Does anyone know if this will provide the same type of AF for say Canon lenses, via an adapter like that from Metabones, such as on the A7r II?

@vcsd

I'm not sure who's comment or what point you are responding to. However you must appreciate that if you are regularly cropping FF to APS-C size or less, which is common in bird photography, the FF camera has no high ISO advantage. In effect you are just using an APS-C sensor or less. If the pixel density on a FF camera when cropped to APS-C size, has the same pixel density as the APS-C sensor, the high ISO noise performance will be the same or worse than the APS-C sensor.

The high ISO advantage of FF is only there if the image is not cropped and the whole sensor image is being used.

An APS-C sensored camera like the 7D mkII, or even the 70D will still have an advantage over the 5DS, because they have a higher frame rate, and bigger buffers on the 7D mk II. This is why no sensor format is inherently better than others, and it is always a compromise of what is best for the job. It's always advantages and disadvantages, depending on what your purpose for the tool (camera) is.

Tom Caldwell: Once the bargain hunters get over the shock I think it will sell like crazy. Pity that Panasonic and Olympus cannot get their trick stabilisation systems to work with each other.

I can't see this lens being a big seller. It looks like an excellent lens, but the trouble is the price. For this price you could get a Pentax 300mm f4, a K-3 II body and a 100mm macro lens.

This is the essential problem with pricing this lens so high. Never before have there been so many affordable lenses for long lens photography. The Tamron 150-600mm and the Sigma lenses of this focal length changed everything. Now it was possible to get excellent image quality at an affordable price. Nikon responded by producing the very aggressively priced 200-500mm f5.6, which is nearly half the price of this 300mm f4.

Yes the m4/3 system has advantages when it comes to reach. But it is not really an alternative to 600mm FF lenses. A 400mm lens on Canon APS-C has more reach, and a 600mm f4 lens on a Canon 7D mkII has an eqv focal length of 960mm i.e. it would take a near 500mm f4 lens on m4/3 to replicate that reach and aperture. Even on m4/3 that would be a big expensive lens.

@vscd

In some situations you will be cropping all the time. A good example would be bird photography. My Canon 70D has more or less the same pixel density as a 5DS, and if you are cropping to APS-C or less all the time, there is no advantage to the 5DS. In fact my 70D has a higher frame rate than 5DS, and a 7D mkII twice the frame rate and a much bigger buffer.

It's only really with the latest higher pixel density FF cameras that you can do this. If you crop a Canon 5D mk3 to APS-C dimensions or less, it's like using an 8mp or lower resolution sensor.

Of course there are advantages to larger sensors, but all cameras are compromises. That's why in some scenarios a smaller sensor is better than a larger sensor, and vica versa. It's been the same throughout the history of photography, which is why simplistically seeing one format as better than others is mistaken. This Phase One will be a fabulous camera in some scenarios, and a handicap in other scenarios.

@ThePhilips

Yes, it's true that I have never partaken of FF Canons, although one would be useful as a wide converter for my Canon MP-E 65mm, as it starts of at 1:1, so is a bit tight on APS-C. But with ordinary infinity macro lenses 1:1 isn't enough to fill the frame with a fly.

In the old film days I did use 35mm film and even 6x6 Medium Format. There's nothing special about it though.

The FF bores who seem to think you can only take good photos with FF cameras remind my a lot of MF bores in the old film days, who would sniffily dismiss 35mm, as a miniature format, not up to serious photography. Personally I just see cameras as tools, and it's what is sufficient for the job. With macro and longer lens nature photography, I've always liked the longer reach of smaller formats. It's horses for courses. Bigger formats are fine, as long as you don't want plenty of reach, or to photograph very little things with infinity focusing lenses.

Just to clarify this. 35mm film i.e. 24mm x 36mm was actually called "miniature format", and smaller formats "sub-miniature format".

"Did they turn down guns to help hunting?"

I would recommend reading Boyce Richardson's "Strangers Devour the Land" for an understanding of the context within which hunter-gatherer people's borrowed technology. It was purely in the context of continuing their general lifestyle, and did not change it.

The lead shot poisoning issue is not really relevant. It is more a side effect from the way recreational shooters shoot i.e. concentrated in certain areas, and is not really relevant to using a gun in the context of hunting and gathering. It's to do with local concentrations of lead shot which waterfowl pick up.

Talking of Boyce Richardson. See this film he made in the 1970s, note how one of the Cree is resting the land on which his trap lines are on to let it recover. There is a better description in the book I referenced. I could give far more references, but space is short here. See how I use references and evidence for my points.

@Peacekeeper

Just to illustrate the absurdity of your claims and their fallacious nature.

Earlier you said to me.

"Judging by the prolific nature of your posts, you have plenty of time to explain anything you want."

