Slowest shot at 200mm + A7 ii


Recommended Posts

People with the new A7ii... Can you tell me the slowest exposure time you can use at 200mm, with the 70-200 f/4, without tripod to get a sharp shot and the difference without IBIS??? (everybody have different performance for stability/shake)

 

I want to know in the photography world the real effect of IBIS system!  

 

Thank you!

I don't have that lens, but in my experience with other OSS lenses the OSS is slightly better than the IBIS. The IBIS should only be a real gem for lenses without OSS. Luckily the lens you are referring to has OSS and should do fine IBIS or not.

 

EDIT: I will add that I toyed around with my friends Nikon 70-200mm 2.8 lens with an adapter, with IBIS set at 200mm and it definitely does make a difference if for nothing else, the image you are shooting being more steady when zoomed in like that allowing you to manually focus better. Turning IBIS off it was a nightmare, with it on I was able to get some decent shots, but sorry to say I really wasnt testing for how low of a shutter speed I could get good results, it was a bright day shooting a few birds that werent too far away, so my shutter speed was pretty high.

I use 1/60 quite often with no effort on my part, its fine, perhaps even slower with some technique. The OSS is amazing.

I just snapped this in my lounge room handheld, [ i squatted though, its more stable ] i had to lighten it a bit and a tad sharpen of course and its not a briliantly sharp foto but it shows you whats do able handheld with this combo. Its tungsten light source and not quite 200mm, the ibis really works though so i believe.

With the A7 ii and IBIS on?

With A7ii and OSS, which I think uses some of the IBIS (which itself cannot be directly turned on with this lens).

This shot is at 108mm, 1/6s with aperture f4. Its not perfectly sharp but given the parameters its a great outcome. The processed version is on my 500px profile.

 

I've added a crop of one section, it was pretty dark when the photo was taken so actually ... the focus might just be off given the poor light and large aperture.

    • Hmm that's pretty dreadful indeed... My 18-105 for sure is sharper than that. If I have time tomorrow I'll shoot an example with mine at 40mm f/8 side by side with the 16-55. Sold my kit lens when I bought the 18-105 so can't compare those anymore.
    • Thanks for the very useful information. The 16-55 tempts me, I can live with the absence of stabilisation, what holds me is the price tag. As always, there is not such a thing like a free lunch in life. The Sony gives performance at a reasonable size but with no stabilisation and higher price tag, the Zeiss is compact, stabilised and reasonably priced but lower performed, while the Tamron provides performance at very good price and stabilisation at the expense of bulkiness. 😀 All in all, I think I will give a try to the Tamron, once I have taken in my hands. Here are two cutouts taken close to the center of the picture. The sharper one is the kit zoom, the other is the 18-105 mm, at approximately the same lenght around 40 mm at /f 8. The difference is impressive and more impressive for me is that all the lenses in the shop had the same behaviour on two different cameras. At this point looks like a whole batch and not just a lens.

    • That's a pity and certainly doesn't match with my experience with the 18-105: mine is definately on par with the 16-50 kit lens (which on its own was as decent as I could expect from such a cheap lens). Sure, dont expect sharp corners especially wide open, but in the center my 18-105 left little to be desired across most of the zoom range. The 16-55 does beat it in every regard except zoom range though. The Tamron 17-70 trades blows with the 16-55 and might be the better choice in some cases. I went for the 16-55 because of the smaller size (I also found the 18-105 too bulky most of the time) and slightly wider FoV. My camera has a stabilized sensor so stabilized optics was no requirement for me. As you noted, I kept the 18-105 on my old A6000 for the occasional video project.
