I already have the Panasonic 35-100, should I get the 75/1.8?

    Sometimes I feel a bit tempted by the 75/1.8, it seems to be such a great lens. On the other hand I already have the 35-100/2.8, which isn't exactly a bad lens. Does anyone have both, and for a good reason?

    Here are my thoughts on the issue.

    The 75 is one of the sharpest lenses available for any camera system, but the panasonic cannot be called soft by any standard.

    The 75 is more than a stop faster, but f/2.8 isn't slow. I'll roughly double the shutter speed in the same light, and I'll get shallower DOF. However DOF is already rather shallow at f/2.8 with such a long lens.

    The 75 is built like a tank, the Panasonic is nearly built like a tank.

    THe 75 isn't weather sealed, the 35-100 is. But I guess any lens that's built like a tank can withstand a little moisture anyway.

    The 75 is smaller and lighter, but two lenses with similar specs weigh more than one.

    Filling up holes in my lens range probably makes more sense than getting another plug to the same hole, giving that my supply of money isn't infinite.

    Any thoughts? Did I miss anything? Oh yes, the black 75 looks gorgeous on the EM-1. Well well, the important bit is getting nice photos, having gear that looks good is second priority.

    I have both. I had the 75mm first and then later bought the 35-100 with the thought that I might be able to then sell the 75. But it didn't happen and isn't gonna. One of my main uses for this type of lens is shooting candids of friends and family, often indoors in fairly to very low light. That one or one and a third stop advantage of the f1.8 aperture on the 75 can be huge in those circumstances. Over the most recent Thanksgiving and end of year holidays, I started off trying to get by using the 35-100. I had too many shots with motion blur. I pulled out the 75mm and almost never missed a shot. That doubling plus of shutter speeds matters a lot at a certain point in low light, and it's a point I seem to hit fairly often in those indoor and/or evening get-togethers.

    I really like the 35-100 too, though, because it's a more versatile lens, good for moving subjects in decent to good light, and good for static subjects in almost any light with today's sensors. And particularly with the Oly 5-axis IBIS. So I'm keeping both. If I was going to get rid of one, it would be the 35-100 because the 75 will get me shots I've just GOTTA get and the 35-100 sometimes doesn't. And I can do a reasonable job on the tasks that the 35-100 is better for with the 75 - I did it for quite a while. But I'm glad to have both - they're both fine lenses and telephoto and ultra wide is the only part of my m43 kit I seem to ever use anymore, so these are two great lenses to have.

    If the f2.8 seems shallow & about the least dof you want/tolerate, I don't see advantage to f1.8 & would require careful perspective, framing, composition vs. a 25mm at f1.4 would. See where used ones are at with price gives idea of try it for few months cost (if get new one).

    My main hole in the lineup is a fast tele that's longer than 100 but shorter than 350 (my 500 f/4 doubles as a 350/2.8 when I use the speed booster). I'm currently a bit torn between the 50-200 and the 150/2. Also I'd like to get one of the 7-14 lenses.

    I have the 35-100, it is one of the most useful zoom ranges next to the 12-35. I intend to keep mine, and add a 75 somewhere along the way. I think they can co-exist and each has its own distinct advantage over the other. :biggrin:

    i find the narrow angle of view incredibly hard to use. too tight. its a bit $teep for a lens to have just for the sake of having it.

    if it fits your shooting its one of the best for the system

    You could always try one of the manual 85mm lenses, like the Rokinon or an older legacy lens. Similar FOV and speed.

    There are also some c-mount 75mm lenses that can be found on ebay from time to time at a good price. The Computar and Cosmicar branded ones supposedly work without vignetting.

    a cheap but sharp 100mm F2.8 legacy lens with a focal reducer is a good alternative for having a 75mm F2.0... My SMC takumar 105mm f2.8 is incredibly sharp with cheap focal reducer and it's like having a 75mm F2.0

    Why not the Oly 45? Same speed, but a more versatile focal length.

    I have the 45 and the 75. I was at a concert where the 45 made more sense from a framing perspective, but even looking at the preview shots, I reached back for the 75mm. Some lenses transcend the logic of comparing specs and the 75mm is one of those lenses. My suggestion is to try it (e.g., in the store or by borrowing or renting). There is something magical about the 75 - its by far my favorite lens. I have the P20, P25, O45, O75, O14-140, and P14-42 X.

    I haven't been paying much attention to the lens road maps/rumors lately. Is either Panasonic or Olympus planning something like a 100mm f2 or f2.8 prime?

    I have both as well and I agree the 75 is the better lens. Saying that though I suggested the 45 because it is more versatile and the 45 is by no means a bad lens. It sounded like the OP was not sure if he needed the 75. $900 bucks is a lot of money to throw at something you are not sure if you even need, especially if he already has the excellent 35-100.

    I think its a matter of taste. I've never really bonded with the 45's focal length, although I'm getting a little better at it. 100 mm on APS-C and 135 on FF (so 60-80 range MFT), however, have yielded some of my absolute favourite shots over the years.

    I had both but sold the panasonic 35-100mm. Dont always shoot telephoto but when I do, I prefer using the 75mm or the 45mm.

    The 75mm is a superb lens and I find myself using it even though that shot may not require. Just put the lens on and try to make it work. Haha

    That's a well laid out answer. I have both and pretty much agree with everything you've said. I'd add that the 35-100 fits the bill as an excellent stand in for the 75 when the circumstances doesn't lend itself to the 75 - in my case the wife and I attend several renaissance fairs each year and the 35-100 works really well for the various locations where it's not so easy to either get closer or back up. All that said, the 75 is one of those lens you look for excuses to shoot with.

    Yes, and your post is well-said, too. I thought I would sell the 75/1.8 when I got the 35-100/2.8, but it's still here. :smile:
