Lenses / Re: Tamron 24-70 f/2.8 or Canon 24-105 f/4

« on: January 04, 2013, 02:39:56 PM »

Buying from third party companies like Tamron, theres all the time risk that something will be wrong. I have canon 550D and Tamron 17-50mm f2.8 VC for about three years. I'm not happy with 17-50mm f2.8 VC, difficult to get it sharp, its soft at f2.8, sometimes I get errors, time to time a lot of mist focus shots and sometimes I even not sure if it suppose to work like this. You must to get used to them and when you'll be able to make good shots.

I think you should do your homework before you buy your toys.  Tamron 17-50mm F/2.8 VC is soft from most of reviews.  However, the non VC version is very good.  Before I upgraded to FF, I was checking may reviews and even test Canon 17-55mm, Tamron 17-50mm VC, and Tamron 17-50 non-VC.  Canon 17-55mm was the best one and I had good time with the lens for about two years.  After I upgraded to FF, I used Canon 24-70 MK1.  Honestly, Canon 24-70 MK1 is not sharper than Canon 17-55 at all the time.  I believe that's because the IS feature on Canon 17-55mm.  I was so excited when Tamron released the 24-70mm VC.  After three months waiting for reviews, I decided to give the Tamron 24-70mm a try.  Guess what?  I sold my Canon 24-70mm in two weeks after I use the Tamron 24-70mm.  It's sharper than the Canon 24-70 MK1.  Moreover, I am happy with the VC feature.  I have some shutter speed about 1 second and they are still good.  That's almost impossible to happen on my old Canon 24-70mm.

Canon General / Re: Total File Size - All Your Images and Keep or Delete

« on: January 03, 2013, 01:02:09 PM »

I believe I keep only about 20% of my images.  I have about 100 to 200 GB photos, and some of them are from my old camera jpg files.  That's already too many files for me.  Thus, deleting images is very important for me.  Here is how I usually do nowadays.

1. Take photos.
2. Move them to my computer and decide which files I will keep.
3. Move the files I want to keep to my storage server
4. Do easy process for the files I need to share or keep for myself from lightroom
5. Output those files in JPG file format and store in a JPG subfolder
6. Synchronize the storage server with backup drive

I carry 80GB cards with me to those.

80GB memory cards? Never seen that. CF? SD?

I guess 32GB x2 + 16GB x1

I call the 6D the "warmed up 5D2". Slightly microwaved in a BPA-free container Its not a knock on the Camera, when they sell it for $1299 in a year during Christmas, I promise to pick one up

You won't see 1299 for 6D in two years.  If it drops to 1299, I will get one as a backup camera.

I have a canon 550d rebel and was considering the "jump" to FF.

The Canon 6d is in my budget. However the Nikon D800 is available (refurb) for $2,300.

I ask myself - why spend almost the same on the inferior 6d ? Why does canon seem to give less and charge more ?

If you don't have any EF lens, switching to Nikon may work for you.  Nowadays, third party lenses are amazing.  If you think the following lenses are you going to use, you could switch to to Nikon.

14-24(Nikon)
24-70(Tamron)
70-200(Tamron)
35mm(Sigma)
50mm(Sigma)
85mm(Sigma)

If you need other lenses, you have to consider Canon.

Third Party Manufacturers / Re: Sigma 35 f/1.4 DG HSM First Impressions

« on: December 25, 2012, 01:06:03 AM »

Here is CR.  I believe most people here are Canon fans, not Sigma fans.  You see many people post like "No red ring on it", "I buy only Canon", or even "I don't care how the reviews are, it's not Canon".
I assume you know how to use google search.  Please search Sigma 35mm F/1.4 review, and tell me how many reviews say Sigma/Canon better.  If you do believe most of the reviews, that's fine.  However, I believe there must a reason most reviews give Sigma the crown.  Don't even forget the price between Canon and Sigma is very different.

Actually this does not address issues raised in my post which you are not quoting...as to your reasoning "that lots of people say this is so" doesn't convince me any... rather some "group-think" is obvious and "me-too" blogs and reviews that follow the original lensrental format or even directly reference it...are not exactly "unbaised" nor always competent.

