Just got 100mm F2.8 Macro, should I keep my old 50mm Macro?

After searching for a macro lens (and getting a lot of help from folks around here!) I was able to secure a new DFA 100mm WR macro as well as a used M 50mm F4 Macro, both for pretty good prices. Now I'm torn, I could sell the 50mm at a profit but part of me wants to hold on to it. What can the 50mm F4 do better than the new 100mm 2.8?

Thanks in advance for the thoughts, this has been a great place to get questions answered!

Size? Do you need the money now? If you need the money now for something else and you know that you won't be touching the 50 anymore, then I would sell it. If that's not the case, I would keep it for now. think of it as an investment. Cause from what I see, the value of legacy lenses are not going down, but instead going up. (Well it depends on the lens.)

It's a lighter walk-around macro.

And you can use it with extension tubes that don't have the A-lens connection.

It's lighter and wider AND it's Manual Focus - a focus mode that you normally use in macro shooting.

Not that the DFA100 can't manual focus, it's just easier with MF lenses. Personally, I prefer MF lenses for macro shoots.

I mean, who doesn't need money?? Are there other things I could do with the money? Yes. Will I have to cancel or forgo something if I keep it? Not really. I got it for $50 with caps and original bag and it looks almost brand new. Thus more indecision!

I have both a 50mm and 100mm macro and like to have both.

Outdoor macro shooting usually demands a longer lens where the 100mm fits nicely. But if you do any close-up work indoors (table top work), the 50mm is nice. I use my 50mm during winter/inclement weather when I am stuck inside - it's fun to just grab some items from around the house and do close-ups. This is where the 50mm shines as I don't have a lot of room to move back away from my subject.

I kept my 50mm as it allows you to be far closer to subject than the 100 does, for 50.00 bucks you probably wont replace it as cheaply again if you do decide to sell, but, if you need the cash, and dont see a use for it, sell, its all on how you shoot and how often you think you'll actually need it.

All my macros are MF. I first got the Vivitar-Komine 90/2.8 macro (cheap!) and much later the MacTak 50/4 (1:1) and then a vintage 40/3.5 (1:2). The 50 and the 90 are quite different beasts, the 50 being small and great for inside shooting, the 90 being heavy and great for outside work. Neither replaces the other; they supplement, as do the various other macro setups I use (enlarger and reversed lenses, etc).

What can an MF 50 do that an AF 100 can't? Allow|force closer work. Give a wider FOV. Poke into smaller spaces. I wander around homes of friends and family shooting wee tiny knick-knacks with the 50. I wander around gardens and villages shooting various small things with my 90, or with 75-105-140mm enlarger lenses on extension. In my mini-studio, I shoot stuff with the 50 or even the 40 because I can't back-up far enough for a 75 or anything longer.

So it depends on the spaces you have available to shoot in. I say, keep the 50.

I have both the A 100/2.8 macro and the M 50/4 macro.

I don't use the 50 often but it's nice to have when the need arises.

An often overlooked difference between lens focal lengths is 'perspective'. Note the inclusion of more of the background with the wider lens which allows you to retain more OoF area (bokeh) in the background while keeping subject size the same -- a consideration in composing the scene.

It's important to pre-visualize the background as changes in the point-of-view of the scene aren't accomplished in post-processing, but through the choice of lens FL during "pre-processing".

Great illustration - makes it easy to see the difference in background area as you say.

+1

I kept them all (M50/4, A50/2.8, VIV55/2.8).

MF is usually easier with MF lenses. But with macro lenses, in particular the DFA WR, it's just as easy as with a Mf lens.

To answer the original question, I had a FA50 macro and I then got a DFA WR macro. I decided pretty fast to sell the 50, as I wasn't using it anymore. I also have a F50 f1,7 so the duplicate FL didn't make sense, plus I had stopped using the 50 altogether.

So my advice is, keep it for a while, see if you really do use it, otherwise sell it.

Incidentally, getting the DFA 100 WR macro also means I've almost stopped using my FA100-300...
