On Tamron SP 150-600mm F/5-6.3 Di VC USD Lab Test Review preview (218 comments in total)

Dpreview, There should be a measure at 500mm. After 400mm jumping 200 mm to 600 does not cut it.

My opinion is, for the price this lens is very good. But 600mm is mere feel good, since at 600mm it just provides 10%-15% more resolution than a 400mm prime. (even comparing with this lens itself, it will bring about 20-25% more detail only zooming from 400 -> 600)

The canon 200-400mm resolves 15% more throughout the range, but too pricey.

nicolaiecostel: 6.3 ? Seriously ?

6.3 makes sense since it provides compactness for the lens too. 6.3 is not slow when iso1600 compensates and yeilds quality output. The loss of bokeh in 6.3 cannot be avoided, but a person who worries about bokeh in the tele-end probably won't buy a mirrorless compact anyway.

jaykumarr: My observations in this pic:
1) Sony is a bit sharper at center & top left. Everywhere else Panasonic is sharper.
2) There is chromatic aberration in panasonic's output.
3) The panasonic has better lens, while sony has better sensor.
4) Sony applies a little more denoising in default mode than panasonic.

I wish dpreview do comparison in long end too.

regards,
jay

0lf, Fropetessake,
True, the entire left side Sony wins. I don't understand what kind of conclusion we can come too, if there are differences like this.

But one thing clear: Panasonic/Leica can no longer boast the 'detail supremacy'. Others are getting very close.

Still panasonic is solidly sharper in RHS edges, while Sony is moderately sharper in LHS.

mauijohn: The japanese plan after they occupied the Philippines is to mine all the natural resources of the entire island of the Philipines such as copper, gold, timber, iron etc. They will use the people of the Philippines to work manually young and old and they just killed those too weak to work. Japan has a very low on those natural resources on their land. I will called this big time terrorism that will look Boko Haram and alquida combined like a chiken.

1) One person claiming that he got a Ph.D is pointless, since no one can verify it. Even can claim to have won Nobel prize, Turing award, Japan prize all twice.
2) When a Nobel laureate was called as 'negro', what one's Ph.D can do?
3) How foolish is a person to brag that he got a Ph.D, when no one questioned his education / brain functionality? I told I have a masters degree since someone told I am a moron and have brain.

Ok.. whites are supreme race... They are kindest, but unfortunately had to drop few bombs. you know, whites will do anything to save this world..

could you please explain, Why America sent the biggest war ship then 'USS Enterprise' to nuke India in December 11, 1971 supporting Islamic Republic of Pakistan? Was India Terrorizing US by attacking pearl harbor?
Another example of American pride :

stdavid: Munro the Americans were at war. Terrorism is a much different matter. It was a terrible decision to drop those bombs. I totaly agree. But lets not forget the Japanese were masters of terrorism.
Just google the"The Rape of Nankin" that took place in 1937 in which the Japanese slaughtered 300,000 of the 600,000 residents of that city in six weeks. And..there was NO war.

In reply to:

hrt: The only way we can possibly learn to stop wars is to know about the disasters, cruelty and sorrows of war - and photography is indeed a powerful media for spreading that knowledge around the world. From this standpoint, I don't really get the idea of auctioning Nagasaki photos for an individual's ownership.
All such photos should be shared publicly to remind us possible insanities of our species.

I wanted to type 'Do you know', but it was a typo. Even if I do not know English, I am not inferior as you think. Knowing English is another language. Only a racist will think English knowledge is great and those don't have it are inferior race.

Indians have castes openly for 2000 years. But Indians did not kill lower caste people. Whites claim 'non racists'. But they killed millions of people. Until 1970s Whites had law in Australia to steal children from Aborigines since Aborigines cannot bring up kids like 'white men' and practiced it even after 1970. (probably whites wanted to bring up kids as blood thirsty racists, which natives don't do)

Your Ph.D is ass wipe, because you call a even a Nobel prize winner as 'negro'.

Well, your points are not germane. Answer these:
1) Why America sent warship to nuke India in 1972? Did India do Pearl Harbor?
2) India has elaborate system to help lowercastes. 50% jobs are reserved for lower caste people. What do you have for blacks in US?

Do you Dulles? Do you remember airport named after him?
He did war on helpless countries for money and killed thousands of people. America did not just help him but made him a hero.
Do you know India? it is a country in Asia. Biggest democracy in the universe. Before US gave even voting rights to Blacks, Indian parliament had women, had representatives, ministers of lowest society. US sent the biggest warship in history to nuke India, Because US loved Islamist Pakistan and supported Muslim fundamentalists killing kind Hindus.
I am not against US, actually I love US, but hate astraying information like what you give.

Else, not a great tool for the price.

In reply to:

jaykumarr: Amazon is a seller. Amazon owns DPreview.com.

That explain why every possible consumable item that has Camera appears in DPreview.com.

Soon, DPreview.com will review or preview Hard disks (that can store photos), printers (that can print photos) as long as they are sell/list -able in Amazon.com

I said what i said in a 'general' idea not specific to this article. I feel that dpreview is publishing too much news and I am addicted to their news.
