Leica has never made a 1.4x with rom. It probably doesn't make a difference with the exception of the exif. The DMR will doe vignette correction and other magic with ROM lenses, but the 105-280mm is pretty well behaved and probably doesn't need this correction.Does anybody know if the lack of a ROM on the converter makes any difference in practice?
In general, Dave I prefer a matte screen for all lenses over 200 mm, although up to f 4.0 or so, the microprism screen is very good to use too. But at 5.6 the microprisms clog up and a matte screen is the only option.As a matter of interest does the 280/2.8 also need a matte screen to focus? Or is it just when using a converter with either the 280/2.8 or 105-280.4.2?
SH Photo is a very reliable, but expensive source for Leica products. There is rarely, if ever, a bargain. But if it is something you really want you can depend on the grading. This is my experience and I have bought 3 lenses from them over the past few years.Hah! Here it is! SH-Photo were brilliant:angel:, the German mail less so:angry:.
Anyway, demo as new in box, ROM too, as-new 1.4x extender, not ROM, both sitting right beside me. I will test the optics this weekend.
First impressions:
Zoom ring: firm and positive, not extremely smooth.
Focus: Very good and smooth, very long throw, but not the silky focussing of the 280/4.0 (but then, what is?) Focussing ring a bit narrow.
Focusses down to about 1.5 meters, making it nearly macro on the extender.
Well balanced on the DMR/R9. nice handrest, general impression:beautifully made.
From the ergonomic point of view a good choice for my use i.e. hard work in African wild-parks. It will probably stay welded on the camera with the converter, whilst the M8 will take care of shorter lengths up to 135. It is not a light combo, but well, I'm a big bloke . Definitely Upstrap territory.
I notice I will need a full matte screen.

I have a 400D, had a 200 1.8, and have a 105-280. The 400D, my AF is quite dodgy with 200 1.8.... Had a lot of luck focusing with normal focus screen and 105-280, this is probably under exposed a bit...As a matter of interest does the 280/2.8 also need a matte screen to focus? Or is it just when using a converter with either the 280/2.8 or 105-280.4.2?
euros, yes?Well, 2500 for the lens and 500 for the converter both of them demo ex+ grade was not expensive imo.
1.4x mounted and lens at 280, makes 400 @ just over 5.6, effective 520. Not bad for length and speed,and the full res images are great. The sheep, which I took in the distance I take most of my wildlife shots, was very convincing. I am itching to replace it with a leopard :ROTFL:euros, yes?
anyway, I am looking for a 1.4x and I asxszume it works on the 105-280 without interference. Some lenses (180 2.8? do not, something about rear lens too deep.
Images look great with 105-280 I assume yes? at what end (also with 1.4x?

Did you use the 2x apo for that? there is a huge difference between the non- apo and apo. I used the 2xapo often in my film days and it was excellent on the 2804.0apo, no need to stop down. Even stacking the two on the 280 yielded good results wide open (except in the far corners). The resulting 800/11 was a beast to handle, but it was doable with a beanbag. I see I need to pick up a 2x apo converter, reading my own post.I have not shot them side by side yet, but I feel the 105-280 @ 180 does outperform the venerable 3.4/180apo. What are your findings?The 2x on my 180/2.8 APO and on a test RobSteve did for me using his (now gone) 90 AA, it knocked the snot out of the resolution of both lenses. It got better if you went a further 2 or so stops down, but...
On the 105-280, RobS and I did a side-by-side test of it against my 180/2.8 APO and his 180/3.4 APO but we I don't think we tested any with converters.
