Best Wildlife Photography Lens for MFT Comparison 

Good to hear the 300/4.0 is sharper. I can see myself saving up for one, bit the 150-400 is just too rich for my blood.

Thanks for a good honest reviewI wish I’d listen to you I purchased the 150 to. 400 end is woeful at best so soft. Luckily I have the 300 mm F4 and the 40-150mm f2.8 . Most of the Olympus ambassadors shoot back light shots The details are blown to bits. If this is the type of photography you enjoy no need for lens costing £6500. For me it is a case of a fool and his money are easily parted in my defence I was just hoping it would be the same 400mm as 300mm F4 is at 300 mil. It’s well short of that.

Thanks so much for sharing another wonderful video like always Jeremy 👍👌

Great review! Sharpness is MOST important to me. The 300 with a X1.5 or x2 would make up the difference in range and then some. I already own the 40-150mm 2.8, So I've got the lower zoom range covered. The idea and reason I moved into the of MFT is the many benefits it gives other than low light. SMALLER, lighter, an cost efficient is the name of the game, and the 150-400 kills that for me. But for some egos, I guess it looks the part. With the money you would save... you could buy a Panasonic G9II and another lens.

Great video, although I really enjoy watching all your videos. I have both lenses but ended up using the 150-400mm most of the time. it performed great a month ago when I was in Costa Rica, the weather sealing for body and lens was a life saver in those conditions! Cheers from Canada

Hi Jeremy, a short side note. M43 is always compared to FF, but for glass quality of lenses e.g. f4.0 stays in physics f4.0 of glass quality. it does not depend at M43 or FF. the difference is the dept of field only and the look and feel of background and this is influenced by the sensor size. M43 appr. double DOP of a FF. So, a FF f8.0 lense is not the quality of a M43 f4.0 in perspective of overall lense and glass performance.

Yes you have a little more reach with the zoom, but what is the first tool we use in post process? - The crop tool. For birds, it is the 300mm every time. The zoom can be hand-held, but it is a large lens, and defeats the objective of M4/3rds, when you root yourself down with a tripod.

Nice review. I returned the 150-400 after extensive indoor/backyard testing and one morning on my kayak. I am sticking with my Oly 300 f4. The 300 f4 is equal to the sharpest lenses I have ever used like the Nikon 300 f2.8 VR. The 150-400 gives amazing flexibility and although it is not nearly as sharp as either the Oly 40-150 (at 150) or the 300 f4 at 300, it does not need to be in this range. Why? If you are using the 150-300 end of the lens, you are frame filling your composition. In real world settings I could not see the difference. But who buys the 150-400 primarily for the 150-300 end of the range? You enjoy the wider end for flexibility, but you spend $8000 (with tax) for the 400 mm end plus flexibility Here is where my problems began. I visited a friend and used his 150-400 and when I got home I hated all the images. I noticed I accidentally had the 1.25 TC on in all images. I chalked up the poor results up to the TC effect. So I ordered my own 150-400. Whoa, the 400mm end without the TC is soft. Cropping 300 f4 images to the same size were dramatically better. I really hate having to over sharpen images and seeing the resulting visible artifacts on my monitor as occurred with the 150-400 at 400.

Great comparison! That 300mm looks oh so nice. Have you made a video comparing the PL 200mm 2.8 (w/1.4 TC) to the Oly 300mm? I would love to see you put those two gems head to head. As always, love your content!

There are so many 300mm lenses on the used market, it's easy to pick one up used at a steep discount with a limited warranty from a retailer selling used gear. I bought mine for USD2,000. I have not seen a single 150-400mm on the used market yet - and given the wait list for new ones, I doubt you could save much buying used. I'd be interested to hear about your opinion using the 300mm with either 1.4x or 2x teleconverter.

I've had the 300 f4 pro and now the 150-400 and the 150-400 is a little sharper or the same in my comparison, Go watch Chasing Luminance video when they compare it and see, Both great lenses but my pick is the 150-400.

I'm neither a technophobe or a Luddite but when using cameras for wildlife, I much prefer the ease of use of DSLRs. I have a D5 with a Sigma 60-600mm attached but I also have a Lumix G9 with the 10-300mm lens. I find the latter too fiddly whereas the D5 and lens, although being more unwieldy and MAHOOSIVE, such much easier to use. Everything directly at your finger tips.
