I though it may be of interest to have somewhere to share images testing the sharpness of this combo, so I'll kick of with a few from my shoot on Mudeford Quay (it wasn't just bird shooting :) )

Across the harbour bay to local housing (what a cracking location to live). Its around a quarter mile away from where I am standing.

An amazing lens. Nice shots too, I like #3. I've been using mine on 300mm a lot, trying to find fault, but the only fault I find is because I made mistakes ie camera shake, do to low shutter speed, do to me not paying attention.

I too use mine mainly at 300mm and am quite happy with results- considering that it's a zoom. What I would love is a m4/3 long telephoto prime, I sold my 300mm f2.8 because of the poor AF on the EM5 but to be honest I wouldn't want it back now to use on the EM1. A new smaller 300 f5.6 prime would be just what the Doctor ordered.

Some nice sheltered housing you have down there! Must get on the list! Love the red rowing boat!

Sorry Stephen, my poor use of English, this is not "Local Housing" in the sense of "Housing Association", but housing that is local to the area :o

Very expensive it is too

Its a wonderful area we live in down here, the main "problem" (apart from the "Summer Grockle Invasion") is that the place is full of "Olds" (like me), and that has really pushed up the price of housing)

On the other hand, this is only 10 minutes from my house, the New Forest is 15 minutes away and we have Salt Marshes within 10 mins as well - its heaven for a nature photographer *chr

Yes I to would love a long prime, I am sure that I read on this forum that there is a 100-300 F2.8 next year.

top of my want list in fact I would say that if there is a need list then it would be top of that too!

I hope not, I think f2.8 would be excessively large and expensive - not my ideal m4/3 lens!

I think this is the sharpest image that I have obtained , not in the same league as other images on this thread sadly!

Nothing wrong with that image dogsbody (sorry I haven't got your real name) The colour is fantastic even down to the green tinge between the black and brown feathers above the wing. It's an amazing camera and lens combo and producing super images.

Brian, Top class images again. the EM1 and the 75-300 are working a treatf or you. I like the image of the boat on it's own. True to form I would be different than everyone else!! One man's trash is another man's treasure, or something like that. In saying that they're all super. *yes

Thank you Conor, The Greenfinch is better than the Moorhen. The lighting at the time was exceptional, it was an hour or so that made me very happy indeed and not just from a photographers perspective. If the sun shone more in Winter it would be so much nicer.

Jonathan, how big a crop is the moorhen? I get the impression that there is a bit of movement blur (as it all appears the same level of "out of focus") which has been compounded by being cropped and then blown up a little (either that or you used the DTC? )

The finch (chaffinch?) looks much better detailed but you have great colour in both shots

Thanks Brian,

I think that there is about a 30% crop in the Moorhen image, and looking at it now yes I can see the movement blur.

It may be my eyes or contact lenses but it seems to be sharper on flickr !

DTC was used in both and I would estimate the distance of the birds to be 20 yards.

For the Moorhen image I had IS set to Auto, but following advice on this forum it has since been set it to IS-1 (and was used for the finch) which does seem to gain a sharper image.

many thanks Brian, your images do give me something to aspire to, as do many others on this forum!

I have never been happy with the results using DTC (although I have seen others get good results).

I seem to get sharper images with less artefacts by shooting without DTC then cropping, maybe give it a go if you haven't made the comparison and see what you think

This was shot at f/10 and definitely will have lost sharpness as a result. Be brave - you can shoot wide open :)

I endeavour to shoot wide open as much as I can but when using S priority (for birdies) and auto ISO sometimes a smaller aperture is dialled in automatically. I do however use a smaller aperture for macro work, happy to accept diffraction degradation to get the DoF.

Yes - diffraction does seem to have less of an impact with macro work - possibly because we don't have the same expectation of detail because we don't see macro subjects with the naked eye :)

Thanks Brian,

In my days as a 'clay shooter' I used to fire at a pattern plate with different size cartridges and chokes (that control the pattern of the shot) just to see the differences in the spread and pattern of the shot. The benefit being that it would provide an understanding of what the shot would do and; whilst moving around a shooting ground from target to target I could change 'settings' (cartridges and chokes)n to suit. It seems strange that until now I had not considered similar tests with a camera. Of course the options and settings on a camera are vast in comparison to that of a 12 gauge beretta!

Thank you for your help it is appreciated. Normally I shoot birds on
M,
1/1000
ISO Auto
WB Auto
F10
Vivid
IS-1
Contrast +1

Brian I am interested to see that you select S and I think from previous posts a lowest of 1/640 aiming for 1/1000.

Do you think that I am over complicating the issue by using M?

Hi David.

the article was on this form and is here http://www.imaging-resource.com/news/2013/10/24/qa-with-olympus-president-haruo-ogawa-and-planning-manager-eiji-shirota-as?utm_source=newsletter&utm_medium=email&utm_campaign=2013-11-01

but, the rest I got completely wrong! it is a 40-150mm lens, apologies to anybody that became confused, but I imagine that some may have chuckled at my expense!

I wonder how that would cope with BIF, any thoughts?

brian1208

Not at all, depending on the conditions I will use A, S or M.

If the lighting is fairly constant I also tend to stick it in M and set the shutter speed and aperture where I want them then juggle ISO to get the exposure

Otherwise I select which ever mode will suit but the one thing I am now totally convinced of is the need for those high shutter speeds to get the results I am after .

(Strange about the shooting analogy, I used to target shoot when I was a sea-cadet, using a Lee-Enfield 303 choked down to use .22 rounds so I guess that may be why I have a fondness for using precise single point technique :) )

David Morison
18th November 2013, 07:51 PM
I don't know how the proposed 40-150mm will cope with BIF but reducing focal length will always improve AF performance on fast moving objects. My Leica 14-150mm (despite being 4/3) AFs better on BIFs than the 75-300mm @ 300. It goes without saying however that the detail lost by using a shorter FL can never be recovered.

Regarding M mode, I do sometimes use this but you don't then have the option of dialling in exposure compensation for subjects against a light/dark background. The best way to use M mode is when estimating exposure using a separate hand-held exposure meter and incident lighting, then background luminance plays no part. But that's going back to techniques used several decades ago - works though!

not me, I just find a nice open piece of grass under the ambient light conditions, defocus and use that as a giant grey card (can't remember who taught me that grass is grey but it works a treat :) )

Good idea, I am not often near such grass but I must definitely give that a try!

its the next lens on my buy list.

It will be excellent for trackside shooting of motorcycle and grass track racing and also for most of the shots I get at places like the Hawk Conservancy.

The addition of a 1.4xTC would also be a must have

Its going to be hard to wait patiently but at least it gives a bit more time to acquire the necessary funds

Were there any informed guesstimates on price Ian?