Lensrental's own blog, it must be said, is rather measured pointing out the bokeh could be a weak spot. I agree there are a couple more out there which I would believe but they are all careful to not over emphasize either the bokeh or the autofocus issues that may well emerge and rather stick to sharpness and the clear price advantage.

I had no beef about the better sharpness, but my posts (scroll back a few not just the last one) raises at least three seperate issues which none of the "Ra Ra Ra!!! reviews" address...certainly with no careful analysis or openly available data.

Only exception is lensrental blog which in fact reinforces the concern about the bokeh with graphs to boot!

I only quoted the part I disagree with you.  I won't waste my time to response the part I agree or cannot give a clear answer.
By the way, do you really try to do google search about the Sigma 35mm F/1.4?  Not all websites follow lensrental.com.  Many websites report the bokeh and autofocus of the new Sigma 35mm F/1.4 is amazing.  You can have your own opinion for the Sigma 35mm F/1.4.  However, I am just telling you many(or I should say most) webistes talking about the Sigma 35mm F/1.4 believe this is the new king of the 35mm prime.

Another issue is the over-hyping by the sigma fan club here....contrary to helping sigma's cause this sets the expectations so high  for the new lens that no real lens is going to be able to deliver all that and fix the morning coffee... What are you basing this on? All this started with Roger from lensrental suggesting it is sharp and for once he can give sigma the kudos for turning the corner ... But upon reading his further blogs (including a subsection in canon 35 f2 review where he provides some more info on the sigma 35 f1.4 ) he clearly indicates the bokeh is less than stellar with sigma. Interim, with most stores back ordered for this lens all we have is hype..and more hype.

EOS Bodies / Re: Canon Cannot Keep Screwing It's Customers Over

« on: December 21, 2012, 06:42:16 PM »

If I knew the camera would drop almost $1000 since release, I would have waited.
If I knew that I could purchase the camera for the same price that I did(at release) now, and get a free L lens... I would have waited
Point is, I believe that these price drops occured too soon.

Honestly, how many of you purchase items that drop this much of a price in 6 months?
when I purchase an iPhone, its the same price until... the next iphone comes out.

The flat screen TV that I purchased for $1500 when it came out almost a year ago, is till $1200

You know not ever smartphones can keep it value as good as iPhone.  Same thing here, camera price could drop very fast.  Remember the golden rule, supply and demand.

so you are saying depreciation bothers you.
5d's target consumer is pro's, who'll buy this cameras to make a living.  They are not going to complain about depreciation because they are making money with the equipment.
You can't afford depreciation, you can't afford the product.
Assume you buy a dress shirt for $50 today, you wear it, and try to sell it in 3 months.  How much do you think you'll get for that shirt?!!! $25?  You would not complain about that because you got your money's worth.
Go out and get your money's worth with the gear you bought.

True.  However, I think many 5D buyers are not PROs because three of my colleagues own 5D3.
You do see many people complain the price drop here and I believe most of them are not PROs.  If people really make money from their 5D3, they probably won't complain the price drop here.  I am the one pay for the highest price(~3000) for 5D3 in my company but I don't envy that my colleagues.  People need to realize depreciation happens.

If you are not really happy with Canon, you can switch to Nikon.  Nowadays Sigma makes some good prime lenses and Tamron makes some good zoom lenses in good prices.

If I had a 35L, I won't buy Sigma 35mm.  The depreciation of 35L is not worth for Sigma 35mm.  I am planning to get the Sigma 35mm because I don't have Canon 35mm L.

Lenses / Re: The great battle: primes vs zooms

« on: December 17, 2012, 05:25:27 PM »

For short range, I prefer primes.  Zoom for 100mm+.  Sometimes I also want to use primes because it's fast and DoF.

EOS Bodies / Re: YN 622; Is this the/a solution to 5D3 + AF beam = slower focus???

« on: December 17, 2012, 04:30:26 PM »

Thanks for sharing those useful information.  I don't need a wireless flash trigger, but I want a AF assist.  I think I am going to give yn622c a try.

I exchanged it for another new copy from the dealer and the 2nd body worked much better.

That's interesting.  Looks Canon has QC problem for its 5D3.
My 5D3 works fine for low light.  However, I still like to have a AF assist bean.  Dose anyone know if there is a small device for AF assist bean only.
