I was thinking this Lens Pen, has anyone got any experience using it?
Danielsan said:Looking to finally purchase a 50mm prime lens for my D3100. Still not sure whether to get the f/1.8 or the f/1.4. The latter being almost twice as expensive. The most important features that I want from the new lens are a great bokeh and great performance in low lit conditions. Is the on 1.4 worth the extra cash considering it is a long term investment?
Eww.tino said:There is a Photoshop plug-in called bokeh you can fake the bokeh of a 1.2 lens.
Of course it has some limitations.

Fujinon lenses for Canon?
Even if this doesn't happen the rumors about a mirrorless ILC Fuji X100 seem to be more and more prevalent. It would be awesome if we saw Fuji throw their weight in the lens market again. It will probably be for APS-C sensors though. Hopefully the things have a physical aperture ring so it can be used on an NEX!
tino said:I got a NEX-3 recently. I was cruising ebay one night and was randomly throwing NEX-3 and NEX-5 auctions to gixen in case I can catch a good deal.
I came across a gazelle auction that listed a "good" condition NEX-3 body for $310. Nowadays you pretty much can find a new NEX-3
body for $300 if you look hard. I noticed it has a "make your offer" option so just
for fun I made a lowball offer of $225. To my surprise I got the "offer accepted" email 1 second later. I realized they set a very low accepted price for this camera. I felt a little bit dumb afterward. I should have lowballed gazelle from $200! Hell I should have make an alternate account to test the bottom line.
So, I ended up joining the mirrorless army sooner than I expected. Choosing NEX was
a no-brainer for me. The whole world knew Nikon was going to release a (useless) 2.5X format EVIL, which turned out to be a 2.7X format. Canon, being so successful in the entry level DSLR market, has even less incentive to release an APS-C mirrorless camera to confuse its traditional "Rebel" buyers. So there is no way Canon will release a 1.6X EVIL that can adapt to their EOS lenses seamlessly. As for the Fujifilm 1.5X EVIL rumor.... I haven't heard enough "credible" rumor. Plus I am pretty sure I can't afford a Fuji system even if they commit to a 1.5X system.
The camera arrived. Besides the scratched shutter button and the bottom, everything looks find. The testing photos I took looked fine. I haven't test its ISO limit yet, but I think I won't go over 800 very often for this body.
Since I don't plan to buy any ugly NEX lenses so I ordered a Nikon NEX/G adopter right away. I got the version that has a tripod mount on ebay. I have played with it for two days so I thought I would post some hands on comment.
For Nikon lenses that have aperture rings, you just have to set the aperture ring on the adapter to open and set aperture on the lens itself. On new lenses that don't have aperture rings, you have to control it from the adapter. However the aperture ring is stepless. From wide open to the smallest aperture only turns a narrow 30-40 degree. I am going to have to put a sticker there and make my own aperture marks.
Here is how it look with an AIS 50mm 1.8 (the most "pancake" like Nikon AIS)
tino said:You want to use Fuji mirrorless lens on NEX? Why do you want to do that.
Most likely scenario Fuji will make a 1.5X body with a set of proprietary mirrorless lenses. But unlike the Samsung and the Ricoh designs, the Fuji version will actually look good.
Zyzyxxz said:its not a full frame either though right?
chaostrophy said:Yeah...I'd think the 7D and D7000 would be more appropriate cameras to compare it to.

