A guy on a moto in Vietnam. I took a series of photos and he had his eyes closed in every shot  :o

I think this just makes life a lot harder for the potential buyer. What to buy? Do any of these optimise what a standard Zoom should offer??

I still think the 17-55mm F2.8 offers the best all round want from a photographer for a standard zoom range. But they dont make one for full frame which would be the 24-70mm F2.8 IS.

24-105mm F4 is a great focal length for a walk around lens, It is also not a bad price, good IQ and has IS.

24-70 F2.8 is in the stratosphere for most in terms of price. Its really ridiculous it would take nearly two weddings to afford the purchase price.

Wouldn't IS on a F2.8 make it a great walk around lens? Yes you loose 35mm but this would make it more useable in low light, 1/30th and below is the norm in low light trying to balance ISO with quality. So this would be stuck to your camera most of the time, and means you dont have to jump up the ISO.

Except losing the f/2.8 for some AF points, the 24-105mm f/4 IS is the FF equivalent of the 17-55mm f/2.8 on crop, but better, in focal range and DOF ;)

Lenses / Re: efs 15-85 or ef 24-105L
« on: October 24, 2012, 10:37:40 AM »
both are 30% off of refurbished price and within 10 dollars of each other at canons online store.

both have great image quality
both have IS
one is lighter
the other is weather sealed(I think ?)
one has a longer reach on the aps-c censor
obiously the efs is aps-c only

So which would you pick?

I'd choose the 15-85. I had the 24-105 paired with the 1D IIN. Then I sold the 1D and got the 7D with the 15-85. For a short moment I had the 24-105 and the 15-85 at the same time. I sold the 24-105 and kept the 15-85 as it is better for me with the 7D. I've just got the 17-55 f/2.8 and I think I will sell the 15-85.

Can someone please calculate and compare the surface areas between the orange and red lines because I'm still not convinced when and how to interprete those graphs and which sensor is better and when?
DxO measurements is a bullshit if they can't provide the simple math formulas to calculate the integrals. I'm so dissapointed...

Euh, I don't see any reason to calculate the surface areas between the lines in order to know which sensor is better and when.
Just have a look at theses graphs again and forget everything about integral.

<sarcasm off> :D

Anyway - the bigger the area in either low or high iso part of the graph, the bigger the difference between them there and the simplest way to calculate this area are integrals when you know the math formulas. But anyway it was just to cheer you all up in this serious discussion...

Haha, thanks  ;)

But...it really doesn't matter, so I'll not continue to respond to your obviously specious statements, because:

D3x sensor is the same as in  the Sony A900, there has been much discussion whether it is a 12 or 14-bit column ADC and if Nikon has changed it  . In  the Sony's sensor is it determined that  is a 12-bit  column ADC.

Ok, so Nikon says it's 14-bit, but you say Nikon is lying and it's actually 12-bit....


@generalstuff: you should do more research before jumping on any conclusion. The Sony A900 has a 12-bit ADC does not mean that the sensor is limited to 12 bits! It means that Sony only includes a 12-bit ADC in their A900.
BTW, the Nikon D3X has a max of 5fps in 12-bit mode (Nikon specs) and of about 2fps in 14-bit mode (estimation).

why would he say that when it is not the case.. i mean it´s stupid that he admited that at all.

the reaction on this is 95% negative.

... and the same 95% are not the target market for these two cameras  ::)

ho-hum

I think you don't think so because you read DPR too much.   ::) 
Busted  ;)

Thanks neuro! I was the first in this thread who talked about no AFMA with the D600  :-[

55
No AF micro adjust. Max flash sync 1/200s. Max shutter speed 1/4000s.
For the price, I would get the D700 instead. Better everything (for me) except (arguably) the sensor.

I certainly wouldn't say we are "firmly" in the realm of diminishing returns. I think Nikon and Sony proved that with the D800's sensor. It not only added considerably to pixel density, it improved the quality of those pixels as well. A 36mp sensor has 4.6 micron pixels, which are LARGER than the 4.3 micron pixels of Canon's 18mp APS-C sensors as well as the new 24mp sensors used in the D3200. Again, Sony and Nikon have demonstrated that a 24mp APS-C sensor, which is pushing 130lp/mm in terms of spatial resolution, is also capable of not only having more pixels, but pixels of higher quality.

The question is not whether Canon can produce a high MP sensor. The question is whether Canon can compete and produce a high MP sensor with BETTER QUALITY PIXELS than any of their current sensors, including the 1D X and 5D III. By eliminating almost all noise in Exmor (there is only about 2-3 electrons worth...not much more to remove), SoNikon have basically set the stage...the only thing LEFT TO DO once you perfect the pixel is pack more of them in.

Waw, after you, pixel quality = pixel size  :o ? Do you know that the sensor of your 7D have a pixel density equivalent to a 46MP FF sensor?

Except with a 2x converter on and on a crop body that is 3.2 equiv  ;)

I disagree. The subject won't be 3.2x of its life size on a crop sensor, only 2x.

Technical Support / Re: EOS Utility

Not my favorite tool to download pics to my mac but kinda bootlegged with a memory card reader for my LExar 1000x 32gb CF card is on its way....i m connecting the camera to my mac to download pics and EOS Utility seem to be the only way to do it at the moment as My LR3 program wont recognize the new raw files. (Although photoshop does).

To add to the pain updated Lion to MLion and EOS Utility crashes. Any one facing this issue ?

I lost my card reader last week so I was forced to use EOS Utility to download the photos to my Mac (with Mountain Lion). I heard about EOS Utility crashed on Mountain Lion with version 2.11.1 and newer. Up to version 2.11.0 it works fine. I installed version 2.10.4 and it's ok for me.

Version 2.10.4.0 works fine for me on Mountain Lion OS X 10.8 (12A269), MacBookAir4,2
Same for me! I heard that EOS Utility works fine in Mountain Lion until version 2.11.0.

If it uses the 1D4's AF system unchanged, it will cover a relatively smaller area on FF (unless they scale it up, in which case it wouldn't be the 1D4's system).

Possibly it will use the 1Ds3 AF

As I said in another thread, I think that all the 1 series up to the 1D4 have the same AF surface of 8x15mm with 45 focus points (the EOS 3 was the first to have these characteristics). The Canon expands this surface to 8x19mm for the 1D X. I am quite sure that my 1D2N has a larger AF coverage than the 1Ds2 which has the same AF system.

Brian, as you own both the 1D4 and the 1Ds3, can you confirm this information? Thanks!
