billh Posted May 10, 2007 Share #1 Â Posted May 10, 2007 Advertisement (gone after registration) I have a 21 f2.8 ASPH, a 28f2.8 ASPH and a 35 f1.4 ASPH. I think I have to make a decision about which to buy to utilize the 30% off deal before the end of May. I mostly use the 35 f1.4 (and until I gave up because of back focus issues, I primarily used the 50 f1.4 ASPH). I very rarely use the 21 f2.8. Does anyone have both the 24 f2.8 and the 28 Summicron? If so, would you mind sharing your impressions of the image quality at wide apertures (f2.0, f2.8) and also the look and smoothness of the out of focus areas? I tend to mostly use the M8 inside, or in lower light situations, which is why the 28 Summicron appeals to me despite having the 28 f2.8 ASPH (which is a very sweet little lens). I believe the 28 Summicron is sharper than the 35 f1.4ASPH, but I am not sure this is the case because I have not used the 28 Summicron. Â The last issue is focusing accuracy - I seem to remember seeing posts from people having issues with back focus when using the 28 Summicron.

Advertisement Posted May 10, 2007 Posted May 10, 2007 Hi billh, Take a look here 28 f2.0 or 24 f2.8?. I'm sure you'll find what you were looking for!
innerimager Posted May 11, 2007 Share #2 Â Posted May 11, 2007 can't get more useful info anywhere than from reidreviews.com on these lenses and much more. well worth the subscription. best...Peter Link to post Share on other sites More sharing options...
billh Posted May 11, 2007 Author Share #3  Posted May 11, 2007 I did read the reviews, and my sense is Sean prefers the 24mm lens, but it is still not clear to me how the images from these two lenses compare - and this is why I posted the question - to get opinions. From what I could see on Sean’s site, the 24mm photos of the bottles are very, very sharp and contrasty, while the 28 f2.0 had a more gentle soft look in the photo of his daughter at f2.0. But that is only a couple of photos of different subjects, so it would be interesting to hear from someone (like Sean) who has used both of them.

mat_mcdermott Posted May 11, 2007 Share #4 Â Posted May 11, 2007 While I don't own both the 24 and 28 at the current time, the 28 seems to win out wide open and in the out of focus areas for me. It constantly amazes me how this lens can be so sharp (I sare say even unflatteringly sharp to skin if used close-up...) yet be so smooth at the same time. These thoughts may be biased by the fact that it lives on my M8 while I haven't used the 24 in a couple of years. If you go for the 28 I advise using an alternate lens hood to the supplied one as it's a monster. I use the hood for the 35 Summilux and it's much more convenient.

Hartmonstr Posted May 11, 2007 Share #5  Posted May 11, 2007 I had the same dilemma as you when designing my kit, Bill, and ended up going with the 28 for the extra stop in speed, and because it was right between the 50 Lux and the WATE which were also in the stable.  The 28 is amazingly sharp, even wide open. I posted this in the image forum this morning, but this shot of my son was taken after sunset with the M8 and Cron, f/2 @1/15 handheld at ISO 640. I printed a 16x20 on my Epson 4000 and the image is every bit as good as anything in my 1DsMkII kit.  My suggestion is to go to a dealer where you can put them on and do a side-by-side comparison. You'll be able to decide quickly which is better for you.  John Welcome, dear visitor!

I bought my 28/2.0 6 Weeks ago. I have it on my M8 most of the time. It is for sure the best 28mm on the market. Wounderful lense!! Link to post Share on other sites More sharing options...

Since I have the 28, I use the 24mm very seldom, sometimes only because of the little wider angle. But if it comes to portrait and an extra stop of speed and a nice boke(is that written correctly) the 28 is the best choice in my opinion. Link to post Share on other sites More sharing options...
woodda Posted May 11, 2007 Share #8  Posted May 11, 2007 I have the 21 f2.8 and tend to like this as it is a 28mm for the M8.

stunsworth Posted May 11, 2007 Share #9 Â Posted May 11, 2007 I'd stick with what you've got and buy a 50mm Summilux or 75mm Summicron. The 24mm is an excellent lens - I own one! - but it's a bit close to both the 21mm and 28mm. The 28mm Summicron only offers a 1 stop advantage over what you have. Â If you definitely want a 24mm or 28mm, I'd buy the 28mm Summicron and sell your existing 28mm. Link to post Share on other sites More sharing options...
billh Posted May 11, 2007 Author Share #10 Â Posted May 11, 2007 Hi Steve, Â I have the 50 f1.4ASPH and Noctilux, as well as the APO75, 75 Summilux and APO90. I love the APO75, plus it focuses accurately on my M8, so I use it quite a bit. I figure I might as well take advantage of the 30% off offer - here are the lenses I have: 21 f2.8ASPH, 28f2.8ASPH,35f1.4ASPH, Noctilux, 50f1.4ASPH, APO75, 75f1.4, APO90, 90f2.8 and APO134f4.0. I am mostly photographing people/events, and I tend to use the 35, 50 and 75 more than the others. If the 28 Summicron is sharper than the 35f1.4ASPH, I might end up using it more than the 35. The 24 interests me because it seems to be one of those exceptional Leica lenses. It is about (effectively) 32mm on the M8, but it is also a stop slower than the Summicron....Of course it is also a bit wider so perhaps I can get away with a slower shutter speed with it. Â The APO75, and to a large extent the 50f1.4ASPH are spectacularly sharp lenses in my opinion, plus the focus lengths work well for me. Does either the 24f2.8 or the 28 Summicron stand out like the above two lenses, or are they essentially equivalent? Â Bill Link to post Share on other sites More sharing options...
stunsworth Posted May 11, 2007 Share #11  Posted May 11, 2007 Bill, I see your problem - wish I had it too :-)  I don't have the 28 Summicron so I can't compare them, but here's a 24mm shot. Full frame, and a section from the bottom left corner - which should be where the lens is weakest - at 100%. No sharpening on wither (or levels/curves for that matter).  Ignore the 'artistic merit' of the shot - there isn't any, it was intended as a potential b&w study, but look at the detail captured.  Welcome, dear visitor!

innerimager Posted May 12, 2007 Share #18 Â Posted May 12, 2007 Steve- I left myself WAY open for that! ;>) Of course I have viewed many more artistic uses of this little masterpiece of a lens, but your image showed many of it's appealing qualities. That center image at 2.8 is stunning! Of course Mr. Reid and Mr. Erwin are culprits as well. I really want to train my eye for wider angle shooting, and intend for this to spend a lot of time on the M8. I got the 24mm finder the gentleman who sold it had and will use them on the M7 as well.

I agree that the hood is somewhat cumbersome in use, and I would be curious to know if someone has an alternative hood that they could recommend?
