F Stops vs T Stops – what is the difference?

Ray: “Your readers may be interested in a saga I’ve had with Olympus Australia and artifacts burned into my E-M1 EVF. It’s not a major issue at the moment for me, but Olympus Australia can’t seem to answer some simple questions regarding these artifacts, which is of importance to everyone. The full story is here: http://australianimage.com.au/wordpress/?p=2517.”
Leopold: “Here are 100 image samples of the new SLR Magic 10mm/2.1 MFT lense. My explanations and conclusions are written in the album description.

Very informative, thank you so much!
Very crap more like but the admin here are in bed with grainger…….
He does intimate portrait work…more like on the bed.
The clown in the video needs to look up the proper definition of F stop. It’s neither the diameter f the diaphragm nor the diameter of the front lement, both faulty claims he makes, but the ratio of the focal length and diameter of the entrance pupil. The entrance pupil’s location is not a physical but a virtual location witin the optical system, and certainly not synonymous with the location of the diaphragm or the front element. Thumbs down.
He had made interesting claims previously, like the “zoom with your feet” is nonsense, without understanding what it does mean.
I have servants that help me zoom with my feet. I simply click my heels and they move my carriage so that I may take the shot.
Grainger is a ‘name’ therefore he must know all things…….
yawn
@admin
Part 3 is out! It’s more interesting than part 2.

The Nocticron test by PekkaPotka is a bit short & incompleted .
Looking forward to read full PekkaPotka review on this lens .
i think enough tests in a similar way are already done. Maybe some labstyle analyse for the nrs could be done too(havent checked for that). Maybe the net lacks enough sites who focus on the rendering of the lens wideopen, maybe because except for its ability to blur away the background if the subjest is not too far from the lens, but due to its clinical character like so many modern designs these days, its maybe less interesting then a specific older legacy portrait lens, which can make look a shot very special. Pekka Potka’s shot of the 2 girls together shows the awesome sharpness vs blurred background rather well. I just find it a pity that his subject’s distances are not ideal for checking how much this lens can show blur /object isolation. My reference for this is the canon EF 85 f/1.2, which can handle full body isolation in this classic FL. Ofcourse its much harder to do in MFT in 42.5 or similar. halfbody or close portraits are much easier to show a prime lens ability in this.
Now you aware why I insist the Nocticron should not in 42.5mm in my earlier comments , it should in 45mm at least or 55mm to give way to more bokehlicious effect that close to FF .
m4/3 need to establish it’s own FL rather than just follow with other format’s FL .
Btw , how is the war last night ( FF vs FT ) ? Hit 132 comments , still on going with no victor yet .
Yun, my opinion is that it does not matter if you work with either 42,5 or 45, except if you do indoor session in a smallroom like mine, where every mm extra helps to get a full body shot. I think the 75 or more helps more for the looks you mentioned, but its less flexible for many shoot scenarios. I did not follow that war last night 🙂
Frankly, I never trust reviews, and the m43 reviewers are worse than average. I always suggest that people go out and test stuff themselves.
You are definitely wrong on this one .
Need to change your mindset for sure .
All the reviewers got it’s own merits although they might not fullfill what you
expect from them .
Are you saying you trust strangers more than yourself? It’s minds like yours who keep an ailing system from a very well deserved grave (and criminals like Obama from the electric chair, but that is a different story).
What’s wrong with trying things yourself instead of trusting some paid shill? Please explain.
Suit yourself… It’s funny you tell me “Need to change your mindset “, coming from someone who prefers someone else’s opinion to their own. Are you a bot or a real person?
MATT GRAINGER = ZZZZZZZZZZZZZZZZZZZZZZZZZZZz
Why are you promoting this clown admin?
did i miss something or can you tell me when he joined the circus.
Please post the link to your awesome video explaining the T Stop. If not your just T bagging the guy.
Quite a rude knowall aren’t we? You Matt’s bumfriend?
So. Matt rejected you as his bumfriend, hmm?
Yawn. This is even below average m43 nonsense.
This is a pile of DOG T.URD.
