I just saw this video, over at Sonyalpharumors and I'm hooked ... I'll be ordering the a6000 soon along with the 10-18mm f/4 OSS lens ... my Canon G1 X is going on sale soon to make way for the a6000+10-18 lens

I get not wanting to attach a Canon zoom, but it's perhaps worth pointing out that you retain a small form factor if you attach one of the smaller Canon primes (I've used the 40mm pancake and 85mm 1.8).  Of course, focusing may not be fast enough....
I agree! ... I have been using it with 40mm, 50mm & 85mm ... I find focusing with 'foucs peaking' to be a lot more accurate and faster. Sometime in the near future, I do plan on adding the EF 24 IS, 28 f/1.8 and 35mm IS lenses.

Thanks for the tip. The only lens available as a kit lens in India is the 28-70  :(. The zeiss 55mm f/1.8 is almost 2/3rd of the Canon 50L price :o while the other lenses are coming soon >:(

Scrambled brain  ???
You may want to check out Amazon Japan (see the link below) ... they've got some awesome low prices (due to the weak Japanese Yen) ... I got my FE 24-70 f/4 from Amazon Japan ... you'd obviously have to work out your shipping and customs charges ... I didn't have to pay any shipping or customs charges, as my ex-boss brought it with him from Japan. Anyway, here is the weblink:

Thanks Alan,

@ f8 and smaller, Tammy shows better IQ in 600mm. This is good news for those want long zoom & shooting at slower shutter speed.

I'm no expert in BIF photography. Last time I tried, my shutter speed was in 1/2000ish.

F8 + 1/2000ish =  ??? IQ

I hear you brother!

The f/8 or narrower makes it a deal breaker for me. I typically shoot birds in a well wooded area. The foliage makes it difficult for me to keep ISOs under control with the f/5.6 aperture. It's all very well shooting in bright daylight but for the shooting I do, I'm yearning for f/4 or faster lenses ... f/8 just won't cut it even with the high ISO performance of the 5D3/6D

Owning a 600mm f/4 lens myself, I can tell you that you are often limited by too-thin DOF than you might expect. At 600mm, an f/4 aperture results in VERY THIN DOF. Quite often too thin. Unless you are photographing particularly large birds (which seems unlikely in a wooded area), even if you owned a 600mm f/4 lens you will find yourself somewhere between f/5.6 to f/8 often enough anyway. It does help having f/4 as an option, and when you really get down to the wire (near sunset in a wooded area) then you open up and deal with the DOF issues regardless.

But having an f/4 lens does not necessarily mean you are always shooting at f/4.

Ha ... I didn't think about that ... Thanks Jon!

I do my birding with the 100-400 right now and being limited to 400mm and f/5.6, I've not run into any serious DOF concerns - that will sure change with a supertele as you quite rightly point out above. The 100-400 isn't the sharpest of lenses and combined with super high ISOs, my pictures turn out too soft and lacking detail - I usually blame high ISOs for the lack of detail and noise and hence my cringing for a faster lens.

Aye, I always used the 100-400 at f/7.1 once I realized it was softish at f/5.6 and f/6.3. With a 7D, that really exacerbated issues with noise. Having the option of f/4 is certainly helpful for that. Keep in mind, you can get the 500/4 L II at a pretty significant discount to the 600mm f/4, and still have the option of using it at 700/5.6 and 1000/8 if you need to. It's a great middle-ground option when you can't afford the extra $2000+ for the 600mm.


I've used the 600 only a few times but that was for shooting shore birds in reasonable light so I could stop down happily without any concern over the ISO. 

I'd say the 600mm is the best lens on earth for shorebirds. At low perspectives (i.e. laying on the sand of a beach, lens on a ground-level pod of some kind) gets you the most exquisite background blur you'll ever see. The 500mm will do much the same, if you need the cost savings, but the 600mm can't be beat for shorebird work.

