A Quick Note on the Sony A7 III Sensitivity

Shooting with extremely long lenses like the 150-600mm Sigma requires higher shutter speed and to compensate for this, higher ISO levels are required.  This gave me a chance of seeing the result of using 6,400 and 10,000 (and higher) ISO sensitivities.  And I will tell you I am extremely impressed.  I have a hummingbird picture at 6,400 that is perfectly fine.  I’m sure if I subjected it to very close scrutiny and blew it up to 200% I’d find issues.  And that would be crazy.  My point is this camera has really excellent 6,400 ISO results.  The next test is to take some photos at that sensitivity in a low light indoor environment.  If it passes that test then this is the camera I was looking for when I was looking for a successor for the Sony A-850 in 2011.  The A850 was a great camera.  It had a best in class 24 megapixel sensor and  shot beautiful 100 ISO photos.  Even 200, 400 and even kinda sorta 800 ISO photos were also very good.  but try to take photos in a restaurant at 100 or even 800 ISO.  You’ll have motion blur and worse.  So I used to take 3,200 and 6,400 ISO shots that looked like a Monet painting with color noise swirling around everything.  I tried to convince myself that I liked the result but it was pathetic.  Now here I am a mere seven years later and all’s right with the world.  Well, that’s assuming the indoor tests go as hoped.  That also assumes the low light autofocus is as advertised.  Stay tuned.  Results will follow soon.

I mentioned in an earlier post that I watched a video that the TheCameraStore guys did that tested Metabones and Sigma (MC-11) adapters for Canon mount lenses onto Sony e-mount cameras.  In the video they said that on Canon brand lenses the Metabones adapter was better than the MC-11 and had pretty good autofocus.  But they also said that on Sigma brand lenses (of Art, Sport and Contemporary series) in Canon mount the autofocus was virtually identical to native Sony lens autofocus.  Now that really got me thinking.  Sony lacks really long glass  and a 200mm macro lens.  Sigma has a 150-600 that is pretty sharp and a 180mm f\2.8 macro that is also reputed to be good.  The 150-600 is part of the Sports series and therefore one of the lenses that the MC-11 is tuned for.  The MC-11 isn’t programmed for the 180mm macro so that was a question mark.  I decided to rent them and the MC-11 and test them out.

Between work responsibilities and bad weather I’ve only had a chance to do a little testing but I have confirmed that the MC-11 does give the 150-600 truly excellent autofocus very similar to a native lens on the A7 III.  And the 180 macro does not have that native autofocus programming with the MC-11.  The display registers an array of rough squares for the focus points.  This looks like the older autofocus from the version II A7 cameras.  So I can confirm the accuracy of the description of the MC-11’s ability on the Sports series.  The 180mm macro autofocus is definitely at a lesser level than with the specified series lenses.

But I still am interested in the 180 macro as the best choice for the A7 III camera.  So I’ve been trying it out for some bird photos including hummingbirds.  So far I like the results.  Next I’ll try some butterflies if they show up in the next week or so.

06MAY2018 – OCF Update

This week I’ll finish up reading Larry Correia’s “Monster Hunter Seige” and post a review.  The hard cover version came out back in July but I buy the paperback for convenience and that version just got issued.  The site has been a little slow because I’m putting together a sort of “best of” post on my southwest landscape trip for a link that Captain Capitalism is providing me and it’s a time-consuming endeavor.  It’s like eleven hundred files and I’m still learning how to use Capture One.  So bear with me.  That post should be pretty interesting for the photo enthusiasts.  As I mentioned earlier I’ll get those rental lenses on Friday the 11th and that will spawn some interesting posts on the viability of using Sigma lenses with Canon mount on the Sony A7 cameras.  That may be interesting to Canon shooters with Sigma glass who have been interested in switching to Sony and anyone who is still constrained by Sony’s telephoto and macro lens choices.

