NOT HAPPY with my DA 35mm F2.4AL
Mine seems OK on AF, but on manual focus it's going just beyond infinity which I'm not happy about. :cry: How are other people finding their's focuses on infinity? Spot on or just a bit off? Edit: The image in the viewfinder is good enough to focus on.

NOT HAPPY with my DA 35mm F2.4AL
I have just tested the one I've received against the 16-45mm f4 and the 31mm f1.8 Limited and its performance is well up to standard. It's very similar to the one I tested for EPZ a while back. Definitely worth its 4.5 star rating.

NOT HAPPY with my DA 35mm F2.4AL
It's usually telephoto lenses that focus beyond infinity, if such a place exists, simply because of expansion and contraction of the lens barrel causing a focus shift. So they don't really focus beyond infinity, it's just that the position of infinity changes slightly with temperature changes. Sm...

NOT HAPPY with my DA 35mm F2.4AL
Funnily enough, I'm not not happy, just uncertain at the moment. This is where I would say I am at the moment, much happier than after those first shots, but I can get good focus Manually and by using Liveview so I just need to regain confidence in the AF.

NOT HAPPY with my DA 35mm F2.4AL
Virtually all (if not all) my lenses focus slightly beyond infinity. On the AF lenses it's more noticeable, but even the old manual lenses need to be tweaked slightly back from the maximum focus to be 100% accurately focused to infinity.

To infinity ...... and beyond ......hey it out guns the Tamron, who cares if it looks blurred in the view finder. I had 60 images and I couldn't tell where I'd pointed the focus, so just picked f8 from the 2.4 and f5.6 from the Tamron (sweet aperture). Quick comp from LR3.6 :) DA35 on the rig...

DA35 on the right, resized down from screen capture on iMac You can't tell too much from one shot especially when you don't know where they are focussed. That's why I prefer lenses that work at infinity.... usually everything from about 5m to infinity is then in focus. It might be the lighting, b...

That's why I prefer lenses that work at infinity.... usually everything from about 5m to infinity is then in focus. If that's true it shouldn't really matter where the actual focus point is so long as it's sufficiently far away - if you get that sort of focus range at infinity, you should still get ...

cough cough, I had 5 mins! Cough, I'll be back there next week with my tripod and notebook, if I live that, cough, long .... I'm reassured DA35 is Sharp (more than Tan 17-50), I still need to test the issue of why it is OOF in the viewfinder. I don't have this with any other lens I have. D...

NOT HAPPY with my DA 35mm F2.4AL
Just done some quick tests on mine at f/5.6 by taking 3 shots of a chimney, one with it in the centre of the frame, one LHS and one RHS and there isn't much difference, which indicates that it is an excellent lens. The Jpg AWB colours were again spot on.:wink: Also tried infinity focus on a h...

[quote:3496ace15f="TheVicar"]Not had a single sharp shot wide open You have rigorously excluded camera shake? First comparison against Tamron used tripod, 2 second self timer & no SR. Other shots hand held with SR, as I stop down it gets sharper & shutter speed slower, so I think I can exclude cam...

NOT HAPPY with my DA 35mm F2.4AL
ChrisA Thankyou for your suggestions & advice, much appreciated, as always on on this forum. To adjust front or back focus on GX10 (K10D equivalent) I think you have to hack into debug, & it affects all lenses. I'm happy with AF on all my other lenses so don't want to tinker. I've boxed them both...

Recently I tend to mainly use my DA15 with the excellent F 35-70mm, sometimes with the M 75-150mm or K 135mm f2.5 for longer shots. The DA15 and F 35-70 make a great compact kit - the lens that's not on the camera can go in your pocket quite comfortably, but I tend to stow it in a compact camera bag...

Tokina 300mm and NPs 400mm both m42 and both have minimum focus distances of 5.5m approx so these are used when I don't think that I will get within 5.5 metres of wildlfe The 400mm is probably a T-Mount and you can change if for a K version (T or T2) for about £5 :wink: You can get closer with a ...