Jon, a large section of the buyers of the Tammy will end up using them on the APS-C cameras where diffraction sets in real early - sometimes as soon as f/6.3. If you were to stop down to f/11, how much do you think the images will suffer in sharpness?

This is the diffraction myth. Diffraction is diffraction, it is the same regardless of the sensor. The difference in pixel size simply means your imaging the lesser effects of diffraction sooner, but that does not make the effect worse. Diffraction is purely optical, so whether you are using a FF sensor, an APS-C sensor, or a small 4/3rds sensor with even tinier pixels, you should really NEVER worry about diffraction.

Read this:
http://jonrista.com/2013/03/24/the-diffraction-myth/

So, technically speaking, stopping down to f/11 is stopping down to f/11...the ultimate result on IQ in reach-limmited scenarios (same lens, different cameras, same subject distance) is roughly the same regardless of FF vs. APS-C (technically, APS-C would actually have the edge, barring blurring from other factors...i.e. the 7D has a stronger low pass filter than the 5D III, which mitigates some of the benefit of having smaller pixels, but not entirely.) Smaller pixels will always give you a cropping advantage, and the more you stop down, the returns offered by those smaller pixels simply diminish until they offer no benefit over larger pixels (but at no point would smaller pixel EVER be "worse" than larger pixels from the standpoint of diffraction...noise is another matter.)
That's a lot of very useful info Jon ... thanks for sharing.

Regardless if you like the look of the new G1x or not, you have to admit it's better looking that this eye sore!:

size of previous gen (nex 6 and g1x)
pricing is $800 with 16-50 3.5-5.6 lens
still packs apsc and faster af + faster burst.

OK. I agree with you. A6000 looks FAR more enticing for the same price, especially with in-built EVF and longer battery life.
Although I prefer Canon over any other camera manufacturer and having used the G1 X for a few months, I'd pick the A6000 over the the G1 X II any day.

Great Article. Thank you. I read it last week on Thursday and set  CF1 up with the multiple button zone af control. On Friday, I happened to be at a good place during a good time. I captured a sequence that included this shot thanks to your recommendations. I just received my 5D III through CLP last Tuesday.
That's a superbly timed shot ... AWESOME work FallsGuy ... but your online ID is not awesome, it sounds like "false guy"  ;D

You are blowing it out of proportions. There has been no personal attack against Dustin, only the obvious accountability for what he does and how.
I think you missed a few comments from few members. By the way I am not taking it personally, too bad if you feel that way. What accountability? if CR is allowing him to post his link, what is it to the rest of us ... his post is being made to sound like it is some kind of crime. If one is so concerned about "accountability for what he does and how", should it not be taken to the CR admin, instead of making Dustin look bad?

....

The backstage of a picture is interesting if it's a great picture. The picture in question, a broken tree without any context, is not. It could have been taken anywhere, anytime. The caption and the picture have no apparent connection. The picture could have any caption, the caption could relate to any picture.

The photo means nothing by itself and the elaborate text looks like a futile exercise meant to draw attention. Any random shutter actuation can be embellished with touching words, but it doesn't turn any of them into interesting images.
I absolutely agree with you that any random shutter can be embellished with touching words ... but one must consider the possibility that image can speak volumes to the photographer or for many who view that image. My point is not about people not liking the image, its perfectly fine for someone not to like (I know people who don't like Ansel Adams work). But what is not fine is, people casting aspirations on the photographer's integrity, honor and what not. Strangely, till now, no one provided constructive criticism on how that image or an alternative could have been presented to make his message come across more effectively. Comments, questioning Dustin's integrity have only generated ill will, instead of providing an opportunity to learn something. Personally, as mentioned earlier, that image speaks to me (and several others) because of the message associated with it ... it does not appeal to some, that is perfectly fine ... but lets not reduce a fellow CR member (whose work, most of us like and follow) with suggestions that his intentions may not be honorable. There are comments that suggest that Dustin did not receive any requests etc ... now how the hell does someone know what requests/comments Dustin has received? are they Psychics? or did they read every single request he has received from every single source, including for his 1400+ posts in CR? or did they hack into Dustin's inbox? What is not fine is when a few of the members behaving just like a cheap media house i.e. latch on to a popular guy and make him look like a dishonorable person ... that's just sick and a low life thing to do.
Peace.
Hi Rienz, I didn't question his person. I questioned his approach. If ones wants to promote one's work then be open about it. I've been doing business for about two decades and credibility and trust is everything.  If you want to sell something then you should say so. I think you agree.

