E510 with 300/f4.5 OM Zuiko

[boochap]

Not impressed with the sharpness...



lens mounted on arca swiss ballhead, at 1/80sec, f8. cropped 2x.

i thought this is supposed to be a very sharp lens... sensor's fault??

anyway, thanks to made in china, my 4/3 adaptor only cost US$20.

Did you shot RAW?

IS?

BTW looks decent to me ..... if anything a little underexposed .....

[bousozoku]

It looks okay, but let's see: adapter, cheap adapter, 35mm film-oriented lens on adapter on digital camera meant for digital-only lenses...what could be wrong?

[spidey89]

seems ok to me too,i used the 70-300 no problems at all

[egnaro]

wow u have a very high expectation... look nice to me actually

[boochap]

Thanks!

Brightness is dependent on your screen brightness setting.

ASA at 100.
Shot RAW.
IS was on.
Heavy duty tripod and ballhead.
f stop was small.
Shutter was above 1/60sec.
Self timer was on.

I supposed it's the sensor limitation, or if anything else, the 2x cropping.

Do you have another similar picture shot with a "better" sensor without any cropping for comparison?

And you do know that the OM lens that you used was not designed for the digital body that you used it on

[olymac]

Oh ..... and of course you do know that the 4/3 system with digital specific lens actually shoots full frame WITHOUT cropping ......

[boochap]

Ayooyo. Don;t be xcited. I am not comparing anything, nor saying Oly is no good. I am juz not impressed with the sharpness.. if something is wrong with my camera setting please help me.

I am OM user and collector, new to digital SLR. E510 is my first DSLR.. as much as OM-1 was my first SLR.

Optically, a focal point is supposed to be sharp on whatever surface u focus, be it film or electronic surfaces. Does it got anything to do with lens designed or not designed for digital, i don't know? The colors, satuations, contrast, etc, may be different, i agree, between D and non-D Oly lenses. What explains the craze over super sharp leica lenses with digital RD-1 and other DSLRs with M mount adaptors? Leica lenses were designed for films.


Focal length is 2x factor on a 4/3 system? so 300mm lens is equiv to 600mm on the 4/3.

To get this kind of moon size wthout cropping, u will need a 600mm lens.. have we had a digital specific 600mm lens for 4/3 yet? So if u use the digital specific Zuiko ED 300mm F2.8 -------- $11,000 (Built to order), u will still need to crop 2x.

There are just so many points to clarify in your reply

[Kirika]

BTW...my recommendation is to turn your IS off if you're mounting the camera on a solid tripod. I don't think the IS would be helping much. Don't forget your mirror lock up and timer. Preferably with shutter release.

[Jason Ong]

Yupz Kirika's right and also using some om adapters if not all, there is a chance to focus pass infinity, so you should not focus all the way to the "infinity" marked on the lens. In fact you have to turn it back a little. That's what happened to mine and some others on CS. But the best bet is to try it out yourself at different focus length close to "infinity" and see for yourself

[boochap]

Thank you all for the suggestions. I always appreciate practical advise than the theoreticals.

I didnt know E510 has a mirror lock up?! I thought this was already a forgotten function after they decided to go digital.

Let me go try again when the sky is clearer.

I believe its now called Anti-Shock. Why they couldn't just call it mirrorlock up is beyond me, but it is the same thing.

[viewwing]

try focusing with your liveview with 10x also... that will help u get the sharpest possible focus.

And also use the optimum aperture for ur lens... Can open the shutter longer to compensate the smaller aperture. Hope you get a better shot

[Kirika]

Haha. For these applications, I occasionally use "focus bracketing". I don't really trust 10x LV for moon shots 'coz of the graininess of LV boost. It's undoubtedly great in the daytime. Anyway, I'd focus till I think it looks good, then take a couple shots with focus fine-tuned up and down. And yeah...the optimum aperture is a good thing to have, too. Aperture bracketing with focus bracketing, anyone? haha.

[casey4355]

normall for such shots, i use IS off and anti-shock.

I remembered the E-500 had focus bracketing! I wondered why they got rid of it after the E-500. It can be really useful .

Focus bracketing for moon shots ?!?!

Change the adapter or send the lens in for servicing or both if the shots are not focused at infinity
