Lenses / Re: Buying Advice: What First Lens for a Full Frame?
« on: December 18, 2014, 02:29:34 PM »
Is the quality in optics noticeably better in the 50 1.4 compared to the 1.8?
If the two lenses are used in F1.8 aperture, both 50mm F1.4 and also 50mm F1.8, the F1.4 model will have sharper image, and has the fastest and silent focus.

If the two lenses are used in F2.8 then the F1.4 model has a litlle advantage in image quality.

If the two lenses are used in F5.6 the image will have the same quality in both lenses.

Dear friend Surapon.

I agree with the comments above, but I have a detail to add:

Avoid very fast chargers.
Chargers that complete charge in less than 2 hours, causing overheating and deteriorating the batteries.

Chargers completing the load between 2 and 4 hours are ideal for maintaining the health of your batteries.

The possibility of having a universal format with the new 14 bit per color is interesting. But the success of a JPEG substitute depends on its adoption by Lightroom, Photoshop, Windows and Mac OS.

However, for users to change their workflow, saving the processed images in a new format, it would be good that Canon and Nikon had this format option, in addition to JPEG and RAW traditional.

EOS Bodies / Re: High Megapixel Camera Coming in 2015 [CR3]

If it is a Canon sensor then my bet is that the IQ will be about the same as 7D2/70D and that the graphs and measurements from DxO will be about the same for all three.
The same DXO score the 7D Mark ii? :o

Impossible. :-X The reason the sensors EXMOR 36 megapixel get very high scores on DXO is the down convert to 8 megapixel, which dramatically increases the theoretical DR. ::)

A Canon sensor with the same technology 7D Mark II, but "stretched" up to 50 megapixel, would get much better score when DXO down convert to 8 megapixel, and the theoretical DR would overcome any camera that Canon has released to date.

landscape, portrait, concert/music
landscape
No clue... I'd probably lead towards a Rokinon 14mm, but I'm not a wide angle guy.

portrait
85mm f/1.8 usm... very solid portrait focal length, sharp wide open, only around $350 or so used... andit can use used for concert... but it might be a touch short depending on how far you are.

concert/music
alternatively, the 100mm f/2 is a solid option.  People don't talk much about it... but it does a solid job... and you get a touch more length.
Indeed, the uses to which the OP describes can only be properly served (on a budget) with prime lenses.

I strongly recommend Canon 100mm F2 for musical concerts and portraits. A lens forgotten by many, and almost as good as 135mm L.

Landscapes be well made with Samyang 14mm, but 40mm pancake could one supplement the set in the landscape where the exaggerated perspective is not desirable.

NOT a camera for my use. But I rejoice for those who need more megapixel. I'm glad more for shut up those who made mockery of Canon sensors in recent years, but will not buy anyway.

Third Party Manufacturers / Re: FYI: D750 light leak issues

What exactly is a light leak?
Light leakage is a problem in that light passing through slits or holes (not through the lens) and wrongly reaches the image sensor, or metering.

Canon quickly admitted that there was light leakage in 5D mark iii, and a few weeks later offered immediate and no-cost repair. ::)

Judging by Nikon history, they must deny the problem until in 2015 there will be a D760 without this problem. :-X

Canon General / Re: Sensor life
« on: December 14, 2014, 10:23:38 AM »
In normal use, should last for several years. But exposed to sunlight during live view generates overheating, which can denificar the sensor. The film also deteriorated with high temperatures, but you bought a new one after another 36 photos. ::)

Beware of lasers pointing directly at the camera lens, video mode. A powerful laser can burn a pixel row in a fraction of second.

I liked cat photo. But I made a poster of 1.2 meters of my cat and I saved a lot of money.
poor cat, don't you miss it now :-)
LOL :-)

Oh God! I DO NOT done this with my cat. :o
The word "poster" has another meaning in the English language? ???
The meaning I know of is "a large size print." ;)

I remember, about a hundred years ago, when my brother got married.  The Bride wanted to go directly from the church to a cemetary across town.  The bride, in her gown, was going to pray at the grave of her mother.  OK, a little weird, but if that's what is important to her, great.
The really oggly part was that she had a videographer and she had to do the whole getting out of the limo -- walking to the grave-- kneeling to pray-- and then returning to the limo about 4 times.
It just struck me as moving from a simple sincere praying at a grave into a big production with retakes.
There are two sides. 

1.  Retakes probably resulted in a much better final edited product. 
2.  Retakes seemed a bit.. well staged (duh) and getting far away from the original intent (praying to the dead mother about the wedding)

Is it common for "retakes" when it comes to wedding video? 
"I am ready for my close up, Mr. DeMille."
I do both photos and wedding videos (in different events), and never liked staged attitudes grooms.

For photos, okay pretend that the bouquet will play three times, and then actually do. But video, I advise the couple not to make staged actions, which always seem poor taste.

Business of Photography/Videography / Re: t3i, 60d, 7d.... which to sell
« on: December 11, 2014, 07:31:51 PM »
As the three cameras have the same image quality, the decision will depend on your use.

If you do not have to shoot 8 frames per second, or use tracking focus on fast objects, sale 7D and invest in glass.

If you think the T3i is very small and has few buttons, get rid of it knowing that is worth little money.

Sorry , but it is no longer the world's most expensive picture.
I just sold the following picture, "Angry Cat" to an undisclosed "Crazy Cat Lady" for $10,000,000......
According to the art world, the sale is a publicity stunt, and Lik has a habit of doing so.... Undisclosed buyer... completely unverifiable.... This is no different than having one's spouse write a check for $10,000,000 on your own bank account and giving it to you.....

Seriously: Yes, it seems just a publicity stunt to value the "artist". When he tries to sell works in the future, some collectors might think that is a bargain pay only $ 500,000.

Leica uses noble metals like gold, on the outside of some cameras, but does not use noble metals on your sensor? ???

Lenses / Re: Review: Canon EF-S 24mm f/2.8 STM Pancake
« on: December 10, 2014, 02:27:40 PM »
Why would anyone buy this EF-S 24mm STM, instead of the EF 24mm IS?

Size, weight and price. ::)
A perfect match for the Rebel SL1.
For larger cameras as 7D, it's worth paying more for EF 24mm IS which has Image Stabilizer and will serve in all EOS bodies.
