jonny1976: pentax k1 + samyang 14 2,8 or samyang 24 1,4.....cost 2200/2500 dollar....

exposure till 1,30 minutes with astroracer without any startrail....
you can use low iso fo superb quality clean shot, mostly iso 100 to iso 400
you can use f 5,6 for optimal resolution, corner to corner sharpness, zero coma.....

nikon d810 plus sigma 14 1m8.....5000 dollar.....

you only can achieve subpar result especially shooting at 1,8.
to add a serious astroracer u need at least 500 800 dollar.

a guy specialized in astrophotography who use this combo is an ignorant not an expert.

astroracer clearly not keep the horizon steady. if composition add a fixed element you can use ps to stitch 2 files like any serious astrophotographer has done for ages.

is obtaining subpar results. for a professions who should always aim at best is not ana excuse.

using a pentax k1 in landscape astro add you

-tilting lcd
-key led light to illuminate key position in camera for changing setting
- adj of composition
- pixel shift

etc etc

WillWeaverRVA: Compared to the Really Right Stuff L-brackets (which aren't "universal"), this is a pretty good price. If it's just as durable, it might be a pretty nice alternative.

people simply don't know the brand...read some review..this is not any chinese producer...actually a british, the head ball they produce are amazing as far as tripod....
all isa producer right now are simply overpriced for their product....point...they still live in 1980 without any competition?
i bought many products from sunawayphoto or as is named, korean brand...top notch quality at 1/3 of rrs. but if you are to pay 3 times for same product up to u.

i doubt this is a slouch product...3 legged is one of the most quality tripod maker in the moment..simply rrs is way way overpriced. but if you want pay 170 bucks for something that cost 15 to make up to u.
it remember me when benro tripod were called slouch and cheap....my travel tripod from benro has 6 years still working like a charm despite costing 3 times less than gitzo

In reply to:

willmore: Computer engineer here who just designed a driver for such displays. The larger display is composed of small pannels--64x32 LEDs or so in size (they come in many sizes). Each pannel has a by 8 or by 16 multiplexing to them. That means a row of LEDs (RGB are all driven at the same time) is driven for some time unit and then the next row is driven and that cycle takes 8 or 16 of those periods to complete. Then the first row is again displayed. This is done at a very high frequency--those mentioned in the article aren't unreasonable.

Expect to see more problems like this in the future. LED lighting is only going to become more and more popular.

I would love to see some photos of displays like this taken with a camera lacking a low pass filter. The moire effect should be spectacular. The R, G, and B sub pixels are mechanically offset a small amount. If things line up wrong, all kinds of impressive distortions should be possible. :)

and we saw a football match shot in daylight...imagine at night?

Xentinus: banding ok...but aren't the photos a lil bit too noisy for 1600-2000 ISOs?

preview answer: " is not noise...is the details captured by the great master glens.

Triplet Perar: LEDs are now everywhere. There is no way LED lights will go out of the way to please the camera and sensor maker and their inability / handicap to design a proper sensor / E-shutter. But the apologetic tone of the article and replies are quite interesting.

you are spot on...were another brand oh my god...but sony spend million dollar in ads for a9...dpreview plagued all the web with tens of articles....in my opinion they only wrote this article to diminish what is clearly a top flaw for a camera aims at professional who will encounter this kind of light every day....call it a niche speaks volume about the commitment of this website to some brands.
i remember the pixel shift article about pentax and their " totally useless " while i use pixel shift everyday and is completely useful in many field of photography...now they say is only a niche...this camera is full of flaws....and cost 4000....

In reply to:

Yossarian1: Hmmm.. How many times did you say 2% of the photos shot (count it - three times in the article)... Sounds like a bit of defensive spin and not very scientific.

If this is the cause (and it is quite plausible that it is), then suggesting that it will only affect 2% of the photos shot (as your last paragraph implies) is misleading. This will be dependent on the extent to which you are shooting in this particular light - so 2% may actually be 10% or 20%... or even higher.

Given that LED boards are becoming more prominent at sports events (because of their ability to change messages and catch the eye of the TV viewer), it is something to note and consider.

also it can affect THE SHOT....i mean one photographer can discover the best shot one who can break the bank of his career affected from severe banding...sure is only 2% but the shot of is life is ruined....unfortunately pro sport shooter after this will have the last answer to their doubt of buying this camera.
for rich amateur it still can be a nice camera especially cause kids won't play around led advertisement probably...but any pro cannot allow themselves to lose even 2% of shots.

In reply to:

DPPMetro: This is absolutely NOTHING to discuss. 2% in Fro's usage is nothing. True, it can be THE shot that gets someone's career going, but the fact of the matter is that in any digital camera, we all face anomolies of some sort, at some time. We are now at a point where we are nitpicking about every little thing.

Anyone who hasn't had some sort of technical anomoly in digital photography with "conventional" gear already simply isn't shooting enough. Whether it be blowing highlights, dealing with red LEDs on stages, warm lighting, tungsten, intense point light sources, extremely fast-moving objects, auto focus, moire, and on and on. Hell, push many cameras in post and see some sort of curved-field banding/grid patterning show up.

