DA* 50-135mm or DA 70mm limited?

hi guys,

can someone give me some suggestion? which one to buy, 50--135 or 70?

the 50--135 is an excellent lens. But the problem is that it's too heavy, and since I don't shoot birds or concerts that often... I don't think I really need that long reach of 135mm.

70mm is cheaper, smaller and maybe has tiny bit better performance, but I lose the WR and the other thing is that when I used my 16--50, I sometimes find that 50 is not far enough, 70 is not much a difference actually.

thanks for all inputs!

You wrote down all the obvious differences. You can use you 50-135 to test whether 70mm is good/enough for your needs. The 70mm is really a small lense but not so flexible. Another difference is the bokeh. There I would say, best ones are the 77mm, then the 50mm f1,4 lenses and then the 70/50-135.
I would say the image quality of the two lenses is quite similar. One is more flexible and heavier, the other one is inflexible but small/lightweight.

To me the first question to answer for yourself is zoom or prime? I'll assume you're okay with the prime so let's look at your concerns with the two lenses

DA70: focal length (too short) and loss of WR
DA*50-135: size and weight

It seems to me that the D FA Macro 100/2.8 WR solves all of these issues and gives you the bonus of 1:1 macro. It's intermediate in size to the two lenses but small enough that assuming size isn't the primary concern it should be fine. Don't be fooled by the DA70's size, the lens hood is not retractable and adds a significant length to what's indicated in the official specs. It's price is only a little more than the DA70, much less than the zoom. It's got WR. Problem solved!

I have both and use both. Both have the same IQ to my eyes. You've hit on the differences, and only you can decide what is the best choice.

In hindsight though, if I'd known I was going to buy the DA*50-135 then I would have bought the FA77 instead of the DA70 as there is a greater differentiation between the 77 & zoom (colours/look, bokeh, speed) than the 70 & zoom.

Is this going to be a portrait lens?

I think the DFA 100 WR macro suggestion is completely logical... just give it a test run to see if you like the rendering of the 100 for portraits. It's incredibly sharp... maybe too sharp for a flattering portrait.

Realistically, the DA 70 and 50-135 have completely different applications, and it will be the purpose of the lens which will determine whether it is worth keeping the DA*. If you want to shoot portraits, the 70 should be a good length, but if you need weather resistance and reach, the macro is a better choice in my opinion.

I think DA* 55 1.4 is very good for portrait because of its sharpness, image quality and specially creamy bokeh. So I also tend to buy the new one. Any of you use it?

Sounds like you have a question on your own and not an advise to shang.

If so, please start a new thread for your question; in general it's considered impolite to hijack somebody else's thread.

For me, it confused me (why advise 55mm if shang already has 50mm) till I saw the end of your post ("Any of you use it? ").

70mm is cheaper but just a bit. I saw it going for $450 to $500 here and 50-135mm for $600-650. I would pick 50-135mm any day due to flexibility and 70mm is just a bit (half stop) faster.

As someone mentioned, 77mm would be a wiser choice IMO.

vieA third vote for the D FA 100/2.8 WR, because of the field of view (compliments a 50) and the WR.

thanks a lot, guys! I think I will keep the DA*, though my copy seems to have some back focus problems... I am not sure if it's my K-7's fault or the lens'...

DFA100mm must be wonderful, but the reason that I didn't consider it is that I don't like the look of the lens... don't laugh at me pls