Now let's look at the big long line your obsessive ranting posts, since I last posted a comment. It does highlight the hypocrisy and dishonesty of your jibes.

What you and Edgar_in_Indy have failed to grasp, is that I made a few simple points. The ideas and beliefs you are attributing to me are not actually contained in anything I've actually said. This is why you keep misrepresenting what I said. You are presuming I am arguing something, which I have provably never said - both of you. However, despite both provably misrepresenting what I said repeatedly, you both have failed to grasp that you were both making mistaken presumptions about what I said and why, and arguing against your own straw man arguments that both of you had set up yourself.

"Intellectually dishonest? Offensive? What are you talking about? Is the fact that I don't take you at your word as a "trained ecologist" offensive to you? "

I have never said anything on the basis of being a trained ecologist other than I had studied the biodiversity loss in depth.

You are the one engaged in bluster. Not once have you either used a reference, or referenced any evidence or fact. You have just made offensive personalized comments. You are unable to argue honestly, and quickly resort to the ad hominen logical fallacy, the fall back of those without the ability to argue the facts, and those who have lost the argument. Don't expect any more responses, because you are an empty vessel with no references, facts or evidence to back up your bluster.

So you can't quote anything I said to justify your false claims about what I said, and you have to resort to making it up. Your claims about what I said are just bare-faced lies because of your inability to engage in honest argument.

I just went through and checked. Not once have you quoted anything that supports your claims, and you are just being dishonest. I clearly challenged you to support your false and dishonest claims by quoting what I said to justify your claims, and you can't. As I said you wouldn't be able to quote anything to justify your claims, because I never said what you falsely claimed.

The straw man logical fallacy, which you have used repeatedly is a well known tactic of dishonest argument, used by those with an inability to argue properly.

"AGAIN, the one thing I agree with you about is the ecological impact"

Then what are you arguing about, I've never made any other points?

"It's the value judgments that I'm disagreeing with."

What value judgements, point to them?

"It's the ridiculous assertion that without Europeans, all other human societies would have continued to remain primitive hunter/gatherers"

Where have I ever made any such claim? You are just making this up, and arguing against straw man arguments that you've made up yourself.

No wonder you can't understand what I'm saying, when you are arguing against made up things I've never said.

You are just repeatedly using the straw man logical fallacy, in which you argue against points I never made, and which you just made up to make it easy to argue against. If I am wrong, you should be able to quote where I have said the things you claim. You won't be able to, because I never made any such points, you did.

@Edgar_in_Indy

It really isn't worth me taking this further. You are just making assertions and expressing opinions, which are unsupported by fact, or references. When I have pointed to the objective evidence which contradicts your unsupported assertions and opinion, you just ignore that. You just make more unsupported or erroneous opinion.

You are just trying to browbeat me into defeat, which really makes a joke of your laughable claim that I am bullying you, because I contradicted you with facts and evidence.

Unless you support your claims with evidence, or address the contrary evidence I have cited it is pointless carrying. As I say, this is not dialogue, it is an attempt to defeat me by making strident assertions.

"Are you kidding? You've made so many negative, subjective, opinion-based judgments about your culture that it will take me two posts to point them out and respond."

You clearly do not understand rational argument, and the difference between facts and opinions. My comments about impacts on biodiversity, are objective facts, not opinions. It is an objective fact, that the biodiversity of countries colonized by European origin cultures in the last 500 years or so rapidly declined after they arrived. This is an objective fact.

You may regard this as "negative" "opinions", but this is clearly because you don't understand what an opinion is. You have just made a series of unsupported assertions i.e. your opinions. You've never even tried to support your claims with evidence, or to contradict what I say with evidence. You need to understand the difference between objective fact and evidence, opinion, and unsupported assertions. Not once have you contradicted me on fact.

No it is you that is being selective. At no time have I made any general negative comments about Europeans. Unlike apparently you, I am a native European, born and bred here, so your claims are really not very credible.

My points were confined to the impacts of European culture i.e. not Europeans on the natural environment. They were not general comments about European culture, and my comments are solely based on Environmental Impacts. So advances in medicine etc, are simply not relevant to this context.

@PeaceKeeper

Your posts are offensive and deeply intellectually dishonest. There is massive academic discussion about what the population size of the Native American population was in pre-Columbian times. It is generally thought to be much higher than it was thought to be. It is impossible is such a small space to detail this with full references.

I will simply reference the Wikipedia article to demonstrate that I am not making this up, and so that can see that you are being intellectually dishonest, and offensively insulting. Note that I am providing evidence, and you are just making offensive personal attacks. This is called the ad hominen logical fallacy. It is an intellectually dishonest method, and what people resort to when they've lost the argument. It is used by those of low intellect. I stick to the evidence, and you get personally insulting. You don't know how to argue in a rational way.
