60-250mm vs 300mm at long end?

I was wondering if anyone could give me their thoughts on this... I have the 60-250mm and love it. The only thing that bothers me is at close distance, it hardly gives me any better magnification over my 50-135. Focus on anything far away, then the lens really shows what it can do. That's some heavy focus breathing!

Does the 60-250mm really do 250mm? How does it compare to the DA* 300mm for the long end? Would the DA* 300mm really be worth it to get really close up on a subject indoors vs the 60-250?

Can anyone with both photograph and compare? Perhaps be so kind as to post photos? Thanks a billion for any help.

The DA*50-135 actually gives you a little more magnification than the DA*60-250; it's so little that it can actually be ignored (both are around 1:6). Check the specs. DA*300 gives a bit more magnification (1:4). Your limitation is actually the minimum focusing distance of those lenses, not the focal length.

If you really want closeups indoors, get a macro lens 1:1 magnification at short distance (DFA100WR, 30cm) to very short distance (DA35Ltd, 14cm).

The 60-250 has IF (internal focusing). Basically all lenses with IF will decrease in effective focal length at near distances.

I worked it out in another discussion somewhere that is according to its magnification and minimum focus distance specs its only 125mm !!! at MFD and zoomed to 250mm.

Using the same calcilation from the specs page the DA*300 at MFD seems to be equivalent to 219mm.

Yes really does the 250mm still at f4.

Assuming that you ean the Sigma 300mm f2.8... Then the Sigma gets you 1.2x closer but at a considerably better aperature. Not sure off hand what the close focusing distances and rations are when comparing both though.

For true close up I'd consider the Sigma 150mm macro (at about eleven hundred retail) or even waiting for the Sigma 180mm macro. Even the Pentax 100mm macro is impressive.

Although my Tammy 70-200/2.8 is my fav glass for walking about and getting occassional bug/flower closeups, I discovered how well the da*300 can do when returning home and finding a Robber Fly blocking the door. Handheld (and SR accidently turned off), pop-up flash due to dark entrance and I was highly impressed with the results.



I have used the da*60-250mm but never shot a closeup like this with it.

Thanks for the info. Yeah, it's pretty close. My main concern was not macro level shooting, but a close headshot during a press conference or limited space. I just don't get any better a result with the 60-250 than I do the 50-135 sometimes.

Thanks for that info. So then my old FA80-200 would not have this issue?

This is exactly what I was in need of! Thanks so much for this! It seems that the DA*300 will be bought.

Thanks for that! I never knew you could get so close with the 300. Very nice shot!

The DA*300 can get you very close - here is one at max magnification (no cropping):



The DA*300 is the ultimate butterfly, dragonfly and flower bud lens...

The old FA 80-200/2.8 is also IF and will exhibit the same behaviour. But it won't be so obvious, as it gives you a lower max. magnification anyway (x 0.19).

I wish it were the 2.8! I should have been more clear. Sorry about that. It's the 4-5.6/80-200mm. :-(

That is correct regarding aperture, but the range only reaches 250mm at infinity focus. As shown in Steve1307's calculations, the 60-250 has a field of view like a 125mm lens at its minimum focus distance. In between infinity and MFD, FOV varies proportionately. The DA*300mm is also an IF lens, but focal length does not vary as much with focus, probably because it's a fixed focal length lens.

Finally did the test. Using catch in focus at minimum focal distance for both lenses. No cropping of course.
Absolutely no question you get *much* more magnification with the DA*300.

Thanks for the test Sandy. The magnification on the DA 300 is pretty useful.

As Joe mentioned above - the DA*300 is the ultimate lens for Dragons & Damsels, Butterflies and insects of that size.
