I've made a few bob selling some of my old kit and am once again mulling over getting the 75-300mk2 to replace my 75-300

Whilst I am getting some very acceptable results with the mk1 I do find that when the light is a bit "Flarey" or coming from the forward of 45 degrees to the lens position it appears to be prone to loss of contrast and detail. (I've seen this again today when wandering around our local salt marshes.)

I see that the mk 2 has an improved anti-flare coating and reading sites like DXO see that it gets an increased rating in overall performance, particularly sharpness

I know several of you have the mk2 version of this lens so wondered what your thoughts were on this (particularly if anyone has made the swap I am considering)

Thanks in advance for any help

I've not made the swap from the Mk 1, and haven't used it in adverse conditions, but it seems crisp enough and fast to focus, which to my unscientific mind suggests a more even light distribution. Build quality is good, too.

I've wondered about this but I'm going to wait for the possible 300mm prime to come next year!

I too love the idea of this but worry about the cost (and to a lesser extent, how much its going to weigh)

I think that to a large extent will be decided by whether they go for an F2.8 or an F4, releasing both would be a good idea, the 2.8 for the Pro range, the F4 for the enthusiasts.

Brian I do not find lack of contrast a problem with the Mk2. but as I have never used the Mk1, I have nothing to compare with! However compared with the Panny 100-300 it is I would say very slightly more contrasty but not by enough to make much differenece.

Having recently spent some time using both lenses in Africa, I seemed to be reducing contrast after 09.00 AM! Especially against the parched whitish desert background! Your Mk1 might perform admirably in the African light!

It's all horses for courses, I reckon. But we are not that far away should you wish to try mine before investing? You would be more than welcome.

Sat thinking about this during two slow days at Upton House Craft Fair (worst sales ever! :( ) I decided to stick with what I have and put the money into my "pro-lens fund"

I'll probably go for the 12-40 when its more freely available then save up again for the 40-150 f2.8 later in the year

Thanks for all the input

Both of those lenses are on my wish list too!

What goes around comes around - I've just placed the order for the mk2! :)

Why? several reasons in the end:

- the manual zoom on my old copy (which was used when I got it) is very "sticky", reviewing my experiences from the HCT and the shoot on Mudeford Quay reminded me that I do like to use the SAF + MF option, for long shots of small birds in particular, and it is no longer easy to do so

- the zoom creep and extended lens wobble may, perhaps, play a part in those shots that aren't as sharp as I expect (I can feel a fair bit of play when holding the extended section of the tube)

- cash is available both for this and early next year for the 12-40 f2.8, if I spend it now the Government can't have it later (and better yet, neither can my two kids when I finally pop me clogs - long live "SKI'ing" :D )

Its going to have a hard act to follow though, as when it works, the old lens gives rather good results (rather like me come to think of it *chr )

So, the lens has arrived and firmware 1.1 is installed on my EM-1

First impressions of the new lens:

- build is excellent, no lens creep even with the hood on and manual focus is lovely and smooth. No barrel wobble at full extension

- hand-holding focus testing under limited lighting seems good, I'm getting sharp shots at 1/15th - 1/25th sec and 90 - 300mm fl. Its also performing well on my long range focus targets (I'll stick a few pics up later if anyone is interested)

- all of the above is, I guess, not surprising, considering the age of my mk 1 beast, there is a fair amount of play in the system

I will be interested to see if this is the repeated when I get out and manage a bit of BIF / Sport shooting (probably not until next week as we have another craft fair this week-end - at Highcliffe Castle, 11 - 4 both days should anyone be in the area :) )

Firmware 12.1. Blimey, I've got some catching up to do! ;)

I am glad you like the new lens so far Brian. I haven't got any complaints with mine.

lol @ 12.1 *chr

I seriously appreciated your previous logical post, which mirrored my thoughts exactly in the context of whether to get a 75-300 or wait for the 40-150 (I don't have the Mk 1 though, and have just let my 50-200 go so the 35-100/2 is my telephoto zoom now :rolleyes:

enjoy the new lens, and I hope the craft fairs go better for you over the next few weeks.

Oops, must have slipped into my time machine :o

I've corrected the typo *chr

so far, so good with the lens

(anyone want to buy an old and slightly worn lens for a very good price? :D )

here is the only one I could quickly lay my hands on. Original EM-1 + mk1 75-300 (I think the blur may be in part down to IS problems I was having, but it isn't as sharp)

Yes does a whole range of stuff, it's her hobby (been doing it for over 35 years) and she can do anything from the "sublime" (Limoges type flowers etc) to the cor blimey (two fat ladies as commissioned house sign, for no. 88 of course :) )

I'll stick some pics up on my website if you want a peek - let me know

Thank you Brian! A big difference between the two isn't there? It really is tempting me to follow your logical decision, and go for the MK II.
Thank you again

Now then lads, this is getting over-heated (on the kiln - geddit *yes )

indeed they will be Robins when they get their final paint job, Pam usually gives her work between 3 and 5 firings (up to 820 dg c) before its completed.

(Some of the "Posh stuff" gets 6 or more trips to the kiln before its done)

As requested, another pylon focus test, EM-5 + 75-300 at full stretch, in much better light last Summer, still not as good as the mk2 to my eye (as you can imagine, I don't make a habit of saving these as they are not really that interesting ;) so I had to scrape the barrel a bit to find them)

(another 100% crop)

Thank you again Brian. Certainly not as good as the MK2! I have a bit of thinking to do over the next few days, especially as it is probably my most used lens.

brian1208
28th November 2013, 05:43 PM
Don't forget we are only looking at one sample of each lens here, I'm sure that lens to lens variation will come into play too, but I do think DXOmark are right when they say that the mk2 is a bit sharper based on what I have seen here and on the web.

(I suspect the v1.1 update is also having an effect :) )

brian1208
28th November 2013, 07:29 PM
OK, here are a couple more comparisons at around 50ft using one of my other local focus test subjects.

Not precise obviously as done on different days, with different light and the mk2 shot with v1.1 loaded.

Pretty similar results at this closer distance to my eye, with the mark 1 being shot with f8 for 1/400th sec and the mk2 with f6.3 1/250th sec, both at 300mm hand-held

Both are 100% crops of a similar (but not the same) section, the key test in this trial is how well the LCD info can be read

the mk 2 is a bit more noisy as I was struggling with very poor light and under-exposed a bit, so had to pull it back to show the detail, at the expense of noise

mk 1

mk2 - correct image (just realised I put the wrong one up! :o )

tell me to stop if this is getting boring (it is for me so I guess it must be for you? ;) but if its helpful I will carry on with a few more )

this one is for Ron (and the others who commented upon my wife's bits ;) ) here she is at work on a matching tea bag holder, 1/25th sec at 75mm f6.3 hand-held

Brian, I am glad you posted these, it gives me the confidence to carry on using the Mk1 until the hoped for m43 prime makes an appearance. These as you say aren't a direct comparison - the Mk2 image has more noise evident.

David

brian1208
28th November 2013, 08:00 PM
yep, and Ian would say that using f8 rather than wide open probably started introducing a bit of diffraction softening etc.

I can only offer what poor examples I happen to have in me box - I never expected to make the change so didn't do a "Proper Job"
:D

EDIT: Sorry David, I've just spotted I put the wrong image up, I think the other one may have been one of the ISO1600 shots I did, I have put the correct image up for comparison now, the difference is still pretty insignificant but the noise level is better than before for the mk2 image
