Lenses / Re: True reach of 100-400 L II
« on: February 28, 2015, 10:56:52 PM »
http://www.the-digital-picture.com/Reviews/Canon-EF-100-400mm-f-4.5-5.6-L-IS-II-USM-Lens.aspx

Brian at TDP measured the focal length of the 100-400ISMkII from 42 feet as being 383mm, that being the case it doesn't look like you have to go too far away before you get very near the specified focal length.

I'm betting they had to make some concessions to get the incredible Maximum Magnification that they do, but as someone who takes pictures of small things as often as large the trade off is definitely be worth it for me.

It's funny how the 400f5.6 is still (still still still, lens after lens none of them are solidly better, I feel like I'm going to be saying this for the rest of my life) the best lens of its type on the market. If you don't need the zoom and want to save a grand definitely get one of those.

There's always the things that a phone camera physically can't do.
Sports and wildlife.
Lowlight
Macro
Bokeh

I honestly don't think the enthusiast market is going to shrink, but we've all known that the P&S market was dead a long time ago, so that's just stating the obvious.

Canon General / Re: Do More Mega Pixels translate in a richer photo?
« on: February 27, 2015, 05:16:27 PM »
I actually think that my 4MP computer screen is about halfway from giving the full detail in a 14MP image (produced by the T3/1100D).
My guess is that you only need half the screen resolution to effectively see everything in an image due to the Bayer filter and AA filter (for now I'm just going to pretend that all sensors have one).
So viewing those pictures on a 4K monitor (8MP) should be as good as looking at a high quality full resolution print.
Once we have 5K monitors your 5D3 isn't even going to fully saturate the image a PC is capable of out -putting.
Right now I can't tell the difference between a T3 image and 5D2 image when both are fit to screen, but the sad reality is still that we need to massively oversample images to get the same quality per pixel seen in other formats.
Once 8K hits the market even the 5Ds is only going to be barely good enough.

On a full resolution print it should absolutely make a difference, I just need to print something before I can say for sure.

EOS Bodies / Re: Possible Canon EOS 5D Mark IV Spec Talk [CR2]

I still wish they had just stuck the 5Ds sensor in the 1Dx body, I want the resolution along with the huge battery and integrated grip (more stable on a tripod).
But I also want wi-fi and a touchscreen.
Sigh, now that they have a 24MP sensor, chances are the SL2 is actually going to be the best body for me (whenever they get around to it).

The 50MP sensor??  I wont say it's impossible, but it's pretty far down the pecking order of probability.  That was a sensor they obviously tuned for low ISO, not the end all be all action sensor.

Give me a 1DX2 with a mid 20 sensor, 14fps, an absolute criminally insane number of AF points that can focus at f2, and make 12800 ISO look like 3200.  There's your unicorn list.

I guess a simpler way of putting it is "1DsIV".
ID body with landscape sensor. But yeah probably not going to happen.

Lenses / Re: My "Minimalist" Lens Arsenal on Crop?
« on: February 21, 2015, 11:30:29 AM »
My current plans are to use the Sigma 18-35, Sigma 50/85/135 Art (depending on a variety of factors once we can compare them all), and the 100-400II (because I like shooting wildlife).
Honestly I could do without the portrait lens, but sometimes it's nice to have the option of using bokeh to hide the background.

My one repair experience with Canon was very positive, they thoroughly understand the importance of customer service.
It's not uncommon to hear about that being the differentiator between market leader and "the rest".

Lenses / Re: APS-C 60mm or 100mm macro lens?
« on: February 21, 2015, 11:00:27 AM »
I love my Sigma 150mm macro, the extra working distance is great. Like with any telephoto, you can shoot handheld as long as you keep your shutter above 1/1000 (which normally requires daylight).
The only 60mm macro I would consider is the one with a 5x zoom, I've spent too much time bumping into things trying to get close to bother with shorter focal lengths anymore.

Well I loved the questions about the 400DOII, at least he got a bit insistent there. That was the highlight for me and hearing that the IS is so good on that lens is certainly making my wallet nervous.
I probably should get the 100-400f5.6 first though, I would use the close focus a lot, and after seeing the build quality I'm much more optimistic about the value of that lens.

Third Party Manufacturers / Re: Sigma 85mm f/1.4 Art Lens Next? [CR2]
« on: February 17, 2015, 10:37:59 PM »
Too bad they've abandoned the 24-70 f2.0 for the 2.8.  I personally think it would sell *better* due to unique value. Sigma's selling factor isn't only price, but also making lenses that simply don't exist anywhere else, like the 120-300 2.8, the 18-35 1.8, the 50-150 2.8, the 50-500, 200-500 2.8 :P, et cetera. Sigma already discovered with the 24-105 that the midrange zoom market is flooded, why keep trying to make something everyone else already makes?

I think quite the same, I don't understand why Sigma isn't focusing onto formulas no other produces. I, for instance, would consider a new 20mm f/1.4 ART (if that is doable, otherwise f/1.8) much more interesting than the 24mm they released recently. If I want a 24mm f/1.4 I can get that from Canon or even Samyang (if I want to get it cheap). No unique selling point in this formula. Sigma, please, bring on something outstanding.

I mostly agree but a unique focal length alone isn't what makes these lenses popular. I thought with the 35A
and 50A that they had figured out sharpness sells, and when you combine that with a world record aperture
it flies off the shelf (18-35A), the 24-105 was not sharper, cheaper or faster than the competition, anyone
should have been able to tell you it was going to bomb.
The only caveat here is we haven't seen a Sigma Art lens for more than $1,000 yet, so whether or not a
24-70f2 would sell well at $2,000 is still a good question. $1,000 is a huge mental barrier and Sigma would
have to nail everything down perfectly to sell a lot of those even with a world record aperture.
I think they're right to be pessimistic about an expensive wide aperture zoom, if their design estimates
weren't turning out good sharpness it may be for the best, but I would dearly liked to have seen another
crisp wide open f2 zoom lens.

And they also allow you to bump up the fps (errr.... well so long as you don't shoot Canon) since there are less MP to process making the cameras much more all-around (again, Canon alone can't dare have that though)!!

Ironically, unless firmware has changed recently, the D750 does not give a crop mode boost, Nikon only wants to make sense when you pay them extra for it.

Third Party Manufacturers / Re: Cheating - feeling guilty...

I'm still waiting to see how the shootout goes between Fuji and Samsung. Fuji has a 400mm zoom in the works and Samsung has a 300f2.8 prototype that they have shown, and both of them are only on their first generation sports body. Gen 2 should be much better.
It could go either way, Samsung has an amazing sensor and I love Fuji controls.
Hopefully they just merge the internals of the NX-1 with the shell of the X-T1 and call it the "MK-1" (the "Mirror Killer").

I'm not terribly impressed with the optics (a good improvement, but not great), but after seeing this, I want that lens.

Canon should send Roger a cut when he does these.
