non carcinogenic petrol car.

+vladabas There is no such thing as common " diesel exhaust". There are different chemicals that exit the tailpipe. And concentration of those depends on the vehicle. Don't believe everything. Euronorms show not a lot of difference between gasoline and diesel engines. Most notable difference is NOx limits. Still, this is not called "diesel exhaust" nor "diesel vapours". Gasoline vehicle exhaust is not air from Mount Everest also.
Anyway the main topic is that my old BMW uses about the same amount of fuel as hybrid drive.

Well according to official data your car can somewhat match Prius MPG only on highway.
In the city it should be around 35 MPG.
Is your fuel consumption mostly on highways?

+vladabas I researched those mpg test procedures. City really means heavy traffic and a lot of stopgo situations. I have excellent right foot in city. I hardly ever use brake pedal. coast a lot. Also where I live our cities are rarely jammed. At night when traffic is very low and speed is around 25-35mph constantly efficiency is astronomical, 70 or more.unfortunately it is not sudtainable as there is always a reason to slow down. still for short trips I use Leaf and for hyperlong trips I use diesel. 50-60mpg is highway average on longer trips.

Man you are starting to sound like a PR of BMW.
Your cars consumption as specified by BMW is 30 MPG in city and can only be compared to Prius in highway drive
Fuel Consumption - Economy - Combined:  5.9 L/100km
48 mpg UK / 40 mpg US
Fuel Consumption - Economy - City:  7.8 L/100km
36 mpg UK / 30 mpg US
read more at: http://www.ultimatespecs.com/car-specs/BMW/5072/BMW-E39-5-Series-520d.html
Those are specs by BMW, and now you are telling me that you are getting more than double MPG... Yeah, right!

Also "Euronorms show not a lot of difference between gasoline". Are you serious? All tests show huge difference between diesel and petrol engines. Remember VW scandal with diesel engines?  The programming caused the vehicles' nitrogen oxide (NOx) output to meet US standards during regulatory testing, but emit up to 40 times more NOx in real-world driving. 40 TIMES MORE during regular driving!
Obviously you know better than World Health Organisation that put diesel exhaust as a definite carcinogen. http://www.bbc.com/news/health-18415532
Seriously there is nothing else to discuss with you since your data does is far off from real world results.

+vladabas Haha. Whatever. Fuel consumption is not a constant. And there is no such thing like "city" and "highway". Those are tests that are average. WHO might put it to cancirogenic or whatever list but people in EU have less cancer than in US, where Diesel vehicles are very very rare. Explain that. Also there is no such thing like diesel exhaust. There are chemicals that are exiting the exhaust. And VW scandal is a scandal. If you don't understand the problem in that then stop saying "40 times more NOx". There is much more NOx exiting your chimney than 100 diesel VW's.

peugeot is the most reliable car in the world

Peugeot used all over europe as taxis
