Product Description

The Lumix G X Vario 35-100mm F2.8 is Panasonic’s premium fast telephoto zoom for Micro Four Thirds, and a natural companion for the 12-35mm F2.8 OIS. It features ‘Power OIS’ optical image stabilization, and has a nearly silent focus motor for movie work that’s also extremely fast.

    Very good lens

    Have used the 35-100mm f2.8 for six months and it has become my favourite tele lens. Optical quality is far superior to the other Lumix tele-zooms I own (14-140, 45-200, 100-300, 45-175) and the wider aperture is really helpful in many situations, including low light as well as ease of focusing. Images are generally sharp to very sharp throughout with the only issues being some light fall-off towards the corners (noticeable, but not a real problem) and, like all the other Lumix tele-zooms, ...

Lumix 35-100/2.8 making strange noise

I just bought a brand new Lumix 35-100/2.8 lens. What bugs me is that the lens is making a tiny weird sound all the time it’s on. Something like the focus motor, but not quite. I have tried to turn off the OIS and switch to the manual focus mode to make sure the lens is not supposed to do anything. I have also tried a different body, the sound is still there. I find it quite improbable that the lens should make any sound at all under these circumstances, should I claim a replacement?

Mine is completely silent on my EM5 except at power up, or acquiring focus, there is a light whoosh noise.  I would get the seller to swap it out for a new unit.  It is a great lens. Continue Reading

The sound is hard to record, as it’s just audible with my head close to the camera. This is the best I have got, after amplification: So it’s no back-and-forth “woosh” of the focus motor, more like steady chirping. Continue Reading

Mine 35-100 makes a little noise as well. I can hear it with the canera on the eye but no else. No problem with video. On the other hand I'd sent the Pana12-35/2.8 to the service because of the sound of the apperture that is quite noisy (when shooting in silent mode wíth electronic shutter). But they answerwed that is not beyond the limit. And lens of my friend makes the same noise. I shall use f2.8 to prevent sound (it still make little noise when zooming, because it is not real constant apperture) 35-100 lens is much better in this way - probably it has smaller apperture. BTW I would appreciate if Pannasonic allows more open ap. on the wide end, because these lenses are definitelly capable for it. Continue Reading

Your thoughts and experience: Oly 75mm or Pana 35-100?

Hi everyone. I'm ready to purchase a new tele lens for my m4/3 set-up (GX1 and E-PM2, Pana 7-14, Pana 20, Pana 12-35, Oly 45). Thing is, I'm really torn between the Olympus 75mm f/1.8 prime and Panasonic's 35-100 f/2.8 zoom. My question relates to the real-life situations in which you have been using those lenses, and not to any sharpness/depth-of-field/image-stabilization issues - as you've noticed I have both Pana and Olympus bodies, I'm well aware of what kind of depth of field I get with m4/3, and for my usage most of the system's lenses at this level are plenty sharp and well-corrected for aberrations. Plus I've got Photoshop. I was thinking hard about getting the zoom, but then I researched a bit and realized that for about $400 less, if you figure the OEM lens hood in, the Olympus 75 does look like an appealing lens that would complement my set-up so that I could get roughly the same photography I'd get with the 35-100 zoom. *Roughly*. I already have 70mm equivalent covered ...

I own both. They are both phenomenal lenses, and the 75/1.8 might be the finest optic overall I've ever owned. However, if I could only keep one, it would be the 35-100 hands down. They are both very sharp lenses with great renderings, but the versatility of the 35-100 wins out for me. I bring my 75/1.8 in my bag when I know I'm going to be shooting portraits, or if I know I'm going to want telephoto with much shallower depth of field, but my 35-100 is in my bag EVERY day I bring my OM-D. Also, I use the 35-100 over the 75mm when in a studio setting, as I'm usually shooting at around f/5.6, and there the 75 is really no sharper, so I simply gain flexibility and lose nothing.  It is very sharp at all focal lengths and all apertures, autofocus is extremely fast and accurate, and it's weathersealed. I've done reviews of both, if you're interested: 75mm: 35-100: ... Continue Reading

I have both and there is almost no similarity in use. The 75/1.8 is used when I know I'll need a bright mid tele, such as concerts, shows etc. Aslo I also like to shoot primes when I fancy the challenge of a single focal length to help develop my seeing eye (and trust me, it needs help). The 35-100/2.8 is a walkabout lens for when I expect to need a variety of focal lengths from shot to shot. I went to temple fund-raiser on Friday and took the 7-14/4, 20/1.7 and 35-100. The temple was dull, essentially still in the planning stages and nothing to photograph. So I took a walk around the surrounding bushland and kept the 35-100 on the whole time: Here's a few images from the walk, not as a recommendation for the lens, just an example of the varying FLs on the walk:  100mm  93mm  68mm  35mm  46mm 100mm 100mm For the last two, even the 100mm wasn't enough and the images are cropped. I like having both lenses. If you feel you may eventually want both lenses, my advice would be to go ... Continue Reading

It seems to me that your decision mostly boils down to the convenience of the Pany 35-100mm lens versus the speed of the Olympus lens -- they are both razor sharp, and in real world use a viewer couldn't tell whether an image was captured with one or the other using the same aperture. I don't own the 75mm, but I do own the 35-100mm -- because I shoot mostly corporate events, and portraits professionally. The zoom make way more sense for my needs. I do a lot of head and shoulder portraits and being able to get consistent in-camera crops without moving my tripod around constantly is a no-brainer for me. I don't like shooting commercial portraits any wider than f/2.8-f/4 anyway, because I don't want a client's eyes in focus and their nose out of focus. Also, I shoot a lot of low light, ambient boardroom/classroom sessions where flash would be a distraction and my moving about needs to be at a minimum -- the 35-100mm combined with the high ISO performance of my E-M5 allows me to ...
