If Canon did this, DXO would implode from having no one left to pick on.

They might have to start testing cameras rather than sensors.

i think thats beyond their ability

I agree with you about the 24-70 2.8 on a crop sensor. You won't be able to get as shallow depth of field with a crop señor as with a ff. I think that's the point he's tying to make that you geting more like a f4 depth of field compared to a 2.8 on ff. But yes you still get the light of a 2.8 lens on a crop sensor

Yes, I assumed he was referring to the greater depth of field on a smaller sensor not that it transmits less light. But, he didn't specifically say that as far as I can recall. I'm pretty confident that Northrup understands that.

I didn't realize that the ef-s 17-55 f2.8 was so highly regarded. I may pick one of those up if I can get a good deal on a refurb. Seems like it would be sharper then my 17-40 or 24-105 on the 7D2, which is not particularly forgiving of poor glass. f2.8 vs. f4 would be icing on the cake. I wonder how it compares to the new EF 16-35 f4 IS on a crop?
i think the new 16-35 f4 might be a tad sharper over the frame but not by a significant amount
but given the extra zom range the 17-55 gives and an extra stop of light its still the better choice IMO

I really don't get the hatred towards Tony Northrup. He makes good videos in my opinion and tries to be as unbiased as possible. He publicly admits when he's wrong. He's also quite level headed and the constant victim of internet trolls. He's just a camera geek doing what he loves doing. The funny thing is I never see people having a go at Kelby or Polin who just talk crap for 99% of their videos. Yes, I don't trust Dxomark either and think that their data doesn't represent reality, but can we stop bashing Northrup for a moment.
Don't even get me started on polin....
You tube is full of these clowns .... Northrup is particularly bad because he blatantly presents rubbish as fact which causes people who are trying to learn confusion and really he just talks crap for such a long time analysing numbers charts and spec sheets. Oh joy x manufacturer releases a specs sheet for new camera y immediately Northrup will trot out and hour long drivel fest going over the specs like he actually knows what he is talking about then he will proceed to making sweeping assessments as to good the camera is based on this rubbish.

Trouble is he believes his own press.

(As always, I post these hoping for a proper group skewering.  I eagerly await Neuro's rebuttal web-series, entitled "I am the anti-Tony", but it hasn't happened yet.)

To rebut, I'd first have to watch.  There are many things higher on my priority list than viewing Northrup's videos.  Watching paint dry and picking lint from my umbilicus are two things that come to mind...   :o

dont forget bathing the neighbors cat in the same bath you are in has to be a much higher priority too!

doing head swaps on group photos is very common to get 1 optimal shot from half a dozen or so frames where different people blink look stupid or whatever

if I was looking at getting a new 7D II and didnt have many lenses

I would get the following lenses
new 10-18mm IS canon  STM
sigma 18-35 f1.8
sigma 50mm art
canon 70-200 f2.8 IS mkII

as it is i have the eos-M and 11-22 IS which i use ALOT because the package is so small (really hope the next M gets the 7D2 sensor)

i use the 50 art mostly on my 5Dmk3 and usually carry around the 135f2L if i like something longer
I use the 70-200 alot less since getting the 135 however there are many situations the flexability of the zoom trumps the speed and sweetness of the 135 f2L

I also bet the 135 f2L would be a stunningly good lens on the 7Dmk2 although i've never tried it YET!

So, a 7DII with a 55-250 STM comes pretty close to a 7DII with a 70-200/2.8L IS II.   But...put that 70-200 II on a 5DIII and the IQ will soundly trump the same lens on the 7DII. 

and thats not even accounting for the massive AF performance differential between the 2 lenses and the 2 extra stops of light, panning mode IS on the 70-200 f2.8 .... ;)

as soon as i clicked the link and saw who it was i closed it

without even watching the video i can say its not worth the time wasted
the guy is an unmitigated ass clown

basically using full frame lenses on crop bodies work just fine

essentially you are "wasting" the outer part of the image circle which usually is not as sharp as the center
if you look at any lens mtf chart you will see the line drops off towards the right edge of the chart
basically with these charts the higher and flatter the line the better the optics and for crop vs full frame you truncate the graph at the line that represents crop instead of reading it all the way to the right

then there is the AF performance of f2.8 and faster lenses with canons high end af systems like the 5d3 1dx and 7d2 which perform better than slower lenses

so in summary a great lens like the 70-200 f2.8 is still a fantastic lens on crop (i regularly use my 135 f2L on my eos M and its AF is great even on that camera)

be cautious about listening too much to these youtube vlog clowns that really struggle in the Intellect department.

if your macbook pro still only has 8GB ram its easy to upgrade it to 16GB yourself

a few years back i saw an ad on gumtree a mother who had a autistic kid that was super keen on photography had an ad saying her son broke his telephoto lens 55-200 or whatever it was maybe the old 70-300 and was asking if anyone that had one to give him, i was ordering my parents a new 600D for xmas and order the kit since it wasnt much more than just the body and gave the kid the 55-250.

this sort of donation I like, i met the kid when i gave him the lens in person and he was soooooo happy it was worth it just to see that.

Handing over cash to people asking for it no matter what method they use i loathe and refuse to participate

this is actually a decent shot but worth that much money?  :o

anyway its alot better than most of his other attrocities, anyone remember the moon shot where the clouds are behind the moon which he claimed was a single capture? not to mention the preposterous size of the moon in that one?

but good on him for selling it for that much dough...

Surapon would take the business end of a large silicone spatula from a discount store, use a blowtorch or even a gas range to melt it into the perfect shape, then Velcro it to his flash.

But for the rest of us mere mortals, this looks pretty cool.   :)

ROFL thats sooooo true

Lighting / Re: 72" umbrella... what to look for and what to avoid?
« on: December 03, 2014, 09:14:23 PM »
JD the 2 types of umbrellas you talk about light the subject completely differently from each other

the white shoot through is just that the light fire forward through the scrim and softens the light however it throws light everywhere so you have no control of the light.

this is great for lighting large groups of people say 3 speed lights on stands with shoot throughs like this along a front evenly spacedf for a big group photo works really well. for a single or couple its not so good as spill light goes everywhere and can reflect of all sorts of things.

the silver with black back you fire the light backward into the dish and have the dish pointed at the subject and the  edge of the light output is more defined and enables you to control the light better (you can get scrims and grids to soften and enable even finer tune for these in the form of umbrella softboxes. I have some phottix ones which are really well made the pack up nice and small, come with the scrim face and grid

i would recommend an umbrella softbox as a start like this

hope this helps

Right now, Samsung is eating everyone's lunch in the TV market.

Given their hold on the phone market, it makes you wonder about if Samsung applies itself properly to the digital camera market (especially the ILC/DSLR segment), what will the company achieve?

Will Samsung start to eat everyone's lunch there?

After their debut of the NX-1, maybe it is Samsung that Canon and Nikon need to be afraid of and not Sony.

The question is ... Why bother?  Its a declining market, a share of a ever smaller pie does not justify spending billions to develop new products and lenses.
Maybe their market forecast is different from Sony's ;)

Why did Sony buy Minolta? Anyway...

Maybe Samsung has a vision of people having a "Samsung Household."

Consider that Samsung also provide more of the other appliances you see in a house - fridge, dishwasher - why wouldn't they also want to offer a serious digital camera?
well it certainly looks like they hit the ground running with the nx1
what they really need is to partner up with a top shelf glass name like sony did with zeiss