Bottom line: we're all dealing with technical phenomena and anomolies already as part of digital photography.

so in practice you are telling all those wanna be pro sport shooter to use the mechanical slow 5 fps and slow as hell mechanical with slow refresh every time there is light in stadium, practically any night and evening event?
this camera the more people used the more show weakness.
maybe in 10 years,

CALLAGHAN92: For me the LEICA SL is far much better with awesome lenses and much more solid.

well i tried a9 in shop..i'm pretty sure if i throw it from one meter it will go pieces..the 1dx k1 d5 645d won't scratch some borders.

jonny1976: Conclusion:
The AF worked fine - better or worse than my Nikon? Not better, but it was acceptable for a first time use - more games and photographing other kind of sports would be needed to draw the final conclusion.
Is the A9 a game changer?
No - but it is probably the beginning of a game changer. Within 5 years a pro-sportsshooter could very well be working with mirrorless cameras.
Would I change my Nikon for this camera?
No!
Three reasons to why not:
- Not enough pro-lenses
- No IPTC in the camera ( this could be solved with a firmware-update)
- Not enough accessories

If Sony come up with the pro-lenses they will be in the same league as Nikon and Canon.

https://www.ronbog.com/blog-ronbog

pretty much my feeling...i doubt many pro will buy this system now...maybe in 5 years...so far 4500 ar a lot for non pros..for me the camera in a year will los a lot of the price and it could be a good buy. so far no.

i tried the a
9 in shop and even with the 24-70 f4 the camera was completely unbalanced....like i hold practically the combo from the lens not camera. i cannot imagine a 70-200...and all the zoom i saw in the presentation are probably bigger or the same as any normal dslr brand. so if u shoot small prime u have a combo well balanced...with zoom this camera look ridiculous.

i always hate sony as brand abut this is the first camera i would buy. but i tried in shop and the body is appalling but i shoot k1 that in ergonomic and building is also a milestone.
but really those square corner, small pattern , clumsy button, everything packed, difficult to put hand around the camera.
probably the same technology could have been put on the a99...if they put this technology in a99 they could have really earned sport photographer.
with the format of sony alpha 7 they won't have any sports photographer.

In reply to:

surlezi: People here talk about camera, and comparison of camera. Now with this one, it's all down to electronics. The sensor is 90% of this camera, and most of what's amazing in it is because of its electronics.

The body itself is nothing. I'm not sure why Sony won't make a flawless body. Minolta (bought by Sony) already made better bodies 13 years ago with Dynax Maxxum 7D, with dials and ergonomics way better than what they have on A7/A9. I guess it's a way for to leave room for improvment, because with such sensors, customers would'nt be upgrading in a long while.

well tried the sony a9 ion shop...af is amazing no doubts, and am a sony critics, but ergonomics is terrible. i have big hand...without grip is all packed, i have very minimum space for grip camera with both hands...controls also not the best ergo..coming from pentaxk1 and pentax superb ergonomics i was not impressed for a 4500 camera.
personally they could have produced a body more oriented towards this class of camera, instead of simply reusing the a7 body to cut cost still asking more money.
some more inches here and there would have really made this camera perfect more sealed possibility and a real contender. i doubt one used to d5 could love a camera like this.

"even with my small hands it’s a challenge getting a good grip on the camera-body because you don’t know where to put your your little finger.
this is exactly my feeling. sony always fails somewhere big in any camera. this time body.

DPPMetro: The tradeoffs seem very reasonable for the ones who prioritize that speed and focusing. Basically, this is not a toy for hobbyists, though no doubt a large number of spec-sheet photographers on DPR will buy it so they can take challenging flower photos with it and then will complain.

i tried it in a shop and apart the af and speed the res look like a toy starting from the limited grip and very small body whit big lens. compared to a 1dx and d5 looks like a toys.
sony will sell this maybe in some years a t 2000 euro.
5300 euro in europe...ahahaha

HowaboutRAW: There's much to like about the A99II and the A9.

But the A99II still needs better lenses, more of them.

And given that the A9 is supposed to compete with the likes of the Nikon D5 and Canon 1DS Mark II, the A9 body is too small.

A bigger body would allow for better heat dispersion, so the A9 could actually be shot at ISO 50k.

(As it is, the A9 stops being useful at about ISO 30K, mechanical shutter--raw, which is about Nikon Df territory, or Leica SL. It's big colour blotches that are the issue, not conventional noise/grain.)

It's an error on the part of Sony that the A9 can't remain mounted to a tripod head and still allow the battery to be swapped. The D5, 1DX II and the Fuji GFX-50S don't have this basic flaw.

The A9's mechanical shutter frame rate is too low for a "pro" body.

pro camera are built to last everything or most of them...the a9 won't last like a d5 or a 1dx bit not even a d800 or k1.
the button are all packed and so flimsy is impossible for those with big hand to use it without taking the eyes off the viewfinder..

in addiction it has evf, still look like watching a tv instead a ovf..i prefer the second

nobody abuse it...but believe me when you do serious photojournalism and u run everywhere in th middle of people in small spaces, your camera hanging from our side is pretty easy to smash the body against somebody or something, and this camera don't give me the appearance that it can manage this very easy.

i agree. i am a guy who take a camera and in a second i can manage all dial and control..the ergonomics is not very good, even button and lever look flimsy...coming from a k1 for example is like night and day, building ergonomic of k1 are 4 notches ahed this camera.
sure it has what seems a very good af, and frame rate, so many pro could add this as second body. but for 5300 euro is a joke really. at 3000 probably would have been a good choice for many semi pro or amateur with big pocket, at 5300 any pro doing sport will choose night and day canikon.

i agree with dppmetro. i use pentax gear, two years ago i had my 645d on a sling back. i haven't close it:( so walk i in the street and the 645d fall down from1,8 meter, I'm 1,90 mt. well apart the outer ring of a metal lens, god it was old metal lucky, who bend, the camera had nothing zero damages...i'm sure this sony would have gone to pieces.
