Barred buttonquail (Turnix suscitator) by alabang, on Flickr

A typical Barred buttonquail or common bustard-quail (Turnix suscitator), rufous-brown above, rusty and buff below. Chin, throat and breast closely barred with black. Female larger and more richly coloured, with throat and middle of breast black. The blue-grey bill and legs, and yellowish white eyes are diagnostic, as are also the pale buff shoulder-patches on the wings when in flight. Absence of hind toe distinguishes Bustard and Button quails from true quails. Pairs, in scrub and grassland.

Unlike other buttonquail, are not as difficult to see, since it tends to cross, or run along, savannah tracks, and is readily viewed from a vehicle.
Feeds on insects and seeds, and is reluctant to fly.

The calls are a motorcycle-like drr-r-r-r-r-r and a loud hoon- hoon-hoon.

EOS Bodies / Re: A New EOS Pro Body With 46mp Next Month? [CR1]
« on: September 18, 2014, 12:11:44 AM »
If they move to CFast memory cards then the read/write limitation of CF cards wont be an issue for a 46MP body with a high continuous shooting/burst rate.

Although those CFast cards are sure are expensive. ATOMOS 64GB 200MB/s read * 80MB/s write CFast card goes for $160 while Lexar 256GB 510MB/s read & 370MB/s writes goes for $1300.

My sole beef with built-in extenders is that they add length to gear. Sometimes space isnt an option especially on handcarry.

OT: It could be interpreted as conflation but my conclusion isn't so.

There is already a DO lenses that could also face replacement. Saying more DO lenses are to follow could hurt sales of that lens.

No other than Chuck Westfall confirmed it. As to when we can expect a 100-400mm DO was not answered.

Hello Osbourne Effect.

Nowhere does Mr Westfall or the article state the 100-400 will use DO.
If I understand the article correctly, there are two issues- replacement of the aging tele zoom, and developing DO and bringing the tech into cheaper lenses.
Thanks for the correction!

Samsung is a big enough gorilla to take on Canon, Nikon and Sony. More power to them as it will only drive Canon to give better products at better price points

EOS Bodies / Re: How can we improve on 5D3 to 5D4?
« on: September 16, 2014, 04:54:48 AM »
Of course, whatever works for a professional, he or she will use it- these rigid boundaries are merely theoretical.
I am not very familiar with CFast. They seem to have been around for a while, why hasn't any major manufacturer started using it yet? What about the Nikon XQD cards?- I believe they can write as fast as 500MB/s (the newer version might be even faster)
CFast is the designated replacement for CF cards. CF cards are based on the PATA bus so are constrained to 167MB/s of UDMA 7 spec. Now CFast on the other hand uses the SATA bus that is currently limited to 600MB/s

4K resolution video cameras that currently use CFast are those from ARRI and Black Magic Design. ARRI Amira allows for up to 200fps vs the more standard 24p/30fps/60fps 1080p video we are more familiar with.

It is very much possible that we'll be seeing SLRs with CFast next year or 4 years from today. There is still some wiggle room with CF cards at say 1100x? Speeds of current CF cards top 1066x and are hella expensive.

While not as fast as the CFast, SDXC UHS-II cards can now reach 250MB/s write speeds.
SD form factor is suitable for consumer and space-constraint application.

CFast form factor is suitable for professional/prosumer.

I can see UHS-II cards being used on the successor of the 6D, 70D, 700d, etc but for 1D, 5D and 7D bodies it makes more sense to go CFast.

UHS-II is constrained to 312MB/s while CFast is 600MB/s.

Still disappointed that the 35/1.4L, 135/2L, 180/3.5L Macro and 400/5.6L are not replaced yet.

Have better specs than cameras from Nikon, Sony, Panasonic, Fuji and other brands.

Ditch CF and SD.

Go CFast that exceeds the 167MB/s limit of CF cards. SD cards should be the province of the 6D only.

EOS Bodies / Re: More Images of the Canon EOS 7D Mark II
« on: September 15, 2014, 06:22:21 PM »
7D Mark III will be announced September 2019 before Photokina 2019. Bodies will ship November 2019.

5D Mark IV will be announced March 2015 or later. Bodies will ship weeks later.

Disappointments with the 7D Mark II:
- No WiFi (May be a reason why there's a SD slot for EyeFi)
- No 4K resolution video
- No CFast memory card slot for faster than UDMA7 reads/writes of 167MB/s.