The other thing I am interested in writing about is the direction of right wing movement.  I am trying to formulate my own particular spin on what makes sense going forward.  There is a lot of confusion and undirected anger that doesn’t seem to be producing much in the way of results.  And there seems to be a certain amount of opportunism and charlatanism that makes it difficult to know what is solid and worthwhile.  Sometimes it seems that several people have each latched onto a different piece of the puzzle needed to reform the current situation but like the blind men and the elephant they only “see” a small part of the reality and are missing the big picture.  And because of that, they diagnose that small part of the problem and their solution doesn’t address the broader situation.  And some of the “wise men” are too extreme.  They would throw out the baby with the bath water.  The more I think about solutions for the social disintegration the more I think that restoring the common-sense institutions we used to have is the solution.  Stopping unlimited immigration is neither impossible nor radical.  Restoring respect for the traditions and institutions of our forefathers is important and relatively straight forward.  And replacing social justice and reverse discrimination with actual justice is so rational that it shouldn’t even require explanation.  I think some of the emphasis on race reality is a response to the absurdity that occurs when racial and sexual protectionism and intersectionality tactics are used to attack the American white middle and working classes.  If you eliminate these irritants then the rules of American society should be competent to allow different types of people to function relatively harmoniously.  Anyway, that is what I’m starting to think.  I’m definitely interested in other opinions.  And I read around to hear what other people are coming up with.  For instance I’m going to read Gregory Cochran’s “The 10,000 Year Explosion: How Civilization Accelerated Human Evolution” and David Reich’s “Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past” to see if there’s anything in biology that rules out my optimism for a functional multi-ethnic America.

And finally, I’d love to get more feedback from the readers.  Even if it’s negative.  It’s useful to know what you like and what you don’t.  Or even to just say hi.  It’s definitely appreciated and part of why I made this site.  I am interested in hearing other points of view.  And if you find something interesting on-line pass along the link.

My Undiscovered Country in Sony Shooting

Where I work there is a formal, company sponsored photo club. They have a budget and they have funded events where they go together to an arboretum or a museum and talk about equipment and techniques.  They have a charter and code of conduct.  They include everyone and value everyone’s contribution.  They give out tee shirts at the end of the year.

I don’t belong to that club.  Life’s too short.  I get together with about four or five guys who work there at lunch time.  We’ll go to a park or walk down the street or try to find a building that’s interesting.    We also occasionally take over a conference room during the lunch hour and throw our personal off hours photo results up on the big screen that usually features power point presentations of diversity training or unconscious bias hectoring or whatever else Big Brother needs us to absorb that week.

And some of these guys are pretty good.  It’s spring, and from a photographic point of view there’s finally a reason to live.  Normally we would already have gone out on a lunch time jaunt to see the dogwoods and weeping cherry trees in bloom.  But this year several of these guys have been shanghaied into a shift change to work on a big engineering project.  All of that ends on Friday, May 11th. To celebrate my brethren’s release from bondage I’ve scheduled an outing for the next Wednesday to a park that we hope will feature birds and bees and flowers and trees.  Maybe even a few butterflies.  And to make it interesting for me I’ve reserved a few lenses from a rental company for two weeks starting May 11th.  I’ve rented the Sigma MC-11  EF to E mount adapter and the Sigma EF mount version of their 150 – 600 Sports zoom and their 180mm f\2.8 macro lens.  I watched a video that the The Camera Store guys made testing out the MC-11 with Sigma EF mount lenses on one of the modern (A9 or third generation A7  cameras) Sony full-frames.  They rated the autofocus performance almost exactly as good as Sony native glass.  Now there is a catch.  It’s only warranted to be that good with certain lenses.  The Art and Sports series are covered.  So the 150-600 is in that group.  The 180 macro is not.  I spoke to the rental company and they didn’t know one way or the other.  But they did say I should try it.  Of course I’m the one paying for the privilege but I figured it was worth a shot.  So in about two weeks I’ll have something to say about the A7 III, the MC-11 and birds in flight.  Sony has never allowed me to even try such a photographic feat but here we are, a brave new world.  And with any any luck the 180 macro will prove to be good for butterfly shots.  Currently my only long macro is the Minolta 200mm f\4.  But it’s screw drive and if I want autofocus I have to use LA-EA4 with its “translucent mirror.”  For me that’s something of a compromise.  If the 180mm and the MC-11 combination turns out to have pretty good autofocus I will most probably buy those two items and retire the 200 mm to static macro and short telephoto opportunities with the LA-EA3.

