Lenses / Re: Which Sigma Lense?
« on: January 25, 2015, 11:37:42 AM »
Nice shots.

The 18-35 f/1.8 is so cool it is hard to get excited about the 17-50 2.8 lens. 

You have a 50mm prime for when you need 50 mm.

I would do the 18-35 1.8.  With a crop sensor you cant use ISO's as high as on full frame with as good an image quality.  The wider 1.8 aperture buys you an entire stop of light you can use to get decent shutter speed wih tout having to use the higher ISO and the IQ penalties that come with it. 

And at wide focal lengths like 18-35 you keep a pretty thick depth of field, so it is much more practical to work with than a more razor-thin DOF you'd get on a 50 or 85mm lens wide open at f/1.8.

How hard can it possibly be to use a non -Bayer pixel pattern like Fuji does?  My understanding is Fuji just made the pixel pattern less simple than the little repeating 4-pixel blocks in a Bayer pattern that give us this problem with screen doors/fabric/etc., and this makes the low pass filter unnecessary. 

It seems fairly straightforward and not subject to any patent issues vs. Fuji. How could anyone patent "any pattern in the world other than Bayer"?

Note that as a result of using a non-Bayer array, Fuji's cameras have more limited 3rd party support for raw image development than do Bayer array sensors.

That is a good point. I had not thought of it. 

HOWEVER, Fuji is Fuji.  Canon is Canon. Adobe always does the quickest updates for Canon cameras.

Yes, I am bumping my own question.  I don't oftrn do that but I really wonder what others think of the question.  If they omit the filter, there are compromises.  Why not go the Fuji  x-trans route and use a less simple pixel pattern?

Software & Accessories / Re: 10 bit graphics card ??
« on: January 23, 2015, 06:20:50 AM »
Yes because you'll need display port for 10 bit and they restrict 10 bit to the pro cards. However there is a hack to trick some Nvidia cards into believing they are quadro cards and getting them to work in 10 bit mode. It's not for the faint of heart.

I may be not reading this right. My GeForce GTX 770 does have display port.  But I thought it cannot do 10 bit color from what I've read.  Is your post saying it can because it has display port?

Try B&H online, for the searchability, if you have not already.  They have a great set of filters you can set to winnow their enormous selection of backpacks down to just the ones that fit your needs. 

The downside is that if you have any OCD tendencies you can easily get vapor lock in the brain from over analyzing the many choices.

I carry a 70-200 around on my camera quite often and I find the Luma Labs Cinch Strap does a great job.  No pain I have ever noticed and I find the fact the thing is attached to 2 points on the camera makes it more stable. It cannot twirl like it can if dangling from a single point like BR and most other shoulder straps use.

Software & Accessories / Re: What monitor????
« on: January 17, 2015, 03:06:42 PM »
I wonder about the Dell UP 2414Q also.  I looked it up on B&H after someone above recommended it.  There was one weird comment/review from someone that said it makes the text appear so tiny that they only use the monitor for photo editing.

Why would that be, and is it nonsense?  Supposedly if you set the text size super large to compensate it then messes up on website layouts.

Software & Accessories / What monitor????
« on: January 16, 2015, 11:07:53 PM »
I am finding it hard to get my head around which monitor to buy.  I cannot spend more than $800, and if i can get away with it I would like to keep it to more like $500.

I guess I need an IPS monitor. (Right?) 
I do not want a huge one; a 24 is fine, probably perfect.  A 27 would be the very largest I would want. 
A refresh rate that is not so slow I can't use it for the occasional computer game would be nice.
I have a pretty new NVidia video card (GTX 770), but I think it will NOT do 10 bit color per channel; only the Quad Pro cards do.  (right?)

I really want one that can be properly calibrated.  I have a Spider Cal but I am not any expert at using it.

I found one that seems good but some people say some units emit a "squealing" sound that is bad.  http://www.bhphotovideo.com/c/product/974400-REG/asus_pa249q_24_led_backlit_ips.html

Any recommendations?  Thanks.

Do check out the Luma Labs Cinch Strap. 

http://www.1kindphotography.com/2014/01/review-luma-labs-cinch-2-camera-strap.html

It comes with an arca-compatible plate with an attachment point build in so you can put it on your tripod without taking the strap off.

It attaches at TWO points on the camera, not one like the BR and the others, so the camera cannot twirl and dangle but remains against your body.

And of course it has the "cinching" ability, which lets you lengthen it for shooting or shorten it for carrying just by sliding the buckle thingy.  Very very handy.

I love mine.

Lenses / Re: New Rebel & EF 11-24 f/4L USM Coming Shortly
« on: January 16, 2015, 11:01:19 AM »
I dunno. 

The Nikon 14-24 is an f/2.8 lens and this one isn't. 

And the Nikon costs $1,999.00 and this one is $3,000.00.

And the Nikon is well-regarded from everything I read.

Can this thing really be 150% as good?  Or if not, can the Canon shooters be desperate enough for this particular lens to pay this much more than Nikon shooters simply because they have to?

EOS Bodies / Re: A New xxD DSLR Coming From Canon [CR1]
« on: January 12, 2015, 06:08:31 PM »
It is way too soon to be an 80d.

It is a little hard to imagine them cramming something I between Rebel and xxD because there isn't all that much difference.

We are kind of due for T6i, by the time this could appear anyway.

Canon also said recently they were done doing tiny irrelevant annual upgrades, so maybe they decided to beef up the T6i. If Canon can't beat SoNikon on sensors, there are lots of other features it can enhance easily. It can certainly throw in an LCD screen and a simple wheel for cheap instead of some colossally amazing (non existent) new sensor. Why not?

EOS Bodies - For Stills / Re: Wait for 5D4 or go for 5D3/6D right now ?
« on: January 10, 2015, 10:48:27 AM »
You don't say what you shoot and you don't say what your 400d/Xti lacks.

If you are getting by with the Xti you probably don't need the 5d3.  It offers a complex autofocus for motion/sports while the 6d's is more basic (though not as basic as the 400d). The 6d, though, is actually better with it's center point at focusing in dim light.

If you don't spend the extra portion of your budget on the 5d3 you can put it to good use on lenses.  Better lenses will make a bigger improvement in your photography than will better bodies. 

What lenses do you have now?  The biggest expense in going from crop to full frame may be getting new lenses.  The FF won't use EF-s crop frame lenses at all, and if you have not yet spent some money on good quality lenses you would do well to go cheaper with the body so you can buy some good lenses that won't hold back the performance of a new body.  Mediocre lenses won't give great IQ even on an expensive body.

Canon General / Re: Weak Yen Spurs Canon To Bring Production Home

This decision will appear very short sighted the first time Godzilla rampages through a production facility.
