Hi, I've been having this chat in the M43 forum, and the conversation became specific enough that I thought I would ask if any of you have tried the following lens on a M43 configuration. I would like your opinions but please only if you have experience with these 2 specific lens : - Laowa 7.5mm for M43 (15mm equivalent) - Laowa 15mm Wide angle macro (30mm equivalent) I love the 15mm because of its capability to focus at 1:1 magnification, allowing for a subject very close to the lens to...

Hi, Could someone please help confirming my calculation ? Is the following correct ? >>> On a GH-4 M43 camera, the obtained angle of view on the sensor will be smaller with this Laowa 15mm ( https://www.venuslens.net/product/laowa-15mm-f/ ) than on this Lumix 14-45mm ( https://www.bhphotovideo.com/c/product/657970-REG/Panasonic_H_FS014045_Lumix_G_Vario_14.html ) ? That is surprising to me as the Laowa is a wide angle lens, and the Lumix isn't, but if I understand correctly, because of the...

My favorite landscape lens is the 21 Ltd, both for size and contrast. However, my last few vacations have gotten me thinking that I might want to add an ultra-wide zoom to complement it, as I often find myself needing to resort to stitching multiple shots together in order to fit an entire scene. There are worse things in the world, but it is time-consuming. So I’m looking at options, which has brought up two big issues for me. First, I’d want the IQ to be on par with the 21 Ltd, or at least...

Hi, I'm a new user, after a few years reading the forum I have newbie question to ask, currently looking for a macro lenses, I saw lots of threads about macro lens but I still cannot decide, therefore I'm looking for a feedback and explanation about macro.

I have 3 lenses 55/1.8 my favorite, 28-70mm jack of all trades, 12mm fisheye for some fun. Now I'm interested in...

I have a couple of Pentax Limited primes: the DA 15mm and the DA 35mm Macro, and would like to use them on my GH4, but as they do not have an aperture ring, I would loose aperture control if using a cheap m4/3 to K adaptor. Are there any 'automatic' adaptors available? - i.e. that would allow in-camera control of the Pentax lens aperture (and maybe also autofocus - though that not essential). Otherwise are there any basic 'non-auto' adaptors that you would recommend for quality? I'd be using...

I'm upgrading cameras every 5 years or so, my current is a K-5 - which has served me very well indeed. I'm not someone who wishes to acquire every latest slight step-up in technology: the K-5 is a great camera which I still use as a professional tool, yet 2x step up in resolution would help. So the K-1. I'm going to order one soon ...but lenses that do the 36MP justice? Pentax lenses I currently use: 15mm Limited: very very very amazing centre resolution, though poor corners; this lens I...

My not entirely reliable brain is telling me that I NEED to buy an Olympus 17mm F1.8 lens as my PanaLeica 15mm F1.7 isn't "a true 35mm FF equivalent lens". While I understand that this is technically correct, as a G7 user capturing OOC JPGs, am I: 1. Not going to see enough difference between the 2 FLs considering both lenses are excellent? 2. Going to be very upset that I don't get a snazzy lens hood free with the Olympus lens? 3. Still manage to take very average photographs at both FLs? 4....

GF1 is a very old horse now, but I love it very much. I am wondering if the aperture ring of the relatively new 15mm f1.7 Leica could be used on it? Does someone have experience with this combo? Many thanks, Peter

Hello all, I'm currently evaluating two copies of a Tamron 15-30mm, one purchased and another rented for comparison. For my purposes (storm photography), I'm mostly interested in infinity performance at 15mm. Multiple online reviews stated that this lens has a fairly flat field and is sharp edge to edge, but this is not what I'm experiencing. To test, I mounted the camera on a tripod, VC off, remote release, EFCS, etc. I used Live View autofocus to acquire focus on a distant white tower in...

There appear to be two versions of this lens, 'D EX' & 'EX DG'. Is anybody aware of the difference between the two lenses, and what this might mean to a full frame user? My best guess is that the G version may be restricted to use on newer bodies, but I'm clutching at straws.
