Everlast66: Sandisk is my favourite brand of SD cards. It would be sad if WD ruins them.
There are statistics on HDDs published by Backblaze. While WD hard drives are not reliable as Hitachi (HGST now), they are much better than Seagate. Basically, if WD survived for the first 3 months, then it will last a long time.
RolliPoli: This thing makes me want a new button for: "I Don't Want It" in the 'Gear In This Story' panel!
@Stollen1234: Really ;)@Just a Photographer: I do not get your point. I certantly do not envy people that have money and spend them on "luxury" cameras. I'd rather have my current more or less average income than be rich and stupid. Camera is just a tool. Luxury cameras are just as stupid as luxury screwdrivers.
@Just a Photographer: It seems you need that button more that he does.
ShoppingBoy: Thanks for this exciting news. Apple are probably the top innovators in photography today. I'm looking forward to growing with them in the coming years.
Now that is trolling :)
It's not trolling, it's sarcasm.
Felix11: I don't follow the logic of this:
"The lack of colored filters increases the amount of light that reaches the photodiodes compared to a filtered sensor,"
..makes sense so far, but then ...
"and thus the lowest ISO setting the camera offers is ISO 320"
Firstly, to avoid confusion, does 'lowest' ISO setting mean small value, less sensitive, closer to 100? Yes? Good!
In that case shouldn't the lowest setting be less than competitor cameras?e.g. 200 ISO is a common lowest value on APS-C models, and 100 ISO on full frame models.
If more light is able to get to the sensor due to the benefit of not having a CFA then a less sensitive setting (i.e. lower) should be required to avoid over exposure.
Please explain :-)
ISO is just a number which ADC uses to amplify the signal by. Lowest ISO setting usually corresponds to the amplification factor of 1. You can go lower than 1, but I see no point in that.
Vitor hugo: EDIT: Nevermind, someone had the same idea as me in the comments.///What would happen if one: 1) get this camera on a tripod 2) get 3 color filters (Red Green and Blue) 3) takes one photo with each of those filters 4) stacks the resulting pictures as RGB channels in PS?///
I'd prefer sensor shifting like pentax k-3 and hasselblad have. Much less hassle with vibrations and time between shots.
Tom 13: A stitch in time saves three thousand three hundred and ninety nine.
You are right about me not being intended buyer for this - I want UWA only rarely. But you are not going to compromise quality by using APS-C this way. You can probably get even better results because you will use several cameras, which means not only more resolution, but also more sensor area used.Personally, I find stitching acceptable on some occasions. It doesn't take much time on a good computer.But I agree, if UWA is someones favorite style then this lens is a nice addition.
Why do you need 6D for that? APS-C will do just nicely. And pretty much every professional already has some backup camera(s). Sure it is inconvenient way of taking pictures, but if you do not take very wide FOV pictures very often it is better than paying $3000 in my opinion.
Well, it is possible with some editing. Another possibility is to use several cameras at once which would probably still be cheaper.
FRANCISCO ARAGAO: The potential for disaster is enormous.
@AlexisH: And the point of regulations is not to completely eliminate risk, but to reduce it to acceptable level. There still will be disasters, but not as often if not regulated.
Sure, airplanes and automobiles are also dangerous. But you do not often see airplanes flying over people heads, do you? Or automobiles driving though parks full of people?That is because they are regulated by laws and rules.Besides, drones are very loud and annoying.
Raist3d: So sad to see Russia doing this. I hope the rest of the world can serve as a living example of why this is ridiculous.
I live in Russia. I care about gay couples about as much as straight ones - not at all. It is not my business and not my life, they can do whatever they want as long as it doesn't interfere with others. Same true for all. "The right to swing my fist ends where the other man’s nose begins."
@D1N0: About US political system: there would be so much less trouble in the world if US would simply care just a little bit less for things like gay rights in OTHER countries. US very easily imposes its own way of life to others, but doesn't want to take any responsibility for it.
@Raist3d: and you should probably read less news ;)
Jonathan Lee: would it be full frame mirrorless and take k mount? i would hold on buying the other brand's FF mirrorless.
And waste 40mm of space inside? Much better choice would be some-other mount mirrorless body with K-mount adapter.
LBJ2: "which offers a fast maximum aperture of F2.8 throughout its zoom range"
Applying the crop factor, is this new lens really an equivalent f2.8 "throughout its zoom range" or is it really equivalent to 24-83mm f4.2 ?
I see it that way - when you press shutter button, what your camera does - is simply collecting light. And in the end, all that matters is how much light you've collected. And that is defined by shutter speed and aperture diameter (focal-length divided by f-stop) and maybe sensor efficiency too.
Well, maybe we a bit off on semantics then. I understand light gathering capabilities as "how much light in total goes through this particular lens". Not how much it projects per unit area. I simply don't see how "per area unit" fits in "gathering" - you either gather it or not, doesn't matter how you will project it afterwards.In the first case, f2.8 is not f2.8 across different formats. In the second case, I agree, f2.8 is f2.8, but then you still have to consider different sensor (gathering) areas as separate argument.
Exactly - to gain exposure! If as you say we assume DOF is not considered here, then why bother with f-stop at all? Just use higher ISO setting to gain exposure. Only you would use larger aperture rather than ISO to gain exposure because with larger aperture you will gain more light and have less noise, and that was my point.
Original question was about light gathering capabilities, which is not exposure, because lenses for bigger format will gather more light at same f-stop.
But you can easily have same brightness by changing ISO setting. And have two photos that are equally lit. Why bother with f-stop at all?
Ok, why do you want to compare same exposure?
Total Light = Exposure x Sensor Area. You cannot ignore sensor area if it is different. Same f-stop will produce different result on different formats. If total amount of light was irrelevant, then f/2 on my tiny mobile phone camera would have been same as f/2 on full frame. It is not. Full frame gets more light -> more signal -> less need for signal gain -> less noise and more DR.Brightness however is irrelevant, as digital sensors have only one real sensitivity value and most cameras today use "isoless" ADC (except maybe for Canon), which means that noise produced by them will be the more or less the same regardless of ISO setting. You will get similar results by increasing exposure in post-processing. You can check it yourself by taking two pictures at for example f/4, 1/500, ISO100 and f/4, 1/500, ISO800, and then increase exposure in post by +3 for ISO100 shot.