So this is just me salivating in anticipation of the opportunity coming up in a couple of weeks.  To say that I’m impatient would be the greatest example of understatement since Jack Swigert said “Houston we have a problem.”  So stay tuned.  If you’re a Sony shooter these tests will give you information on options that aren’t currently available in the native Sony e-mount ecosystem.  And, even if they were, the cost would be prohibitive even to someone with my gear obsessed psyche.

Sony A7 III – A Camera Review – Part 1

Helebore flower

 

I’ve had the camera for about a week.  I went out today to get some first impressions.  The first thing I notice is the difference between the A7S and the A7 III is the autofocus.  It’s night and day.  I used center point AF.  Whatever I pointed at was instantaneously in perfect focus.  No hunting, no off-focus just dead on crystal clear.  Now granted, this is in bright day light.  But if you’ve ever shot the A7S you know that even under these conditions the photo had a more than even chance of being at least slightly out of focus.  I took it as standard operating procedure that magnified manual focus was absolutely necessary for guaranteed perfect focus.  Of course, think of what that means for a moving subject.  It meant you couldn’t get the shot.  So, the A7 III is a revelation.

The next thing I noticed was how convenient it was to have the viewfinder stay in magnified mode after autofocusing a view.  Now I can make sure that if the scene is ultra-crowded with competing focus targets that the right one was selected.  Or if something has moved I can re-focus without having to re-engage the magnify steps.  This is especially nice for macro work or distant objects.

The next thing was an item I noticed while inspecting the images on the computer.  The 24-mp files are amazingly croppable.  This contrasts with the 12-mp A7S files.  I’ve attached an extreme crop of a flower.  The focus was excellent and the crop has tons of detail.

And finally, looking at the images on the computer they seem to have a very nice look to them.  Of course, the A7S produced nice files too but these look very rich.

These are just my first thoughts.  Later on I’ll review the various functions on the camera and how they work or don’t work for my shooting needs.  But right now I have to say that except for extreme low light or star photography I can’t imagine using the A7S instead of the A7 III.

Sony A7 III – Oddball Test

I was taking a bunch of test shots with the A7 III today.  As I mentioned earlier the longest Sony lens I have with native e-mount is the 55mm f\1.8.  I saw an opportunity to test out the autofocus at a long distance with a moving subject.  Because I took this at about 150 feet away I cropped this thing to a ridiculous extent and it shows but also notice that the fox is in focus.  Pardon the poor quality of this jpeg (figuring out the new Capture 1 for the A7 III)  but this tells me two things.

  1.  The autofocus is very, very good.
  2. I’ve got to get some longer native e-mount lenses.

Sony A7III – The Eagle Has Landed

Camera Girl signed for the camera today.  Tonight, I’ll set it up and see what I have to do to get a Capture 1 upgrade for that camera.  I think I’ll take some pictures of my grandson playing soccer tomorrow morning, to test out the autofocus.  If I can’t get the Capture 1 update I’ll have to go with jpegs.  Hopefully by the end of the weekend I’ll know if this camera is the end of a long road of Sony waiting.

Sony’s First Real E-Mount Sports Lens is On Its Way

Sonyalpharumors.com has a photo of this new pro sports lens discovered out in the wild (https://www.sonyalpharumors.com/sony-400mm-f-2-8-versus-canon-lens/) .  At over $10,000 each probably the only buyers will be pro sports shooters (and a few old rich guys, of course).  Looks like Sony is serious about the sports market.  I’m guessing at some point if the market materializes for them they’ll put out a 600mm f/4.  Of course, they might get some competition from sigma.  They’ve got some telephotos and unlike with wide angles the long lenses would easily adapt onto the e-mount with no need to change the lens formula.  Should be an interesting situation for the Canon and Nikon pros.  I’m sure being able to use the no-blackout, 20 frames per second A9 for football or soccer would be a very tempting choice for the guys who do that for a living.  Good work Sony.  Now let them come out with the A7 III.  I hope it has the same good autofocus as the A9.
