Sigma 150-600 C vs S vs 300/2.8 II + 2xTC vs 100-400 II + 1.4xTC on 7DII

Interested in your observations Alan.
I have tried the Sigma 150-600 (not certain if it was the "C" model) and found that it didn't stack up too well against my 300 F2.8 L IS Mk1 + 2 x Mk3 extender. However, for the price, I was rather impressed by the Sigma! Perhaps it wasn't a C model that I tried?
I cannot speak for the relative merits of the IS systems as I don't use IS - well not since January 2014 anyway.

gary samples said:
can some one please give me some schooling on focus screen replacements for my 5ds
do they make one that will work for the Otus & my canon lens
I see canon says
(fixed) on the screen Thanks'
Gary,
You'll find some info on this thread. The focusing screen on the 5DS/5DSR is not the same as the 5DIII, as is explained in the thread. I have contacted www.focusingscreen.com and asked if they will make an S-type screen (I have theirs S-screen for the 5DIII). No reply yet.

So unless you have the guts to do as Zeidora (I don't) there is not much to do but wait ...

Maybe you get your A7RII first and the manual focusing issue will be solved......(via an adapter). And you will be able to gain a few stops via the 5 axis stabilisation + the dynamic range.

A cheap 10D - ??

rhysb123 said:
The question - what are people's thoughts on the 10D and does anyone still use one?

It was my first DSLR, and have it till this day. Was using it untill end of 2014 but the batteries gave up (after 11 years!!), I have it gripped and had 3 original batteries.

All I can say that it was great camera and its IQ was great for many years, it is heavy and tough as a brick :). I used it for macro shots and landscapes.

DPReview's turn to beat up the 5DS/5DSr results

I, for one can't wait for the day a camera sees what my eyes see. Who cares about 50MP when you can't take a photo of a person next to a window with a view of a bright day and you have to decide if u want the camera to measure the person or the background. If u choose the person, the background will be all white and blown out. If u choose the background. Then the person will be too dark.
I hate that. No matter how expensive the camera or the lens. It's all about that DR.
Video cameras can "see" it all already. So why can't photo cameras?
I rather go back to 6pm with the DR of the human eye.

5dsr Dual Card Slot Potential Issue

I have shot since Tuesday about 1600 frames on my 5Dsr with two 32GB Lexar 1066x CF cards, both new and formatted in Camera body. No issues, but not doing the dual card set-up (yet).
32 GB is a bit small for the 5Ds, only about 4xx RAW files, I think I will get at least one 128 GB card.
On the upside, the new Canon software to download images straight from body does no longer crash after 200 images as on the earlier version from the 5d2.

Any News On Canon 50mm Image Stabilized Lens ?

Crosswind said:
The only reason to upgrade from my 50 1.8 STM to a 50 1.4 STM IS would not be the stabilizer but a lens design which prevents comatic (not chromatic) abberations. I guess this is wishful thinking as coma correction is only something for Canon's L-series... rrrright?
I have a few L lenses and they all suffer from coma at maximum aperture, even the expensive ones.

Canon 5D mkIV pixel count

Pitbullo said:

Pitbullo said:
My bet is 32mp for the 5dmk iv, since 32 is easily scalable with 4K resolution.

4k means 4096pixels wide, on a 1.5:1 w/h ratio that's 11.18Mpix. double that scale in each direction and you get 44.74Mpix

Rather close to the a7rII.
My thoughtnwas that 4K was approx. 8 mpx, multiplied by 4 = 32.
I didnt think of aspect ratio. Perhaps 42 is the count for 5D4 then :)
Yes, because obviously there is a need for a 42 and a 50 Mpixel camera...

Sony to Raise Nearly $4 Billion, Ramp Up Sensors Business to Anchor Turnaround

Canon Rumors said:
Japan’s Sony Corp plans to raise nearly $4 billion via new shares and bonds to plough into image sensors as it reinvents itself as a niche component maker, pulling back from consumer goods like TVs that dragged it into losses.

They transferred personnel from the LED backlit TV to the backlit sensor... Major drag (into new losses). If Canon starts to make TVs I wonder whose technology they will borrow. ;D

Meanwhile I don't suppose this rumored Canon Foveon turns up in the 1DXII/5D4. If there's one "new technology" I'd bet on this one.

LensTip review of the 50 f/1.8 STM

FYI on LensTip's review of the 5- f/1.8, which dropped yesterday:
http://www.lenstip.com/index.php?test=obiektywu&test_ob=444

For the sharpness nuts, here you go:

Old: http://www.lenstip.com/424.4-Lens_review-Canon_EF_50_mm_f_1.8_II_Image_resolution.html

New: http://www.lenstip.com/444.4-Lens_review-Canon_EF_50_mm_f_1.8_STM_Image_resolution.html

I toyed with making an animated gif of the two charts for a quick reference, but just toggling back and forth between two browser tabs should do you.

Looks like center sharpness is unchanged through the aperture range, but corner sharpness gets a nice bump through most of the business end (f/1.8 - f/8) of this lens. Nice work, Canon.

Some 5DIV talk over at NL

"A report (thanks) of 5D4 testing, where there is still a mix between 18 and 24MP. 24MP is the likely final outcome, with the lower MP sensor testing AF speed and buffer management issues (less than 8FPS is the likely shooting speed)"
Keith's point to that: If this is so, then it suggest that the 5D4 launch is still some way off?

5dsr keep mirror locked up over multiple exposures?

Zeidora said:
P. 266 of manual notices, that silent LV shooting is impossible with flash, and that when flash is detected it will automatically disable Silent LV shooting.

Now that you mention it, I think many of the more recent cameras do that. The catch is that they only do so with a Canon flash, so you must change the setting manually if using a third party flash. IIRC, there's a note to that effect in the manual.