Maybe we saw different things here but that shouldn't make us enemies.
Hi Arctic Photo, if you noticed I removed your name when I quoted Albi86 (above), coz I didn't want you to take it personally ... no hard feelings, we certainly not enemies ... we just happen to disagree ... who knows, if we meet in person we may get along famously. Don't take it personally. Have a nice day. Peace

these are same as above but at f/13 (1/80sec, ISO 125) and f/14 (1/80sec, ISO 200)

Thanks Rienzphotoz for sharing.

I'm going to take your advice on Sony e-mount 10-18mm. I'll keep you posted
Cool! ...let me know your feedback, when you get it ... I'll be getting it before 6th March (hopefully) ... if I get it before you, I'll give you my feedback.

@Rienz: I'm curious about the JPEG quality. You say these are strait out of camera JPEGs? When you move into the green backgrounds, the posterization and artifacting is really bad. Really quite bad, especially at the lower ISO settings. Any chance you could take a RAW and save it at maximum quality JPEG?
Hi Jon,
Unfortunately, I only shot them in JPG (as I had forgotten to change it back to RAW, after my recent timelapse session with the camera) ... also they are not straight out of the camera, I used LR 5.3 to add a bit of vibrance and saturation (with the brush tool), only to the flower ... as well as reduce the files sizes for posting here ... would the file size conversion cause the posterization and artifacting to the background? I'm not an accomplished photographer like you, so user error cannot be ruled out ... but I'll upload the full size JPGs (straight out of the camera) to dropbox or my Smugmug account and post the link, for your scrutiny ... but no harsh comments on user error please, I can't take it  ;D (just kidding, any comments on how I could improve the image, is always welcome).

643
Surely they mean mbit? 100mb/s would be 800mbit/s, which is pretty damn fast......  My own connection is only 60mbit/12mbit hehe.
I have a 1Gb/s network in my house; GB switches are quite cheap these days.

My guess is that the 100Mbps quote is a typo; it's more likely that their fiber-optic network is running at 10Gb/s.
+1

Does this mean there is definitely no dual-pixel AF in the GXII?
It looks like that ... otherwise they would have "leaked" that info first.

I agree, as little as positive comments also describing why it's good. I did not say it was bad.

So as I don't salute your work, then my opinion is worthless.
Artic Photo allow me to address 2 things you've raised in your above 2 posts:
1.
A positive comment without describing why it's good, still has a positive effect on the photographer, providing him/her with useful motivation/encouragement. But a negative comment without any constructive criticism other than it is bad (or it's no good or whatever), is totally worthless and useless for the photographer and the people reading it, as it provides no encouragement or useful information, other than spread ill will and hostility ... in such situations it is better to shut up and that does provide a powerful message ... trust me when I don't get any positive reaction to my photos, I get the message without anyone saying a word.
I am not saying that you said the photo is bad but I'm only trying to address your comment about positive comments should describe why it's good.

2. One does not have to salute anyone's work to provide constructive criticism, but it is absolutely worthless when the comments do not have an iota of constructive criticism about how the photographer can improve his/her image.

Maybe you don't mean it but your comments here are coming across as someone who does not like Dustin for whatever reason, because you have failed to provide any constructive criticism on how he can improve the image ... like I said, you probably don't meant to, but that's how it is coming across.
