Recession, what recession?

I think of it as saving my children from wasting their inheritance on unnecessary items that they probably wouldn't use. I can do that just as easily as they can.

Right abouts now, I'd say some people would be better off pulling all thier investments out of the markets and trying the Casinos....about the same risks and rewards, but alot more entertainment, and usually a free buffet...
Fired many shots. Didn't kill anything.

You mean like Canon gear?

Hi folks, I've got mine at last, it was hard waiting all week b4 I could get to the shop but I just didn't fancy it being bounced around in a delivery van so I waited a little longer !

OK I can share a few shots from the 60-250 now, make of them what you will

Firstly I felt I should check the focus adjustment for this combination of lens and camera, most of my lenses seem to need about +100um on my K10.

All were tripod mounted with 2s mirror lock up (although note that my tripod isnít the sturdiest in the world and I felt there may have been some residual oscillation from shutter press on occasion Ė would be nice to have a remote).

I looked at the two extremes of focal length :- 250mm at f4, 60mm at f4, procedure was to re-focus using AF button after change of um, shutter button set to not AF. I did this in 20um steps from 60 to 160um.

The 250mm shots were taken at about 8ft away, the 60mm shots closer to get approx same scene.

Shots here are processed at silkypix default settings, resized to 968*648 plus usm 100, 0.8, 6. http://s210.photobucket.com/albums/bb217/k10dbucket/DA60to250focuschecks/

Shots here are 100% crops, just processed at silkypix default settings, no usm. http://s210.photobucket.com/albums/bb217/k10dbucket/DA60to250100pccropfocuscheck...

I chose 120um as the adjustment to use.

maybe I'll use a test chart later, I was just keen to get going !

Next a few snaps from Sunday afternoon at a selection of focal lengths (all with the 120um adjustment).

Sorry the shots are not much good, for some reason I just wasnít feeling inspired at the time, I think I was looking for a particular shot rather than going with the flow !

I wouldnít usually shoot so many at f4ish, but I wanted to explore how the lens behaved. I think Iíll try and do a MLU f# series later.

Some have had tweaks to EV and highlight compensation applied but white balance, contrast, colour etc are unchanged (Bluebell ones really need some colour adjustment IMHO to remove green cast due to foliage), all are resized to 968*648 with usm 100, 0.8, 6 applied. Those annotated MLU in the album are tripod mounted and have 2sec mirror lock up. All taken with camera settings for contrast etc at 0 but bright mode selected (I canít remember now if that affects silkypix in any way) All originals were PEF raw files, sRGB.

Iíll try to add a few later from an f.no series of what I suspect could now be the most photographed pub in Britain

Comments welcome, I haven't finished testing this lens yet so my jury is undecided at present.

PS Hats off to Mr Day for his definitive series in another forum.

I wish SRS would hurry up and sell out of their current stock, no matter what I tell myself I am still thinking of buying one while they are at the lower price and selling on my Sigma 70-200mm f2.8.

Something I have just noticed. When turning the zoom ring from about "235" mm to 250 mm , I can see very minimal movement on the zoom extension, but it does move. However, through the viewfinder, there appears to be no change in zoom length this final bit !

Anyone else confirm what they see ?

Just received mine this afternoon, I noticed this issue as well. I guess we should call it 60-235mm rather than 60-250mm.

Well the exif says 250 at full zoom. Unfortunately I dont have another 250 mm lens to do a comparison shot.

There are not many zoom lenses that are actually the same as the nominal value in the name. A 60-250mm could easily be a 63-240mm.

Don't forget that many lenses also change focal length as they are refocused, so try the lens at different distances to see if it varies. Close up focal lengths may well be shorter.
Best regards, John

Comparative shots

DA 55-300 @ 210mm




DA*60-250 @ 250mm




DA 55-300 @ 260mm




DA 55-300 @ 300mm




From the above, it would seem that the 250 setting is about right. Not conclusive of course, but reasonable. Only an accurate angular measurement would be specific.

To be brutally honest unless you are a pixel peeper there is really nothing in it when you compare the 2 in good light, certainly your average person wouldnt be able to tell the difference on a medium sized print. The 60-250mm has the bonus of being faster with weather sealing and SDM but imo it shows how good the 55-300mm is (espacially for the price difference).

I still think the 60-250mm should have been f2.8.

Looking at a distant object, mine does zoom smoothly out to the max image. The focal length data on the camera steps from 220mm to 250, so I checked the image at the point of change and there is still a slight difference between it and the final 250mm image size.

At close object distances (2m) there is virtually no noticeable change.

Richard, Thanks for all the tests you've done on these lenses, must
have taken quite some time with the uploading as well.

Cheers
