100-300 vs. 50-200+1.4TC: surprised!


Testing my new equipment here at the long end.

I must confess that I bought the 100-300 without any hope. Consumer slow lens, what to expect.... However, I am deeply and pleasantly surprised by this little lens.

My previous long lens was the 50-200 SWD + 1.4 TC + 2.0 TC. The 2.0 is soft, but the extra magnification compensates for that. The problem with that 2.0TC is that it is virtually impossible to hand hold, so I only use it with a tripod.

So my main wildlife gear was the 50-200 + 1.4 TC, and I decided to test it against the 100-300, both in the EM1. I took 10 pictures of each setting in RAW, identical shooting parameters, choose the sharpest, processed without any treatment with RawTherapee except for curves, everything hand held.

Well, the 100-300 (wide open at 5.6) at 280mm won easily against the 50-200 + 1.4 TC (stopped down also at 5.6!!). I'm still surprised about this. Maybe I shouldn't, since I loved the FZ50 lens.


Oly 50-200 + 1.4TC at F5.6 1/400s ISO200 and 283mm. Around 20 meters, beautiful day

100-300 at F5.6 1/400s ISO200 and 280mm. Around 20 meters, beautiful day.

ISO400, 1/200s F5.6 280mm, around 3 meters

The difference is quite big, even downscaling.

So I was waiting for the M.Zuiko 300mm F4. Now I'm not sure anymore if this would make a big difference... Of course, I would have to see a comparative output. Now, the only negative point about the 100-300 is the lack of weather seals.

The good news for the 50-200 is that I can handhold it with the 2.0TC, thanks to the IBIS.

Another surprise with the EM1 was the stabilization. I took several keepers at 300mm and 1/30s! Amazing. Look:

1/30s F5.6, ISO 2500, Flash off, EM1+100-300 at 300mm

But the EM1 IQ at ISO200 is not good, too grainy. That's my only complain (for now).
