Haven't used either of the ones you mentioned, but the best one I have ever used is this: http://www.amazon.com/Rayovac-SE1WHLT-B-Sportsman-Function-Headlight/dp/B001H9NR76 I use it mainly as a work light. The diffuser, whiteness and high output are better than any other headlight I have used when working on wiring, making similar colors easy to differentiate. The blue LCD also emits enough near-UV to make it useful for finding automotive coolant leaks. If you don't need the diffuser, blue LED, voltage regulation or cool running, then Rayovac's 3-watt 85-lumen model that runs from 3AA cells might be more to your liking: http://www.amazon.com/Rayovac-Sportsman-Xtreme-3AA-size-Headlight/dp/B001KYFZL4 Both models were available at lower cost from a local WalMart when I bought the one I now use.

Without it being available yet it's hard to say just what exactly will be different quality wise. The new one will improve bokeh out of focus highlights at a price though. You will lose T-Stops (light transmission) For example 1.2 might give you the same light as f1.8-2. This is because the filter is a type of Neutral Density filter. For me I shoot low light and having that extra stop is important. The trade off combined with price just doesn't work. So what's more important to you? Bokeh quality or low light shooting? The 56mm is a fantastic lens in either version. Highly recommended!

I have both lenses. My experience is that both provides same good image quality. Lack of OIS i do not know.. I use the 25 mm more than the 45 mm now since i can use it for portraits by moving a bit and also "normal" day to day use

I don't have experience with those other lenses but I can tell you it is an amazing lens and worth every penny. I use it to shoot weddings and also do a lot of artistic shooting with it of flowers and stuff like that. The background blur is incredible.

Do as much research as possible but foremost, answer this question? What you want to achieve? Both are very capable and what you save with D7100 you can purchase quality lenses.

Awesome. Although for the MarkIII, I would get the same 85mm LSeries lens. Costs more.

It depends on your equipment and needs. My suggestion is to rent one from BorrowedLenses, they do have it and try it out before buying. I have done this with some recent L series lens purchases. It was much easier to make a decision on those fat lenses.

The biggest difference I find is that you can use optical zoom in movie mode with the H2. Also, H2 has Carl Zeiss lens which i think H1 doesn't

Both are fine. As to which is"preferred" that's up to you. I like the 20mm personally.

Hi Hydra, the reason why the SAL2470Z is more expensive that the SEL2470Z is because the SAL2470Z uses SSM (Super Sonic wave Motor), its a kind of motor that contributes to smooth and silent AF operation. The moter produces high torque at slow rotation, and provides immediate start and stop responses which makes autofocusing extremely quite. The other lens doesn't have it. -Ely

I've had the Kenko tubes as well as the Zeikos (which I use now). In my opinion, the Zeikos are better designed and build, i.e. they're sturdier and the auto focus works. The AF doesn't work with all three tubes together but it does work with a variety of combinations of the three.

I've used both and recommend the Niterider. The light output and features are roughly equivalent but the seals on the Solas are much better. The bottom seal failed on my first Cygolight. They replaced it under warranty and the service was excellent. A similar failure happened on my second Cygolight, allowing road salt into the device and corroding it. After that I bought the Niterider. The Niterider seals have a much better design and I've had no problems with them.

I don't specifically know the answer to your question... all i can say is that the one i purchased works as advertised. The only thing you could do is purchase a pair of both and have then assessed for quality lense grinding by your eye profesdional. Research Amazon products... they show several... then read all of the ratings. Hope these friendly suggestions are helpful.

I have had both versions of the lens and definitely preferred the one with IS. With that said, the difference in price is significant and the non-stabilized version produces superb images. If you are shooting outdoors with plenty of light it is perfect. If light is an issue when shooting I would definitely save up for the IS version.

The Nocticron IMO is better corrected and more Leica-like. The Voigtlanders get a tiny bit more light but the rendering is different. The 42.5/0.95 was excellent before the Nocticron was released but after comparing images from both, the Nocticron just seems to be better. The 25/0.95 is a different focal length but is also a fast lens which now has a clickless aperture ring. I'm a stills person so this is from a stills perspective. If you're into video, the Voigtlanders are tough to beat due to the clickless aperture rings. If you need optical stabilization however, the Nocticron is your best bet that is still fast and mid-telephoto. The Nocticron IMO is better corrected and more Leica-like.

I've had both IS and non IS, I have found that for the price this is a very handy lens to have. It works great outside, and as long as you have a semblance of a half way steady hand then not having the IS won't be a problem. Some of the issues you might encounter with this lens is when it comes to shooting in lower light situations, for example trying to take pictures inside especially at night if the room is not heavily lit. In that case the IS would help but that would only take you so far. Part of that is due to the lens speed. I found that if you take more pictures and try to stay aware of light you should do just fine. I love that this lens has the wide angle and the ability to super zoom. This has become my main travel lens, because of its versatility. For the price you can't beat it, I think its like $199 and just starting off as a new photographer its a good start. Yes there are better lenses out there BUT you will pay a Lot more for them as well.

I don't have both for a one on one comparison of the image quality, but the 35mm f2.8 macro generally has slightly better ratings. Check out the reviews on the Pentax Forums web site. The main reason I purchased it was for the macro capability. It also has metal vs plastic housing which may or may not be an issue depending on how you use it.