Forsete said:7D: 854
D7000: 1167
A77 will probably benefit a little due to the large images it spits out.
captive said:Thats something people have talked about, the higher MP the more noise you get. Its simply laws of physics.
Sensitivity
Default: ISO 100 - 1600 in 1/3, 1/2 or 1.0 EV steps
Boost: 50 - 6400 in 1/3, 1/2 or 1.0 EV steps, HI2 = ISO 6400
Radec said:^
D3x? 12800?
It only goes upto 6400 bro
D3s and D3x are also full frame cameras. The Nex is a crop. And yes, it is all about physics. Namely pixel density.Radec said:nah, sensors improve everytime. It's just a matter of time before they can do a D3s ISO on a 20+ MP sensor.
It ain't physics if they can change it.
http://www.digital-photo-secrets.com/tip/333/do-more-megapixels-mean-better-photo-quality/But wait, I hear you say, these are incredibly small numbers! Why do camera makers keep making cameras with many more megapixels every year? The answer is simple. They need a reason to convince us in the public that the next model we buy will be a big upgrade from the one they we now. What better way to do it than with a number that steadily increases as camera makers make bigger sensors every year?
So, what is the lesson to be learned from all of this? Megapixels are great. They brought digital photography out of the dark ages and allowed photographers to make digital images that compare to film images. But megapixels are no reason to upgrade your current model. Instead, focus on a kind of image you would like to get and consider the limitations of your current camera model. You might need a different lens or a camera body that takes a quicker continuous stream of photos. If you do end up buying a new camera body, do it for reasons other than the fact that you will be getting more megapixels with it.
tokkun said:The A77 is 1/16 EV worse in low light performance than 7D and a bit less than 1/2 EV worse than the D7000.
That's not that bad considering the translucent mirror is supposed to cost 1/3 EV.
The A77's sensor has a very high dynamic range, so you are probably fine shooting at -0.5 EV and then fixing the exposure in post. It's a little extra hassle, but you ought to be able to get as good or better results with the A77.
That said, the 7D is 2 years old. I think people would have liked to see a more significant win for the A77. But I think that realistically you have to expect that SLTs are not going to be the top performers in high ISO and balance that against the benefits the technology brings to the table.
captive said:Not to mention what are you really gaining with more megapixels? Going from 12mp to say 24mp doesn't double your resolution.
The A77 earned an overall image-quality rating of Excellent from its lowest sensitivity of ISO 50 through ISO 400. At the heart of this assessment is the camera's Excellent rating in our resolution test, where it turned in 2770 lines per picture height. Compare that with the 18MP Canon 7D's 2610 lines or the 12.3MP Nikon D300s's 2340 lines, both at their lowest ISO settings of ISO 100.
Given that the Sony has so many more pixels than either of those cameras, you'd be right to expect even more resolving power, but Sony usually doesn't push hard to boost resolution. The A77 does hold a lot of its resolving power as ISO rises, though. At ISO 400, it barely dropped to 2720, while at ISO 1600 it held at 2620 lines
giga said:DPReview did post their studio comparison today of the A77. Chroma noise seems to be the difference.

Damaged said:Okay so my temporary lack of DSLR has made me look at my 35mm film SLR again and the cost of developing seems to have gone through the roof since I used to use it regularly.
This got me to thinking about processing my own Black and White negatives and scanning them in, I used to use a darkroom in college so know roughly what I'm doing and should be able to spool a roll of film in a dark bag. This kit on ebay seems to have all i'll need apart from the dark bag, chemicals and a couple of odds and sods (canister opener for fully wound back films ect...)
http://www.ebay.co.uk/itm/350490832...AX:IT&_trksid=p3984.m1423.l2649#ht_1942wt_952
Does anybody else in CameraGAF land do this or does anybody have any experience processing film at home? Could certainly use some pointers and advice with regards to what Kit would be needed.
jiji said:I processed film at home regularly for a couple of years. I bought my equipment as separate parts, rather than using a kit. That kit looks worthwhile, though the plastic tanks/reels have their own foibles (loading film can be tricky/inconsistent, uses more chemicals) and will eventually break down. I recommend an aluminum tank and steel reels (look for those by Hewes). Digital thermometers are accurate and don't drift, but they eat batteries quickly. You could probably use some additional graduated cylinders (one 500ml and one 50ml) for more accurate measurement of chemicals, plus a 5ml syringe for measuring developer syrup concentrate (Rodinal, HC-110, etc.). Also, pick up a few bottles for temporary storage of chemistry solutions.
You will also need clips for hanging your film up and a place to hang them that's relatively dust-free. A cheap vinyl garment hanger is great for this.
