Long lens for my GX8 -- or just crop from 20MP?

    Hi guys, I need an opinion about a long lens choice for my GX8:

    I started shooting the GX8 and 12-35mm lens about a month ago, absolutely loving it. I was planning to add a long lens to the kit sooner or later, because I really like the compressed perspective of landscape/cityscape from a telephoto lens. I was tossed between the 45-150mm or 14-140mm lens. The 14-140 came up to mind as they both have the same weight, and I see no reason to have more lens swap with the 45-150mm lens.

    But then I was also thinking: "hey why not get a long fast prime, let's say 42.5 or 45mm lens, and use the 20MP from the GX8, and crop as needed?"

    The only cons of the 14-140mm that I can think of, is that there will be days when I struggle to choose between 12-35 or 14-140 (not going to carry both!).

    I hope I made sense. How would you approach a situation like this? Any thoughtful comments would be appreciated, thanks!

    To get the same resolution from a 42.5 cropped to the field of view of a 140, the resolution of the 42.5 would have to be 3x that of the 140: it isn't.

    Personally I wouldn't be thinking about a prime - but that just reflects the images I take with my set up. I bought the 12-35 and also the 35-100, in order to give me range and flexibility for holiday and street stuff. I'll add a couple of primes later on.

    If I were going long (our definition of long might be different) I go with either the 75-300 Oly or the PL100-400. The Oly is small and very good for most subjects and the PL100-400 is extremely good IMHO. Don't discount the f4-5.6 version of the the 35-100 as it is very good at the used prices.

    Why not the Panny f 2.8 35-100. It is fairly light. And it gives double IS with the GX8. This would give a truly killer combo.

    If you crop a 20MP image taken with a 42mm to the same FOV as a 140mm, you will be left with about 2MP of resolution and the noise performance of an average cell phone camera.

    Try a few of your proposed crops and I think you'll answer your own question.

    The only way they'll get my 14-140mm lens is to pry it from my cold, dead, hands. (Apologies to Charlton Heston) Your issue with the 12-35 vs the 14-140 is easily solved. Ditch the kit lens and replace it with a 9-18mm (my choice) or the 12/2. These are both very small lenses and readily pocketable.

    For longer, I have had the 100-300mm and now have a recently-arrived 100-400mm bought specifically for an African trip this month. I'm pretty sure I'll be selling the 100-400 when I return, though. I rarely have need of its long focal length and it is so big and heavy that it almost makes a joke of the M43 "small and light weight" theory.

    It doesn't look like Panasonic offers the 14-140 weather sealed. That's a shame because I really like my E-M5ii with the Oly 14-150. It's slow, but for architecture from a tripod it's fine.

    It's a GX8, with IBIS. Unless you need stabilised video, the sealed 14-150 will work just fine.

    I agree. I loooove my 14-140 , it always surprises me with the quality of pics it can take. However I think you're mixing up his lenses, I think he has the 12-35 f2.8 pro , not the 12-32mm kit lens. Considering the size of the 12-35 f2.8 I can see why he wouldn't want to carry both :)

    I have a GX8 and yes, it has IBIS, but it's only about as effective as the IBIS in the old Olympus E-PL2 (not very).

    Sell the GX8 and get an EM1 to pair with the ZD 150mm f/2.0 :dance4:

    Thanks guys, you guys really got me convinced on the 14-140!
    Another alternative kit that I'm thinking (let's say for travel) is 14-140 with the Leica 15/1.7. They do overlap in focal length, but then I do need a bright lens sometimes. Of course, there's always time and place for everything, and there still will be times when I need the 12-35 2.8 instead of the aforementioned combo.

    yeah thats a good idea. My walk-around kit used to be the 14-140mm for general purpose daylight shooting and an Oly 25mm f.18 for lowlight and artistic close up shots with lots of bokeh. Ah the simple days of a 2 lens setup :p

    The Panasonic 35-100 4-5.6 is a slow but sharp lens. It's barely larger than a prime and light. I use mine quite a bit because it fits so well on the EM5 ii and the E-PL7.

    yeah I continue to be amazed by what this supposedly 'lowly zoom' lens can produce. GX8, 14-140mm @140mm f5.6 iso800
