pshummer: AF speed of my Sigma 150-600 C has substantially improved after I installed the new firmware update by a Sigma dock. Nikon/Canon should follow the Sigma's idea. The Sigma dock is such a huge time saver.

Was yours slow previously?

Engineering Manager: "we fixed the problem that was slowing down the focus by 50%"
Marketing Manager: "Our fix made focus faster by 50%" . So buy dock from us.

jaykumarr: A very good detailed review indeed.

I have a doubt. Tamron 150-600 resolves 1700 lines at 600mm F8.0 while this resolves 2100 lines at 400 mm F8.0. That means, still Tamron would resolve about 15% better. Is that a better choice for tele end? (of course, the output quality will be still better in this one due to low CA, accurate focus). http://www.dpreview.com/reviews/lens-compare-fullscreen?compare=true&lensId=canon_100-400_4p5-5p6_ii&cameraId=canon_eos5dmkiii&version=0&fl=400&av=8&view=mtf-ca&lensId2=tamron_150-600_5-6p3_vc&cameraId2=canon_eos5dmkiii&version2=0&fl2=400&av2=8

I thought my camera had problem, so i gave to my friend, and the return period passed. However, I sold it back to KEH camera for 200$ less. (I did not want to sell to someone else and cheat)

heheh... so you are saying 3 KG Sigma is better than 2 KG Tamron? Though isolated incident, I bought a Sigma 100-300 mm F4 (used) from KEH which had poor resolution and consistently missed focus. May be my digital rebel camera is too old, I am not sure what to blame, but I know sigma is not worth it weight.

// After 15 long years, Canon finally upgraded one of the biggest-selling telezooms of all time - the 100-400mm F4.5-5.6L IS USM.//
And dpreview is reviewing well past 1 year in the market?

jaykumarr: silver award.

Reason: Noise and HDR lacking behind competition.

@Az..
do you want me to wait and predict after the sensor is tested and dpriview published the review?

In reply to:

Nukunukoo: The biggest problem with organic sensors is that the bigger the sensor the more heat it generates which significantly reduces its usable lifetime. This is the reason the first applications will be on small mobile devices. The OPF layer is very intolerant to higher temps. Still, the science has game changing potentials and I am excited when it comes to more mainstream use years from now.

That s what panasonic wants.. so you buy a new camera every two years

Hopefully we will see Panasonic implement this in their new photo and video cameras in the future.

I was praying Sun god too

I was not able to understand 50% it first. After looking at diagrams, I understood them all !! thanks for graphic dpreview. Hope USDA will certify it Organic too.

So, should I wait for FZ-1000 successor with this sensor? how long will it take for this invention to reach sales?

Does this have anything to do with justifying ridiculous price of stepping lens they are going to release?

Link | Posted on Jan 29, 2016 at 17:40 UTC as 34th comment

Why is that Nikon has more than 4 product lines for APS-C/DX SLR alone? 3000 series, 5000 series, D90 etc, D300/500 . I think it is too much trade off in several ways. It is not even clear what lack what. like if 3000 series has 3D focusing or not, why is pictures/videos of 5500 sharper with same lens etc.

are these black birds lifting an orange together and flying? or they are thinking you are taking photo of the sun so they ensure they don't block you?
