comment Is it assured that every type of lens will be made for a given interchangeable lens camera?
@PhilipKendall I disagree, there's no need to speculate in order to answer the question: no, it is absolutely not guaranteed that there will be one of each lens type available in the future! It is indeed possible for manufacturers to stop making a certain type of lens.

comment Stepping up my lighting for lego photography
@AndyM not every picture was done by submerging the bricks, just the snowy Hoth ones I think. The key to lighting the image you posted was a snooted hard light, shining through a tree branch in the presence of light haze, which creates interesting shadows and a sense of depth. The snoot also concentrates the light in the centre of the image creating a natural vignette effect which draws in the viewer. My advice would be: build yourself a snoot for your 430EX, create some light haze using hairspray or similar and experiment!

comment Why do medium format (digital) cameras capture better dynamic range?
Sensor design can also play a big part.

comment Why do medium format (digital) cameras capture better dynamic range?
It's a duplicate but I think the accepted answer on the linked question is wrong, simply put a bigger sensor collects more light, therefore more photos, which is akin to taking a political poll, the more people you ask the more accurate it is, more accurate = less noise = greater dynamic range.

comment Canon lenses with Sony A7r
@Bob The A7R has an issue with shutter shock when using long lenses mounted on a tripod via the lens collar (nothing to do with IS, which works just fine). It's probably not ideal for wildlife photography with superteles. Whether or not it's too slow in the studio depends on what you're shooting and how good you are at focusing. If you are reliant on autofocus then you will need to wait until there are more native autofocus lenses available.

comment Canon lenses with Sony A7r
@Bob Canon is waiting to recoup the investment in their current sensor fab or until they begin to lose a significant amount of sales before upgrading their 0.50 µm process to a 0.18 µm or smaller process that is required to be able to increase pixel counts without compromising on fill factor (and thus high ISO noise levels).

@BShaw the megapixel advantage is not huge, it's only 63% more, but the increase in dynamic range is much more significant: 428% (about 2.5 stops)

comment Canon lenses with Sony A7r
@Bob I did in fact just sell my 5DIII and managed to buy an A7R + Metabones adapter and still have money left over. It's a totally different shooting experience which is not for everyone, I'm using manual focus 99% of the time, and taking much fewer shots but at the same time not deleting any images that are out of focus or poorly composed. The resolution advantage is nice but not massive, unlike the increase in dynamic range. The reduction size weight is really nice too, but some will struggle with the ergonomics / controls if they have large hands or want to shoot wearing gloves.

comment Device to make continuous high-resolution photos?
@mattdm the question is relevant to timelapse photography now 4K is gaining traction...
