Few photo with the 7S

fzrTom · Jan 12, 2016

Nothing really exiting but few photo done with the 7S + LA-EA4 and 50mm F1.4 and Tam 70-300 SP USD

The only purpose of this topic is to show some photo to people who are interested by the 7S.

Dont believe the ISO in the exif because at the begining I had often underexposed by 1 or 1.5 stop so if you want to know the real ISO, it's 2 times the value written in the EXIF.

Birds are small and always moving.

All photo taken last month and this month so with low light.

ps : sorry but I didnt post the most interesting photos (child, indoor family, ice skating ...).

Grey croned crane : Very big crop, the real ISO is ISO 4000-5000

Grey crowned crane : big crop with the same settings (real ISO = 4000 - 5000)

Horses playing (real ISO is 4000)

A nice Kiss

Demoiselle crane

The bigest bird I have ever seen (...)

Goldcrest : the smallest bird in Europe (5g) moving fastly, real ISO is ISO 4000

Goldcrest : same setting (real ISO is ISO 4000) always moving really hard to shoot

A jay

Hard to eat that !

A straling : hard to shoot because in the shadows

A magpie eating

A ring necked parakeet eating in the wind

Ready to flight

A tit flying in a Chinese apple tree (luky shoot)

A red squirrel in its winter coat (real ISO is ISO 5000 to 6400)

A red squirrel eating (reall ISO is 5000 to 6400)

Hey Franck,

Love the pics . .all of them. Was just wondering if these were all shot in APS-C mode, or you did FF and just cropped off the vignettes? Or don't tell me this combo of adapter & lens (the 300mm one) didn't cause vignettes !

Hello,

Thanks a lot !

I only shot FF (no APS-C mode) and RAW

To answer to your question :

A lot of photo have been croped in PP but not sure that they are all croped : fe the parakeet photo is not croped I think.
The 70-300 SP USD is F5.6 at 300mm so it has not a lot of vigneting
and I usually shot at F6.3 F7.1 or F8 so it reduce the effect of vigneting
I PP my photo with DxO and the SW correct the vigenting effects
The big pixels of the 7S avoid sensor vigneting (their are 2 sources of vigneting : lens and camera sensor, sensors with small pixels produce a lot of vigneting exepted if they have the BSI technology)

Still learning too. I have this camera since only 2 monthes. I'll try the auto ISO too next time. I always fear "autothings" because they often fail (depending for exemple on where it measures the light) but let see how the auto ISO works next time. Maybe it gives better result than fixing an ISO and correcting the light with PP ? I'm used to fix an ISO and watch the histogram to be sure that all is OK, it was the best way to take photo with my A58, but maybe with the 7S it is no more the case ? With the A58, I have had problem with auto ISO or A mode for example with small objects : if I aim to a shadows then usually the camera use a to big ISO setting.

It is too easy to have nice photo with this camera. ISO is no more a problem so you can do what you want with Aperture and Shutter Speed, no compromise and photo are always sharp with a great IQ. The only thing I miss is an LA-EA6 with the AF module of the A77-II : PLEASE SONY !

ps : Did you try DxO 10 and PRIME denoising feature ? It can produce impressive result at high ISO. If not, it is free for 30 days.

Franck,

The auto ISO works great for indoor dinners and parties, with everyone else shooting off with their flashes, I can get away with the 28mm f/2 or the Batis 85mm easily. I too used to do what you do by fixing the ISO - I guess this is the traditional school of thought. Good thing is, even with auto ISO, the +/- controls still work and the camera will adjust the ISO behind the scene With "regular" cameras we could never afford to do this, but now we can !!

So far I'm using the 7S mostly for portraits and have mostly given up on wildlife and birding, cos I think the Metabones IV AF still isn't fast enough on the camera. Waiting for them to come out with a 300 or 400mm zoom

AutoIso : I just tried a bit auto ISO and it seems to work perfectly. Let see next time maybe tomorrow with small subjects like tits.

Portrait/Still : I mostly use my A7S for still photo too. Portrait, indoor family events, spectacle ... A lot of people fear to use the 7S for still, but this is an error. Last week I was with some friends (babies birthday so indoor shooting) and they were surprised to see how bright, colorfull, sharp, ... were my photo. The ISO used was beween 4000 and 10000 and the shutter speed 1/250s to cach moving childs ...

Birds & E mount : even if Sony release a 400mm E mount lens I'll not buy it because the contrast AF of the 7S will ever be slower than the Phase AF of the LA-EA4 and then this lens would be very expensive (the Tamron 70-300 SP USD cost 300E !!!)

Here few other photo : some are not croped, at 300mm F8 there is no vigneting.

This photo is not croped

It should work fine with almost any subject. Of course if its dark, ISO shoots up and noise will still appear sooner or later, but at least you can get the shot.

It is most definitely an error, because with such large pixels, we get tremendous detail.

And the focusing could still keep track of the moving child?

I think this would mean that with the A7S or even the 7S2, we will never be able to shoot birds in flight due to the slower contrast detection. I may have to get an A77 II for that instead, unless I give up BIF

I like this a lot

Very clean photo with no sign of vignetting at all .. I think my problem so far is shooting everything wide open, or maybe stopping down 1 stop only.

Again a very clean & great shot

No, LA-EA4 has only 15 AF point located in the center of the field. So Tracking doesnt work. I only use the center AF point.

I think that the only solution for BIF would be a LA-EA6 with th AF of the A77-II.

I shoot indoor with a 50mm F1.4 but usually I stop it down to F4 (or at least F2.8) because I need more DOF than with F2. So I have almost no vigneting. Then if there is some vigneting DxO correct it (it has a data base with every lens/camera). The F1.4 lens is very usefull for the AF because the AF sensor receive a lot of light.

I did a try to auto ISO today and it is working really well.

The only issue is that often I forget to watch which ISO is selected by the camera and sometime I should have change the shutter speed to avoid too high ISO. FE my setting was for little bird moving fast so 1/1600s to 1/2000s but suddenly I saw a madarin duck in a really dark area. I should have use a shutter speed of 1/300s as he was not really moving. As I was not watching the ISO, I didnt saw it and I took photo at 6400 ISO (my ISO max in Auto ISO) but then I have had to add 2 stop more because it was too dark, that means that the real ISO is 25600 ... and I should have use ISO 5000.

But anyway I'll now use auto ISO and I'll have to be more attentive.

Here the photo I did today in Auto ISO : http://www.dpreview.com/forums/post/57139235

And here the Madarin :

+2 stop correction in PP : the real ISO is 25600 but not 6400.

The photo without correction at 6400 ISO : too dark

Franck,

Even at 25600, there's hardly any visible noise, so I'd say auto ISO works good for you too. Well done !

Yep because I used the PRIME denoising feature of DxO but anyway this is for me still amazing. 25600 ISO is a crazy high ISO, but DR, colors, noise ... all remain OK.

So thanks again for the tips, it is very usefull !

Thanks a lot !

I have posted new photos this week including this one that I like a lot.

The photo has been done at 6400 ISO and as you can see the IQ is still very good.
